Well, then I guess I need to build my own rotation sensor using a "Potmeter"
(variable resistor) because I need a real angle, actually I need an angle
per time value. Is this is possible?
I saw something about this on a website in the mindstorms ring, using a 470
ohm resistor in series with a variable resistor of about 1M ohm.
Did someone ever tried to balance a long broom on his hand or finger? I'm
creating a car that does just that using fuzzy logic...

| (...) So long as your software remembers to count the revolutions, it's surely very simple to gear the Lego sensor to get a real angle... however for your idea below, you might need much too much gearing! (...) You shouldn't need fuzzy logic to do (...) (26 years ago, 28-Mar-99, to lugnet.robotics)
