“I talk to him all the time, and he responds to my voice, ”says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own. ”

　　The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.

　　“At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry, ”Beck says. “But it’s amazing how quickly we have given up that belief. ”

　　“Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds. ”

　　【文章大意】本文是一篇说明文。为了解决现在老人的孤独问题, 研究人员研究出一种机器狗, 和老人一起生活, 提高老人的生活质量。
