Abstract
A robot arm comprising: a first link connected to a second link by a joint, the joint permitting the second link to move relative to the first link; a motor for driving the joint; and a controller for controlling the motor. The controller is configured to electrically brake the motor in response to detection of a fault in the robot arm by applying a braking current to the motor so as to maintain the position of the joint against gravity. The controller only performs this electrical braking if the joint is in a configuration in which the robot arm will droop under gravity if the joint is not actively driven.
