Factory robots have been killing people for decades now. This particular incident seems to have resulted from a failure to lock out the robots in the adjacent work cells, which should have been SOP but apparently wasn't. If you're in the work envelope of an industrial robot, it should be completely powered off. This is one of those basic safety procedures like "assume all glassware is hot" and "don't unkink a hydraulic hose".
