Hi, I'm writing a Visual C++ program to control simultaneously 2 RCX (using Spirit.ocx). I'd need to know when a task is ended to start the download of a new task (I'd need a kind of TaskDone event). Is there a way to do this? Does anybody have (...) (26 years ago, 21-Oct-99, to lugnet.robotics.rcx)

I know that some of you use pneumatics for yuor robots. How do you do that?

I have found one so far, but the valves are very pricy. But (...) (26 years ago, 21-Oct-99, to lugnet.robotics)
