Our game strategy was ridiculously simple, and so, it was ridiculously consistent. First, the robot would use the 4 IR-LED/phototransistor pairs to figure out whether it was facing a wall or not. If the robot was facing a wall, it would reverse down the length of the board and push balls into a territory, hitting a bump sensor when it reached the edge of the board. If the robot was not facing a wall, it would drive straight forward down one length of the board and push balls into a territory, again hitting a bump sensor when it reached the edge of the board.

Then, it would stop. That's it.

Hence, our team name: Team Stationary State .
