Tobias, 'multi-tasking' means that several tasks run simultaneously. For example, a robot arm could grab, lift and swivel, one after the other, as functions, or simultaneously, as tasks. Or, the RCX could play a tune and a walker could walk, one (...) (24 years ago, 5-Feb-01, to lugnet.robotics.rcx.nqc)

I've downloaded NQC, and got it running. I have been able to make the motors run, to make them run backwards, then forward, etc. However... I can't get the sensor thing to work right. I want to make a program for a robot that backs up and turns when (...) (24 years ago, 5-Feb-01, to lugnet.robotics.rcx.nqc)
