Abstract

A compound harmonic actuator is provided and includes a motor, a flex spline disposed about the motor and a wave generator radially interposable between the motor and the flex spline. The wave generator being rotatably drivable by the motor and shaped to form the flex spline into an elliptical shape with an axis such that wave generator rotations drive rotations of the axis of the ellipse of the flex spline.
