I was reminded of this by this:
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.
Thinking he had cut off the power supply, the man approached the robot with no sense of trepidation.
But the robot suddenly came to life and grabbed a tight hold of the victim’s head. The man succeeded in defending himself but not before suffering serious injuries.
