ABSTRACT:
A wheel-supported figure toy in the form of a pup has a driving motor to propel it in a forward direction. Proximity sensors in the form of capacitor plates control operation of the motor. When a child's hand or the like approaches the rear of the figure, the capacitance of a first capacitor arrangement is changed and the motor is started and propels the figure forwardly for a predetermined time, then stops. If the hand is placed under the pup's chin, a second capacitor arrangement causes the pup to follow the hand. An RC network determines the time the motor is in operation by holding a monostable vibrator on, which keeps the motor running, after it is started, for the predetermined time interval. The toy also has a sounding device that operates when the figure is being propelled.
