Abstract
A vehicle toy has two lateral sides, front and rear ends, an outer perimeter extending around the front and rear ends between the lateral sides, and three pairs of wheels, each pair having a common rotational axis. The wheels of each wheel pair are opposed to one another on the lateral sides. The wheels on each lateral side of the vehicle are arranged in a polygon at the outer perimeter, extending around the front and rear ends between the lateral sides such that adjoining pairs of the wheels define planes which are mutually transverse to one another and which entirely circumscribe the outer perimeter of the vehicle. Two wheel pairs are located proximal the rear end, with one of the two wheel pairs being oriented above the other, and the third wheel pair is located proximal the front end, so that the transverse planes form a triangle. The vehicle is driven by twin electric motors which are radio controlled for remote, independent and separate operation. Each motor is drivingly coupled to the two wheels proximal the rear end on a separate lateral side of the vehicle. The vehicle is balanced and powered sufficiently so that it can rotate and operate on any of the three planes.
