(...) 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)

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)

(...) 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)
