ABSTRACT:
A mechanized ball includes a hollow sphere having a removable hatch through which a powered ball driving unit can be placed within the sphere and removed therefrom. The ball driving unit can be electrically or mechanically powered and may be in the form of a single powered driving wheel or a self-contained four wheeled toy vehicle. The vehicle may be guided within the ball by a strut and/or a spring device which contacts an interior part of the ball. In some species the ball may be steered by a weight which is moved back and forth along a dual helical groove on a diametral support from which a single powered drive wheel is suspended.
