So are you saying that using cables and motor driven pulleys is a better solution ? Most robotic arms I've seen appear to have a motor located at the elbow joint that drives the equivalent of the lower arm either directly or through a gear box. If cables and pulleys give better torque without loss of speed why aren't they in more widespread use in robotic arms ?
