Acutally Ken, I belive that it would be very easy to pin a bot in such a manner that it could never get out.

Even a bot with only a two drill motor drive train that was shut down could pretty easily do it. All you have to do is get your wheels perpendicular to thiers (imagine a 'T'). That way, the motors free wheeling have no effect on it, the pinned bot has to have the power to either slip the pinning wheels sidways (which depends on the wheel type and number of them) or otherwise tip the bot. The pinned bot would have no room to turn sideways, so unless it can crab, it's only choice is to try to push the pinning 'bot out of the way.

I've tried pushing my teams bot from the side. It only has two wheels powered by drill motors. Unless I pushed at the corners or fairly high up, she didnt budge an inch. A four wheel drive would be just about impossible for me to have moved, and I have the benifet of arms and and extra 30 pounds of weight on a FIRST bot.

I think this situation could happen.
