Dear Sirs;
      Enclosed is a video presentation of the prototype AT-6060 Pneumatic Robot 
Controller.  The controller was originally designed to overcome the burden 
imposed by the AC output module. Unlike this module, the system I have designed
allows editing of the program as well as storing and retrieving the programs on
5 1/4" diskettes. The prototye software is one hunderedd percent functional, 
however, a new version is being written which allows a simultaneous graphic
representation of the robot as the program is being run to facilitate simple
system debugging.

     Due to limitations in my equipment, the software is curretly available for 
a Tandy Color Computer 3.  This computer is very cost effective ($149, less than
$500 for complete system) and has more than the required performance, as well as
the advanced graphics, to successfully control this robot to it's fullest
extent.  Recently it was brought to my attention that there was a desire to run
such software on the Apple II series, as well as the IBM PC. I have had little
programming experience with these systems. If you were interested in marketing
such a product, it would not be such a bad idea to sell the Color Computer 3 
with the advanced software and controller as a package. Tandy does have an 
excellent discount program.

     The hardware of the interface itself is extremely cost effective. The 
controller hardware can be built for well under $100.  This is prototype 
equipment and at this time is incapable of handling the 120 volt inputs the
robot provides through it's position sensors. The newest version will be able
to access these. In conclusion, I would just like to say that I feel this system
is a much more efficient way to program this robot. Also, please keep in mind 
that this robot is being controlled by a computer system and controller which
added together cost less than $700.  An entire system, including robot, 
controller, software, computer, monitor, and disk drive can be sold for
approximately $7500. Consider the possibilities now open for almost any middle
or high school. For about $7500, a school could purchase and run a complete 
robotic system.  The market for this is extensive, since it places a Lab-Volt
robot system in a competitive price range with Commodore and other systems 
currently on the market.  Please keep in mind that this is all prototpe 
equipment and the presentation was totally unrehearsed, so excuse any "bugs"
or "glitches" that may arise.
 
                                                    Sincerely yours,

                                                      Mike Pepe
