| (...) hi Steve, I think the problem is not exactly the same. The lego technic motors run always at the same speed so you need to use that kind of schema for speed control in robots. The train motors are different, they have a speed proportional to (...) (18 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)

| I do think Steve is on the right track here. The train regulator varies the voltage, but the RCX output can't. So you are left with managing (nominally) 9v pulses. But there is another solution. You could add a DCC decoder to your train motor, and (...) (18 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)

But you need to do a bit more if you're using the RCX. We used that scheme when we (...) (18 years ago, 29-Dec-05, to lugnet.robotics.rcx.legos)
