A harmonic gear drive includes an input shaft and an output shaft. The input shaft is mechanically coupled to a wave generator which has a varying diameter. The wave generator is positioned within a flex spline which includes external teeth. The external teeth of the flex spline engage with internal teeth of a fixed spline and an output spline when the major diameter of the wave generator is aligned therewith. The output spline has a different number of teeth from the input spline such that, as the wave generator is rotated and the flex spline rotates, the output spline is rotated relative to the fixed spline.

An antirotation stabilizer may include one or more antirotation pads extending from a stabilizer body. Each antirotation pad may be positioned at least partially within a recess formed in the stabilizer body. Each antirotation pad may be coupled to a torsion bar. The torsion bar may couple between the antirotation pad and the stabilizer body and may be under torsional loading such that the antirotation pad is extended from the stabilizer body. The antirotation stabilizer may include one or more rollers.
