(...) Yes. I just got a rotation sensor. Trouble is that the motors could stop for a variety of reasons (like the robot isn't moving). That isn't the real reason though (I could always handle that in software). The real reason is that ever since I (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx)

(...) Yes. I found on article on using the battery voltage to determine the same thing, i.e. more current, less volts. To do it you need replacement firmware. I use leJOS (a Java VM), I'm one if the developers, so I could go in that way. I'm going (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx)

So you're in to Java and the RCX? If you're in to it deep then you might be interested in the Real Time Specification for Java (RTSJ) at: (URL) - Paul (23 years ago, 6-Sep-01, to lugnet.robotics.rcx.java)

So I don't know if this is heresy on a Lego web site but if you're interested in Java and RCX you'll probably find this interesting too: (URL) I have no affiliation with this company, I am a contributer to leJOS.

(...) Hi Paul, I was interested in doing the very same thing a while ago. It sure would save on sensors if the motors had their own feedback! I know (as you are probably aware also) that the current can be monitored using the cybermaster. I saw how (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx)

I assume you have already discarded the simple approach of using a rotation sensor and detecting that it has stopped rotating. (This gives you an odometer for free!) Or if you don't have a rotation sensor, you can use the half width six hole pulley (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx)

Hi, I'm still new to legOS, and the RIS come to that, and while looking for info on legOS came across both of these : (URL) seem to have different versions. Noga.de seems to have more up-to-date newsposts despite having an older version of legOS. (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx.legos)
