ABSTRACT:
A self guided vehicle has a roller deck controllably powered by an electric motor to accept and deliver loads on both the left and right side of the vehicle. An infrared communication system is employed to coordinate the overall transfer of these loads between the vehicle and a docking station. The communication system performs the multiple functions of locating the docking station relative to the left and right side of the vehicle, determining the direction the load is to be transferred, and controlling the direction of motor rotation to effect such a transfer.
