Claim:
1. A gearing system comprising: a worm drive; and a harmonic drive coupled with the worm drive, wherein the harmonic drive serves as the input, and drives the worm drive, wherein the worm drive comprises a worm gear, and a worm shaft meshed with the worm gear, further comprising an input device having a rotating drive shaft, wherein the harmonic drive comprises a wave generator which is engaged with the rotating drive shaft of the input device, wherein the harmonic drive comprises a flexible gearing member, wherein the rotating drive shaft of the input device drives the harmonic drive causing the wave generator to rotate, wherein rotation of the wave generator causes the flexible gearing member to deform and rotate, wherein rotation and deformation of the flexible gearing member causes the worm shaft to rotate, wherein rotation of the worm shaft causes rotation of the worm gear via meshing therebetween, wherein the harmonic drive is disposed between the input device and the worm drive, and wherein the worm shaft is meshed with the worm gear such that an overall output of the gearing system provided at the worm gear is disposed ninety degrees relative to the input provided by the rotating drive shaft.
