Paul, If you put a small lamp in serie with the motor , you can monitor the current drawn by thr motor through a lightsensor. The more current the more the light, there is only one thing you have less motorpower. Gretings, Rik "Paul Andrews" (...) (23 years ago, 7-Sep-01, to lugnet.robotics.rcx)

Hi, Dave In your NQC Guide, there is a text about this function "The default is to send data at 2400 baud using a 50% duty cycle on a 38kHz carrier.", how about other settings, for example, parity and stop bit, is it odd parity without stop bit?

You can enter the WORKSHOP 3D LEGO RCX Challenge - a robot competition to be held in Seattle on October 6th - even if you don't want to travel here. There will be a "code only" line-tracking event that anyone can enter. Build a "standard robot" at (...) (23 years ago, 7-Sep-01, to lugnet.robotics, lugnet.robotics.rcx)

| | New patch for remote and message

I made a new patch for remote control and standard firmware message communication, I defined three config constants in config.h: 1. CONF_REMOTE_CTRL: Remote control services, comment it if you don't use remote control. 2. CONF_MESSAGE: Standard (...) (23 years ago, 7-Sep-01, to lugnet.robotics.rcx.legos)

(...) 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)

(...) 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)
