The RobiOmni is a versatile 4-wheel omnidirectional mobile chassis designed for indoor/outdoor use in surveying, factory transport, and agriculture. Powered by 8 motors (4 drive + 4 steering) and controlled by an ARM-based VCU, it precisely manages vehicle/steering speeds with real-time feedback. Using CAN bus communication, operators can drive the chassis and monitor its status via a host computer. It supports autonomous driving, cruise control, and obstacle avoidance, and includes a ROS-compatible CAN communication package for rapid secondary development.
