Maker's Pet has launched oomwoo, an open-source robot vacuum that owners build themselves. The robot works by mapping the home with an inexpensive 2D LiDAR sensor and then navigating using ROS 2 and the Nav2 stack on Raspberry Pi, integrating natively with Home Assistant. It can be printed using a regular desktop 3D printer and runs entirely without the cloud, while the hardware, firmware, and software are all open under the Apache 2.0 license. Ilia O of Maker’s Pet is also developing oomwoo in public “from the first commit,” though the project is so early that it doesn’t have any build instructions yet.
Right now, oomwoo is at the request-for-comments stage, with the current v0 milestone covering a 3D-printed chassis, a ROS 2 Gazebo simulation, and LiDAR mapping with manual SLAM, and the compute choice between a Raspberry Pi 5, an ESP32 running micro-ROS, or both is still open. Planned deliverables run from the bill of materials and printable files to firmware and a custom PCB, with the first BoM targeted for around mid-July.
