Abstract
A surgical robotic system comprises a surgeon console, remote surgical robot, and a control unit. The surgeon console comprises a base connected to a hand controller by a linkage, the linkage comprising a plurality of joints whereby the configuration of the linkage can be altered. The surgeon console comprises a driver to drive each joint to move. The surgeon console further comprises a presence sensor to sense the presence of a surgeon's hand on the hand controller. The control unit receives user inputs from the hand controller, converts the received user inputs into command signals for driving manipulation of the surgical robot, receives sensory inputs from sensors including the presence sensor, and responds to, during a surgical operation, concurrently detecting from the received sensory inputs (i) the lack of a surgeon's hand on the hand controller, and (ii) an external force additional to gravity acting on the hand controller, by controlling the drivers to drive the joints with a damped response in the direction of the external force.
