SELF-STABILIZING SKATEBOARD
First Claim
1. An electric skateboard, comprising:
- a board including first and second deck portions each configured to receive a left or right foot of a rider;
a wheel assembly disposed between the first and second deck portions and including a ground-contacting element;
a motor assembly mounted to the board and configured to rotate the ground-contacting element around an axle to propel the skateboard;
at least one sensor configured to measure orientation information of the board; and
a motor controller configured to receive orientation information measured by the sensor and to cause the motor assembly to propel the skateboard based on the orientation information;
wherein the skateboard includes exactly one ground-contacting element.
