Japan show provides glimpse of robots as future of rescue efforts

With a drone camera, a survivor is spotted in the rubble. A robot on tracks brings him water while rescuers in exoskeletons clear an escape route for an autonomous stretcher to take her to safety.

This is the futuristic vision on display at the Japan Mobility Show, aiming to exhibit how technology can help and sometimes replace humans in a country short of workers and no stranger to disasters.
