Jeez, I'm having some difficulty compiling all of these ideas into my mind.
My theory lies with the hexagon field and a ziggurat shape center.
Somehow IR beacon(s) are going to allow a robot to guide itself to a scoring opportunity or to a prominent location on the field.
I'm having problems with the teams or no teams issue. I don't think FIRST will easily abandon alliances. However, unless a large field is invented, having six robots on the playing field at once could be problematic. I foresee mass destruction if the competition is as aggressive as last year.
