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)

(...) How much torque do I need to drive the rotation sensor? This was my first plan of action, but I was limited because I don't have a rotation sensor other than the NXT motors themselves! From a purist point of view, I would really like a (...) (18 years ago, 20-Mar-07, to lugnet.robotics)

(...) ... (...) So use a rotation sensor to sense the position of the weak input - and use a NXT motor to track that position and drive all of the gears. You can change the ratio of the input angle to the NXT motor's angle in software and thereby (...) (18 years ago, 20-Mar-07, to lugnet.robotics)

I have a gear train that is driven by a very weak input, very small torque. There are some places in the gear train where I have some worm gears driving some 'regualr' gears. As I go along the gear train, I boost the output as much as I can with (...) (18 years ago, 20-Mar-07, to lugnet.technic, lugnet.robotics)
