well I guess we could see how it goes, then maybe drop AM first if theres problems.
If sombody built a walker there could be a heavy spinning bar or disk in the arena, even with the wheeled spinners it wouldnt be nice if one of them picked up a signal when sombody had there hand in the arena.

Arenas going to be steel framed and steel floored.
Did anyone have any probs usin 40meg at robochallenge?
