Summary:A control system for a surgical robot. The robot comprises: a multi-jointed arm extending from a base to a terminal end with attachment to a surgical instrument; and a surgeon console with an input device. The arm is operable in: a full power mode 601, where the joints are powered by a first power source; and a reduced power mode, where the joints are powered by a second power source. In full power-mode, the control-system controls the arm in a surgical mode 602 by converting input device movements to control signals for moving the arm's joints and should a first-power-source power failure be detected 603, the control-system enables the reduced power mode 604 and transitions from surgical-mode to an arm lock mode by sending signals to lock the arm joints. When in the reduced power mode, the control-system responds to detecting a cessation of the power failure 606 by disabling the reduced power mode, re-enabling the full power mode, and returning control back to the surgical-mode. Preferably, in response to power failure cessation, the control-system will only return control of the arm to surgical-mode when the second power source has a battery capacity above a threshold value 701.
