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 (...) (17 years ago, 3-Oct-08, to lugnet.robotics)

Here is the finished frame. (URL) you look at the other pictures in the photostream for the ship (yeah, it's a spaceship) you'll see the paneling on the frame and a mockup of what the paneling looked like on the ship before i had a frame. The (...) (17 years ago, 2-Oct-08, to lugnet.robotics)

(...) The arc in question only covers 75degrees (5 panels, the first starting at a 15 degree angle). i managed to make it effectively with the suggestion of triangles out of technic pieces. triangles made of two 1X6 technic bricks and one 1X2 brick (...) (17 years ago, 2-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? (17 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 (...) (17 years ago, 1-Oct-08, to lugnet.robotics)

(...) And 12, and 14, and 20, and 36, and then there's that worm-gear. And that's not even getting into the old-style gears, or that odd 4-tooth knob gear (though that's really only useful with other 4-tooth knob gears, so it doesn't really help (...) (17 years ago, 27-Sep-08, to lugnet.robotics)
