(...) There are various geometries have been implemented in Lego bricks for this. Here is one example: (URL) searching Google for "Lego adder subtractor" for others. (21 years ago, 2-Jun-05, to lugnet.robotics.rcx.legos)

(...) Do you mean robot hands? If so, try the one from my robot: (URL) It's actuated with pneumatics at the moment but the two 24mm pulleys have bevel gears linking them, to keep the fingers synchronised, so you could use a motor and low gearing to (...)

(...) From something I read 12 years ago for my university project (a Lego robot of course, but pre-RCX), I think it required differential equations (ugh!). Probably a bit too memory-hungry for an RCX. Perhaps you could use the PC's computing power (...) (21 years ago, 26-May-05, to lugnet.robotics.rcx.legos)

Thanks Thomas for your idea. The matter is that I was thinking of using angle sensors in order to calculate the number of the turns that each wheel has driven (I am talking for a robot with 2 wheels). I think that some advanced maths are required (...) (21 years ago, 26-May-05, to lugnet.robotics.rcx.legos)
