The scout has some pre-programmed routines that are activated by receiving a message from the RCX or the IR tower. I listed them in a post to this group, I think the thread was something like "RCX VS the Scout". What I found was that the scout will (...) (26 years ago, 14-Oct-99, to lugnet.robotics)

| | Rotaion Sensor Sampling Speed?

Hi all, I'm putting together a mazebot for Mindfest, and ran into a bit of a funny with the rotation sensor. I THINK it has to do with the sample speed, but I'm not positive. I'm using pbFORTH and sampling the rotation sensor in a tight loop. The (...) (26 years ago, 14-Oct-99, to lugnet.robotics)

That is the same thing, except much easier. Plus we save donut money. However, we'd have to look at the effect of 7 volts reverse bias on the motor LED's.
