ABSTRACT:
Apparatus to control the direction of movement of a mechanism over a surface. The surface is provided with a plurality of substantially parallel strips of conductive material alternately connected to opposite terminals of a source of current supply. The mechanism has a plurality of conductive discs or wipers so disposed that at least two of the wipers contact a pair of the conductors which are each connected to oppositely disposed terminals. The mechanism also has driving means such as wheels for movement and a motor engaged through the wipers for propelling the wheels over the surface. The mechanism can move forwardly, rearwardly, laterally or in a zig-zag motion. Control means are provided between the motor and the driving means so that the direction of movement may be varied in response to the voltage across the alternate conductors engaged by the wipers.
