Robotic dog to guide the blind and visually impaired

BERKELEY — American researchers have developed an entirely autonomous robot capable of guiding partially and non-sighted humans around obstacles and in confined spaces.

Drawing on innovative technologies, researchers at the University of California, Berkeley, in the United States have built a robot that is fully autonomous in an urban environment. To perceive its surroundings, the robot is equipped with a system of range-finding lasers. It also has a rotating camera that follows its visually impaired master or mistress to determine their position.

As Li Zhongyu explains, “With the help of a robot guide dog, we can transfer our code directly from one robot to another”. In contrast to training for traditional guide dogs, which is costly and time consuming, the behaviour of robot dogs canbe instantly improved by updating their programming.
