(...) 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)

I hate to bring this to the group, but I'm puzzled. I *finally* got over procrastinating about biting the NQC bullet ... but the following program gives me "parse errors" on lines 8 (repeat 10) and 19 (the penultimate "]". Help! Where have I gone (...) (25 years ago, 27-Sep-00, to lugnet.robotics)

In theory, yes I believe it could be done, however I would be concerned that a 1x2 filter would be so thick as to distort the image drastically... better to take a sheet of transparency material and print a red, green and blue spot and attach it (...) (25 years ago, 27-Sep-00, to lugnet.robotics)
