A surgical robotic arm includes an instrument having a plurality of cables that are movable longitudinally and an end effector movable by the cables. The surgical robotic arm also includes a drive unit having a plurality of motors each of which is configured to move one of the cables and a plurality of torque sensors, each of which is configured to measure torque output by one of the motors. The surgical robotic arm also includes a controller configured to receive a torque measurement from each of the torque sensors and control each of the motors to apply a minimum torque to maintain a minimum tension on each of the cables based on the torque measurement from each of the torque sensors.
