[petek]

Maybe I'm looking at this too simplistically, but rather than limit engineering designs, I would prefer that FIRST instruct referees to penalize a team which, while in the process of pushing on another robot, causes it to fall over. This would apply to any shape of robot and would not penalize the "ramp bot" unless it was driving into the tippee. It would make it a penalty to push a robot up the side of a wedge (e.g. this year's goals) until it tipped over. This would not penalize a robot if the two got tangled up and, while trying to get un-tangled, one of them tipped over, unless the tipper was pushing against the tippee. Also, it would not penalize a robot if the tippee was doing the pushing or ran into the side of the tipper accidentally.

Am I missing something?
