Scientists in Shanghai are developing a robot “guide dog” that could help blind people. The robot is able to tell the environment. It can also read traffic lights which traditional guide dogs cannot. The robot uses AI to hear voices. It is able to listen to and speak with a blind owner.
The robot dog is described as about the size of an English bulldog but a little wider than a real dog. It has six legs instead of four because the other two legs make it less likely to fall down and its movements smoother. Professor (教授) Gao Feng, head of the research team, said, “When three legs are lifted, there are still three legs. It is the strongest shape.”
It is said that there are just over 400 traditional guide dogs in China for nearly 20 million blind people. So robot guide dogs are badly needed. However, they cost a lot. “It's a bit like cars. I can make a large number of robot dogs in the same way as cars, so they will become more affordable,” Gao said. He thinks there could be a large market for his robot dogs. “There might be tens of millions of people in the world who need guide dogs,” he added.

上海的科学家们正在研发一种能帮助盲人的机器人“导盲犬”。这种机器人能够感知环境。它还能识别交通信号灯，而传统的导盲犬却做不到这一点。该机器人运用人工智能来识别声音。它能够与盲人主人进行倾听和交流。
这种机器狗的体型大约和英国斗牛犬相当，但比真正的狗略宽。它有六条腿而不是四条，因为另外两条腿能使它更不容易摔倒，且行动更平稳。研究团队负责人高峰教授说：“当抬起三条腿时，仍然还有三条腿支撑。这是最稳固的形态。”
据说，在中国，针对近2000万的盲人，仅有400多只传统导盲犬。因此，机器人导盲犬的需求十分迫切。然而，它们的成本很高。“这有点像汽车。我可以用生产汽车的方式来大量制造机器狗，这样它们就会变得更实惠。”高峰说道。他认为他的机器狗会有很大的市场。“世界上可能有数千万人需要导盲犬。”他补充道。
