Researchers in Shanghai are developing a robot “guide dog” that could help blind people. The robot is currently being tested in Shanghai. The machine uses cameras and sensors to navigate its environment. It is able to recognize traffic light signals which traditional guide dogs are unable to recognize. The robot can communicate. It is able to listen and speak with a blind operator. The robot also uses artificial intelligence (AI) to recognize voices, plan ways to go from place to place and identify traffic lights. The robot dog is described as being about the size of an English bulldog but a little wider than a real dog. It has six legs instead of four because the researchers say the extra legs make it more stable, making its movements smoother.
