The present invention is a harmonic belt drive that uniquely combines desirable characteristics of a traditional harmonic drive with those of a traditional belt drive. The harmonic belt drive includes a rigid arcuate toothed member having an internal surface, an external surface, and a row of teeth radially extending from the internal surface and a belt portal extending between the internal surface and external surface. A multi-lobe cam is rotatably mounted concentric within the rigid toothed member and an elongated toothed belt is disposable between the multi-lobe cam and rigid arcuate toothed member. The toothed belt is radially deflectable by the multi-lobe cam meshing an area of belt teeth with an area of arcuate member teeth. The toothed belt advances by a small amount with each revolution of the multi-lobe cam.
