What was I thinking of is radio controlled robot. All software stays on the PC. I've been looking for electronic devices used for planes or cars radio steering. The problem is that it would have to send back data from the tobot to the PC. Very (...) (24 years ago, 9-Feb-01, to lugnet.robotics)

Thanks. Just after I posted, I went for a browse on the official site, and found about 5-6 "real" walkers. Now I can keep working on mine, knowing that it's possible! Gordon (24 years ago, 9-Feb-01, to lugnet.robotics)

Hi all. Has anyone here managed to build a "real" 2-leg walker. What I mean by "real" is one that doesn't rely on a dragging tail, or sittnig on it's ass to walk, but actually transfers it's weight to one foot and takes a step with the other, then (...) (24 years ago, 9-Feb-01, to lugnet.robotics)

I agree with what was posted before that you might want to get some basics in programming first before moving onto mindstorms...

(...) Try the original software, then NQC, then others. For a start try Dave Baum's book Definite Guide to LEGO Mindstorms. If your library doesn't have it, there's some material on the web: (URL) Jürgen Stuber <stuber@loria.fr> (URL) (24 years ago, 8-Feb-01, to lugnet.robotics)

Probably the most significant thing about RIS 2.0 is that the IR 'tower' (...) (24 years ago, 8-Jan-01, to lugnet.robotics)
