Challenge03Sumo

Rules of the challenge:1 The purpose:  To push the other robot(s) out of the ring, while remaining in the ring yourself.  A robot is declared out of the ring if any part of it goes beyond the tape at the edge of the circle. (Keep this in mind when designing your robot!)

2 The ring: The official mini ring is about 75 cm in diameter.  We will use a roughly circular black ring with a light-colored center.  

3 The robots:  The official mini SUMO robots are 10 inches or less in width and length.  We can modify them as ingeniously as possible so that they are good at pushing our opponent out of the ring.

4 Construction: You could use any of your present robots to start off with and modify them later between rounds, if you think it's worth modifying them.

5 The start of a bout: The robots will be placed inside the ring, facing away from each other. They must be controlled only by your computer program; you are not allowed to push them around by hand! Your robot should start on hearing a loud sound.

6 The program: Use NXT-G.  Add a wait-for-sound block at the beginning of the program.

7 Round Robin competition: Score three points for a win, and one for a tie (no clear victor after 30 seconds); the winner is the robot with the most points after 2 bouts. 

8 FINAL VICTOR  The 4 robots with the most points after the Round Robin will face off in a best of 3 bout playoff: 1 vs 4, 2 vs. 3, with the winners of that cross-over round meeting in a best of 3 final.
