Abstract
A modular radio control unit for use with multiple toy vehicles is disclosed. The control unit is in the shape of a vehicle passenger compartment and is designed to plug into a cavity formed in each vehicle. The control unit contains a control circuit including a radio receiver and a motor drive circuit to control two motors mounted in the vehicle and connected to control the motion of the vehicle. The control unit also contains batteries to provide power to the control circuit and to the motors. A set of contacts is provided in the control unit and in each vehicle so that when the control unit is plugged into a vehicle cavity, the output signals from the drive circuits are provided to the motors to effect remote control of the vehicle in response to commands from a transmitter.
