Steve, I think your post was meant to read like this: (...) I was working with this same idea yesterday, but the problem is this will not give you correct information when you are turning. Does anyone have a suggestion about how to do that? I want (...) (25 years ago, 30-Aug-99, to lugnet.robotics)

It sounds like you guys are trying to re-invent the adder/subtractor system. Check out (URL) for some designs using this. In an adder/subtractor you have two motors, A and B. The wheels are then run through a mechanical linkage such that one wheel (...) (25 years ago, 31-Aug-99, to lugnet.robotics)

I agree that the adder/subtractor is the way to go (at least for now) if you want any semblance of accuracy in your robots - I even started the thread on what was the best design for the a/s (remember LDraw?) from which this branched out. (I hope (...) (25 years ago, 31-Aug-99, to lugnet.robotics)

I had written: (...) Yeah, I suppose you are right. I think the only advantage to this scheme is that you can use a micro motor to power the clutch mechanism to that you don't tie up a full size motor. Also if you are running out of motor outputs, (...) (25 years ago, 2-Sep-99, to lugnet.robotics)
