Hello !
Some of us are looking for new Lego-challenges. So, I created this one,
which is called : "the Labyrinthus challenge".
"The goal is to build a robot which could enter into a labyrinth (made
of black tape on white floor or so) and find it's way. There is a light
beacon somewhere in the lab : the robot have to find the light beacon.
When the robot got the light beacon, he must exit the maze, from where
he came from. (That is, from the entrance)"
You'll find all details at
http://users.swing.be/philippe.jadin/labchallenge.htm
Be warned that it's probably very hard to complete (I didn't try yet),
and that my english is somewhat "poor" : I'll try to answer any
questions about the rules (if it's not clear enough), and if I
understand
what you mean (-:
Voilà, I hope someone will be reckless enough to try this...

P.S. Have a look at some new things I've made : the printer and the
realtime scanner. Goto :

| Got it figured out. Using the principles of right handed recursion, you can have the robot follow the right wall and it will eventually get to the light and also get out of the maze again. Incidentally, right handed recursion will get you out of any (...) (25 years ago, 13-Sep-99, to lugnet.robotics)

| (...) Yes, unfortunately the current firmware implementation from LEGO doesn't have a call stack, so you can not build recursive routines. :-( On the other hand I can imagine labyrinths where that bot would never be able to do anything out of them.

| Hi, This sounds like a great challenge! One quick question, is the square containing the light beacon marked in any way? Perhaps a different color floor for that square. It would make goal determination much easier. Or is part of the challenge (...) (25 years ago, 13-Sep-99, to lugnet.robotics)
