An actuator comprising: two motors; an output member; and a harmonic gear comprising: an elliptical wave generator component; a flexible spline component which is coupled to the wave generator by a bearing and flexes to conform to the elliptical shape of the wave generator; and a circular spline component which surrounds and meshes with the flexible spline component. One of the harmonic gear components is coupled to the output member, and each of the other harmonic gear components is coupled to a respective one of the motors.
