# Bill of Materials (work in progress)
|
||||
|
||||
First working BoM is targeted for *mid-July '26*
|
||||
|
||||
A final, fully-costed BoM is targeted for *end of August '26*
|
||||
|
||||
Blog post - how I'm making this BOM [How-to: Source BOM for OOMWOO Open-Source Vacuum Robot](https://makerspet.com/blog/how-to-source-bom-for-oomwoo-open-source-vacuum-robot/)
|
||||
|
||||
Rationale in [docs/design-document.md](docs/design-document.md).

|
||||
|
||||
## Budget target
|
||||
|
||||
~$200 in sourced parts + a Raspberry Pi 5 (4 GB), aiming at the capability of a
|
||||
mid-range ($500–600) commercial vacuum with mopping, possibly premium obstacle detection (ToF +
|
||||
color camera + an NPU accelerator).
|
||||
|
||||
## Robot BoM (work in progress)
|
||||
|
||||

|
||||
> compatible for higher-suction models). Omit any model whose known suction contradicts the row.

||||
## Dock (by tier)
|
||||
|
||||
Three dock tiers share one robot base, released in order:
|
||||
|
||||
| Tier | Adds | Rough extra parts |
|
||||
|---|---|---|
|
||||
| Basic charge (first release) | charging only | printed housing + contacts/magnets + wall adapter + IR beacon |
|
||||
| Auto-empty | dust auto-emptying | dock fan + bin/bag + sealed port |
|
||||
| Auto-empty + wash + dry | mop wash + hot-air dry | clean + dirty tanks, 2 pumps, heater + fan, own ESP32 + WiFi controller |
|
||||
|
||||
## Sourcing strategy
|
||||
|
||||
- Print geometry, source mechanisms and wear items. See the print-vs-source table in
|
||||
[docs/design-document.md](docs/design-document.md#2-print-vs-source-strategy).
|
||||
- Spec wear parts (brushes, filters, wheel modules) in *common, abundant sizes* so
|
||||
builders can buy cheap universal replacements anywhere.
|
||||
- Per-module sourcing details will land in the relevant
|
||||
[contributions/](contributions) RFCs as they mature.
|
||||
|
||||
## How I calculate BoM costs
|
||||
|
||||
Prices for vacuum cleaner aftermarket parts have a wide spread (3x max/min as a ballpark).
|
||||
You can buy same part for, say, $15 or $30 or even $45.
|
||||
|
||||
Therefore, if you search [AliExpress](https://www.aliexpress.us/w/wholesale-roborock-s5-lidar.html)/eBay/Amazon
|
||||
for, say, "Roborock S5 LiDAR", you will likely see offers around $30.
|
||||
|
||||
There will probably several pages worth of those offers. And if you dig through those pages, you will probably start
|
||||
finding parts for $25.
|
||||
|
||||
If you are shopping on AliExpress, open a part listing and check for free coupon offers like "$2.00 off on $18.00".
|
||||
That brings your $25 price down to $23. Also, check the fine print in red font saying something like "$21.43 each, ≥ 3 pieces".
|
||||
|
||||
That's not the end of it. The next AliExpress trick is to wait for seasonal sales and promotions. Those happen relatively often.
|
||||
Sales and promotions can bring prices down even futher.
|
||||
|
||||
How can you get to the rock-bottom $15 price? Aftermarket parts prices depend on your search keywords.
|
||||
Try searching for multiple keyword variations: "Roborock S5 LDS", "Roborock S5 LiDAR", "original laser distance lds",
|
||||
"LDS02RR", "LDS02RR LiDAR", "Roborock LDS02RR", "LDS laser sensor for xiaomi Roborock" and so on. Be creative and persistent.
|
||||
Try searching Google "site:aliexpress.com lds02rr" and other variations. Be creative and persistent.
|
||||
|
||||
Combining all these methods is how you can get the rock bottom $15 price.
|
||||
|
||||
I record two prices for each part in the BoM table, for example "$15-$25".
|
||||
The first ($15) price is the rock bottom one that often requires a minimum purchase of 3 pieces - what I'd (or anyone) be paying putting together an OOMWOO all-parts-included convenience kit.
|
||||
The second ($25) price is what you can realistically get when purchasing 1 piece, *applying coupons* and doing *a few minutes of search*.
|
||||
|
||||
Why record the first price if requires a 3 pcs minimum? This is because I intend to assemble a convenient parts kit - and make it available to everyone.

## What this page will become
|
||||
|
||||
A complete, zero-to-hero guide: sourcing the parts, printing the chassis, assembling the
|
||||
robot, flashing the firmware, bringing up ROS2, and first clean — with photos and videos.
|
||||
We'll make it a clear, standalone guide the moment there's something to build.

## What is this?
|
||||
|
||||
OOMWOO is an *open-source home robot vacuum* you can build yourself, made for the
|
||||
Raspberry Pi, ROS2, Home Assistant, and 3D-printing communities. It uses an
|
||||
affordable 2D LiDAR to map your home and navigate on its own. Local, no
|
||||
cloud required for regular functionality, no vendor lock-in. Follow us building in public

## Contributing
|
||||
|
||||
Would you like to contribute? See [CONTRIBUTING](docs/CONTRIBUTING.md) for the full guide.
|
||||
|
||||
OOMWOO is organized to built by the community, massively *in parallel*.
|
||||
The vacuum and its software are subdivided into [modules](#requests-for-contributions), see list below.
|
||||
|
||||
A volunteer picks whatever module she wants and works on it whenever she wants.
|
||||
For *code and simulation* modules she builds her package in her *own repo* and sends
|
||||
a short PR *linking* it from the module; for *docs and specs* she contributes files
|
||||
in-tree under `contributions/module-name/<her-github-username>`. See
|
||||
[CONTRIBUTING](docs/CONTRIBUTING.md) for how this works.
|
||||
|
||||
Multiple developers are welcome to work on the same module.
|
||||
The best solution for each module surfaces over time, with the project master having the last call.
|
||||
|
||||
1. Pick a contribution from the [list below](#requests-for-contributions).
|
||||
2. [Let us know](https://github.com/makerspet/oomwoo/discussions) you're working on it and your progress.
|
||||
3. Check [ARCHITECTURE.md](docs/ARCHITECTURE.md) and
|
||||
[SOFTWARE_INTERFACES.md](docs/SOFTWARE_INTERFACES.md) for the system design
|
||||
and ROS2 interfaces.
|
||||
|
||||
## Requests for Contributions
|
||||
|
||||
Every module below is *actionable now* — build it against the Gazebo simulation
|
||||
([oomwoo-one](https://github.com/makerspet/oomwoo-one)) or a real *placeholder robot*
|
||||
(a [Proscenic M6 Pro connected to ROS2](https://makerspet.com/blog/tutorial-connect-robot-vacuum-cleaner-to-ros-2-proscenic-m6-pro/)),
|
||||
until OOMWOO hardware is ready. Pick one, tell us in
|
||||
[Discussions](https://github.com/makerspet/oomwoo/discussions), build it in your own
|
||||
repo (docs and specs go in-tree), and send a short PR linking it from the module.

## Design research
|
||||
|
||||
We reviewed the 2025–2026 consumer robot vacuum landscape (global + China-sourceable
|
||||
brands, all price tiers) to decide which solutions to copy and which to skip. Key
|
||||
takeaways for the build:
|
||||
|
||||
- *Suction is a sourcing problem, not an engineering one.* Real-world cleaning does
|
||||
*not* track advertised suction (Pa); ~$500 mid-tier models beat flagships. A
|
||||
moderate *sealed* sourced motor + a good brush + tight airflow sealing matches
|
||||
flagships — *no custom impeller needed.*
|
||||
- *"Never gets stuck" needs camera + AI sensor fusion*, not LiDAR alone — LiDAR is
|
||||
blind below its ~10 cm turret (cables, socks). v1 leans on the *bumper* for low
|
||||
obstacles; vision-based avoidance is a later / experimental goal, not an MVP promise.
|
||||
- *Anti-tangle brush:* a *tapered rubber roller* resists hair-wrap best (a top user
|
||||
complaint) and is easy to 3D-print.
|
||||
- *Mop:* a 3D-printed *dual-spinning* mop is competitive; the self-washing roller
|
||||
mop's edge is overstated and hard to replicate — skip it for now.
|
||||
|
||||
*Well-loved models worth studying:* Eufy Omni S2 (obstacle avoidance), Narwal Flow
|
||||
(roller mop), Ecovacs Deebot T90 Pro Omni (~$499 all-rounder), Dreame X40 Ultra
|
||||
(dual-spinning mop). *Dreame* is also the most [Valetudo](https://github.com/Hypfer/Valetudo)-rootable
|
||||
brand — the safest donor to study. *(Per-model rankings are directional, from
|
||||
single-run reviewer tests.)*
|
||||
|
||||
## About
|
||||
|
||||
The project name "OOMWOO" is a rotational ambigram - it reads the same flipped 180°, like the robot itself, roaming your floor in every direction.
|
||||
|
||||
The project is sponsored by makerspet.com and remake.ai. We are reusing their open-source solutions.
|
||||
- If you'd rather skip the parts hunt, a kit (motors, PCB, brushes, gaskets, LiDAR) will be available at [makerspet.com](https://makerspet.com), from the same maker behind this project. The kit is a convenience, never a requirement. *Everything here stays open.*
|
||||
- When we get to apps, [remake.ai](https://remake.ai) will be providing its robot apps platform and app store. Using the app store will be entirely optional. The vacuum will *always support cloud-free, local operation for regular functionality out-of-the-box*.

# First Clean: coverage cleaning with mapping and exploration (ROS2 package)
|
||||
|
||||
A ROS2 package for the robot's *first clean*. The vacuum starts with *no map*,
|
||||
cleans the whole reachable floor using coverage path planning, builds a map with
|
||||
SLAM *while* it cleans, and keeps exploring until the map is complete. Because the
|
||||
physical robot isn't built yet, this is a *Gazebo simulation*.
|
||||
|
||||
> *Status — ready to start work.* No need to wait for OOMWOO hardware — develop it in the
|
||||
> Gazebo sim ([urdf-gazebo-sim](../urdf-gazebo-sim)) or on the real
|
||||
> [placeholder Proscenic M6 Pro](https://makerspet.com/blog/tutorial-connect-robot-vacuum-cleaner-to-ros-2-proscenic-m6-pro/).
|
||||
> Say so in the [discussions](https://github.com/makerspet/oomwoo/discussions) so we can coordinate.
|
||||
|
||||
> *Scope.* This RFC is only the *first clean from scratch*. Operating on a *saved* map,
|
||||
> docking, recovery, floor-surface handling, and cleaning modes are deliberately *out of
|
||||
> scope* and live in their own RFCs:
|
||||
> [nav-localize](../nav-localize) (navigate / localize / resume a saved map),
|
||||
> [dock-cycle](../dock-cycle) (undock / dock / recharge),
|
||||
> [recovery-safety](../recovery-safety) (recovery & safety),
|
||||
> [floor-care](../floor-care) (wall/edge following, carpet vs hardwood, mop), and
|
||||
> [cleaning-jobs](../cleaning-jobs) (modes, zones, job orchestration).
|
||||
> Keep this package focused on producing a *complete map* and *full first-pass coverage*;
|
||||
> the others build on top of it.

# Request for Contribution - Instructions
|
||||
|
||||
- reproduce the baseline simulation first
|
||||
- follow the [Gazebo simulation setup instructions](https://makerspet.com/blog/tutorial-map-navigate-ros2-robot-in-simulation/) to run the diff-drive + LiDAR robot in the Living Room world
|
||||
- get [m-explore-ros2](https://github.com/kaiaai/m-explore-ros2) running for frontier exploration (see the [demo video](https://www.youtube.com/watch?v=81-9q7QfkHs&list=PLOSXKDW70aR8uA1IFahSKVuk5ODDfjTZV)) — this gives you mapping + exploration *without* cleaning
|
||||
- build on the [urdf-gazebo-sim RFC](../urdf-gazebo-sim) robot model, world(s) and bumper
|
||||
- post in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=) to let everyone know you're working on it, and post your progress
|
||||
- add coverage cleaning
|
||||
- the robot starts with *no prior map*
|
||||
- plan and execute a *coverage path* that cleans the whole reachable floor (e.g. boustrophedon / back-and-forth, plus corner and wall-edge handling)
|
||||
- build the map with *SLAM while cleaning* (e.g. slam_toolbox or cartographer) — mapping and cleaning happen together, not in separate passes
|
||||
- keep *exploring frontiers* until the map is complete, so no reachable area is missed
|
||||
- define and document a clear *done* condition (full coverage *and* complete map), then save the map
|
||||
- make it robust
|
||||
- *dynamic obstacles:* a person, pet, or object moving into the robot's path must not break coverage or mapping — the robot should replan and continue
|
||||
- *LiDAR-invisible static obstacles:* the LiDAR may report open floor the robot cannot actually reach (glass, objects below the LiDAR plane, thresholds, ledges). Detect these via *bumper* contact, mark them as obstacles, recover, and replan around them
|
||||
- react to *bumper events* (left switch, right switch, front bumper) published by the urdf-gazebo-sim bumper
|
||||
- never get permanently stuck — recover from collisions and wedged situations (a basic local recovery here; the full recovery ladder lives in [recovery-safety](../recovery-safety))
|
||||
- test it well
|
||||
- start the robot from *various initial locations* and verify it still achieves full coverage and a complete map
|
||||
- add *regression tests* (headless, CI-friendly) that verify both:
|
||||
- *map completeness* — the built map covers the whole reachable area
|
||||
- *coverage completeness* — the cleaning path covers the whole reachable floor
|
||||
- test recovery from dynamic obstacles and from bumper hits on LiDAR-invisible obstacles
|
||||
- additional Gazebo worlds (highly valued)
|
||||
- create and test extra worlds: *multiple rooms, different floorplans*, narrow passages, furniture, and LiDAR-invisible obstacles
|
||||
- contribute these worlds back — they help everyone test
|
||||
- submit a PR (pull request) to `contributions/clean-and-map/<your-github-username>/`
|
||||
- link to ROS2 package(s)
|
||||
- instructions, documentation - how to install, run, configure, troubleshoot, test results
|
||||
- the Gazebo worlds you added
|
||||
- videos of full clean-and-map runs from several start poses
|
||||
- announce your submission in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=)
|
||||
- iterate with review
|
||||
- TBD, expect the RFC to evolve
|
||||
|
||||
## Acceptance criteria
|
||||
|
||||
Objective, measurable. Examples:
|
||||
- Starting with no map in the Living Room world, from *multiple initial poses*, the robot:
|
||||
- achieves *full coverage* of the reachable floor
|
||||
- builds a *complete map* of the reachable area
|
||||
- detects a clear done condition and saves the map
|
||||
- Robust to *dynamic obstacles* — a moving obstacle in the path does not break coverage or mapping
|
||||
- Robust to *LiDAR-invisible static obstacles* — bumper contacts are detected, the obstacle is marked and avoided, the robot replans and does not get stuck
|
||||
- Reacts correctly to *left / right / front bumper* events
|
||||
- *Regression tests* pass and verify both map completeness and coverage completeness, runnable headless in CI
|
||||
- Works in at least one *additional multi-room / different floorplan* world
|
||||
- Documented and reliably reproducible by someone else
|
||||
- TBD, expect criteria to evolve
|
||||
|
||||
The maintainer selects among compliant candidates using these criteria. Multiple
|
||||
attempts are welcome and useful even if not selected — modules are swappable, and
|
||||
a non-selected design is still a valid learning exercise and a fallback.

# Cleaning Modes, Zones & Job Orchestration (ROS2 package)
|
||||
|
||||
The user-facing *"what and where to clean,"* plus managing *long jobs*. This
|
||||
package adds cleaning *modes* (regular whole-floor, spot), *virtual walls /
|
||||
no-go zones*, *segmenting the map into rooms*, and a *job orchestrator* that
|
||||
splits a clean into manageable pieces — pausing to *recharge, auto-empty, or wash
|
||||
the mop*, then *resuming where it left off*. Because the physical robot isn't
|
||||
built yet, this is a *Gazebo simulation*; it is later re-validated on hardware in
|
||||
the [live-robot-bringup RFC](../live-robot-bringup).

# Compute Benchmark & Memory Reduction
|
||||
|
||||
Measure whether OOMWOO can keep ROS2/Nav2/SLAM onboard while reducing the
|
||||
minimum compute target from a comfortable 4 GB class system toward a practical
|
||||
2 GB class system.
|
||||
|
||||
This module is for repeatable measurements, not guesses. It should help compare
|
||||
Python/C++ ROS2 nodes, ROS2 composable-node layouts where supported, process
|
||||
layout changes, and later optional Rust experiments under the same workload.
|
||||
|
||||
> Status: in progress. Use the ROS2 Jazzy development container and the current
|
||||
> simulation stack where possible. Hardware runs on Pi 4, CM4, CM5, or compatible
|
||||
> modules are especially useful when available.
|
||||
|
||||
## Current Working Assumptions
|
||||
|
||||
- The consumer vacuum profile keeps SLAM and navigation onboard.
|
||||
- The practical near-term target is Pi 4 / CM4-class compute with 4 GB RAM.
|
||||
- The stretch target is to reduce the minimum memory requirement toward 2 GB
|
||||
without giving up ROS2.
|
||||
- The compute-module direction is CM4/CM5 or compatible modules on a carrier
|
||||
board; ignore the older RK3562 reference path.
|
||||
- The MCU owns motors, sensors, safety, battery/charging supervision, watchdogs,
|
||||
and the custom serial protocol.
|
||||
- STM32G070RBT6 is a strong MCU candidate because of its GPIO/ADC count, low
|
||||
cost, and LQFP manufacturability, while the MCU choice remains reviewable.
|
||||
- The MVP 2D LiDAR target is 5 Hz with no scan dropping.
|
||||
- Rust/rclrs is an optional late-summer integration candidate, not a baseline
|
||||
dependency today.
|
||||
|
||||
Context: this module follows the compute discussion in
|
||||
[issue #18](https://github.com/makerspet/oomwoo/issues/18).
|
||||
|
||||
## Request For Contribution
|
||||
|
||||
Submit a benchmark contribution under:
|
||||
|
||||
```text
|
||||
contributions/compute-benchmark/<your-github-username>/
|
||||
```
|
||||
|
||||
Include:
|
||||
|
||||
- a reproducible benchmark plan
|
||||
- scripts that capture RSS/PSS/CPU/startup timing where possible
|
||||
- a hardware/software run matrix
|
||||
- a compute BOM table with regional price and stock fields
|
||||
- clear notes on ROS distro, RMW, hardware, RAM size, LiDAR rate, and scenario
|
||||
- a short decision record after measurements
|
||||
|
||||
## Metrics
|
||||
|
||||
Minimum useful metrics:
|
||||
|
||||
| Metric | Why it matters |
|
||||
|---|---|
|
||||
| RSS/PSS per process | Shows where memory is actually going. |
|
||||
| CPU idle / mapping / navigation | Separates always-on cost from workload cost. |
|
||||
| Startup time | Exposes heavy node initialization and launch overhead. |
|
||||
| LiDAR update rate | Confirms the benchmark is not cheating by dropping scans. |
|
||||
| Nav2/SLAM headroom | Determines whether 2 GB is plausible with ROS2 retained. |
|
||||
| Recovery-event latency | Keeps safety-adjacent nodes honest under optimization. |
|
||||
|
||||
## Strategies To Compare
|
||||
|
||||
1. Current Python/C++ baseline.
|
||||
2. ROS2 composable nodes where supported, plus launch/process layout changes.
|
||||
3. C++/rclcpp for selected hot or always-on custom nodes.
|
||||
4. Optional Rust/rclrs spike for selected custom nodes after dev-image setup is
|
||||
reproducible.
|
||||
|
||||
Rust should only move from optional to recommended if it demonstrates a useful
|
||||
RSS/PSS or latency improvement and does not make the default Jazzy developer
|
||||
experience fragile.
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
- Measurements are reproducible by another contributor.
|
||||
- The benchmark records hardware, RAM, ROS distro, RMW, scenario, and git SHA.
|
||||
- Results distinguish process RSS from PSS when PSS is available.
|
||||
- Benchmarks do not reduce LiDAR update rate below the target unless explicitly
|
||||
marked as an experiment.
|
||||
- The contribution explains whether the result supports 4 GB only, 2 GB as a
|
||||
stretch target, or a different hardware class.
|
||||
- BOM notes include module/board, carrier, power, cooling, storage, MCU add-ons,
|
||||
regional price, and stock status.

# Compute Benchmark Plan by xbattlax
|
||||
|
||||
This contribution turns the compute discussion in issue #18 into a concrete
|
||||
benchmark scaffold for OOMWOO.
|
||||
|
||||
The immediate goal is to measure whether OOMWOO can keep onboard ROS2, Nav2, and
|
||||
SLAM while reducing the practical memory target from 4 GB toward 2 GB. The first
|
||||
optimization path should be ROS2 composable nodes where supported, plus
|
||||
launch/process layout. Rust with rclrs is kept as a serious optional spike for
|
||||
late August / September 2026, gated by measurements and dev-image
|
||||
reproducibility.
|
||||
|
||||
## Scope
|
||||
|
||||
Included:
|
||||
|
||||
- a Linux `/proc`-based process sampler for RSS/PSS/CPU
|
||||
- a run matrix template for repeatable benchmark scenarios
|
||||
- a compute BOM template for board/module, carrier, power, cooling, storage,
|
||||
MCU add-ons, regional pricing, and stock status
|
||||
- a short architecture decision record for the current memory-reduction plan
|
||||
|
||||
Not included yet:
|
||||
|
||||
- a Rust/rclrs node implementation
|
||||
- a C++/rclcpp equivalent node
|
||||
- physical Pi 4 / CM4 / CM5 results
|
||||
- automated launch files for full SLAM/Nav2 runs
|
||||
|
||||
## Hardware Profiles To Record
|
||||
|
||||
| Profile | Purpose | Notes |
|
||||
|---|---|---|
|
||||
| Dev machine | Reference only | Useful for repeatability, not a robot target. |
|
||||
| Pi 4 4 GB | Minimum prior-art target | Validate onboard SLAM/Nav2 feasibility. |
|
||||
| CM4 4 GB | Consumer carrier-board target | Low profile and product-friendly. |
|
||||
| CM5 4 GB+ | Higher headroom target | Useful if camera/NPU alternatives are evaluated. |
|
||||
| 2 GB class SBC/module | Stretch target | Requires real measured headroom, not assumptions. |
|
||||
| ESP32 educational profile | Offboard ROS2/SLAM learning setup | Not a consumer autonomous vacuum profile. |
|
||||
|
||||
## Measurement Scenarios
|
||||
|
||||
Start with these scenarios:
|
||||
|
||||
1. ROS2 graph idle after launch.
|
||||
2. SLAM running with 5 Hz LiDAR input and no scan dropping.
|
||||
3. Nav2 navigating on a known map.
|
||||
4. Recovery/safety node idle.
|
||||
5. Recovery/safety event burst.
|
||||
6. Same workload after composable-node or process-layout changes.
|
||||
7. Later: same selected custom node in Python, C++/rclcpp, and Rust/rclrs.
|
||||
|
||||
## Using The Sampler
|
||||
|
||||
Run this inside the Linux ROS2 environment while the target workload is already
|
||||
running:
|
||||
|
||||
```bash
|
||||
bash contributions/compute-benchmark/xbattlax/scripts/measure_ros_processes.sh \
|
||||
--pattern 'ros2|component_container|python3|slam_toolbox|nav2' \
|
||||
--duration 60 \
|
||||
--interval 2 \
|
||||
--label slam_5hz_baseline \
|
||||
--output /tmp/oomwoo-slam-5hz-baseline.csv
|
||||
```
|
||||
|
||||
The script writes CSV with:
|
||||
|
||||
- timestamp
|
||||
- sample index
|
||||
- label
|
||||
- PID
|
||||
- process name
|
||||
- CPU percent
|
||||
- RSS KiB
|
||||
- PSS KiB when `/proc/<pid>/smaps_rollup` is available
|
||||
- command line
|
||||
|
||||
PSS is usually more useful than RSS for ROS2 systems because shared libraries and
|

middleware pages can make RSS look worse than the actual proportional memory
|
||||
pressure.
|

## Templates
|
||||
|
||||
- `templates/run_matrix.csv`: planned benchmark runs and environment details.
|
||||
- `templates/compute_bom.csv`: compute BOM and regional stock/price snapshot.
|
||||
|
||||
Copy the templates into a results folder for real benchmark submissions. Do not
|
||||
edit old result rows after a run; add a new row for a new measurement.
|
||||
|
||||
## Expected Decision Output
|
||||
|
||||
Each benchmark batch should end with a short note:
|
||||
|
||||
- current measured minimum RAM class
|
||||
- biggest memory users
|
||||
- whether composable nodes helped
|
||||
- whether any Python node is worth porting to C++ or Rust
|
||||
- whether Rust/rclrs setup is reproducible enough to keep testing
|
||||
- what hardware profile the result supports

# ADR 0001: Memory-Reduction Strategy
|
||||
|
||||
## Status
|
||||
|
||||
Proposed.
|
||||
|
||||
## Context
|
||||
|
||||
OOMWOO should remain approachable for builders, so the first consumer vacuum
|
||||
profile should run SLAM and navigation onboard. Requiring a separate workstation
|
||||
for mapping would make the regular product harder to build and use.
|
||||
|
||||
The maintainer has clarified these current assumptions:
|
||||
|
||||
- Pi 4 / CM4-class compute with 4 GB RAM is a realistic near-term baseline.
|
||||
- Reducing toward 2 GB while keeping ROS2 would be valuable.
|
||||
- CM4/CM5 or compatible modules are the compute-module direction.
|
||||
- The older RK3562 reference schematic should be ignored for new compute-module
|
||||
planning.
|
||||
- The MCU role is fixed around motors, sensors, safety, battery/charging
|
||||
control, watchdogs, and custom serial protocol.
|
||||
- ESP32/micro-ROS is better suited to an educational/offboard profile than to
|
||||
the consumer safety/controller role.
|
||||
|
||||
## Decision
|
||||
|
||||
Use this priority order for memory-reduction work:
|
||||
|
||||
1. Measure the current Python/C++ ROS2 baseline.
|
||||
2. Try ROS2 composable nodes where supported, plus launch/process layout
|
||||
improvements first.
|
||||
3. Consider C++/rclcpp for selected memory-heavy or latency-sensitive custom
|
||||
nodes when composable layout is insufficient.
|
||||
4. Keep Rust/rclrs as an optional late-summer 2026 spike for selected custom
|
||||
nodes, not as a baseline dependency today.
|
||||
|
||||
Rust/rclrs should be evaluated seriously, but only promoted if:
|
||||
|
||||
- RSS/PSS or latency wins are meaningful against Python and C++ baselines
|
||||
- the Jazzy build/setup is reproducible in the OOMWOO dev image
|
||||
- contributor onboarding remains reasonable
|
||||
- the node selected for porting is small enough to keep the experiment bounded
|
||||
|
||||
## Consequences
|
||||
|
||||
- The first benchmark contribution can avoid adding Rust dependencies.
|
||||
- The benchmark still leaves a clear path for a later rclrs experiment.
|
||||
- The project can pursue the 4 GB -> 2 GB target with lower dependency risk.
|
||||
- Results should identify whether memory pressure comes from custom Python
|
||||
nodes, ROS2 process layout, Nav2/SLAM, or other runtime overhead.
|
||||
|
||||
## Open Questions
|
||||
|
||||
- Which launch graph should be the canonical benchmark workload?
|
||||
- Which ROS2 RMW should be the baseline for memory measurements?
|
||||
- Which node is the best first Rust/rclrs candidate if measurements justify it?
|
||||
- How should PSS be collected on target hardware when permissions differ?
|
||||
- What minimum headroom should qualify a 2 GB target as realistic?

# Dock Cycle: undock, dock, recharge & station services (ROS2 package)
|
||||
|
||||
Everything around the charging/service *dock*. The robot must *undock* at the
|
||||
start of a job, *return to the dock* (on completion or on low battery), *dock
|
||||
precisely* to make charge contact, trigger *dock station services* (recharge,
|
||||
and — where the dock supports them — auto-empty and mop-wash), and *find the dock
|
||||
when it is lost* and relocalization has already failed. Because the physical robot
|
||||
isn't built yet, this is a *Gazebo simulation*; it is later re-validated on
|
||||
hardware in the [live-robot-bringup RFC](../live-robot-bringup).
|
||||
|
||||
> *Status — ready to start work.* No need to wait for OOMWOO hardware — develop it in the

# Request for Contribution - Instructions
|
||||
|
||||
- model the dock in Gazebo
|
||||
- add charge contacts and a *detectable marker* for the final approach (IR beacon, fiducial/AprilTag, or a reflective-intensity pattern the LiDAR can see)
|
||||
- model a *battery* (drain during cleaning, charge curve while docked) so low-battery behavior can be tested
|
||||
- model a *generic basic dock* (contacts + a detectable marker); exact geometry TBD
|
||||
- post in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=) to let everyone know you're working on it, and post your progress
|
||||
- undocking
|
||||
- safely back / drive out of the dock to a known start pose, then hand off to cleaning
|
||||
- return-to-dock
|
||||
- navigate to the dock vicinity, triggered by *job complete* OR *low battery / full bin / mop needs washing* mid-job (coordinate with [cleaning-jobs](../cleaning-jobs))
|
||||
- precise docking
|
||||
- final approach using the dock marker; align to the charge contacts; *confirm charging started*
|
||||
- dock station services
|
||||
- once docked, trigger and wait for *recharge*, and — where the dock supports them — *auto-empty* and *mop-wash*; report completion so the job can resume
|
||||
- find-the-dock-when-lost
|
||||
- fallback used when [nav-localize](../nav-localize) relocalization has *failed*: run a search pattern to reacquire the dock marker, dock, and re-establish pose from the known dock location
|
||||
- test it well
|
||||
- start from *various poses and battery levels*; verify undock → clean → return → dock → service → resume
|
||||
- *kidnap* the robot so relocalization fails and verify find-the-dock recovers it
|
||||
- regression tests (headless, CI-friendly)
|
||||
- docking success rate and final alignment error
|
||||
- find-the-dock success rate from random lost poses
|
||||
- low-battery return-then-resume completes without losing the job
|
||||
- submit a PR (pull request) to `contributions/dock-cycle/<your-github-username>/`
|
||||
- link to ROS2 package(s) and the dock model / world additions
|
||||
- instructions, documentation - how to install, run, configure, troubleshoot, test results
|
||||
- videos of docking, find-the-dock, and low-battery return-and-resume
|
||||
- announce your submission in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=)
|
||||
- iterate with review
|
||||
- TBD, expect the RFC to evolve
|
||||
|
||||
## Acceptance criteria
|
||||
|
||||
Objective, measurable. Examples:
|
||||
- Robot *undocks* reliably to a known start pose
|
||||
- Robot *returns and docks precisely*, making charge contact, from various poses (alignment within a stated tolerance)
|
||||
- *Station services* (recharge; auto-empty / mop-wash where modeled) are triggered, completed, and reported
|
||||
- *Low-battery mid-job* triggers return-to-dock and the job resumes after charging
|
||||
- *Find-the-dock-when-lost* recovers a kidnapped robot after relocalization fails
|
||||
- *Regression tests* pass (dock success, alignment error, find-the-dock success), runnable headless in CI
|
||||
- Documented and reliably reproducible by someone else
|
||||
- TBD, expect criteria to evolve

||||
|
||||
The maintainer selects among compliant candidates using these criteria. Multiple
|
||||
attempts are welcome and useful even if not selected — modules are swappable, and

a non-selected design is still a valid learning exercise and a fallback.

# Dust Bin (mechanical module)

# Floor-Surface Handling & Edge Cleaning (ROS2 package)

Clean *better* by adapting to the floor. This package adds *wall following* (to

# I/O + Motor-Driver PCB (hardware / KiCad)
|
||||
|
||||
The custom board that connects every OOMWOO motor and sensor to the SBC: an STM32 MCU,
|
||||
motor drivers, sensor front-ends, and battery charging on one PCB. The MCU runs firmware /
|
||||
micro-ROS and talks to the Raspberry Pi 5 SBC over a serial / USB link.
|
||||
|
||||
> *Design basis:* OOMWOO v1 uses a *separate Raspberry Pi 5* as the SBC (ROS2, Nav2, SLAM),
|
||||
> so this board is a *pure I/O + power board* — no application processor on it. There is a
|
||||
> starting-point reference schematic (an RK3562 + STM32 combined design), but the on-board
|
||||
> Rockchip SoC and its whole subsystem are *removed*; only the STM32 I/O side is kept and
|
||||
> converted to KiCad for review.

# Request for Contribution — Instructions
|
||||
|
||||
Deliver a *KiCad schematic* derived from the reference PDF, trimmed to the I/O side and
|
||||
updated for OOMWOO, then *hold for review before PCB layout*.
|
||||
|
||||
- *Remove the Rockchip subsystem entirely* — the RK3562 SoC and everything that exists only
|
||||
to support it: *LPDDR4 DRAM, eMMC, the SoC PMIC / SoC-specific power rails (VCCIO, PMU / OSC
|
||||
/ PLL), the DDR PHY, the USB / PCIe PHY, and the MIPI camera interface*. Heavy compute and
|
||||
the camera live on the Raspberry Pi 5 SBC, not this board.
|
||||
- *Remove the WiFi / BT module* (AP6256) — WiFi/BT is provided by the SBC.
|
||||
- *Keep and convert to KiCad the I/O side:*
|
||||
- *STM32G070* MCU + support (clock, decoupling, debug / boot, the serial / USB link to the SBC)
|
||||
- *motor drivers* — drive wheels (×2), main brush, side brush, water pump, mop lift / spin
|
||||
(if fitted); put the *suction fan on an external ESC* (one PWM line) to save MCU pins
|
||||
- *sensor front-ends* — cliff / anti-fall IR, docking IR + bumper, side-proximity IR, bumper
|
||||
switches, IMU, LiDAR interface, multizone ToF, ultrasonic carpet sensor
|
||||
- *battery charging + protection / BMS*, and the board power rails that feed the STM32 /
|
||||
sensors / motors (keep these; remove only the SoC-specific rails)
|
||||
- speaker + amp, mic, buttons, LEDs
|
||||
- *Move the battery from 3S to 4S* — OOMWOO targets *~14.8 V* (see [BOM.md](../../BOM.md)). The
|
||||
reference appears to be 3S; update the pack, the charge-IC configuration, the protection, and
|
||||
any cell-count-dependent dividers / thresholds to *4S*.
|
||||
- *Wire the drive-wheel connectors* to the JST PH2.0 6-pin pinout above (verified against the
|
||||
sourced module).
|
||||
- assume battery Xiaomi/Roborock/Dreame BRR-2P4S-5200
|
||||
- *Convert the kept design to KiCad* (from Altium); keep a clean, readable, hierarchical schematic.
|
||||
- *Hold here for review.* Deliver the trimmed, 4S, KiCad *schematic* and stop — the maintainer
|
||||
reviews before anyone starts PCB layout / manufacturing.
|
||||
- *Submit* a PR to `contributions/io-pcb/<your-github-username>/` with the KiCad project, a short
|
||||
sub-BoM, and notes; announce it in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=).
|
||||
- iterate with review
|
||||
- TBD, expect the RFC to evolve
|
||||
|

## Acceptance criteria (schematic-hold milestone)
|
||||
|
||||
- The *entire Rockchip subsystem* (SoC, DRAM, eMMC, PMIC / VCCIO / PMU / PLL, DDR + USB/PCIe
|
||||
PHY, MIPI camera) and the *WiFi / BT module* are removed.
|
||||
- The *kept blocks* (STM32G070, motor drivers, sensor front-ends, battery charging, audio,
|
||||
buttons / LEDs, SBC link) are present, correct, and complete in *KiCad*.
|
||||
- Battery as specified
|
||||
- Drive-wheel connectors match the referenced pinout (JST PH2.0 6-pin), reconciled with part-specs.
|
||||
- Delivered as a buildable *KiCad project*; *ERC clean*; a sub-BoM and short design notes included.
|
||||
- Stops at the reviewed *schematic* — no PCB layout yet.
|
||||
- Documented and reproducible.
|
||||
- TBD, expect criteria to evolve.
|
||||
|
||||
The maintainer intends to *accelerate* this module and may commission a contributor to do it;
|
||||
community submissions are still welcome and reviewed the same way. The maintainer selects among
|
||||
compliant candidates using these criteria — multiple attempts are welcome and useful even if

not selected.

# Localization & Navigation on a Known Map (ROS2 package)

|
||||
Once the [first clean](../clean-and-map) has produced a map, the robot must be able

||||
to *operate on that saved map*: localize itself, navigate to any goal with Nav2,
|
||||
recover its pose when it gets *lost* or is picked up and moved (the *kidnapped
|
||||
robot* problem), and *resume an unfinished map*. Because the physical robot isn't
|
||||
built yet, this is a *Gazebo simulation*; it is later re-validated on hardware in
|
||||
the [live-robot-bringup RFC](../live-robot-bringup).

- reproduce the baseline first
|

- load a map saved by [clean-and-map](../clean-and-map) and bring up Nav2 + a localizer (AMCL or slam_toolbox localization mode) on the [urdf-gazebo-sim](../urdf-gazebo-sim) robot
|
||||
- post in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=) to let everyone know you're working on it, and post your progress
|
||||
- localization on a known map
|
||||
- *global initial localization at startup* without being given a pose (e.g. AMCL global init / scan-matching) — the robot figures out where it is on the saved map
|
||||
- track pose reliably during navigation; expose a localization-confidence signal (covariance / scan-match score)
|

- navigation
|
||||
- Nav2 navigate-to-pose and navigate-through-poses to arbitrary goals on the saved map
|
||||
- obey dynamic obstacles via the local costmap
|
||||
- lost / kidnapped recovery
|
||||
- *detect* when localization confidence drops (low score, high covariance, or a detected pickup/kidnap)
|
||||
- *relocalize*: rotate in place and/or drive to gather scans until the pose re-converges
|
||||
- define a clear *"relocalized" success condition*, and what happens if it *fails* — hand off to the [dock-cycle](../dock-cycle) *find-the-dock-when-lost* fallback
|
||||
- resume an unfinished map
|
||||
- load a *partial / serialized SLAM session* (e.g. slam_toolbox serialization) and *continue mapping where it left off*, merging newly seen areas into the existing map without corrupting it
|
||||
- test it well
|
||||
- start from *many initial poses*, including a wrong or unknown initial pose
|
||||
- *kidnap* the robot mid-run (teleport it in sim) and verify it recovers
|
||||
- resume from several partial maps and verify the merged map is correct
|
||||
- regression tests (headless, CI-friendly)
|
||||
- relocalization success rate from random poses
|
||||
- navigation success rate to random reachable goals
|
||||
- map-resume correctness (resumed + continued map matches a from-scratch map of the same world)

- submit a PR (pull request) to `contributions/nav-localize/<your-github-username>/`
|
||||
- link to ROS2 package(s)
|
||||
- instructions, documentation - how to install, run, configure, troubleshoot, test results
|
||||
- videos of relocalization-when-lost and map-resume runs
|
||||
- announce your submission in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=)
|
||||
- iterate with review
|
||||
- TBD, expect the RFC to evolve
|
||||
|
||||
## Acceptance criteria
|
||||
|
||||
Objective, measurable. Examples:
|
||||
- On a saved map, from an *unknown initial pose*, the robot performs global localization and converges to the correct pose
|
||||
- Nav2 navigation reaches arbitrary reachable goals reliably, avoiding dynamic obstacles
|
||||
- When *lost / kidnapped*, the robot detects it, relocalizes, and resumes — or cleanly hands off to the find-the-dock fallback when relocalization fails
|
||||
- An *unfinished map* can be loaded and mapping continued, producing a complete, uncorrupted map
|
||||
- *Regression tests* pass and verify relocalization, navigation, and map-resume, runnable headless in CI
|
||||
- Documented and reliably reproducible by someone else
|
||||
- TBD, expect criteria to evolve
|
||||
|
||||
The maintainer selects among compliant candidates using these criteria. Multiple
|
||||
attempts are welcome and useful even if not selected — modules are swappable, and
|
||||
a non-selected design is still a valid learning exercise and a fallback.

|
||||
|
||||
**Note:** The actual motor used in production Roborock wheels may differ from the
|
||||
catalog entry above. The wheel module includes a **gearbox** (ratio not published)
|
||||
that reduces this to the final wheel RPM. The encoder is mounted after the gearbox.

|
||||
|
||||
### Connector (Wheel Module to Main Board)
|
||||
|
||||
- **Connector type:** J25 (left wheel) / J26 (right wheel) — 16-pin, 1mm pitch SHD (shielded) connector
|
||||
- **Known pins:** 2-4 pins for encoder A/B channels, 2 pins for wheel-drop sensor, remaining for other sensors
|
||||
- **Full pinout:** ❔ **NOT CONFIRMED** — needs PCB tracing or oscilloscope probing
|
||||
|
||||
### Wheel-Drop Sensor
|
||||
|
||||
- **Model:** ❔ **NOT FOUND** — likely a microswitch or Hall-effect sensor within the wheel suspension assembly
|
||||
- **Pinout:** ❔ **NOT CONFIRMED**
|
||||
|
||||

# Procure Part Specs & Datasheets for Sourced Components
|
||||
|
||||
We've already sourced candidate parts (see [BOM.md](../../BOM.md)). To design the I/O
|
||||
board and firmware, *drive the motors and fans*, and build accurate mounts, we need each
|
||||
part's detailed *electrical + mechanical specs* — pinouts, voltages, currents, encoder
|
||||
PPR, torque, waveforms, etc. Vendors rarely publish these for vacuum sub-assemblies, so
|
||||
contributors will *find datasheets, ask vendors, or safely reverse-engineer* them.
|
||||
|
||||
This is the *electrical/mechanical data* companion to
|
||||
[source-3d-models](../source-3d-models) (which covers the *geometry*). No robotics
|
||||
background needed — a multimeter, patience, and (for reverse-engineering) an oscilloscope go far.
|
||||
|
||||
Please check [BOM.md](../../BOM.md) and the [sourcing follow-along blog post](https://makerspet.com/blog/how-to-source-bom-for-oomwoo-open-source-vacuum-robot/)
|
||||
for datasheets/specs already found.
|
||||
|
||||
## What we need, per part
|
||||
|
||||
### Drive wheel assembly (Roborock-family — see BOM)
|
||||
- motor model; motor/assembly *datasheet* (if any)
|
||||
- *encoder type + PPR* (pulses per revolution)
|
||||
- *gearbox ratio*; *wheel diameter*
|
||||
- rated + max motor *voltage*, *current* (no-load & stall), *torque*
|
||||
- max / rated wheel *speed*
|
||||
- *cable length(s)*; *connector models* (both ends); *full connector + motor pinouts*
|
||||
- *wheel-drop sensor* model + pinout (these modules include one)
|
||||
- signal *waveforms* (encoder channels, motor drive)
|
||||
- assembly *weight*
|
||||
|
||||
### Suction fan / blower (several options sourced — see BOM)
|
||||
- fan/motor model; *datasheet*
|
||||
- rated *voltage, current, RPM*; *airflow* + *static pressure (Pa)*
|
||||
- *how to drive it* — BLDC driver + control interface (PWM / tach / hall / 3-phase),
|
||||
soft-start / protection behaviour
|
||||
- *connector model(s) + pinout*; cable length
|
||||
- signal *waveforms*
|
||||
- *weight*
|
||||
|
||||
### Caster / universal wheel assembly (Roomba-family — see BOM)
|
||||
- model, dimensions, mounting, any embedded sensor, weight, datasheet
|
||||
|
||||
## Already found vs still missing
|
||||
|
||||
*Found*
|
||||
- *Fan datasheet (some options):* https://file.elecfans.com/web1/M00/CC/89/o4YBAF-ZOBKAQBvyADDMAglsvTw020.pdf
|
||||
- *Nidec BLDC motors* (candidate fan motors — *bare motors, not the full suction assemblies*):
|
||||
[NCJ-20N Type-3](https://www.nidec.com/en/product/search/category/B101/M102/S100/NCJ-20N-Type-3/),
|
||||
[NCJ-20N Type-4](https://www.nidec.com/en/product/search/category/B101/M102/S100/NCJ-20N-Type-4/)
|
||||
- *Driving the fans:* [ripinteer/fan_protector](https://github.com/ripinteer/fan_protector)
|
||||
— reference for driving / protecting the BLDC blower (from earlier project research)
|
||||
|
||||
*Still missing (help wanted)*
|
||||
- Connector *pinouts* + cable lengths for wheels, fans, caster
|
||||
- *Encoder type + PPR*, gearbox ratios, torque/current under load
|
||||
- *Wheel-drop sensor* model + pinout
|
||||
- Signal *waveforms* (encoder, motor/fan drive)
|
||||
- Suction-*assembly*-level datasheets (we have some bare motors, not the assemblies)
|
||||
- Weights; caster specs
|
||||
|
||||
## Reverse-engineering — only if specs can't be found, and SAFELY
|
||||
|
||||
If a spec isn't published, reverse-engineer it by opening an existing vacuum and probing.
|
||||
*Safety first:*
|
||||
- Don't do it unless you're qualified, experienced.
|
||||
- Opening a vacuum usually *voids the warranty* and *can damage it* — accept that risk knowingly.
|
||||
- *Secure / prop up the vacuum* so it can't scoot off the table or bench when the wheels or
|
||||
fan spin during testing (clamp it, or raise the wheels off the surface).
|
||||
- Respect the *Li-ion battery* — don't short, pierce, or stress the pack; disconnect where sensible.
|
||||
- Mind *pinch points and spinning parts* — keep fingers/hair clear of the impeller and brushes.
|
||||
- Any *mains-connected* testing (e.g. a dock) — extra caution; isolate.
|
||||
- Use a *multimeter + oscilloscope* to capture voltages, currents, and waveforms; trace and
|
||||
*label connector pinouts*; photograph everything.
|
||||
|
||||
*Legal:*
|
||||
- By performing any work for this project including reverse engineering you agree to
|
||||
- wave liability, indemnify this project, the legal entity behind it (Remake AI Statutory Trust) and and its founder
|
||||
- contribute your work and results thereof, if any, as open-source, to be published under Apache 2.0 license
|
||||
|
||||
## Submit
|
||||
|
||||
A PR to `contributions/part-specs/<your-github-username>/<part>/`:
|
||||
- a spec sheet (markdown table) with everything you found
|

- provenance — which vendor / model / revision the data is from
|
||||
- announce it in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=)

# Recovery Behaviors & Safety (ROS2 package)
|
||||
|
||||
Keep the robot *unstuck and safe*. This package provides a *recovery ladder*
|
||||
(back up, wiggle, shake free, rotate, nudge, clear costmap, try an alternate path),
|
||||
*escalation* when a recovery attempt fails, and a final *pause-and-alert* state
|
||||
when everything fails. It also covers *safety*: cliff / wheel-drop / pickup
|
||||
detection, an e-stop, and *status / error reporting* so a human knows what
|
||||
happened. Because the physical robot isn't built yet, this is a *Gazebo
|
||||
simulation*; it is later re-validated on hardware in the
|
||||
[live-robot-bringup RFC](../live-robot-bringup).
|
||||
|
||||
> *Status — ready to start work.* No need to wait for OOMWOO hardware — develop it in the
|
||||
> Gazebo sim ([urdf-gazebo-sim](../urdf-gazebo-sim)) or on the real
|
||||
> [placeholder Proscenic M6 Pro](https://makerspet.com/blog/tutorial-connect-robot-vacuum-cleaner-to-ros-2-proscenic-m6-pro/).

||||

# Request for Contribution - Instructions
|
||||
|
||||
- implement a *recovery ladder*
|
||||
- a configurable, ordered set of behaviors, e.g. *back up*, *wiggle / shake free*, *rotate in place*, *clear the costmap*, *nudge*, *try an alternate path*
|
||||
- pick the right recovery for the situation (wedged, bumper-jammed, no valid path, localization lost)
|
||||
- post in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=) to let everyone know you're working on it, and post your progress
|
||||
- *escalation*
|
||||
- if behavior *N* fails, try *N+1*; track attempts per situation so the robot doesn't repeat a recovery forever
|
||||
- *pause-and-alert*
|
||||
- when the whole ladder is exhausted, stop safely, publish a clear *error / status*, and wait for a human or a resume command — *never thrash*
|
||||
- *safety sensors*
|
||||
- detect *cliffs*, *wheel drop*, *pickup / kidnap* (hand pickup detection to [nav-localize](../nav-localize)), and bumper jams; respond by stopping motors / entering a safe state
|
||||
- *e-stop*
|
||||
- a software emergency stop that brings the robot to a safe state immediately
|
||||
- *status & error reporting*
|
||||
- a structured robot-state / error topic, human-readable, suitable for Home Assistant, so a person knows *why* the robot paused
|
||||
- test it well
|
||||
- induce wedged / stuck situations in sim: trap the robot, drop a dynamic obstacle onto it, place it at a cliff edge, lift it
|
||||
- verify the ladder runs, escalates, then pauses-and-reports; verify it never thrashes indefinitely
|
||||
- regression tests (headless, CI-friendly)
|
||||
- recovery success rate across induced stuck scenarios
|
||||
- guaranteed termination — the robot always reaches *recovered* or *paused-and-reported*, never an infinite loop
|
||||
- safety responses fire on cliff / wheel-drop / pickup / e-stop
|
||||
- submit a PR (pull request) to `contributions/recovery-safety/<your-github-username>/`
|
||||
- link to ROS2 package(s)
|
||||
- instructions, documentation - how to install, run, configure, troubleshoot, test results
|
||||
- videos of recovery, escalation, and pause-and-alert
|
||||
- announce your submission in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=)
|
||||
- iterate with review
|
||||
- TBD, expect the RFC to evolve
|
||||
|
||||
## Acceptance criteria
|
||||
|
||||
Objective, measurable. Examples:
|
||||
- A configurable *recovery ladder* runs the right behaviors for the situation and frees the robot in the large majority of induced stuck scenarios
|
||||
- Recoveries *escalate* and are bounded — the robot never repeats a failed recovery forever
|
||||
- When recovery is impossible, the robot *pauses safely and reports a clear error*, then resumes on command
|
||||
- *Safety*: cliff, wheel-drop, pickup, and e-stop all bring the robot to a safe state
|
||||
- *Status / error reporting* is structured and Home-Assistant-friendly
|
||||
- *Regression tests* pass, including a guaranteed-termination check, runnable headless in CI
|
||||
- Documented and reliably reproducible by someone else
|
||||
- TBD, expect criteria to evolve
|
||||
|
||||
The maintainer selects among compliant candidates using these criteria. Multiple
|
||||
attempts are welcome and useful even if not selected — modules are swappable, and
|
||||
a non-selected design is still a valid learning exercise and a fallback.

# Recovery Safety Prototype by xbattlax
|
||||
|
||||
This contribution provides a first ROS2 recovery-and-safety package for the
|
||||
OOMWOO recovery-safety RFC. It is deliberately small, deterministic, and
|
||||
simulation-first:
|
||||
|
||||
- a bounded recovery ladder for bumper, wedged, no-path, and lost-localization
|
||||
situations
|
||||
- immediate safe stop for e-stop, cliff, wheel-drop, and pickup events
|
||||
- pause-and-alert when the ladder is exhausted
|
||||
- a structured JSON status topic suitable for later Home Assistant integration
|
||||
- unit tests for guaranteed termination and safety responses
|
||||
|
||||
The core ladder lives in pure Python, so it can be regression-tested without a
|
||||
running ROS graph. The ROS2 node is a thin adapter around that core.
|
||||
|
||||

| `/cmd_vel` | `geometry_msgs/msg/Twist` | Short bounded motion commands for recovery. |
|
||||
| `/oomwoo/status` | `std_msgs/msg/String` | JSON status with `state`, `reason_code`, `message`, `recoverable`, `source`, and recovery metadata. |
|
||||
| `/oomwoo/recovery/command` | `std_msgs/msg/String` | JSON command for non-motion actions such as `clear_costmap`. |
|
||||
|
||||
## Build
|
||||
|
||||
From the OOMWOO ROS2 container:
|
||||
|
||||
```bash
|
||||
source /opt/ros/jazzy/setup.bash
|
||||
cd /workspace
|
||||
colcon build \
|
||||
--base-paths contributions/recovery-safety/xbattlax/oomwoo_recovery_safety \
|
||||
--packages-select oomwoo_recovery_safety
|
||||
```
|
||||
|
||||
## Test
|
||||
|
||||
```bash
|
||||
source /opt/ros/jazzy/setup.bash
|
||||
cd /workspace
|
||||
colcon test \
|
||||
--base-paths contributions/recovery-safety/xbattlax/oomwoo_recovery_safety \
|
||||
--packages-select oomwoo_recovery_safety
|
||||
colcon test-result --verbose
|
||||
```
|
||||
|
||||
The tests cover:
|
||||
|
||||
- bounded escalation to pause-and-alert
|
||||
- successful recovery stopping the ladder
|
||||
- e-stop and safety events entering safe pause
|
||||
- ignored duplicate triggers while already recovering
|
||||
- JSON status shape
|
||||
|
||||
## Run
|
||||
|
||||
```bash
|
||||
source /opt/ros/jazzy/setup.bash
|
||||
source install/setup.bash
|
||||
ros2 launch oomwoo_recovery_safety recovery_safety.launch.py
|
||||
```
|
||||
|
||||
Manual trigger example:
|
||||
|
||||
```bash
|
||||
ros2 topic pub --once /oomwoo/recovery/event std_msgs/msg/String "{data: bumper_front}"
|
||||
```
|
||||
|
||||
Mark the current behavior as successful:
|
||||
|
||||
```bash
|
||||
ros2 topic pub --once /oomwoo/recovery/behavior_result std_msgs/msg/String "{data: succeeded}"
|
||||
```
|
||||
|
||||
Trigger e-stop:
|
||||
|
||||
```bash
|
||||
ros2 topic pub --once /oomwoo/safety/e_stop std_msgs/msg/Bool "{data: true}"
|
||||
```
|
||||
|
||||
## Current limitations
|
||||
|
||||
- This is a first integration scaffold, not a full Nav2 behavior-server plugin.
|
||||
- `clear_costmap` is published as an intent on `/oomwoo/recovery/command`; a
|
||||
future adapter should call Nav2 costmap clear services directly.
|
||||
- Success detection is external for now. If no `succeeded` result arrives before
|
||||
a behavior's timeout, the node escalates to the next behavior and eventually
|
||||
pauses.
|
||||
- Cliff, wheel-drop, and pickup are represented as boolean topics until the
|
||||
hardware/simulation message contract is finalized.

# Source 3D Models (STEP) for Off-the-Shelf BOM Parts (procurement)
|
||||
|
||||
To design printed mounts and the chassis that *fit real sourced parts*, we need accurate
|
||||
3D models (*STEP*) of the off-the-shelf components in the [BOM](../../BOM.md) — the
|
||||
drive-wheel assembly, the suction fan/blower (several candidate models), the caster wheel,
|
||||
the side-brush motor, and more. Manufacturers rarely publish these, so the community needs
|
||||
to *obtain, measure, and model* them. Every printed mount and the chassis references this
|
||||
geometry — see [ARCHITECTURE.md](../../docs/ARCHITECTURE.md) §5.2 (mechanical interface
|
||||
standard). Missing models block or force guesswork on the mechanical modules.
|
||||
|
||||
This is a great *first contribution* for anyone with CAD skills and calipers — no
|
||||
robotics or programming needed, and the modules can be modeled *in parallel*.
|
||||
|
||||
## Priority parts (from the [BOM](../../BOM.md))
|
||||
|
||||
Start with the "ready now" mechanical parts:
|
||||
- *Drive wheel assembly pair* (e.g. Roborock S5/S50/S55/S6/S7-family modules)
|
||||
- *Caster / universal wheel* (e.g. Roomba i/j/e/500–900 caster)
|
||||
- *Suction fan / blower* — model the option(s) we shortlist (e.g. Dreame L10s / Nidec /
|
||||
Roborock S8-family blowers listed in the BOM)
|
||||
- *Side-brush motor*, *main-brush assembly*, *water pump*, *battery pack*, etc.
|
||||
|
||||
See [BOM.md](../../BOM.md) for the full list, the exact candidate models, and AliExpress
|
||||
search links, plus [docs/ali_express_research.md](../../docs/ali_express_research.md) for
|
||||
sourcing notes.
|
||||
|
||||
# Request for Contribution - Instructions
|
||||
|
||||
- *Pick a part* from the [BOM](../../BOM.md) and *claim it* in
|
||||
[Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=) or
|
||||
[Discord](https://discord.gg/3y2JKz5T25) so two people don't model the same thing. Post progress too.
|
||||
- *Get an accurate model* — two paths:
|
||||
1. *Find an existing STEP* (manufacturer site, GrabCAD, etc.) and *verify it against the
|
||||
real part* (dimensions match). Fastest — but confirm it's the same model/revision.
|
||||
2. *Model it yourself*: order the exact part (AliExpress links are in the BOM), measure
|
||||
with calipers, optionally use a 3D scanner and build an accurate STEP.
|
||||
- *Capture the interface-relevant geometry* (external only — internal detail is not needed):
|
||||
- Overall *bounding envelope* (so it fits the chassis space / height budget)
|
||||
- *Mounting features*: holes, bosses, clips, bolt pattern — and their exact positions
|
||||
- *Functional interfaces*: axle/shaft position + axis, wheel contact plane, fan air
|
||||
inlet/outlet, connector / wire-exit locations
|
||||
- *Mating faces* where other modules attach
|
||||
- Note the *key overall dimensions*
|
||||
- *Record provenance* — the exact vendor + link + which model/revision you measured. Parts
|
||||
vary between sellers and revisions; say which one this model represents.
|
||||
- *Submit a PR* to `contributions/source-3d-models/<your-github-username>/<part-name>/`:
|
||||
- the *STEP* file (primary deliverable) + native CAD source (Fusion/SolidWorks/etc.) if you modeled it
|
||||
- a *photo* of the real part (ideally next to your model / with calipers)
|
||||
- the *source link* (AliExpress/vendor) and *key dimensions*
|
||||
- notes on tolerances and how you measured
|
||||
- announce it in [Project Discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=)
|
||||
- Iterate with review.
|
||||
- TBD, expect the RFC to evolve.
|
||||
|
||||
(*) If you have a strong reason to model a different variant than the BOM lists, post your
|
||||
rationale in [discussions](https://github.com/makerspet/oomwoo/discussions?discussions_q=) first.
|
||||
|
||||
## Acceptance criteria
|
||||
|
||||
Objective, measurable. Examples:
|
||||
- Accurate *STEP* of the specified part — bounding envelope, mounting features, and
|
||||
functional interfaces match the measured real part (within a stated tolerance)
|
||||
- Includes the *exact source link*, *key dimensions*, and a *photo* of the real part
|
||||
- Please make sure the model is licensed as open-source
|
||||
- *Verifiable/reproducible* by someone else who buys the same part
|
||||
- STEP provided (+ native CAD source if self-modeled)
|
||||
- Documented well enough that a mount designer can build against it with confidence
|
||||
- TBD, expect criteria to evolve
|
||||
|
||||
The maintainer selects among compliant candidates using these criteria. Multiple attempts
|
||||
are welcome and useful even if not selected — models are swappable, and a non-selected
|
||||
model is still a valid reference and a fallback.

The vacuum fan assembly provides air suction to the main brush and streams air into the dust bin.

# OOMWOO Architecture Brief
|
||||
|
||||
> *Status: DRAFT / skeleton.* This document defines the system so that modules
|
||||
> can be built in parallel without colliding. Sections marked *TBD* are the
|
||||
> gating decisions; until they are filled in, hardware modules that must fit
|
||||
> together cannot be finalized. Treat the interface specs as the contract every
|
||||
> module agrees to.
|
||||
|
||||
## 1. Purpose/Goal and scope
|
||||
|
||||
OOMWOO is an open-source, 3D-printed, ROS2-based home robot vacuum with 2D LiDAR
|
||||
and Home Assistant support. It is designed to be *built from scratch by
|
||||
the community*, module by module, clean well and to double as an affordable ROS2
|
||||
development and learning platform.
|
||||
|
||||
*North star (not MVP):* OOMWOO is also the reference hardware for a broader
|
||||
robot application platform. Architectural boundaries (especially the app layer in
|
||||
§6) are drawn with that future in mind, but the MVP below deliberately excludes it.
|
||||
|
||||
## 2. Design principles
|
||||
|
||||
- *Open and swappable.* Every module has a defined interface. Any compliant
|
||||
implementation can replace another. No module depends on the internals of
|
||||
another, only on its published interface.
|
||||
- *Simulation-first.* Software must run in Gazebo before it runs on hardware,
|
||||
so contributors with no robot can still build and test.
|
||||
- *Affordable and printable.* Target off-the-shelf parts (a CM4/CM5-class compute
|
||||
module, common vacuum LiDARs, sourced Roborock/Dreame/Xiaomi motors and wear
|
||||
parts) and FDM-printable chassis parts.
|
||||
- *Safety is reviewed, not crowd-trusted.* Battery, charging, and motor-driver
|
||||
modules pass a maintainer safety review before merge (see §8).
|
||||
- *Reference-design backed.* A known-working vacuum (see the references in the
|
||||
[README](../README.md)) anchors the geometry and proves feasibility.
|
||||
|
||||

> Interfaces are largely decided (see §5); refine as the io-pcb spec settles.
|
||||
|
||||
## 4. Coordinate frames and conventions
|
||||
|
||||
- *TBD:* Define `base_link` origin and orientation (REP-103: x-forward,
|
||||
y-left, z-up). All mechanical mounting points and URDF frames reference this.
|
||||
- *TBD:* Define the reference plane (floor contact), robot diameter, and height
|
||||
envelope. *These two numbers gate every hardware module.* Source these from the *sourced
|
||||
parts* + a 3D-scanned donor (see [source-3d-models](../contributions/source-3d-models));
|
||||
the current baseline is a ~349 mm round body ([oomwoo-one URDF](https://github.com/makerspet/oomwoo-one)).
|
||||
- Units: millimeters, kilograms, SI. Right-handed frames. Angles in radians.
|
||||
|
||||
## 5. Hardware architecture
|
||||
|
||||
### 5.1 Chassis and reference frame
|
||||
The chassis is the *integration backbone*. It publishes the mounting interface
|
||||
every other hardware module targets. Reference geometry (dimensions, wheelbase,
|
||||
motor specs, mass) comes from the *sourced parts* ([BOM](../BOM.md)) + 3D scans of
|
||||
a donor vacuum (see [source-3d-models](../contributions/source-3d-models)); the
|
||||
[oomwoo-one URDF](https://github.com/makerspet/oomwoo-one) carries the current
|
||||
~349 mm round-body baseline.
|
||||
|
||||
- *TBD:* Overall diameter and height budget.
|
||||
- *TBD:* Mounting grid / bolt pattern standard (e.g., M3 on a defined pitch).
|
||||
- *TBD:* Mass budget per module and total target mass.
|
||||
|
||||
### 5.2 Mechanical interface standard (the contract)
|
||||
Every hardware module's RFC must specify, against this standard:
|
||||
- Mounting points (bolt pattern, location relative to `base_link`).
|
||||
- Bounding envelope (max size the module may occupy).
|
||||
- Mass budget.
|
||||
- Mating tolerances and print orientation.
|
||||
- *TBD:* Define the standard connector/fastener set (screw sizes, heat-set
|
||||
inserts, etc.) so parts from different authors actually mate.
|
||||
|
||||
### 5.3 Electrical interface standard (the contract)
|
||||
- *Battery:* off-the-shelf pack with a *built-in BMS* — *4S2P Li-ion*, ~14.4 V
|
||||
nominal, ~5200 mAh / ~75 Wh (OEM BRR-2P4S-5200 class), charged 16.8 V CC/CV with
|
||||
NTC temperature sense. Chemistry is now decided; see the [BOM](../BOM.md).
|
||||
- *TBD:* Power rails distributed to modules (VBAT, 5V, 3.3V) and connector types/pinouts.
|
||||
- *CPU ↔ MCU:* a *custom high-speed serial protocol* (not micro-ROS) carries
|
||||
commands/telemetry, plus discrete GPIOs (CPU power on/off, and a CPU-reset line
|
||||
the MCU asserts on missed health packets). The *MCU owns motors and sensors*; the
|
||||
CPU never drives them directly.
|
||||
- *Sensors:* bumper/cliff/wheel-drop and analog IR are *MCU-side* (digital in / ADC);
|
||||
the *LiDAR (UART, ~5 Hz)*, MIPI camera(s), IMU, and serial audio attach to the *CPU*.
|
||||
|
||||
### 5.4 Compute (CPU) and real-time controller (MCU)
|
||||
|
||||
OOMWOO splits compute across two processors — mirroring how consumer vacuums are
|
||||
built, and, crucially, so that *safety never depends on Linux/ROS2*.
|
||||
|
||||
*CPU (compute module).* The I/O board is a *carrier* that accepts a *Raspberry Pi
|
||||
Compute Module 4 or 5* and — because the CM4 pinout is a de-facto standard — the
|
||||
many *pin-compatible alternative modules* (Radxa CM3/CM4, Pine64 SOQuartz, LuckFox
|
||||
Core3566, …), several with an *NPU* for future on-device vision. The CPU runs
|
||||
*ROS2, SLAM (slam_toolbox), Nav2, LiDAR processing, and high-level behavior*. CM
|
||||
modules are low-profile (helps the height budget) and swappable (hackable, cheaper,
|
||||
NPU options).
|
||||
- *Minimum target: a 4 GB CM4/CM5 (or Pi 4).* Realistic prior art runs
|
||||
slam_toolbox + Nav2 onboard a 4 GB Pi 4. Getting the floor to *2 GB* is a goal
|
||||
(ROS2 composable nodes; selectively rewriting heavy Python nodes in Rust/C++) —
|
||||
*no guarantee*, to be settled by the compute-benchmark. No 8–16 GB module needed.
|
||||
- *Cooling:* no dedicated CPU fan — the suction fan's airflow cools the compute
|
||||
board, as in consumer vacuums.
|
||||
- The earlier bespoke *RK3562* reference schematic is *dropped* in favour of the
|
||||
CM4/CM5 carrier.
|
||||
|
||||
*MCU (real-time / safety controller).* A dedicated microcontroller — *tentatively
|
||||
the STM32G070RBT6* (~56 GPIO incl. 16 ADC channels, ~$1 at JLCPCB, LQFP not BGA) —
|
||||
owns *motors, encoders, all sensors, battery-charging control, and safety*. Its
|
||||
role is *fixed*: functionality does not migrate onto the CPU, and CPU work does not
|
||||
migrate onto the MCU.
|
||||
- Firmware is *tentatively FreeRTOS* (static allocation, watchdog, guaranteed
|
||||
reaction times, CE-oriented) speaking a *custom serial protocol — not micro-ROS*
|
||||
(the tried-and-true consumer-vacuum approach; cf. the reverse-engineered
|
||||
[3irobotix protocol](https://github.com/codetiger/VacuumRobot)).
|
||||
- *Hard safety lives here, independent of Linux/ROS2:* the MCU stops all motors on
|
||||
a *bumper hit, cliff detection, or wheel-drop*, current-limits a *stuck brush*,
|
||||
and *watchdogs the CPU* — if the CPU's health packets stop, it stops the motors
|
||||
and can *reset the CPU*.
|
||||
- Tentative ~60-signal pin budget: see the [io-pcb RFC](../contributions/io-pcb)
|
||||
appendix (why the MCU needs a high-GPIO part).
|
||||
|
||||
*CPU ↔ MCU link.* A *high-speed serial* channel carries commands/telemetry both
|
||||
ways, plus discrete GPIOs — notably the *CPU-reset* line the MCU asserts on missed
|
||||
health packets, and CPU power on/off. Any LiDAR supported by `kaiaai/LDS` /
|
||||
`lds2d` is interface-compatible.
|
||||
|
||||
### 5.5 Two build profiles
|
||||
|
||||
The same carrier I/O board + MCU supports two swappable compute configurations:
|
||||
|
||||
| | *Consumer / regular* | *Educational / lower-cost* |
|
||||
|---|---|---|
|
||||
| CPU-slot module | CM4 / CM5 (or pin-compatible alt) | *ESP32-S3* board in the CM4 form factor |
|
||||
| Where ROS2 / SLAM runs | *onboard* (ROS2 + slam_toolbox + Nav2) | *offboard* on a local dev PC; ESP32-S3 runs *micro-ROS* |
|
||||
| Link | self-contained robot | robot ↔ dev PC over *Wi-Fi* |
|
||||
| Trade-off | plug-and-play for non-experts | cheaper, but Wi-Fi congestion / dead-zones — a learning platform, not a polished consumer product |
|
||||
|
||||
Onboard SLAM is the default for the consumer version *so non-experts can build and
|
||||
use it* without setting up a separate ROS2 dev machine. The ESP32-S3 can only be
|
||||
the *CPU-slot* option — it lacks the ~60 GPIO the MCU role needs, so it never
|
||||
replaces the STM32.
|
||||
|
||||
## 6. Software architecture
|
||||
|
||||
### 6.1 ROS2 graph (MVP)
|
||||
- Core nodes (MVP): LiDAR driver, base controller (diff-drive), odometry,
|
||||
teleop, SLAM (manual mapping), TF/URDF publisher.
|
||||
- *Interface contract:* each software module's RFC declares the ROS2 topics,
|
||||
services, message types, and parameters it publishes/consumes. Modules depend
|
||||
on these interfaces, not on each other's code. See
|
||||
[SOFTWARE_INTERFACES.md](SOFTWARE_INTERFACES.md) for the current draft ROS2
|
||||
graph contract.
|
||||
|
||||

|
||||
- Gazebo + URDF, with a set of residential-layout worlds for navigation and
|
||||
coverage testing. Sim parity is a first-class requirement, not an afterthought.
|
||||
|
||||
### 6.3 Application layer (Phase 2 — north star, NOT in MVP)
|
||||
A ROS2-agnostic layer that runs third-party apps locally in isolated *Podman*
|
||||
containers, so app developers need no ROS2 expertise. Documented here only to
|
||||
keep its boundary clean; *explicitly out of scope for the Aug 31 MVP.*
|
||||
|
||||
## 7. MVP definition (target: 2026-08-31)
|
||||
|
||||
*In scope:* ROS2 on a CM4/CM5-class compute module · LiDAR · manual SLAM/mapping · teleop drive ·
|
||||
3D-printed chassis · Gazebo sim with URDF · evaluation + demo video. No dock,
|
||||
no autonomous exploration, no Home Assistant, no app layer.
|
||||
|
||||
*Explicit non-goals for MVP:* autonomous coverage, docking, auto-empty, mopping,
|
||||
Home Assistant, the app platform, accessories. These are later phases.
|
||||
|
||||
*Critical-path ownership:* the maintainer (+ small core) own the chassis,
|
||||
interface specs, and integration so the MVP does not depend on volunteer delivery
|
||||
timing. Community modules accelerate and improve the MVP; they do not block it.
|
||||
|
||||
## 8. Safety review gate
|
||||
|
||||
Battery, charging, motor-driver, and mains-adjacent modules require maintainer
|
||||
safety review before merge. RFCs for these modules must include a hazard note
|
||||
(over-current, thermal, short, mechanical pinch).
|
||||
|
||||
The battery risk is *reduced* by using an *off-the-shelf 4S2P Li-ion pack with a
|
||||
built-in BMS* (over-charge / over-discharge / short protection); the review then
|
||||
focuses on the *16.8 V CC/CV charging path + NTC temperature sense*. *Hard safety
|
||||
lives on the MCU, never on Linux/ROS2* — it independently stops motors on
|
||||
bumper/cliff/wheel-drop, current-limits a stuck brush, and watchdog-resets the CPU.
|
||||
|
||||
## 9. Roadmap (phases after MVP)
|
||||
|
||||
1. Rechargeable battery + basic dock + autonomous floor mapping.
|
||||
2. Home Assistant integration.
|
||||
3. Application layer (Podman app runtime) + first delightful apps.
|
||||
4. Accessories and novel apps; integrations (e.g., LeRobot arm).
|
||||
|
||||
## 10. Open questions
|
||||
|
||||
- *Resolved:* the MCU runs a *custom serial protocol (not micro-ROS)*; the CPU runs
|
||||
*onboard ROS2/SLAM/Nav2*. micro-ROS is used only in the *educational* ESP32-S3
|
||||
profile (SLAM offboard on a dev PC). See §5.4–5.5.
|
||||
- *Resolved:* battery is an off-the-shelf *4S2P Li-ion pack with a built-in BMS*,
|
||||
charged 16.8 V CC/CV. See §5.3, §8.
|
||||
- Can OOMWOO's onboard ROS2 stack fit in *2 GB* (composable nodes, selective Rust)
|
||||
rather than 4 GB? To be answered by the compute-benchmark.
|
||||
- MCU family: *STM32G070RBT6* is the tentative pick (GPIO/ADC count, ~$1 at JLCPCB,
|
||||
LQFP) — open to alternatives.
|
||||
- One hardware-agnostic HAL covering reference vacuum + DIY builds (community idea)?
|
||||
- Module selection process: who decides which competing implementation wins, and
|
||||
on what criteria? (See each module's acceptance criteria.)

# Contributing to OOMWOO
|
||||
|
||||
Thanks for your interest. OOMWOO is an open-source robot vacuum you build
|
||||
yourself, and it's at a very early stage. That's the best time to get involved,
|
||||
the foundations are still being laid and your input can shape the direction.
|
||||
|
||||
The project is built *module by module* so many people can work in parallel.
|
||||
Browse the [module list in the README](../README.md#requests-for-contributions),
|
||||
and see [ARCHITECTURE.md](ARCHITECTURE.md) for how the pieces fit together.
|
||||
|
||||
## Ways to help right now
|
||||
|
||||
You don't need to be a roboticist to contribute:
|
||||
|
||||
- *Ideas and feedback* — open a [Discussion](https://github.com/makerspet/oomwoo/discussions)
|
||||
about features, design choices, or what would make you build one.
|
||||
- *Code* — firmware, ROS2 packages, Home Assistant integration.
|
||||
- *Hardware* — 3D-printable chassis design, mechanical parts, PCB.
|
||||
- *Documentation* — build guides, wiring diagrams, troubleshooting notes.
|
||||
- *Testing* — once there's something to build, real-world build reports are gold.
|
||||
- *Spread the word* — star the repo, share your build, post a demo.
|
||||
|
||||
## Getting started
|
||||
|
||||
1. *Pick a module.* Browse the
|
||||
[module list in the README](../README.md#requests-for-contributions) and choose a
|
||||
hardware or software module. Software and simulation modules can start
|
||||
immediately; hardware modules wait on the interface specs in
|
||||
[ARCHITECTURE.md](ARCHITECTURE.md). Read the module's `README.md` so you know
|
||||
the contract.
|
||||
2. *Start a conversation first.* Claim or ask about the module in its
|
||||
[Issue](https://github.com/makerspet/oomwoo/issues) or
|
||||
[Discussion](https://github.com/makerspet/oomwoo/discussions) before writing
|
||||
code, so we align on the approach and avoid wasted effort.
|
||||
3. *Build it in your own repo.* For code and simulation modules, develop your
|
||||
package in your **own public repository** — you own it, version it, and keep the
|
||||
credit. Build against the ROS2 interface contract in
|
||||
[SOFTWARE_INTERFACES.md](SOFTWARE_INTERFACES.md) so your work stays interoperable
|
||||
with other modules. (Docs and small reference material are handled differently —
|
||||
see below.)
|
||||
4. *Submit a pointer PR.* Add a link to your repo in the module's entry with a
|
||||
one-line description. It's small, easy to review, and lets several
|
||||
implementations of the same module sit side by side. Keep the PR focused.
|
||||
5. *Iterate in the open.* Modules are swappable — the best implementation surfaces
|
||||
over time, with the maintainer having the last call. A design that isn't
|
||||
selected is still a useful fallback.
|
||||
|
||||
## How contributions are structured
|
||||
|
||||
OOMWOO keeps the core small and lets the community grow around it:
|
||||
|
||||
- *Canonical / reference code stays first-party.* [oomwoo-one](https://github.com/makerspet/oomwoo-one)
|
||||
(robot description + sim), [oomwoo-install](https://github.com/makerspet/oomwoo-install)
|
||||
(dev environment), and the `kaiaai_*` packages are maintained by the project so the
|
||||
out-of-the-box build always works.
|
||||
- *Module implementations (code) live in your repo.* You build a competing
|
||||
implementation of a module — a sim, a navigation stack, a behavior — in your own
|
||||
repository and submit a *link*. The project features accepted work from the
|
||||
module's page, credited to you. When a contribution is *featured*, we pin a
|
||||
specific commit or tag (and may fork it into the makerspet org) so the reference
|
||||
build stays reproducible even if the upstream repo moves.
|
||||
- *Docs, specs and small reference material stay in-tree.* Part specifications,
|
||||
datasheets, STEP-model sourcing notes, PCB notes, and benchmarks are lightweight
|
||||
and best kept alongside the project — contribute those under
|
||||
`contributions/<module>/<your-username>/` as files in a PR.
|
||||
|
||||
Why links for code? You keep ownership, credit, and freedom to iterate; the project
|
||||
stays lean and avoids absorbing third-party code and its licensing; and multiple
|
||||
implementations of a module can coexist and be compared. The shared
|
||||
[SOFTWARE_INTERFACES.md](SOFTWARE_INTERFACES.md) contract is what keeps
|
||||
independently-built modules compatible.
|
||||
|
||||
## Hardware contributions
|
||||
|
||||
For CAD and mechanical work, please include source files (not just exported STLs)
|
||||
where possible, so others can modify your design. Note the tool and version you
|
||||
used. If your change affects the bill of materials, mention it in the PR. Each
|
||||
hardware module must stay within the mechanical/electrical interfaces in
|
||||
[ARCHITECTURE.md](ARCHITECTURE.md).
|
||||
|
||||
*Safety:* battery, charging, motor-driver, and mains-adjacent modules require a
|
||||
maintainer safety review before merge. Include a hazard note in your submission.
|
||||
|
||||
## Code style
|
||||
|
||||
Conventions are still being established. For now: keep it simple, readable, and
|
||||
consistent with the surrounding code. ROS2 packages should follow standard ROS2
|
||||
layout and naming. We'll formalize linting and style as the codebase grows.
|
||||
|
||||
## Licensing
|
||||
|
||||
By contributing, you agree that your contributions are licensed under the
|
||||
project's [Apache License 2.0](../LICENSE). Hardware design files will be released
|
||||
under an open hardware license (to be finalized); contributions of hardware
|
||||
files are made on that same open basis.
|
||||
|
||||
## Community and conduct
|
||||
|
||||
Be respectful, helpful, and welcoming. We want OOMWOO to be an easy, friendly
|
||||
place for makers of every skill level. Harassment or hostility isn't tolerated.

# RFC Backlog (planned / not-yet-active)
|
||||
|
||||
Planned modules that are *not yet active RFCs*. The RFCs ready to work on *now* live in the
|
||||
[README status table](../README.md#requests-for-contributions), and each active RFC's full
|
||||
spec is under [contributions/](../contributions). An item here graduates into an active RFC
|

(its own `contributions/<module>/` folder) once it is unblocked and ready.
|

|
||||
## On hold (have an RFC, paused pending sourced parts + a 3D reference design)

|
||||
| Module | RFC | Notes |
|
||||
|---|---|---|
|

# OOMWOO ROS2 Software Interfaces
|
||||
|
||||
> Status: DRAFT. This is the shared software contract for simulation-first
|
||||
> contributions. It reflects the current `urdf-gazebo-sim` package and should be
|
||||
> updated whenever a module needs a new public topic, service, action, frame, or
|
||||
> parameter.
|
||||
|
||||
## Purpose
|
||||
|
||||
OOMWOO software modules are meant to be swappable. A contributor should be able
|
||||
to build `clean-and-map`, `nav-localize`, `recovery-safety`, `dock-cycle`, or
|
||||
`cleaning-jobs` without depending on another module's private implementation.
|
||||
|
||||
This document defines the public ROS2 surface area those modules can share while
|
||||
the hardware is still evolving. It is not a final hardware API.
|
||||
|
||||
## Naming rules
|
||||
|
||||
- Public names below are shown as root topics, for example `/scan`. Launch files
|
||||
and node configs may use relative names such as `scan` when they resolve to
|
||||
the same root topic in the default launch.
|
||||
- Use REP-103 frames and SI units.
|
||||
- Prefer standard ROS2/Nav2 message types before adding custom OOMWOO messages.
|
||||
- If a module introduces a new public interface, document the producer, consumer,
|
||||
message type, QoS expectation, and failure behavior in its README and update
|
||||
this file.
|
||||
- Simulation-only details, such as Gazebo collision entity names, must not leak
|
||||
into cross-module contracts unless they are explicitly marked as simulation
|
||||
diagnostics.
|
||||
|
||||
## Frames
|
||||
|
||||
| Frame | Owner | Meaning |
|
||||
|---|---|---|
|
||||
| `map` | SLAM/localization | Global map frame used by SLAM, AMCL, Nav2, and saved maps. |
|
||||
| `odom` | Base odometry | Locally continuous odometry frame. |
|
||||
| `base_footprint` | Robot description / odometry | Planar base frame for navigation. |
|
||||
| `base_link` | Robot description | Main robot body frame. Hardware modules should reference this once geometry is frozen. |
|
||||
| `base_scan` | Robot description | 2D LiDAR frame. |
|
||||
|
||||
Open decision: `base_link` origin, reference plane, robot diameter, and height
|
||||
envelope are still defined in `ARCHITECTURE.md`.
|
||||
|
||||
## Baseline Topics
|
||||
|
||||
These topics are provided by the current Gazebo simulation or standard Nav2/SLAM
|
||||
bringup and should be treated as the MVP baseline.
|
||||
|
||||
| Topic | Type | Direction | Producer | Consumers |
|
||||
|---|---|---|---|---|
|
||||
| `/cmd_vel` | `geometry_msgs/msg/Twist` | Command | Teleop, Nav2 velocity smoother, recovery nodes | Gazebo diff-drive / base controller |
|
||||
| `/odom` | `nav_msgs/msg/Odometry` | State | Gazebo odometry / base controller | SLAM, AMCL, Nav2, recovery and job logic |
|
||||
| `/tf` | `tf2_msgs/msg/TFMessage` | State | Robot state publisher, odometry, SLAM/localization | All pose-aware modules |
|
||||
| `/joint_states` | `sensor_msgs/msg/JointState` | State | Gazebo joint state publisher / hardware base | Robot state publisher, diagnostics |
|
||||
| `/scan` | `sensor_msgs/msg/LaserScan` | Sensor | 2D LiDAR / Gazebo LiDAR | SLAM, AMCL, Nav2 costmaps, wall following |
|
||||
| `/map` | `nav_msgs/msg/OccupancyGrid` | State | SLAM or map server | Nav2, cleaning, zones, visualization |
|
||||
| `/bumper_left` | `ros_gz_interfaces/msg/Contacts` in Gazebo | Sensor | Gazebo left contact sensor | Recovery, safety, clean-and-map obstacle handling |
|
||||
| `/bumper_right` | `ros_gz_interfaces/msg/Contacts` in Gazebo | Sensor | Gazebo right contact sensor | Recovery, safety, clean-and-map obstacle handling |
|
||||
|
||||
### Bumper events
|
||||
|
||||
The current simulation publishes raw Gazebo contact messages:
|
||||
|
||||
- Message type: `ros_gz_interfaces/msg/Contacts`
|
||||
- Contact list field: `contacts`
|
||||
- Per-contact fields: `collision1`, `collision2`, `positions`, `normals`,
|
||||
`depths`, `wrenches`
|
||||
|
||||
Consumers should treat `len(msg.contacts) > 0` as a bumper event after filtering
|
||||
out ground-plane contacts. Do not read a `collisions` field; that belongs to the
|
||||
single-contact message type and is not what the bridge publishes.
|
||||
|
||||
Hardware may eventually replace raw Gazebo contacts with a normalized bumper
|
||||
message. Until that decision is made, module submissions should isolate the
|
||||
Gazebo-specific parsing behind a small adapter.
|
||||
|
||||
## Nav2 Interfaces
|
||||
|
||||
Modules should reuse Nav2 actions and servers where possible.
|
||||
|
||||
| Interface | Type | Typical consumer |
|
||||
|---|---|---|
|
||||
| `/navigate_to_pose` | `nav2_msgs/action/NavigateToPose` | `nav-localize`, `cleaning-jobs`, `dock-cycle` |
|
||||
| `/navigate_through_poses` | `nav2_msgs/action/NavigateThroughPoses` | Coverage, room jobs, dock approach |
|
||||
| Nav2 behavior server | `spin`, `backup`, `drive_on_heading`, `wait` behaviors | Recovery and local fallback logic |
|
||||
| Costmaps | Nav2 local/global costmap topics | Obstacle handling, zones, diagnostics |
|
||||
| Map saver | Nav2 map saver service/CLI | `clean-and-map`, `nav-localize` |
|
||||
|
||||
If a module needs to command motion directly, it must define how it arbitrates
|
||||
with Nav2 and recovery nodes so two nodes do not fight over `/cmd_vel`.
|
||||
|
||||
## Module Contracts
|
||||
|
||||
| Module | Inputs | Outputs / public behavior |
|
||||
|---|---|---|
|
||||
| `urdf-gazebo-sim` | `/cmd_vel` | Publishes `/scan`, `/odom`, `/tf`, `/joint_states`, `/bumper_left`, `/bumper_right`; provides worlds and robot description. |
|
||||
| `clean-and-map` | `/scan`, `/odom`, `/tf`, bumper events, optional Nav2 actions | Drives first-pass coverage, produces a complete map, defines a done condition, saves map artifacts. |
|
||||
| `nav-localize` | Saved map, `/scan`, `/odom`, `/tf`, Nav2 bringup | Provides known-map navigation, relocalization, and map-resume behavior. |
|
||||
| `recovery-safety` | Bumper events, future cliff/wheel-drop/pickup/e-stop signals, Nav2 failures | Stops or gates motion, runs bounded recoveries, publishes clear pause/error status. |
|
||||
| `floor-care` | `/scan`, map/coverage context, future surface sensor | Provides wall/edge following, surface classification, and mop actuator decisions. |
|
||||
| `cleaning-jobs` | Saved map, zones, coverage progress, battery/bin/mop status, Nav2 actions | Provides start/pause/resume/cancel/status job behavior suitable for a future Home Assistant layer. |
|
||||
| `dock-cycle` | Nav2/localization, dock marker, battery/service state | Provides undock, return-to-dock, precise docking, recharge/service completion, and find-dock fallback. |
|
||||
| `live-robot-bringup` | Hardware drivers, same logical topics | Validates that hardware exposes the same public interfaces as the simulation. |
|
||||
|
||||
## Status and Errors
|
||||
|
||||
The final robot status API is still open. Until it is selected, modules that
|
||||
need status reporting should document:
|
||||
|
||||
- `state`: short machine-readable state, for example `cleaning`, `recovering`,
|
||||
`paused`, `docked`, or `error`
|
||||
- `reason_code`: stable machine-readable reason, for example `BUMPER_STUCK`,
|
||||
`LOCALIZATION_LOST`, or `LOW_BATTERY`
|
||||
- `message`: human-readable explanation
|
||||
- `recoverable`: whether a resume command is expected to work
|
||||
- `source`: module name that produced the status
|
||||
|
||||
Open decision: choose the transport and type for cross-module status, likely a
|
||||
standard diagnostic message or a small OOMWOO-specific message package.
|
||||
|
||||
## QoS and Parameters
|
||||
|
||||
- `use_sim_time` should be true in simulation launch files.
|
||||
- Sensor streams such as `/scan` should use sensor-data QoS where configurable.
|
||||
- `/map` and saved-map metadata should be available to late joiners where the
|
||||
producer supports transient-local durability.
|
||||
- Command topics should use small queues and should fail safe: stale commands
|
||||
must not keep the robot moving.
|
||||
|
||||
## Validation Checklist
|
||||
|
||||
A module submission that depends on the MVP simulation should document how to
|
||||
check the interfaces it uses. At minimum:
|
||||
|
||||
```bash
|
||||
ros2 topic list
|
||||
ros2 topic echo /scan --once
|
||||
ros2 topic echo /odom --once
|
||||
ros2 topic echo /bumper_left
|
||||
ros2 topic echo /bumper_right
|
||||
ros2 run tf2_tools view_frames
|
||||
```
|
||||
|
||||
For Nav2-based modules, also document how to send a `NavigateToPose` goal and
|
||||
how to confirm `/cmd_vel` arbitration is safe.
|
||||
|
||||
## Miscellaneous
|
||||
|
||||
- PR your packages into the official distribution [makerspet/oomwoo-install](https://github.com/makerspet/oomwoo-install)

# Write Your First OOMWOO ROS 2 Package: Cover the Floor While Mapping
|
||||
|
||||
> *Draft for makerspet.com (WordPress / Gutenberg).* Post 2 of 2. Builds on Post 1
|
||||
> (*Simulate the oomwoo-one Robot Vacuum in Gazebo with ROS 2*). Here you'll write a small
|
||||
> *pure-ROS 2* package that drives `oomwoo-one` on a coverage path *while* SLAM maps the
|
||||
> room, and launch it all with one `ros2 launch`.
|
||||
|
||||
This is the "hello world" of developing for OOMWOO. It's deliberately simple — a reactive
|
||||
"drive forward, turn when blocked" coverage that, combined with SLAM, maps and roughly covers
|
||||
a room. Proper boustrophedon coverage is the [clean-and-map
|
||||
RFC](https://github.com/makerspet/oomwoo/tree/main/contributions/clean-and-map); this teaches
|
||||
you the mechanics of writing and launching an OOMWOO node.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
The dev environment from *Post 1* (the `makerspet/oomwoo:jazzy-dev` container running, with
|
||||
`kaia config robot.model oomwoo_one` set). Everything below runs *inside the container*.
|
||||
|
||||
## 1. Create a ROS 2 package
|
||||
|
||||
```
|
||||
mkdir -p ~/ros2_ws/src && cd ~/ros2_ws/src
|
||||
ros2 pkg create --build-type ament_python oomwoo_coverage --dependencies rclpy sensor_msgs geometry_msgs
|
||||
```
|
||||
|
||||
## 2. Write the coverage node
|
||||
|
||||
Create `~/ros2_ws/src/oomwoo_coverage/oomwoo_coverage/coverage_node.py`:
|
||||
|
||||
```python
|
||||
import math
|
||||
import rclpy
|
||||
from rclpy.node import Node
|
||||
from sensor_msgs.msg import LaserScan
|
||||
from geometry_msgs.msg import Twist
|
||||
|
||||
|
||||
class Coverage(Node):
|
||||
"""Drive forward; when the path ahead is blocked, turn until it clears.
|
||||
Combined with SLAM, this bounces around a room and maps it."""
|
||||
|
||||
def __init__(self):
|
||||
super().__init__('coverage')
|
||||
self.pub = self.create_publisher(Twist, 'cmd_vel', 10)
|
||||
self.create_subscription(LaserScan, 'scan', self.on_scan, 10)
|
||||
self.clear = True
|
||||
self.turn_dir = 1.0
|
||||
self.create_timer(0.1, self.tick) # 10 Hz control loop
|
||||
|
||||
def on_scan(self, msg):
|
||||
n = len(msg.ranges)
|
||||
if n == 0:
|
||||
return
|
||||
# Check the forward +/- 25 deg sector (forward = scan index 0 for this LiDAR;
|
||||
# adjust 'center' if your scan's zero points elsewhere).
|
||||
sector = int(math.radians(25) / msg.angle_increment)
|
||||
idxs = [(i) % n for i in range(-sector, sector + 1)]
|
||||
fwd = [msg.ranges[i] for i in idxs
|
||||
if msg.range_min < msg.ranges[i] < msg.range_max]
|
||||
was_clear = self.clear
|
||||
self.clear = (min(fwd) > 0.35) if fwd else True
|
||||
if was_clear and not self.clear:
|
||||
self.turn_dir *= -1.0 # alternate turn direction each time we hit something
|
||||
|
||||
def tick(self):
|
||||
cmd = Twist()
|
||||
if self.clear:
|
||||
cmd.linear.x = 0.20 # m/s forward
|
||||
else:
|
||||
cmd.angular.z = 0.8 * self.turn_dir # rad/s turn until clear
|
||||
self.pub.publish(cmd)
|
||||
|
||||
|
||||
def main():
|
||||
rclpy.init()
|
||||
node = Coverage()
|
||||
try:
|
||||
rclpy.spin(node)
|
||||
except KeyboardInterrupt:
|
||||
pass
|
||||
node.destroy_node()
|
||||
rclpy.shutdown()
|
||||
|
||||
|
||||
if __name__ == '__main__':
|
||||
main()
|
||||
```
|
||||
|
||||
## 3. Register the node
|
||||
|
||||
In `~/ros2_ws/src/oomwoo_coverage/setup.py`, add the console script:
|
||||
|
||||
```python
|
||||
entry_points={
|
||||
'console_scripts': [
|
||||
'coverage = oomwoo_coverage.coverage_node:main',
|
||||
],
|
||||
},
|
||||
```
|
||||
|
||||
## 4. Add a launch file (sim + SLAM + your node, in one command)
|
||||
|
||||
Create `~/ros2_ws/src/oomwoo_coverage/launch/coverage.launch.py`:
|
||||
|
||||
```python
|
||||
import os
|
||||
from launch import LaunchDescription
|
||||
from launch.actions import IncludeLaunchDescription, TimerAction
|
||||
from launch.launch_description_sources import PythonLaunchDescriptionSource
|
||||
from launch_ros.actions import Node
|
||||
from ament_index_python.packages import get_package_share_directory
|
||||
|
||||
|
||||
def generate_launch_description():
|
||||
gazebo = IncludeLaunchDescription(PythonLaunchDescriptionSource(
|
||||
os.path.join(get_package_share_directory('kaiaai_gazebo'),
|
||||
'launch', 'world.launch.py')))
|
||||
|
||||
nav = IncludeLaunchDescription(
|
||||
PythonLaunchDescriptionSource(
|
||||
os.path.join(get_package_share_directory('kaiaai_bringup'),
|
||||
'launch', 'navigation.launch.py')),
|
||||
launch_arguments={'use_sim_time': 'true', 'slam': 'True'}.items())
|
||||
|
||||
coverage = Node(package='oomwoo_coverage', executable='coverage',
|
||||
name='coverage', parameters=[{'use_sim_time': True}])
|
||||
|
||||
# give Gazebo + SLAM ~12 s to come up before the robot starts moving
|
||||
return LaunchDescription([gazebo, nav, TimerAction(period=12.0, actions=[coverage])])
|
||||
```
|
||||
|
||||
Reference the launch folder in `setup.py` `data_files` so it installs:
|
||||
```python
|
||||
(os.path.join('share', package_name, 'launch'), glob('launch/*.launch.py')),
|
||||
```
|
||||
(add `import os` and `from glob import glob` at the top of `setup.py`).
|
||||
|
||||
## 5. Build and run
|
||||
|
||||
```
|
||||
cd ~/ros2_ws
|
||||
colcon build --packages-select oomwoo_coverage
|
||||
source install/setup.bash
|
||||
ros2 launch oomwoo_coverage coverage.launch.py
|
||||
```
|
||||
|
||||
Gazebo and RViz open, SLAM starts, and after ~12 s oomwoo-one begins driving itself —
|
||||
forward until it's blocked, then turning — while the map fills in. Open RViz
|
||||
(`ros2 launch kaiaai_bringup monitor_robot.launch.py use_sim_time:=true` in another shell) to
|
||||
watch the map grow.
|
||||
|
||||
## 6. Save the map
|
||||
|
||||
```
|
||||
ros2 run nav2_map_server map_saver_cli -f ~/maps/map
|
||||
```
|
||||
|
||||
## What you just learned
|
||||
|
||||
- created a ROS 2 package, wrote a node that *subscribes to `/scan` and publishes `/cmd_vel`*,
|
||||
- combined *your code + SLAM* in a single `ros2 launch`,
|
||||
- produced a real map from an autonomous run.
|
||||
|
||||
That's the whole loop of developing for OOMWOO. From here, the natural next step is *real
|
||||
coverage path planning* (boustrophedon, wall-following, frontier exploration) — which is
|
||||
exactly the [clean-and-map RFC](https://github.com/makerspet/oomwoo/tree/main/contributions/clean-and-map).

# Simulate the oomwoo-one Robot Vacuum in Gazebo with ROS 2
|
||||
|
||||
> *Draft for makerspet.com (WordPress / Gutenberg).* Post 1 of 2: set up the OOMWOO
|
||||
> software dev environment and drive `oomwoo-one` in simulation — no robot required.
|
||||
> (Post 2 teaches you to write your own OOMWOO code.)
|
||||
|
||||
[OOMWOO](https://github.com/makerspet/oomwoo) is an open-source robot vacuum you build
|
||||
yourself. *oomwoo-one* is the first model. This tutorial gets its ROS 2 simulation running
|
||||
in *Gazebo* so you can develop mapping, navigation, and cleaning behaviours with *no
|
||||
hardware* — everything runs in Docker on *Ubuntu or Windows*.
|
||||
|
||||
You'll get: SLAM mapping, autonomous Nav2 navigation, manual driving, and bumper sensors —
|
||||
the same interfaces the real robot will expose.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- *Docker* — Docker Desktop on Windows/macOS, Docker Engine on Linux.
|
||||
- *An X server* for the GUI windows (Gazebo, RViz):
|
||||
- *Windows:* [VcXsrv](https://sourceforge.net/projects/vcxsrv/) (XLaunch).
|
||||
- *Linux:* native X — nothing to install.
|
||||
- No physical robot.
|
||||
|
||||
## 1. Start the X server (Windows only)
|
||||
|
||||
Launch *XLaunch* (from VcXsrv) and accept the defaults *except*:
|
||||
|
||||
> On the *"Display settings"* page, set *Display number = `0`* (not `-1`).
|
||||
> The Docker container connects to `host.docker.internal:0.0`, so the display number *must
|
||||
> be 0* or no GUI windows will appear.
|
||||
|
||||
Also tick *"Disable access control"* on the "Extra settings" page so the container can
|
||||
connect. Finish the wizard — a tiny X icon appears in your tray.
|
||||
|
||||
On *Linux*, instead allow local Docker to reach your X server:
|
||||
```bash
|
||||
xhost +local:docker
|
||||
```
|
||||
|
||||
## 2. Pull the OOMWOO Docker image
|
||||
|
||||
```
|
||||
docker pull makerspet/oomwoo:jazzy-dev
|
||||
```
|
||||
|
||||
## 3. Start the container
|
||||
|
||||
*Windows (PowerShell):*
|
||||
```powershell
|
||||
docker run --name makerspet -it --rm -v c:\maps:/root/maps -p 8888:8888/udp -p 5555:5555/udp -e DISPLAY=host.docker.internal:0.0 -e LIBGL_ALWAYS_INDIRECT=0 --add-host=host.docker.internal:host-gateway makerspet/oomwoo:jazzy-dev
|
||||
```
|
||||
(`DISPLAY=...:0.0` matches the XLaunch *display 0* from step 1.)
|
||||
|
||||
*Ubuntu / Linux:*
|
||||
```bash
|
||||
docker run --name makerspet -it --rm -v ~/maps:/root/maps -p 8888:8888/udp -p 5555:5555/udp -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --network host makerspet/oomwoo:jazzy-dev
|
||||
```
|
||||
|
||||
Need more terminals into the same container? Open another PowerShell/terminal and run:
|
||||
```
|
||||
docker exec -it makerspet bash
|
||||
```
|
||||
|
||||
## 4. Select the oomwoo-one model
|
||||
|
||||
Inside the container:
|
||||
```
|
||||
kaia config robot.model oomwoo_one
|
||||
```
|
||||
|
||||
## 5. Launch the Gazebo world
|
||||
|
||||
```
|
||||
ros2 launch kaiaai_gazebo world.launch.py
|
||||
```
|
||||
A Gazebo window opens with oomwoo-one in a living-room world.
|
||||
|
||||
## 6. Start SLAM mapping
|
||||
|
||||
In a new container shell (`docker exec -it makerspet bash`):
|
||||
```
|
||||
ros2 launch kaiaai_bringup navigation.launch.py use_sim_time:=true slam:=True
|
||||
```
|
||||
|
||||
## 7. Open the RViz monitor
|
||||
|
||||
```
|
||||
ros2 launch kaiaai_bringup monitor_robot.launch.py use_sim_time:=true
|
||||
```
|
||||
Watch the map build as the robot moves.
|
||||
|
||||
## 8. Drive it manually
|
||||
|
||||
```
|
||||
ros2 run kaiaai_teleop teleop_keyboard
|
||||
```
|
||||
Use the keyboard to drive oomwoo-one around and fill in the map.
|
||||
|
||||
## 9. Autonomous navigation
|
||||
|
||||
In RViz, click *"Nav2 Goal"* and click-drag a destination — oomwoo-one plans a path and
|
||||
drives there on its own.
|
||||
|
||||
## 10. Check the bumper sensors
|
||||
|
||||
```
|
||||
ros2 topic echo /bumper_left
|
||||
ros2 topic echo /bumper_right
|
||||
```
|
||||
Drive into a wall and watch the left/right contact events fire.
|
||||
|
||||
## 11. Save your map
|
||||
|
||||
```
|
||||
ros2 run nav2_map_server map_saver_cli -f ~/maps/map
|
||||
```
|
||||
On Windows the map lands in `c:\maps`; on Linux in `~/maps`.
|
||||
|
||||
## What's next
|
||||
|
||||
You now have a full oomwoo-one simulation: SLAM, Nav2, teleop, and bumpers, exactly the
|
||||
interfaces the real robot exposes. In *Post 2* you'll write your *first OOMWOO ROS 2
|
||||
package* — a node that drives a coverage path *while* mapping — and launch it with
|
||||
`ros2 launch`.

# OOMWOO Design Document
|

|
||||

|
||||

|
||||
|
||||
## 1. Design research — what makes vacuum users happy
|
||||
|
||||
We reviewed the 2025–2026 consumer robot vacuum landscape (global + China-sourceable
|
||||
brands, budget → flagship) across RTINGS, VacuumWars, Reddit r/robotvacuums, and
|
||||
reviewer blogs, then adversarially fact-checked the key claims. The point: copy the
|
||||
solutions that correlate with happy users, skip the ones that need commercial scale.
|
||||
|
||||
### Suction — a sourcing problem, not an engineering one
|
||||
Real-world cleaning does *not* track advertised suction (Pa). ~$500 mid-tier
|
||||
models beat flagships in pickup tests. A moderate *sealed* sourced motor + a good
|
||||
brush + a *tight airflow seal* matches flagship cleaning — *no custom-molded
|
||||
impeller needed.* Airflow sealing (bin/fan/brush seams) matters more than raw Pa.
|
||||
[(source)](https://www.thesmarthomehookup.com/the-best-300-600-robot-vacuums-they-beat-the-flagships/)
|
||||
|
||||
### Navigation & "never gets stuck" — the #1 user pain, hardest to replicate
|
||||
Best obstacle avoidance comes from *sensor fusion* (LiDAR + a floor-level 3D-ToF
|
||||
or RGB camera + AI object recognition), not any single sensor. LiDAR is structurally
|
||||
*blind below its ~10 cm turret*, which is exactly why robots eat cables and socks.
|
||||
The Eufy Omni S2 ($1,599) was the only model in one test to pass all 24 obstacles —
|
||||
and it has the full vision stack. *Never-stuck is commercial-scale.*
|
||||
- *For OOMWOO:* v1 leans on the *bumper* for low/LiDAR-invisible obstacles (this
|
||||
is already how the [clean-and-map RFC](../contributions/clean-and-map) handles it).
|
||||
Camera + AI vision avoidance is a *later / experimental* goal, not an MVP promise.
|
||||
Don't position OOMWOO as out-navigating commercial flagships; position it as an
|
||||
open platform to *experiment* with navigation and vision.
|
||||
[(source)](https://vacuumwars.com/best-robot-vacuums-with-obstacle-avoidance/)
|
||||
|
||||
### Brush — anti-tangle is what users notice
|
||||
Rubber beats bristle, and a *tapered, one-side-mounted roller* resists hair-wrap
|
||||
best (hair tangling is a top complaint). Easy to 3D-print or source compatible.
|
||||
|
||||
### Mop — dual-spinning is the replicable sweet spot
|
||||
Performance ladder: flat drag pad (worst) → *dual spinning pads* (mid) →
|
||||
self-washing roller (best). But the roller mop's "better stains / less residual
|
||||
water" edge was *refuted* under fact-checking — it's overstated. A 3D-printed
|
||||
*dual-spinning* mop is competitive and DIY-able; *skip the self-washing roller*
|
||||
(and its multifunction wash/dry dock) for now.
|
||||
[(source)](https://vacuumwars.com/robot-vacuum-mop-systems/)
|
||||
|
||||
### Dock — basic is DIY-able, full-service is not
|
||||
A *basic charging dock* is well within reach (print the housing; source contacts +
|
||||
adapter + IR beacon). *Auto-empty / mop-wash / hot-dry all-in-one docks* are
|
||||
commercial-scale — defer, or use an off-the-shelf corded vac for emptying.
|
||||
|
||||
### Cloud-free / local control — the real differentiator
|
||||
[Valetudo](https://github.com/Hypfer/Valetudo) gives cloud-free MQTT/REST local
|
||||
control across ~10 brands. *Dreame* is the most rootable (≈16 models) and the
|
||||
safest donor to study. Cloud-free local operation is OOMWOO's positioning advantage.
|
||||
|
||||
### Well-loved models worth studying
|
||||
Eufy Omni S2 (obstacle avoidance), Narwal Flow (roller mop), Ecovacs Deebot T90 Pro
|
||||
Omni (~$499 all-rounder), Dreame X40 Ultra (dual-spinning mop; Dreame = best donor).
|
||||
|
||||
> *Caveats:* the top-level dimensions (suction-decoupling, sensor-fusion, mop
|
||||
> ladder) are primary-source and verified. Per-model rankings are *directional*,
|
||||
> from single-run reviewer tests. Rootability is *per hardware revision* —
|
||||
> re-verify any specific donor unit before buying to root.
|
||||
|
||||

|
||||
|
||||
## 2. Print vs source strategy
|
||||
|
||||
*Rule of thumb: print geometry, source mechanisms and wear items.* Anything with a
|
||||
gearbox, encoder, rubber compound, spring, pump, or bearing is precision you can buy
|
||||
for a few dollars; anything custom-shaped that mates with the OOMWOO chassis, print.
|
||||
|
||||
| Component | Source or 3D print | Why / how |
|
||||
|---|---|---|
|
||||
| *Driving wheel assemblies* | *Source (whole module)* | Complete drive modules (gearmotor + encoder + suspension + rubber tire). 3D print at most an adapter bracket. Why? Requires advanced skill - possibly SLA for gearbox, FDM TPU tire. The #1 "don't print it" part. |
|
||||
| *Universal / caster wheel* | *Print* or source wheel/ball caster. | Likely a simple passive swivel, possibly TPU. |
|
||||
| *Side brush assembly* | *Hybrid* | Source brush + small gearmotor; print the mount. Fit a *common replaceable brush*. Fixed (not extendable) for v1. |
|
||||
| *Main brush* | *Source / hybrid* | Tapered rubber anti-tangle roller in a *common wear-part size*; source compatible, or print core + rubber. |
|
||||
| *Bumper* | *Hybrid* | Print floating shroud; source lever microswitches + return springs. |
|
||||
| *Dust bin / water tank* | *Print body + source guts* | Print custom body (mates airflow); source filter (common HEPA size), gasket (or TPU print), latch spring. Water tank adds a sourced *pump + solenoid valve + tubing*. |
|
||||
| *Mop lift* | *Hybrid (P2)* | Print cam/linkage; source a small *servo or geared motor*. |
|
||||
| Mop disposable cloths | *Source* | Source (easier) or DIY sew. |
|
||||
| Mop dryer | *Source* | Source the mop dryer. |
|
||||
| *Enclosure / top shell* | *Print* | Custom cosmetic/structural; no off-the-shelf equivalent. Design for splitting to fit common print beds. |
|
||||
| *Dock (basic charge)* | *Print housing + source contacts* | Source *pogo pins / spring contacts / magnets* (magnets can carry [10 A](https://xdaforums.com/t/home-made-pogo-pin-charging-dock.2019847/)) + wall adapter + IR-beacon LEDs. Plenty of [DIY precedent](https://www.instructables.com/Roamer-the-Self-Charging-Companion-Robot/). |
|
||||
| *Auto-empty dock* | *3D print enclosure + source bin/fan* | Needs its own fan + bin (commercial-scale). Off-the-shelf corded vac bolted to a printed dock is the DIY path. |
|
||||
| *Mop dock* | *3D print enclosure + source water tanks/hookups* | Needs its own fan + bin (commercial-scale). Off-the-shelf corded vac bolted to a printed dock is the DIY path. |
|
||||
| Battery, LiDAR, motors, PCB, fasteners, bearings, gaskets | *Source* | Standard sourced parts (custom PCB + LiDAR aside). |
|
||||
| Single Board Computer | *Source* | Raspberry Pi 5 4GB or better for first model. |
|
||||
| Input/Output board | *Custom* | No DIY-vacuum I/O PCBs I'm aware of. I'll design a custom PCB for sensors and motor drivers. |
|
||||
| Cameras, sensors, LiDAR | *Source* | Color + distance cameras for top-tier obstacle avoidance. IR cliff, side proximity sensors. Ultrasonic carpet sensor. |
|
||||
|
||||
*Sourcing strategy:* deliberately spec sourced wear parts (brushes, filters, wheel
|
||||
modules) in *common, abundant sizes* so users buy cheap "universal" / Roomba-style
|
||||
replacements anywhere. A selling feature *and* less inventory to stock.

## 3. Feature decisions
|
||||
|
||||
### 3.1 Extendable side brush — *fixed for v1*
|
||||
The extendable arm (e.g. Roborock FlexiArm) is a *genuinely loved* feature — best
|
||||
corner-cleaning scores and strong reviews
|
||||
[(source)](https://vacuumwars.com/vacuum-wars-best-robot-vacuums/). But it's a
|
||||
mechanically complex actuated mechanism. A well-placed *fixed* side brush captures
|
||||
most of the corner benefit at a fraction of the complexity. Extendable is a great
|
||||
*P2+ community mod*, not an MVP requirement.
|
||||
|
||||
### 3.2 Body shape — *round*
|
||||
D-shape cleans corners/edges better, but the real-world advantage is "smaller than
|
||||
most people expect," and a well-engineered round robot with good side brushes
|
||||
performs as well or better in most homes
|
||||
[(source)](https://www.ecovacs.com/us/blog/round-vs-square-robot-vacuum). Round wins
|
||||
for a DIY/printable platform:
|
||||
1. Simpler to design, print, and seal.
|
||||
2. Navigates better — rotates in place, backs out the way it came (D-shape
|
||||
complicates every nav/recovery RFC).
|
||||
3. Natural fit for the spinning 2D LiDAR turret.
|
||||
4. Matches the round teardown reference we're porting.
|
||||
5. Corners are better solved by the side brush (later extendable) than by body shape.
|
||||
|
||||
*Decision: round body + fixed side brush now, extendable side brush later.*
|
||||
|
||||

|
||||
|
||||
## 4. Compute (SBC)
|
||||
|
||||
*v1: Raspberry Pi 5 (4 GB).* Chosen to onboard the large Raspberry Pi community —
|
||||
the biggest contributor wedge. Runs ROS2 + LiDAR SLAM + Nav2 comfortably. No on-board NPU.
|
||||
|
||||
- *ML vision option — Hailo AI HAT.* Add the RPi M.2 AI Kit (Hailo-8L, ~13 TOPS) for
|
||||
real-time camera obstacle detection: keeps the entire RPi ecosystem advantage *and*
|
||||
gains an NPU. *Check the board-stack height* — a vacuum is only ~10 cm tall and
|
||||
the M.2 HAT adds Z. Evaluate alternatives (Coral USB/M.2 accelerator, or lighter
|
||||
CPU-only models) against the height budget.
|
||||
- *Later: Rockchip RK3588 / RK3576.* Orange Pi 5, Radxa Rock 5B, Banana Pi CM5 —
|
||||
built-in *6 TOPS NPU*, RKNN toolkit, YOLO ~65 ms/image. Cheaper and integrated, but
|
||||
driver / ROS2 / kernel maturity *lags RPi*, so it's a *later* move, not the
|
||||
community-onboarding one.
|
||||
|
||||
---
|
||||
|
||||
## 5. I/O board (custom, JLCPCB)
|
||||
|
||||
No off-the-shelf DIY-vacuum I/O board exists, so we design one. It carries an *MCU
|
||||
running micro-ROS* that talks to the SBC over a fast serial / USB link: the SBC does
|
||||
ROS2 / SLAM / nav / vision; the board does real-time motor + sensor I/O.
|
||||
|
||||
*MCU:* STM32G070RBT6 (LQFP64, ~$0.93 @ 100 pcs) — cheap, lots of peripherals.
|
||||
*Pin-budget risk:* the full peripheral set below is a lot for 64 pins. Do a
|
||||
pin-allocation spreadsheet before committing. Offload the *BLDC fan to an external
|
||||
ESC* (1 PWM pin instead of in-MCU FOC) to save pins and complexity. If still tight,
|
||||
consider the STM32G0B1RET6 (same family, more peripherals/RAM) or a 100-pin part.
|
||||
|
||||
*LiDAR (3irobotix CRL-200S):* wires to the I/O board. The board *drives the LiDAR
|
||||
motor* (MOSFET + closed-loop speed control using the LiDAR's RPM feedback) and *passes
|
||||
raw LiDAR data through the MCU to the SBC* over the fast serial link. *Confirm the MCU
|
||||
UART bandwidth handles the CRL-200S data rate.*
|
||||
|
||||
Cross-checked peripheral list (your running list + `[+]` = additions to consider):
|
||||
|
||||
*Sensors*
|
||||
- 2D LiDAR (CRL-200S) — motor-driven + data passthrough to SBC
|
||||
- IR cliff / proximity / docking
|
||||
- Bumper micro-switches (+ optional optical/IR bumper)
|
||||
- Wheel encoders
|
||||
- Carpet ultrasonic sensor
|
||||
- Color camera → *connects to the SBC's CSI/USB, not this board*
|
||||
- VL53L7CX distance sensor (I²C)
|
||||
- Water tank level (full/empty)
|
||||
- Dust bin present / lid open-closed
|
||||
- Battery level / fuel gauge
|
||||
- Dock-connected / charge sense
|
||||
- IMU
|
||||

|
||||
|
||||
*Motor drivers*
|
||||
- Main wheels ×2
|
||||
- Main brush
|
||||
- Side brush(es)
|
||||
- `[+]` *Mop pad spin motor(s)* — for dual-spinning pads (you listed mop *lift* but not *spin*)
|
||||
- Mop lift servo
|
||||
- Water pump (low-side MOSFET)
|
||||
- Vacuum fan (BLDC) — via *external ESC* (recommended)
|
||||
- LiDAR motor (MOSFET, closed-loop)
|
||||
|
||||
*Power*
|
||||
- Battery connector
|
||||
- Charging circuit (charge-controller IC)
|
||||
- Dock contacts
|
||||
- BMS interface
|
||||
- Current sense (per-rail and/or per-motor for stall / tangle detection)
|
||||
- DC-DC converters (5 V for SBC, 3.3 V logic, motor rails)
|
||||
- Power on/off button + soft-latch power circuit
|
||||
- `[+]` Protection: reverse-polarity, over-current fuse / eFuse, inrush limiting
|
||||
|
||||
*Audio / UI*
|
||||
- Speaker amp + connector (audio in from the SBC)
|
||||
- Mic placeholder
|
||||
- Power / status LEDs
|
||||
- Buttons (power, dock, clean)
|
||||
- `[+]` Buzzer (cheap fallback if the speaker amp is deferred)
|
||||
|
||||
*Host link:* USB or high-speed UART between MCU and SBC, carrying micro-ROS *and*
|
||||
the LiDAR passthrough — confirm bandwidth covers both.
|
||||
|
||||
> *Scope note:* the *wash/dry dock has its own controller* (ESP32 + WiFi) for its
|
||||
> pumps / heater / fan / water-level. Those are *not* on the robot I/O board.

|

|
||||
## 7. Water system
|
||||
|
||||
*Robot:* an onboard *clean-water tank* (printed) → *solenoid diaphragm pump* (what
|
||||
commercial units use) → mop head. For spinning pads, dirty water stays in the pads until
|
||||
the dock washes them.
|
||||
|
||||
*Dock tiers (where the water complexity lives):*
|
||||
- *Auto-empty:* dock fan + bin/bag suck the robot's dustbin out through a sealed port.
|
||||
The off-the-shelf-corded-vac approach works here.
|
||||
- *Wash + dry:* *clean tank + dirty tank* (printed) + *two pumps* + a wash
|
||||
tray/roller + a *hot-air blower (heater + fan)*. Wash *must* include hot-air dry —
|
||||
wash-without-dry breeds mildew/odor. Needs its *own ESP32 + WiFi controller*.
|
||||
- *Plumbing hookup:* offer as an *option* on the premium dock (pump + supply/drain
|
||||
lines + valve); default to tank-based (direct plumbing needs pro install). Skip exotic
|
||||
water-recycling (e.g. silver-ion distillation).
|
||||
- DIY parts are cheap/common: 12 V diaphragm or peristaltic pumps, solenoid valves,
|
||||
silicone tubing, float / capacitive level sensors.
|
||||
|
||||

|
||||
|
||||
## 8. Budget target
|
||||
|
||||
*Target: ~$100–200 sourced parts + Raspberry Pi 5 4 GB*, aiming at the capability of a
|
||||
mid-range ($500–600) commercial vacuum.
|
||||
|
||||
- *Verdict: realistic for the mechanicals + core sensors* at the low–mid end, and it
|
||||
compresses at volume. But *mopping + premium obstacle detection* (ToF + color camera
|
||||
+ an NPU accelerator) are exactly the line items that push toward / past $200 — the
|
||||
Hailo HAT alone is ~$70. So $100–200 holds for a capable vacuum; "premium vision now"
|
||||
wants a +$70-ish allowance (or defer the NPU to the Rockchip generation).
|
||||
- *Sanity check vs commercial:* a $500–600 LiDAR vacuum has roughly a *$120–180 FOB
|
||||
BoM at 5,000 MOQ*. Our low-qty numbers are coherent — we trade *no tooling/molds*
|
||||
(3D print) for *higher per-part cost* (no volume).
|
||||
- *Set builder expectations honestly:* total DIY spend (kit + RPi 5 + LiDAR + margin)
|
||||
lands *above* a commercial unit's BoM. The value proposition is *openness, local
|
||||
control, and hackability — not beating Roborock on price.*
|
||||
|
||||
---
|
||||
|
||||
## 9. Product lineup — shared base, three dock tiers
|
||||
|
||||
One robot base, three dock tiers, released in order:
|
||||
1. *Basic charging dock* (first release — simplest, MVP-aligned).
|
||||
2. *Auto-empty dock* (dust).
|
||||
3. *Auto-empty + mop-wash + hot-dry dock* (the full-service tier).
|
||||
|
||||
Notes:
|
||||
- Mirrors how commercial brands segment (same robot, dock tiers) and fits the
|
||||
swappable-module philosophy.
|
||||
- The *mop hardware (spinning pads + onboard water tank) is an add-on module* on the
|
||||
shared base — only the mopping models carry it; the base is otherwise constant.
|
||||
- The *wash+dry dock is almost its own mini-product* (pumps, heater, tanks, ESP32).
|
||||
Correctly the last and hardest deliverable after the robot itself.
|
||||
- Skip a wash-*only* dock — drying is mandatory (odor).
|
||||

|
||||
|
||||
## 10. Obstacle detection strategy (premium hardware + community ML)
|
||||
|
||||
Targets the #1 user pain (getting stuck / eating cables). Strategy: *premium hardware
|
||||
now, ML maturity via community contribution over time.*
|
||||
|
||||
- *Sensors:* *VL53L7CX* multizone ToF (8×8, *90° FoV*, ~350 cm — wider FoV than the
|
||||
L5CX's 63°, better coverage) *+ color camera.* The ToF alone detects the low / small /
|
||||
cliff objects the *LiDAR is blind to*, so v1 gets real "doesn't eat cables" value
|
||||
*before* any ML matures — de-risks the feature.
|
||||
- *ML:* the *camera + model* is where the NPU matters (Hailo HAT now, Rockchip NPU
|
||||
later); real-time RGB detection won't run well on the RPi 5 CPU.
|
||||
- *Community-labeled household-obstacle dataset* is a legitimately novel contribution
|
||||
track — every contributor's home is training data. Treat it as a first-class
|
||||
contribution track alongside the RFCs; it doubles as community-building.
|
||||
|
||||
---
|
||||
|
||||
## 11. Still to research / open decisions
|
||||
|
||||
- *Battery:* chemistry (Li-ion 3S/4S?), specific cells + BMS, charge profile — *safety review*.
|
||||
- *BLDC fan ESC:* select an off-the-shelf ESC vs in-MCU drive.
|
||||
- *Filter:* pick a common, abundant filter size as the interface standard.
|
||||
- *Gasket sourcing* vs TPU printing for airflow seals.
|
||||
- *Dock docking signal:* IR beacon protocol / fiducial / reflective marker.
|
||||
- *Fastener / heat-set insert standard* (ties to ARCHITECTURE §5.2).
|
||||
- *Confirm:* MCU pin budget, host-link bandwidth (micro-ROS + LiDAR passthrough), Hailo stack height.
|
||||
- Remaining mechanical parts not yet covered above.
