| (...) 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)

| (...) 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)

| (...) Well, I've never actually tried running six motors directly from the RCX. However, I have used three motors to drive a sumo robot. 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)

| (...) ...I love understatment. sigh... (...) OK, in trying to implement this I've come to an interesting impasse. Calculations suggest that for a 4 lb sumobot with reasonable tires would "benefit" from six motors, three on each side (differential (...) (21 years ago, 25-Nov-03, to lugnet.robotics.rcx)
