Hello, I have inherited a hand-me-down RIS kit with a functional RCX unit that I would like to learn to use and put to a purpose. I would like to build a system whereas the RCX is setup to press buttons on controllers (think remote control units) to (...) (14 years ago, 29-Jan-10, to lugnet.robotics.rcx.legos)
