Abstract
Disclosed is a system for driving a spherical wheel that includes a rotating sphere having a plurality of magnetic modules and a fixed body. The fixed body has coil modules that generate a magnetic field by current and partially enclose the rotating sphere so that a portion of the rotating sphere is exposed. A support wheel disposed between the rotating sphere and the fixed body is configured to maintain a substantially constant distance between the rotating sphere and the fixed body and rotatably support the rotating sphere. A sensor provided in at least one of the rotating sphere and the fixed body is configured to measure a rotational speed and a position of the rotating sphere, and a control device is configured to receive driving signals, the rotational velocity and the position measured by the sensor and to transmit a control signal supplying a current to the coil module.
