	tl;dr: Oomwoo is a new open-source robot vacuum project (hardware, firmware, and software) designed to be built from scratch using a Raspberry Pi 5, ESP32, 2D LiDAR, and 3D-printed parts, running ROS 2/Nav2 with native Home Assistant integration and no cloud dependency. The project is in very early stages (v0: basic chassis, Gazebo simulation, manual SLAM) and is being developed in public with modular tasks open for community contribution via GitHub. An optional parts kit will be sold for convenience, but all designs and BOMs remain open for DIY sourcing.
	HN Discussion: ↓DIY component cost is prohibitive compared to cheap commercial lidar vacuums or salvaged parts ↑Open source and modular design enables community contributions and continuous improvement ↑Open hardware and repairability are valuable given commercial vacuums' poor longevity ↑Interest in customizing cleaning logic and navigation behavior for specific challenges •Questions about design choices like circular shape and lidar-only sensing versus image processing
