No. The reason for doing that (using the electrical plate) is if you are running big trains that put a large load on the RCX, or (...) (19 years ago, 28-Sep-05, to lugnet.org.us.laflrc)

First, thought I'd visit this group to see what's up... Anyway, for the GBC--specifically the train portion--Few questions-- did you just connect an RCX to the track? did you use the 2x8 electrical plate to combine all outputs a la Mark Riley's (...)

(...) Nodes I haven't seen have a value of zero. Every time I [re]enter a node, I add 1 to the value that's currently there. If there's no right turn (I follow the right "wall"), I add 2. When the total is 4, you're done searching that node. So, (...) (19 years ago, 28-Sep-05, to lugnet.org.us.laflrc, lugnet.robotics)

(...) Yes, I'm sure that's it - you just *imagined* you maze-solver worked ;-). (...) Hmm. OK, that's got me confused. I *know* I'm storing more information than needed, but each node in the path only takes 2 bits? If those two bits encode the (...) (19 years ago, 28-Sep-05, to lugnet.org.us.laflrc, lugnet.robotics)

(...) I didn't read it. But if I had... (...) 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.

Brian, don't read this. (he's trying to work it out for himself...) :) (...) 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. 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 (...)

(...) 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, (...)
