(...) Well i havent tried anything myself but i think the most effective way would be to use a tire in contact with the lens. You've probably tried that already, but it was the first thing that came to mind. hope it helps. (25 years ago, 4-Nov-00, to lugnet.robotics)

Hi, I wonder if anybody has succeeded in building a motorized focus controller for the Vision Command cam. So far I have tried several ideas but none was very effective. I am looking for better ideas. Jan (25 years ago, 4-Nov-00, to lugnet.robotics)

In NQC you count by adding 1 to a variable like this: int counter; counter += 1 But it's hard to know *how much* you have counted; however, you can build a little program to (say) flash a light when you reach a certain count. I have spent about 4 (...) (25 years ago, 2-Nov-00, to lugnet.robotics)
