    摘要: An input device for robotic surgical techniques and other applications has a handle supported by a linkage with a redundant degree of freedom, the joints being movable with at least one more degree of freedom than the handle. At least one joint of the linkage is actively driven to prevent the linkage from approaching singularities of the joint system, motion limits of the joints, and also to drive the linkage toward a freely articulatable configuration. A robotic master controller can include an arm assembly supporting a gimbal having a redundant linkage, with the arm primarily positioning the gimbal in a three dimensional controller workspace and the gimbal coupling the arm to the handle with four rotational degrees of freedom. One or more additional degrees of freedom may also be provided for actuation of the handle, to close the jaws of a surgical grasper.
