Step 6 Whats under this bust

Next is a look under the shoulders. This is where the head is controlled; it can tilt right, left, up and down. Two motors control these functions in the X-Y axis using worm gears and a gear box. Notice the large silver washer. In between is a thick rubber washer, so the motor gear box can move without breaking or locking up. The board to the right of the center motor is an Hbridge circuit for controlling the movement of the motors forwards and backwards. Also in the motor gearbox is a PT sensor ( Photo Transistor) for detecting speed and lack of motor movement. On the far left and far right is the board for the IR sensors on the vest. The center bottom board is a power distribution board.
