For those robots with a long arm, I wonder how it will work driving around with the arm sticking almost straight up? There's the fun thing about the CG being relatively high, and the robot wanting to fall over during sudden maneuvers...and you have to watch out for minibot towers...and other robots with stuff sticking out up high. Especially if you're possessing a game piece.

I'm thinking our decision to use mostly all locally available materials, and a few bolts and rivets to hold it all together, might be a good decision.
