Abstract

A compound harmonic actuator includes a circular gear, a flex gear including permanent magnets and a coil assembly disposed and configured to generate a magnetic field with which the permanent magnets interact to deform the flex gear. The coil assembly is controllable such that the deformation of the flex gear is such that the flex gear engages with the circular gear resulting in flex gear rotation.
