ABSTRACT:
A radio controlled guidance and speed control system for a vehicle has spaced receivers for receiving magnetic energy signals from a movable energy source. The signals received vary in accordance with the position of the receivers with respect to the energy source, and are electrically processed to control separate motors driving two wheels of the vehicle for starting, stopping and direction controlling. The circuit for processing the received signals comprises a summing amplifier for speed control, two differential amplifiers for direction control and a gate connected to the summing amplifier through a comparator to provide a stop signal. The circuit provides for a gradual acceleration of the motors. One of the receivers is connected to the gate for developing a stop signal to prevent utilization of ambiguous signals from the other signal receivers.
