Example Project: Building a Raspberry Pi Robot with the Romi Chassis

This is an expandable robot platform based on the Romi Chassis, Romi 32U4 Control Board, and a Raspberry Pi. With this platform, the powerful Raspberry Pi can take care of high-level tasks like motion planning, video processing, and network communication, while the Romi 32U4 Control Board, which connects to the Pi’s GPIO header, takes care of actuator control, sensor inputs, and other low-level tasks that the Pi is incapable of.
