| | Positioning with the RCX - a pragmatic approach

THE QUESTION ... ... how to determine and measure a position in a room? This question was raised several times in LUGNET (e.g. Kris Zabriskie) and caused some discussions. As it has been stated, this simple sounding task is not at all trivial and (...) (24 years ago, 3-Jan-01, to lugnet.robotics.rcx.nqc)

Thanks to everyone who helped out with my problem, it's much appreciated! The problem was not having the firmware loaded, which I was able to download to the RCX using the latest version of MacNQC. I had an earlier version of MacNQC which wasn't (...) (24 years ago, 2-Jan-01, to lugnet.robotics.rcx.nqc)

Is it possible to device a task that will keep a motor running for as long as a joystick button is pressed? Or do I have to write a prog. for my computer instead of one for the CM?
