+
+## 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/`. 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*.
