  • Patent number: 4447048
    Abstract: A symmetrical three-degree of freedom compliant structure specifically adapted for use in robotic manipulators interposed between a movable robotic arm and the gripper fingers. The structure is uniquely adapted to serve as both a force sensing device and as an expendable mechanical link or fuse which will break due to sudden extreme forces being applied to said fingers and which is easily replaceable. The structure which comprises three separate elements resolves forces into three orthogonal components; X, Y, and Z. There is no mechanical coupling between the individual elements making up the overall compliant structure. Further, due to a multiple flexible web construction of each element, when an orthogonal force is applied to any one of the elements, the two primary planar regions of the element remain parallel. Thus, no rotational component is introduced into the structure.
