Actually, now that I think about it, BrickOS might be able to run assembly language (...) (21 years ago, 26-Nov-03, to lugnet.robotics.rcx.robolab, FTX)

| Having investigated rotations sensors thoroughly, I conclude they have some serious design flaws. Most notably, some samples taken during voltage transitions can be impossible to differentiate from samples at entirely different rotational positions. (...)

The gearshift is activated by a motor controlled by RCX, gearing (...) (21 years ago, 26-Nov-03, to lugnet.robotics.rcx)

| (...) Yes, thank you - you explained it very well. The day after posting the question, I realized a differential would solve the problem... but you stated the solution far more clearly than I had thought of it. Now, of course, I'm trying to think (...) (21 years ago, 26-Nov-03, to lugnet.robotics.rcx)

| (...) Yes, that was the problem Brian was having. And, because the LEGO motors are so efficent, they work really well as generators. So, if you hook two together, and try to turn 1 and stop the other, you will have problems. I'm not sure I explained (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)
| | | | | Re: Weird downloading error
|
| Just some general ideas. If you're not using the firmdl or lejosfirmdl that came with lejos, try using one of those. Some versions of some downloaders have trouble with the lejos firmware. If you haven't tried fresh batteries in your RCX, try that. (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx.java)

| (...) I'm just thinking out loud here, but it seems that the problem with the two middle motors is that they are wired together. So even if the RCX is told to float the motor output, both motors will want to turn together. If one turns, it will act (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)

And I've also used four motors (two on each side) to drive six wheels (two on the right, two on the left, and (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)
