Hey folks, rtlToronto15: In light of someone calling rtl15 sumo on pipes, I was thinking about turning rtl15 into an actual nonlinear path. Meaning, instead of having only one true path, having the other joints forming an entire grid. Every joint (...) (21 years ago, 25-Aug-03, to lugnet.org.ca.rtltoronto)

(...) Would this mean then that robots would need to be able to lift guidewheels to clear branching points? That's how I read what you say about "grid", that there are tee/Y/cross pipe parts and not just bends. (21 years ago, 25-Aug-03, to lugnet.org.ca.rtltoronto)

Calum, lets just leave it at a "maze" and mark a correct path. with all the T's and Y's they could very well lead to a finish, but we have one "proper way" lets not encourage the multi-path. if a multi path works out in the building of the (...)

(...) I like it. The original thought was that before each joint there would be 1 strip or 2 1 strip means 'go left' (as left as left can be in a 3 d grid), or 2 stripes means go right (again, same).

So Calum you are suggesting that the shortest path would be the marked path, but if a robot goofs up, and turns the wrong way, it can continue, and take a longer, route that will still lead it to the critical path.
