Abstract
Robot arms are driven (or powered) either by electric motors or by fluid power actuators. Electric motor actuators for industrial robots can be dc servomotors or ac servomotors, but a special type of motor called a stepper motor is often used on educational robots. In dc motors current is supplied to the rotor through brush contacts to a commutator; ac servomotors are induction motors, which require no contacts to the rotor.
