I don't think computers are a valid comparison, computer wiring operates in an enclosed environment that is not subject to many of the hazards a robot's is. I imagine it is very rare for computers to have their wires caught in roller chain, for example. In fact, as far as I am aware, the only moving parts in a computer that are not fully enclosed are the fans, and they generally have shields on them and are usually made of non-conductive materials.
