Holbrook claims there was negligence by the companies that designed, built, tested and kept track of the automated workforce, according to the Free Press.
The lawsuit claims that the robot's arm entered the section Wanda Holbrook was working in, taking her by surprise, and hit her head, crushing it against a hitch assembly the equipment was trying to place.
It happened at a company called Ventra Ionia which welds and stamps truck bumpers and trailer hitches.
The robot was from section 130 but was found in section 140, an area the lawsuit said that it should not have entered.
Named in the suit are:
Lincoln Electric Co. based in Ohio
Flex-N-Gate based in Delaware
Prodomax Automation based in Canada
FANUC America Corp based in Rochester Hills, Michigan
Nachi Robotic Systems based in Novi, Michigan.
The company where the accident happened, Ventra Ionia, was not named in the suit.
