Abstract
A harmonic drive, having: a housing; an output shaft within the housing; an input shaft within the housing, the input shaft is configured for being in a first position in which rotation of the input shaft rotates the output shaft, and a second position that is axially offset from the first position, in which rotation of the input shaft does not rotate the output shaft; a solenoid coil within the housing that, when energized, moves the input shaft to the second position; and a spring within the housing that, when the solenoid coil is not energized, moves the input shaft to the first position.
