Japanese researchers have created a robot nurse that can lift elderly patients from wheelchairs and beds. It looks like a giant teddy bear. Riba, short for Robot for Interactive Body Assistance, was developed by the state-run Riken research center. Promoters are calling it the world's first robot to lift people in its arms.Riba can move patients weighing up to 134 pounds in its foam-padded paws and transfer them from beds to wheelchairs. Its cute face is designed to make the 400-pound robot less imposing. Riba can also recognize faces and voices and respond to voice commands. According to Riken, there are no plans for immediate commercialization, but it will be deployed to hospitals over the next five years.
