I have been a LEGO fan since a young lad. For the past 4 odd years I have got back into it and collected a large amount. Every time I posted anything about LEGO and robotics I was ridiculed by my favorite forum's posters. I have built bridges, cantilever, suspension, arch, and beam. Cranes of all types. My best a 1.3meter span, 2meter height tower crane. After a 3 week build the project tumbled in an explosion of plastic as I pushed its weight limit to far. Robots of all sorts and the usual artistic space ships and the like. But now I found a great project that some here on the forum may like. http://www.newscientist.com/article/dn19848-toydeforce-inside-the-steampunk-lego-lab.html I am going to try to build it to. There are no plans available but the images and math is there. I hope that there are other LEGO fans here on sciforums that would like to share their experience and technical builds.
