  • Patent number: 9339935
    Abstract: The present invention provides a low profile, compact, scalable concept end-effector for use in robotic handling applications. The end-effector acts as the interface between multi-degree-of-freedom (DOF) manipulator and its base (if applicable), as well as the tools it handles and is compatible with both large manipulator systems such as the Shuttle Remote Manipulator System (SRMS) and Space Station Remote Manipulator System (SSRMS) and smaller dexterous manipulators such as the Orbital Express Dexterous Manipulator System. An active/controlled component is attached to the roll joint(s) at one or both end(s) of the manipulator, with an entirely passive component attached to the structure/tools that the manipulator interfaces with. Interface engagement and mate operations are performed by way of the manipulator roll joint. Once mated, shear pins are extended to lock the mated assembly in place and achieve a high stiffness, zero free play mated interface.
    Type: Grant
