Abstract
A single channel continuous wave transmitter and receiver to produce a control signal to change the direction of the drive motor of a toy such as a model car having steerable wheels. A single electric motor provides the propulsion for the toy in one direction through the engagement of a planetary gear with a primary drive gear. The planetary gear is mounted on a rotatable ring surrounding the drive gear. When the direction of the motor is changed, the driver gear on the motor which is meshed with the planetary gear causes the planetary gear and ring to rotate until the planetary gear engages a secondary drive gear thereby changing the direction of travel of the vehicle. The rotational movement of the ring is also used as an actuator mechanism. This actuator mechanism is coupled to a cam that is in return coupled to the steering of the vehicle. The actuator mechanism responds to each cycle of change in direction of the drive motor, backward and then forward, to advance the cam through discrete positions thereby controlling the steering and driving force of the vehicle with one control signal.
