I have a pair of industrial robotic arms that allegedly came off a pcb assembly line. This evening, I tried one out for the first time. It works! I plugged everything in, hit the green run button, and the arm sprang to life (the poor thing thinks its still out on the factory floor). I was able to directly control the motion with the teach tool, but unfortunately, some of the buttons no longer work, so I may try to open it up and repair it. More likely, I’ll just forgo the teach tool altogether, and program it via the serial connection. I haven’t come up with any good projects for it yet, although I do want to try mounting the RepRap extruder on it.
