| | | | (...) This is actually very interesting. I guess one way to do it is to use the 'always turn left (or right)' technique to find the way from start to finish with the first go at the maze, recording the (x,y) position of each turn and to save space, (...)

Using two rotation sensors could certainly work, but that takes two RCX inputs, leaving me only one light sensor for line following (OK most of the time) and detecting & describing junctions (rather more difficult with a single light (...)

While this is a good "brute force" method of mapping a maze, you'll be saving, and trying to use quite a bit of information that you don't need. Assuming you can identify (...)

Agreed. although if we start running mazes with loops (like Alegomazer did) I think mapping, physically, the maze will likely be needed - if for no other reason than to know when you've closed a loop.
