Abstract: A control system configured to control manipulation of a surgical instrument in response to manipulation of a remote surgeon input device. The surgical instrument comprises an end effector having opposable first and second end effector elements connected to a shaft by an articulated coupling. The control system receives a command from the surgeon input device to both (i) change the orientation of the end effector, and (ii) open the first and second end effector elements relative to each other. In response to the command to change the orientation of the end effector, the control system determines an angle ? between the longitudinal axis of the articulated coupling and the end effector. In response to the command to open the first and second end effector elements, the control system determines an opening angle ? between the first and second end effector elements.

Abstract: A control system for a surgical robotic system, the surgical robotic system comprising a remote surgeon console and an articulated surgical robot arm comprising a series of joints extending from a base to a terminal end for attaching to an articulated surgical instrument. The control system comprises a central controller communicatively coupled to and remotely located from an arm controller of the surgical robot arm, the central controller also communicatively coupled to a surgeon input device of the surgeon console.

Abstract: A control system of a surgical robot arm, the surgical robot arm comprising a series of joints by which the configuration of that surgical robot arm can be altered and one or more torque sensors, each torque sensor configured to sense a torque at a joint of the series of joints, the control system being configured to control the configuration of the surgical robot arm to be altered in response to an externally applied force or torque by: receiving sensory data from the one or more torque sensors indicative of a sensed torque state of the surgical robot arm resulting from the externally applied force or torque; mapping the sensed torque state to a selected torque state of a set of candidate torque states; and sending a command signal to the surgical robot arm to drive the robot arm such that the configuration of the robot arm is altered so as to comply with the selected torque state.
