The population of the people over age 80 will be about 426 million in 2050,three times larger than that now. Such robots could be especially useful to patients with Alzheimer's disease(阿尔茨海默氏病).They can help with everyday activities from preparing food to reminding(提醒)the patients to take their medicine. They can also play games with patients to keep them active. Some have worried that care giving robots might reduce(减少)human interaction(互动) and cause more humans to lose their jobs. “But the aim is to support human care, not to take the place of it,” says Brian Scassellati. He has tested robots with different patients, and found that daily interaction with robots can help children with autism spectrum disorder(自闭症谱系障碍)improve social skills. As a field grows, scientists aim to.understand human-robot relationships better. Do robots offer advantages because they don't have feelings and don't give opinions? Will patients lose interest? “One thing is clear,”Scassellati says.“Robots can provide care for the customers and the need for that will increase in the future.” 1.
