    Abstract: A robotic control system is placed in clutch mode so that a slave manipulator holding a surgical instrument is temporarily disengaged from control by a master manipulator in order to allow manual positioning of the surgical instrument at a surgical site within a patient. Control systems implemented in a processor compensate for internally generated frictional and inertial resistance experienced during the positioning, thereby making movement more comfortable to the mover, and stabler from a control standpoint. Each control system drives a joint motor in the slave manipulator with a saturated torque command signal which has been generated to compensate for non-linear viscous forces, coulomb friction, cogging effects, and inertia forces subjected to the joint, using estimated joint angular velocities, accelerations and externally applied torques generated by an observer in the control system from sampled displacement measurements received from a sensor associated with the joint.

    Abstract: A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip.

    Abstract: Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.
