makerspet/oomwoo ? reverse-engineered prompt

Build me a clean, polished project for an open source robot vacuum called OOMWOO. It should feel like a real community hardware and software project, with a strong landing page and clear docs that explain what the robot does, how someone would build it, and how it connects locally to Home Assistant with no cloud required.

I want the experience to make sense for a DIY builder, so show the main goals, parts list, 3D printed chassis, Raspberry Pi based control, LiDAR mapping, ROS2 navigation, and Arduino or ESP32 based electronics. Include a simple way to browse the modules and contribution ideas, since this project is meant to be worked on by multiple people. Make it look modern, friendly, and serious, like an actual open source product in progress. If you need current ROS2 or Home Assistant details, look up the latest docs online first.
