  • Researchers in Shanghai are developing a robot "guide dog" that could help blind people.
  • 2
  • The robot is currently being tested in Shanghai.
  • 3
  • The machine uses cameras and sensors to navigate its environment.
  • 4
  • It is able to recognize traffic light signals which traditional guide dogs are unable to recognize.
  • 5
  • The robot can communicate.
  • 6
  • It is able to listen and speak with a blind operator.
  • 7
  • The robot also uses artificial intelligence (AI) to recognize voices, plan ways to go from place to place and identify traffic lights.
  • 8
  • The robot dog is described as being about the size of an English bulldog but a little wider than a real dog.
  • 9
  • It has six legs instead of four because the researchers say the extra legs make it more stable, making its movements smoother.
  • 10
  • Professor Gao Feng is the head of the research team that is developing the dog at Jiao Tong University's School of Mechanical Engineering.
  • 11
  • "When three legs are lifted, there are still three legs...It is the most stable shape," he said.
  • 12
  • Forty-one-year-old Li Fei and 42-year-old Zhu Sibin are among the people with vision problems who are helping the Jiao Tong University team.
  • 13
  • They are testing the dog using Chinese-language commands.
  • 14
  • Li is completely blind while Zhu has limited eyesight.
  • 15
  • He normally uses a cane to walk.
  • 16
  • Li said, "If this robot guide dog comes onto the market and I could use it, at least it could solve some of my problems in travelling alone."
  • 17
  • Robot guide dogs are also under development in Australia and Britain.
  • 18
  • But China has a big shortage of traditional guide dogs. Gao said there are just over 400 guide dogs in China for nearly 20 million blind people.
  • 19
  • Pet ownership and service animals are a fairly new idea in the country.
  • 20
  • Many workplaces, restaurants and public areas do not welcome a usual service dog like a Labrador.
  • 21
  • The supply of real dogs is limited by breeding and training needs.
  • 22
  • Gao said the production of robot guide dogs could be increased to an industrial level, especially in a manufacturing center like China.
  • 23
  • "It's a bit like cars. I can mass-produce them in the same way as cars, so [they] will become more affordable," Gao said.
  • 24
  • The researcher thinks there could be a large market for his robot dogs.
  • 25
  • "...There might be tens of millions of people in the world who need guide dogs," he added.
