| 2 | | The third joint in each finger is driven by a brush less servomotor through opposing stainless steel cables that act like tendons transmitting torque from a pulley at the base of the finger out to a pulley at the fingertip joint. If you have purchased the joint-torque sensor option, the difference in tension between the tendon pair is used to determine the torque at the third joint. The fact that we measure the tensions differentially reduces the effect of actual pretension in the cable as long as the cable is not actually loose. |
