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.
Claims6
A balancing toy comprising:
- a. a chassis incapable of supporting a person, the chassis characterized by an instantaneous tilt in a fore/aft plane with respect to a vertical direction;
- b. a pair of laterally disposed wheels coupled to the chassis for motor-driven rotation with respect to the chassis;
- c. a sensor for measuring the tilt of the chassis;
- and
- d. a circuit for governing wheel rotation to maintain balance of the toy on the basis of the tilt of the chassis.

A balancing toy comprising:
- a. a chassis incapable of supporting a person, the chassis characterized by a center of gravity;
- b. a pair of laterally disposed wheels rotatable about an axis, the wheels rotatably coupled to the chassis and the axis disposed beneath the center of gravity of the chassis;
- and
- c. a motor for driving the wheels in such a manner as to maintain balance of the toy with respect to tipping in a fore/aft direction during operation.
