Check out this great story of robot rescue, recovery, and wRestling from NYC Resistor:
A friend recently acquired a set of PUMA 260 / RP Automation robot arms and asked for some assistance in getting them running again.
Unfortunately they had been removed from their previous occupation with a set of wire-cutters. Some wires were labeled, most were not. But after a few weekends with a multimeter and some oscilloscope work, we have it running again. Read on for how to bring these arms back to life….
