A motor position controller energized by radiant energy, includes a member that rotates in response to radiant energy. A sensing means is mounted adjacent the absorbing member to sense rotational movement of the member and to generate a member rotational speed and direction movement signal in response thereto. A processor compares input command signals representing the desired member speed and rotational direction signal with the actual speed and rotational direction signal and generates a radiant energy control signal in response thereto. A radiant energy generating laser, controlled by the processor, transmits radiant light energy of varying magnitude onto the member thereby controlling the member's rotational speed, direction and position. In a preferred embodiment, the member is mechanically engaged to a mechanical joint and is used to control the arm's speed, position and movement.
