I'm not entering so I have no official say.
We allowed ext. power for project x 'cause, well, the 'bots didn't move.
IIRC, I noticed in the vid for monkey bars that one was using ext. power. but
then there should have been no chance that bots would get entangled...
So I think it should come to the 'rule' that ext power is good only if it's
guaranteed that it won't foul other 'bots.
THat means, much like Chris and Steve's factory 'bot, if it doesn't move, then
is okay. If it does, then not so much.
But then you might run into a problem like when Trev had the bridge 'bot with
the little scooter with the long RCX wires trailing behind on the middle table
that might foul other 'bots--if external power cords aren't allowed due the the
chance of fouling up competitors 'bots, what's the ruling on ROV's running off
the RCX, trailing long 'Exploration Mars' motor wires behind them?
Ooooh, the mind reels just thinking about it.
