Hi! I have tried to get my old (old? It was the first one in Austria!) RCX 1.0 working again, but didn't succeed. After all these years, the firmware seems to be gone, it doesn't even run the on-board programs... I tried to install the original (...) (16 years ago, 22-Oct-08, to lugnet.robotics)

OK, so I got roped into going to a meeting of a fledgling Robotics League in Orange County, California. They invited me because one of the founders of the League knew I was into Lego. There were several FIRST and FLL coaches, mentors,and club (...) (16 years ago, 11-Oct-08, to lugnet.org.us, lugnet.edu, lugnet.robotics)

Hi all, I just upload two articles of three LEGO robots I've made, 2 RCX able to follow a light and a line, and one NXT to fight sumo. Right now I've just "clean" the code of the line follower, as soon as I'll make the other code available I'll post (...) (16 years ago, 3-Oct-08, to lugnet.robotics)

(...) Further measurements show that connector #3 is 22.5 degrees - this means you can use these to make a jointed 90 degree arc with 5 panels (the ends would be perpendicular to each other). Would this meet your design requirement? (16 years ago, 2-Oct-08, to lugnet.robotics)

(...) It doesn't need to be exact, just repeatable. I need to make an armature of 4 or 5 successive 15degree "turns" to support some panels that are making sort of a jointed arc. I'll give the technic pieces a try. Almost jumped for joy at Nick (...) (16 years ago, 1-Oct-08, to lugnet.robotics)
