It's interesting you mention this. I have also started to use RJ11 and RJ45 connectors in my constructions. It is a neat and compact way of routing 2, 4, 6, or 8 wires around. I am working out the most neat and compact way of stuffing them into a (...) (27 years ago, 6-Oct-99, to lugnet.robotics, lugnet.robotics.rcx)

G'Day If you are willing to use 'non-pure Lego' parts, then Radio Shack has a telephone cord 'detangler' that plugs into standard RJ-11 jacks, has 4 conductors, and 360 degree motion. Works rather well, esp. with some contact enhancer for a cleaner (...) (27 years ago, 5-Oct-99, to lugnet.robotics, lugnet.robotics.rcx)

We are planning on solving a physical maze (ie cardboard or plywood.) The plan is to use LegOS to allow C (NQC) capabilities. We haven't started on the physical part yet; instead we are concentrating on developing a working algorithm for solving (...) (27 years ago, 4-Oct-99, to lugnet.robotics.rcx)

Does anyone know anything about the RCX being used to solve maze problems? I am doing this for a school project, and I wanted to know if there is any information out there about it. Thanks, Eric (27 years ago, 3-Oct-99, to lugnet.robotics.rcx)
