A bed that converts to a wheelchair, and a robot for hospital use were two of the cool things I saw at Panasonic Center in Tokyo.
Elderly people sometimes need help getting in and out of bed. This bed converts to a wheelchair for great mobility and independence. It's also got a built-in LCD screen and medical sensors to monitor health.
