This document discusses an automatic guided vehicle (AGV) mobile robot that uses differential drive kinematics with omnidirectional motors on an omni base. It has a DC motor, encoder, and IR sharp sensor for distance measurement. The robot controller uses incremental encoders to determine position and direction of rotation. The document also mentions a haki robot with a cylindrical arm, cylindrical joint, and rotating base, as well as an AGV robot used in world skills competitions that has a pneumatic system with a suction cap and venturi block.
