    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.

    摘要: A robotic apparatus has eight actuators (M0-M7) and a linkage (LINK 0-LINK 5) that actuates an end effector. Three serial macro freedoms have large ranges of motion and inertias. Four serial micro freedoms have small ranges of motion and inertias. Translation of the end effector in any direction is actuated by at least one micro joint and at least one macro joint. The apparatus can be part of a master and slave combination, providing force feedback without any explicit force sensors. The slave is controlled with an Inverse Jacobian controller, and the mater with a Jacobian Transpose controller. A slave having more degrees of freedom (DOFs) than the master can be controlled. A removable effector unit actuates its DOFs with cables. Beating heart surgery can be accomplished by commanding the slave to move with a beating heart and cancelling out any such motion in the motions perceived by the master.
