This robots name is 'Four Eyes' for the obvious nature of the sonar sensors. The sonars are home made and I have a article at

The robot is a Mini-Sumo and uses some deployable flags intended to fool the opponent into attacking them and not the robot. Overall the strategy works and has helped to make this robot fairly successful.

The electronics board is home made using a Pic 16F628 with Pic basic for code. The drive motors are converted standard servos using external H-Bridge for motor control. The wheels are homemade and use very grippy rubber shelfing material for the tires.

After the start button is pushed the robot waits the mandatory five seconds then the little motors deploy the flags and the robot proceeds to find the opponent and try to push it out of the ring. The robot has two reflective IR sensors on the bottom to tell it the its near the black / white arena edge.
