A Swedish company Bioservo now sells a robotic glove called Ironhand. This glove boosts the grip strength of a 30-year-old man by a factor of five. It activates by the "intention" motion of the wearer. Power comes from a back or hip pack. Already used by General Motors, it sells for $6500. Remember, the Paris Fire Brigade used a robot for interior firefighting at Notre Dame Cathedral. The U.S. Army is developing robots that can climb hills and stairs.
