This is mostly being played as a joke around the intertubes but obviously deadly accidents are a real issue in any industrial setting:
A Swedish company has been fined 25,000 kronor ($3,000) after a malfunctioning robot attacked and almost killed one of its workers at a factory north of Stockholm. Public prosecutor Leif Johansson mulled pressing charges against the firm but eventually opted to settle for a fine. “I’ve never heard of a robot attacking somebody like this,” he told news agency TT.
Notwithstanding Johansson’s lack of previous knowledge, but this sort of thing has happened before. Japan, where they have the most robots, is the world’s leader in robot-related accidents and even former Prime Minister Koizumi has been attacked. But this has happened in the United States and U.K. as well. On net, however, the evidence is pretty clear that the advance of robotics is making industrial accidents less common rather than more common if only because it involves fewer human beings doing work in dangerous industrial settings.
