As Japan greys, who will look after the elderly? Maybe one day their aging children -- in robot suits -- if technology under development comes out of the laboratory and into the home. Here is an air-pressure robot suit that makes it easier to lift an elderly person out of a wheelchair or bed, suit looks clunky, takes 10 minutes to put on, weighs thirty kilos (66 pounds) and has blinking lights and wires reminiscent of a robot in a sci-fi movie. It allows the wearer to lift a person as heavy as 100 kilos as if they were carrying only half that weight.
