Twendy-One, the bedside nurse-bot, has soft fingertips nimble enough to delicately grip a drinking straw and arms with the strength to lift an adult out of bed. The machine is designed to help Japan's growing population of frail and elderly continue to live in their own homes. Researchers at Waseda University in Tokyo say Twendy-One can clean floors, carry patients, and even bring them breakfast in bed. The next task is refining the software and mechanics to allow it to safely respond to commands to do things like fetch medication or refreshments. But start saving now: Scientists expect Twendy-One to go on sale within a decade for about $200,000.
