An inverted harmonic gear actuator is provided and includes a motor stator and a motor rotor radially disposed within the motor stator. The inverted harmonic gear actuator also includes a wave generator radially disposed within the motor rotor, where the wave generator has a radially inner surface with a cammed shape. An actuator output shaft is radially disposed within the wave generator. A flex spline is radially interposable between the radially inner surface of the wave generator and the actuator output shaft. The flex spline is deformable to conform to the radially inner surface of the wave generator and drive rotation of the actuator output shaft slower than rotation of the motor rotor.
