Jag redan såg den, jag läser lugnet.loc.se :-)

No, not if you do everything in sequence.
I'd try this first, because it is simpler.

Then it is always multitasking, one task on each RCX.

You can make one task for each motor of the robot.
Then have a variable for commands to this task
(write a value to give it's target position)
and one variable that tell's when it is there/where it is,
so that your main task can wait.
This way you can run start all motors at once
and your robot will be faster.
With two RCX maybe tasks for communication are also good.

| Thanks for the replies, and for the sample programs. I'll try them out soon. I'm building a robotic arm (that's why I chose to reply to this message, not the other, later ones) that I plan to program in NQC. It does not need multitasking to work, or (...)
