A harmonic drive assembly with selective disconnect includes a motor with a motor drive shaft, a harmonic drive operatively coupled to the motor drive shaft, and a wave generator operatively coupled to the motor drive shaft and a flex gear of the harmonic drive. Also included is a ring gear of the harmonic drive operatively coupled to the flex gear with a plurality of ring gear teeth configured to mesh with a plurality of flex gear teeth. Further included is an output shaft operatively coupled to the harmonic drive. Yet further included is a retracting mechanism configured to selectively retract the motor drive shaft and the wave generator to decouple the motor drive shaft and the wave generator from the harmonic drive, wherein a clearance between the ring gear teeth and the flex gear teeth is established upon retraction of the motor drive shaft and the wave generator.
