I mentioned the following solution at BrickFest, but I'll post it here again:
If you were to combine the Canadian pipe and the US pipe you have, another
solution is to have the 'correct path' be all black Canadian PVC, and all the
'wrong' paths be white US PVC. (Joints can be either colour, and should be
ignored.)
Of course this method doesn't help a robot try to get back to the one true path,
( the Canadian one :-) but a robot will always know where it is. An added bonus
is that SH will have to admit that the Canadian path is the one true path in
order to even have a chance at winning :-)
