ABSTRACT:
A force-torque sensor is provided for measuring all six possible force and orque components in the Cartesian coordinate system by means of wire strain gauges. The sensor has two identically designed integral spoke wheels each consisting of a rigid cylindrical outer ring and a central hub interconnected by four spokes. Proximate to the hubs of the two spoke wheels, such hubs being rigidly and solidly connected with each other, wire strain gauges are mounted in pairs on opposed spoke surfaces perpendicular to the central axis, as well as on the opposed surfaces of one diagonal pair of spokes of one of the two spoke wheels, the latter surfaces extending perpendicular to the former.
