    Researchers are placing robotic dogs(机器狗) in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study about the influence of robotic dogs on old people's depression, physical activity, and satisfaction. "No one will argue that an older person is better off being more active, challenged, or stimulated(刺激), "Edwards points out. "The problem is how we promote(使……成为现实) that, especially for those without friends or help. A robotic dog could be a solution. "

    In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.

    "I talk to him all the time, and he responds(回应) 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. "

    "For your generation to live in      better world, there is so much more our generation can do, "Zuckerberg wrote." Today your mother and I are committed to spending our lives doing our small part to help solve these challenges. "The couple     (donate) nearly all of their Facebook stock to the cause." We will give 99% of our Facebook shares—currently about 45 billion—to advance this      (value) mission, "he wrote." We know this is a small contribution compared      all the resources and talents already working on these issues. But we want to do    we can, working along with many others."
