THIS PAPER BRIEFLY DESCRIBES THE HARDWARE AND INTEGRATION OF THE COMPONENTS IN THIS SYSTEM. NEXT A MODEL OF THE SYSTEM IS DESCRIBED WHICH INCLUDES PLOTS OF THE TRACKING SYSTEM. FINALLY, AN ALGORITHM IS DESCRIBED TO SELF-TUNE THE GAINS IN THE SOFTWARE CONTROL SYSTEM. ANALYSIS IS PROVIDED FOR VARIABLES THAT AFFECT THESE GAINS.
