This picture taken on February 23, 2015 shows a polar bear robot "Robear" lifting a woman for a demonstration in Nagoya, central Japan. The "Robear", developed by Riken Institute and Sumitomo Riko, has a polar cub-like face with big doey eyes, but packs enough power to transfer frail patients from a wheelchair to a bed or a bath. A historically low birth rate and ever-increasing life expectancy means Japan's population of elderly people is growing, while the pool of youngsters to look after them is shrinking.
