content: According to the lawsuit, Holbrook, a journeyman technician, was performing routine maintenance on one of the robots on the trailer hitch assembly line when the unit unexpectedly activated and attempted to load a part into the unit being repaired, crushing Holbrook's head. Now Holbrook's estate is suing the three companies that built the robots (Fanuc America, Nachi Robotic, and Lincoln Electric) for failing to design adequate safeguards and protections into the robots. They're also suing two other companies that installed and maintained the unit (Flex-N-Gate, Prodomax) for failing to prevent an accident they say would have been avoided had safety been a higher priority.  I think they are saying there that they didn't have the ability to do so... If that is the case that is fucked up. I'm a millwright assistant and I've never seen something you couldn't lock out.
