Patent Images
1. A balancing toy comprising:
- a. a chassis incapable of supporting any 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;
d. a circuit for governing wheel rotation to maintain balance of the toy on the basis of the tilt of the chassis; and
e. a power source for powering the wheels in motor-driven rotation, the power source enclosed within a structure having dimensions less than 5 cm.

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.

6. A balancing toy comprising:
-
a. a chassis incapable of supporting any 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;
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; and
d. a power source for powering the wheels in motor-driven rotation, the power source enclosed in a structure having dimensions less than 5 cm.
