David and Goliath
Probably the most striking thing about this years' competition in Tokyo was the huge, and I mean HUGE entry that seemed to just toy with the other Robo-One competitors. Here's a couple of match photos (click on any of the images for an expanded view)-
The robots on the left in both photos weigh about 2 kg (4.4 lb.) The massive guy on the right tipped the scales at 8 kg (17.6 lb.) In a typical match he would position himself so that the smaller robot was to his side and slightly in front of him. Then he would squat down a bit, and use his arm to swat the other robot like a fly. It worked surprisingly well, and a lot of the competitors went flying head over heels, sometimes right out of the ring.
Most of the opponents tried frontal attacks. Unfortunately that made almost no impression on the huge robot. It might move slightly, or even gentlely tip a little, but by and large it stood its ground. After watching some of the earlier matches, one of the competitors figured out that the huge robot might be more vulnerable from the rear. It snuck around behind, and then did a flip hitting the huge robot pretty much in the butt. That did the trick, at least for one point in this particular match.
There was a lot of discussion about the robot's size and weight. Some people felt that it shouldn't be able to compete at all since there was a tremendous size gap. They were really mis-matched to say the least. During the wrap-up discussions the officials kicked around the idea of introducing weight/height classifications for the next competition.
