The electrosurgical connection unit 708 includes an input port 802 connectable to an electrosurgical generator 726, an output port 804 connectable to an electrosurgical instrument 712 attached to the robot arm and one or more activation switch units 806, 808 which cause an activation signal to be output from the input port to cause the electrosurgical generator to generate a driving electrosurgical signal which is received on the input port. A connection switch unit 810 is usually open to reduce the chance of return energy from another electrosurgical instrument taking the active path 814 through the instrument rather than the appropriate return path. On activation the connection switch unit causes the input port to be electrically connected to the output port such that, the driving electrosurgical signal received on the input port is output on the output port. A control unit 812 is configured to, in response to receiving a control signal from an external computing device e.g., a surgeon’s console, cause the connection switch unit to be activated and subsequently cause activation of an appropriate activation switch unit. Allows operation via the surgeon’s robot control console and does not require further pedals or buttons
