This company tames killer robots

A seven-foot-tall robot arm moves in a blur, carrying a piece of metal about the size of a bowling ball from one workbench to another at superhuman speed. But when a human worker reaches for the piece, the robot goes into slow motion and then eventually stops. The machine and the young man are assembling a car suspension together. To anyone familiar with industrial robots, this seems insane. Industrial robots are capable of killing a person.
