I wasn't a participant, but three of my students were. Check out the videos:
Twistys very nearly beat Blooper Reel in the first battle.
In the first round against Double Feature, we disabled it but managed to lose our own mobility.
Finally, a burned-out electronic speed controller lost us the match against Double Feature.
All in all, a great competition. The students were great sports, built an excellent robot, and everyone had a ball.
