CD Jukebox

    The CD Jukebox uses three motors and a solenoid.   There is a vertical, horizontal, and forward/backward movement.  Each of the three motors is needed to maneuver the CD into the CD player and back to the rack.  The "end effector" of the jukebox is a lever that uses a solenoid to "grab" the middle of the CD after it is positioned.  On each of the "axes" there is a touch sensor that sends input to the software of the project that tells the software where one of the axes is at the current moment.
