No, I've still not made a LIDAR webpage for the site (I'm also considering a line-following page - Steve, I know you wanted to do that at one time on your site). But a few posts on LUGNET caught my eye: (URL) ran it through (URL) for a (...) (19 years ago, 27-Sep-05, to lugnet.org.us.laflrc)

It was a bit slower than the bot that finished second. However, after learning the (...) (19 years ago, 27-Sep-05, to lugnet.org.us.laflrc)

(...) The advantage of working with Ben. We once had a racecourse set up so that the first car through a "canyon" collapsed the wall over the second car. Fun. I figure if it only pushes 2-3 balls, it has to make a lap every 2-3 seconds to handle the (...) (19 years ago, 27-Sep-05, to lugnet.org.us.laflrc)

(...) Wow, great minds think alike... when I saw that post, and another one about a 3vil monorail (sorry I can't find the post anymore) I immediately thought about GBCs. I mentioned the idea of a GBC monorail to Steve last week, but after trying (...) (19 years ago, 27-Sep-05, to lugnet.org.us.laflrc)

Here's a picture with the maze results: (URL) the web site has a 9mb video which includes the winning robot running the maze. (...) (19 years ago, 27-Sep-05, to lugnet.org.us.laflrc)

(...) 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, (...)

(...) 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 (...)

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. 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.

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)

(...) 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)
