The tests involved a robot arm weighing 14kg and a 1.1m reach that was equipped with a variety of bladed household tools including a steak knife, kitchen knife, scissors and screwdriver.

The robot arm was programmed to use the bladed tools to stab and cut a silicone lump, a leg from a dead pig and the arm of a human volunteer.
Striking, stabbing and puncturing tests with the safety system turned off were performed on the silicone and pig leg. Deep cuts resulted in most cases that, the researchers said, could prove to be “lethal” if inflicted on a living subject.
