    22         * Monitor the operating temperature of the !BarrettHand™ so that it does not exceed 65C.  Under normal conditions, the Hand operates between 40 and 60C.  The !BarrettHand™ was designed with non-backdrivable finger joints to take advantage of the motors’ peak operating performance in short bursts.  The spread, however, is backdrivable to aid in target-independent grasping (see Section 9.3.1) and requires constant motor current to actively hold position.  Idling the spread motor, when possible, will help keep the temperature lower.
