I don't see an answer to navigating an infinitely variable environment, which seems to mean that there's not going to be a general rule for robot navigation. I know that's hardly staggering, but it's always nice to show there's no more general case, even for the environments that theoretically CAN be navigated. -- Anniepoo Need loco motors? http://www.idiom.com/~anniepoo/depot/motors.html
