Claim:
1. A transmission system, the system comprising: a first rotor having a first drum configured to rotate about its axis of rotation; a second rotor having a second drum configured to rotate about its axis of rotation, where the first rotor is constrained to orbit concentrically about the axis of rotation of the second drum; and a belt encircling the first and second drums so as to couple the first and second rotors such that as the first rotor moves concentrically around the second rotor, the belt advances about a circumference of the second drum; where the belt and an outer surface of the second drum are configured to be electrically coupled, and where the belt and the outer surface of the second drum are configured such that a belt wave drive is engaged by applying a voltage signal to at least one of the belt and the second drum to produce traction between the belt and the second drum.
