(...) A straight tri-wheel like that can't climb anything higher than half it's height though. If you are really after something that'll climb TALL steps, then it has to have something high up at the front to grab the top of the step with. Even a (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

Ok, so, the complete description.... It's not really a competition, but a project for students in my university... We have to build a bot with LEGO mindstorms... This bot has to be able to follow a line on a ground made in steel. This line goes (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

(...) Oh - that's a pain. (...) Well, I guess it depends on how rough the terrain in general is. If it's a flat, smooth surface with just one 5cm hole - then practically any vehicle with (say) 6 wheels will drive across it like it wasn't there. (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

What would happen if you took a wire from a sensor port on one rcx and connected it to a motor output on another rcx. Would this be a viable way to communicate with 2 rcx's if they could not be position for IR communication? My thought was that you (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

Thanks, Yes, it's the maximum dimensions... We have already seen the shrimp and we think to build something like that (maybe also with tri-star wheels)... But if somebody find a better solution, because we don't know the comportement of the shrimp (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

The frequency of the RCX's IR does not change at all: " The RCX uses a 38kHz carrier, which is pretty typical for TV remotes. As for the sampling rate, the RCX runs at 2400 bps, which makes each bit approx 417us " (URL) think the only way you could (...) (23 years ago, 28-Sep-02, to lugnet.robotics.rcx.legos)

(...) Is that the *initial* dimensions - or the *maximum* dimensions? If it's just one of those things like "the robot must start off in a box no bigger than 30x60x30" - then it can just fold itself up into that space when they are doing the (...) (23 years ago, 28-Sep-02, to lugnet.robotics)

Vincent, (...) Without knowing the limitations of your resources, I would vote for a legged vehicle. You can make if large enough that even if a leg did go in the hole it wouldn't fall in or get stuck, you could make it with as many legs as you like (...)
