PR 36 - Perfect Robot XXXVI
This robot was built to compete in four sumo events.  After the first two, I decided to retire it, because it's matches weren't even close.
PR36 was designed to be the Perfect Robot (number 36...)  The name came from my favorite name for a computer game, Final Fantasy 8.  What happened to the first seven final fantasies?

PR36 had all the features I could put into a sumo robot.
2 RCXs and 2 battery boxes held 24 batteries.
10 motors, 2 to flip polarity switches, and 8 for driving the robot.
8 wheels
8 sensors,
    4 light for edge detection
    2 rotation for speed/turning detection
    2 touch to detect lifting/edge of field
All connected with 24 wires, and 26 gears

Over 1000 lines of code

Total Weight: 6.6 lbs
Estimated cost (of parts) ~$800
At Brickfest the average match time was 74 seconds.  PR36's average time was 7.4 seconds.  In it's lifetime of 13 battles, PR36 won in an average of 6.8 seconds.
