Abstract
A toy vehicle having a set of motor-driven drive wheels for moving it forwardly and a motor-driven steerable wheel assembly for effecting changes in the direction of movement of the vehicle. The vehicle has a radio receiver coupled to the drive motor of the steerable wheel assembly for energizing the drive-motor when signals are received by the receiver from a transmitter remote from the vehicle itself. In one embodiment, the steerable wheel assembly includes a single wheel rotatable about a vertical axis in one direction through an angle of 360.degree.. In another embodiment, the steerable wheel assembly includes a pair of spaced wheels interconnected by a linkage shiftable back and forth in response to the rotation of a coupling member which rotates in one direction in a 360.degree. arc. The transmitter has input means including a microphone and a Schmitt trigger unit or a one-shot multivibrator. The drive motor for the steerable wheel assembly can include a stepping motor.
