ABSTRACT:
A steering control mechanism for a model vehicle, e.g. a small toy vehicle, includes an electromagnetic coil wound around the wheel shaft of one of the wheels of the toy vehicle. Adjacent and facing one end of this coil are provided one or more permanent magnets on the vehicle chassis. Current is selectively applied to the coil so as to cause the wheel shaft to rotate either towards one or the other pole of the permanent magnets. The mechanism also includes position sensing means which may provide a feedback control signal to a controller to provide for progressive turning of the wheels and/or to provide automatic centering of the wheels when it is desired for the vehicle to move in a straight line.
