Position Sensors

Position sensors are used by MSM to store motor positions in memory and return motors to stored memory positions. Each sensor is a potentiometer, and is mounted to each motor's transmission cable. When cable rotates, resistance of potentiometer varies, and feedback voltage is monitored by MSM to determine motor position. The MSM stores motor positions by recording each position sensor feedback voltage. When a memorized position is requested, each motor is moved until the position sensor feedback voltage equals feedback voltage stored in memory.
