Abstract:     A balancing toy having a chassis and a pair of laterally disposed wheels coupled to the chassis for motor-driven rotation with respect to the chassis. A circuit governs wheel rotation to maintain balance of the toy on the basis of chassis tilt as measured by a sensor. The sensor may include a gyroscope, and the balancing toy may have a single motor driving both wheels, or separate motors driving each wheel.
