(...) Well... there's two things here, and Steve solution actually addresses them both. Do you actually need a continual series of states, and the "weight" of the thing on the end of the beam, or just know if something *is* on the end of the beam? (...)

(...) Don't mess with colors. Just use a gradient. You'll have a mostly linear set of values. With my black & white studs, there are also several shades of gray in between (like a little black & mostly white...) (...) no. :) Steve (18 years ago, 20-Jan-07, to lugnet.robotics.nxt)

(...) "It's foolproof!" (...) This sounds like a good idea. I'm thinking I'm going to have to work out a sequence of more than just two shades, but that's what weekends are for, right? So, if I could make of sequence of colors that have increasing (...) (18 years ago, 20-Jan-07, to lugnet.robotics.nxt)

(...) Easy. A light sensor. Point the sensor at a disk that's shaded from white to black. I've used that to detect the distance a robot is from a wall (wall following), using just a black & a white dot (1x1) which are moved in front of the sensor. (...)

Hi all, I am working on a "project" where I want to measure some reasonably small rotations, things on the order of +/- 10 degrees or less. Just to make it hard, the force acting on the thing being rotated is small, like, completely hypothetically, (...) (18 years ago, 20-Jan-07, to lugnet.robotics.nxt)

(...) Very cool Steve... I can also atest the turn radius will stink since I did the same mod to the red tow truck set last year. You said you are using old style light sensors...Interfacing them to the NXT with the converter cables I assume?
