Abstract:
An electric apparatus comprising:a platform having a plurality of equally spaced conductors of alternating positive and negative polarity, said conductors being carried by an upper surface of said platform;a remotely controlled electric vehicle having a linkage carried by said vehicle;at least three pairs of electrical contact surfaces carried by said linkage, said pairs of electrical contact surfaces being longitudinally spaced along the bottom surface of said vehicle and being positioned relative to each other in a laterally extending direction so that at least two of said contact surfaces are always in contact with the two conductors, regardless of the direction of movement of said vehicle on said platform;a voltage rectifier circuit for supplying a respective positive and negative voltage from said platform conductors to said vehicle;wherein when said vehicle is on said platform, said linkage contains an operative electrical connection with said platform conductors at all times, thereby permitting the vehicle to be operated along all points and in any direction relative to the platform.
