A strain sensing arrangement includes a rigid annular ring, which is co-axial with an upper central boss and a lower central boss. An upper array of vertical, relatively flat, wide and flexible beams are connected to the upper boss and the ring and a lower array of horizontal beams are connected to the lower boss and the ring. Each of the beams are provided with a strain gauge on each side thereof for detecting any deflection of the beams. When the arrangement is utilized in an assembly robot, the end of an arm of the robot is inserted downwardly into the upper boss and a gripper is inserted upwardly into the lower boss, so that the strain gauges can detect torsional and/or linear strain acting on the arrangement caused by relative rotation of the gripper with respect to the arm.

A strain sensing arrangement comprising a first support member, two further support members arranged coaxially with respect to the first support member, a first array of beam members interconnecting said first support member and one of said further support members, a second array of beam members interconnecting said first support member and the other of said further support members, and respective strain sensing means associated with the beam members of the first and second arrays for sensing relative axial displacement of the first support member and said one of the further support members and relative angular displacement of the first support member and said other of the further support members and for generating electrical signals indicative of angular and/or axial displacements which are sensed.
