摘要：
A drive unit for providing drive from a robot arm to an instrument comprises a plurality of drive elements for engaging corresponding elements of the instrument, and a load cell structure. Each drive element is movable along a drive axis and the drive axes of each of the drive elements are substantially parallel to each other. The load cell structure includes a plurality of deflectable bodies coupled to the drive elements for sensing load on the drive elements parallel to their drive axes, and a frame. The frame includes an integral member supporting the deflectable bodies in such a way as to isolate each deflectable body from the load applied to the or each other deflectable body.
