...and you are going to share this great sensor, aren't you? :) But of course! If you take a look at www.borg.com/~pinkmice you'll get an idea of the lengths to which I go to build stuff! (apologies in advance for the size of the pictures - I know (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

I have been experimenting, on and off, with a "better light sensor" for the RCX. No offense meant to Lego or any of the more purist Legoists, but I indulge myself in designing various other sensors for RCX use. In the course of that indulgence, I (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

I have more detailed photos of the assembly if you would like to reproduce my results: (URL) is essentially two turntables fastened together with angle brackets. It uses a touch sensor to home the yaw, and a rotation sensor to control the pitch. (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

(...) Actually, I went home and tried it, and this seems to be the major problem. Even for objects that were totally green or blue, the value with the red filter over the end of the sensor was consistantly higher than the blue or green filtered (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

I tried this a little when I first made my robot using the red bat wings that come with the set, and I couldn't get a good image through one of them. One of the big problems is that the sensor is mostly infrared, with some red sensitivity. I haven't (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

I'd strongly recommend the Code Pilot set. ((URL) 1,263 pieces, including TWO clutch gears, lots of other gears, a motor, two touch sensors, and cables. Normal retail is about $150 US, but Shop@Home had it last Christmas as a special for $100. Doug (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

(...) The Technic Space Shuttle 8480 is a superb parts package, so good in fact that I bought two of them in a sale. Perhaps the down side for Mindstorms folks is that the large motor supplied is an old style 9V one. The smaller one is a (...) (25 years ago, 28-Sep-00, to lugnet.robotics)

Hello everybody, I just signed on this list and I am completely new to Lego-based robotics -- but I am quite excited about it all! If I had only had this when I was a kid! (And had more free time!) Anyway, I do have an opening question. I've visited (...) (25 years ago, 27-Sep-00, to lugnet.robotics)

That a great idea. But how do you control the pressure, as it is pumping all the time. I suppose you could vent it until a minute before you intend to use the compressed air... I like the Roverbot because it moves slowly and has a lot of torque. (...) (25 years ago, 27-Sep-00, to lugnet.robotics)
