During the Silicon Valley Regional, the defense that 604 played against 254 in the finals was surprisingly effective. In fact, 254 was being pushed around at its side and couldn't break free. I think their light weight prevents them from having the necessary traction to break the friction between the bumpers. If 604's alliance was more effective at scoring, 254's alliance, which is the first seed, may have lost the competition

This leads me to speculate. Would a defensive robot be effective if it has a powerful enough drive train with enough traction and gear reduction and very high friction cloth for bumpers. If it pushes another robot at its side, it may be effective in preventing the other robot from maneuvering. Of course, this is just a thought, and I haven't done any math to substantiate this speculation, so I may be completely wrong.
