My former (just graduated) high school had a Battlebots IQ team. They put up a website , which details their robot, E2, and the competition. They did quite well, winning 6 in the double elimination format. I didn't participate in this, but I was involved in the Panasonic Creative Design Challenge, a robot competiton open to high school students in the State of New Jersey. I reccomend this competition to interested students, since I won a two grand scholarship that is going toward my EE degree.
