Researchers in Shanghai are developing a six-legged robot that could serve as an assistive device for visually impaired people, similar to a guide dog.
The robot, roughly the size of an English Bulldog, uses cameras, sensors and artificial intelligence to navigate its environment. It can recognize traffic signals and communicate verbally with a human operator.
Its six legs allow it to walk smoothly and remain stable, like the tripod of a camera. This is advantageous over a traditional four-legged guide dog.
The robot is currently undergoing field tests with visually impaired volunteers. One volunteer said it could help her travel independently for tasks like commuting to work or going to the supermarket.
China has a huge shortage of guide dogs, with only around 400 available to support the nearly 20 million visually impaired people. Robot guide dogs could be mass produced to meet demand.
Researchers believe their robot guide dog could significantly improve independence for the visually impaired if commercialized and made more affordable through mass production. This has the potential to help many millions of people worldwide.
