Alexander, Thanks for the differential/pole-reverser idea. Based on your description, I was able to get a prototype running very rapidly! I'm still seeking a clean more mechanical version, but this certainly will work for now. Along the lines of a (...) (18 years ago, 23-Mar-07, to lugnet.technic, lugnet.robotics)

Do we loose points for melting the eggs? At any rate, it makes the foil stay on better. ;-) --Peter (18 years ago, 22-Mar-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

(...) Will, If you do manage to combine RCX & NXT, I expect it will look mashed-up, but unlike all the other stuff at BF, this is not a how-does-it-look competition. No matter how it looks, I'm sure people will cheer for robots that try to give them (...) (18 years ago, 21-Mar-07, to lugnet.events.brickfest, lugnet.robotics)

It will likely be horrible ugly, and exhibit questional operational effectiveness, but fame and (...) (18 years ago, 21-Mar-07, to lugnet.events.brickfest, lugnet.robotics, FTX)

I think one way to do this uses a differential (URL) and a pole reverser (URL). I don't have a picture to hand but the idea is simple. One side of the differential is connected to the low torque "input axle". The differential housing is connected to (...) (18 years ago, 21-Mar-07, to lugnet.technic, lugnet.robotics)

(...) A torque amplifier is EXACTLY what I need; thank you! Now I just need to figureout how to build one. Google has a few pix, two lego ones actually. I hope this will get me where I need to go! Thanks for the help, Rafe (18 years ago, 21-Mar-07, to lugnet.technic, lugnet.robotics)

(...) The original Mindstorms rotation sensor turns very easily - I think that three stud-balls of torque would be plenty to turn it. The more recent NXT stuff is another matter - I don't have a NXT system so I have no clue as to the problems of (...) (18 years ago, 21-Mar-07, to lugnet.robotics)

More information about your application would be helpful. The first thought that jumps to mind is "Use a more powerful motor. Duh!". So there must be something that I am missing. There must be some reason you need to use the puny motor. Maybe you (...) (18 years ago, 20-Mar-07, to lugnet.technic, lugnet.robotics)
