This picture shows the Blind Driver Challenge vehicle, which was designed to help people with sight disabilities drive safely. A laser sensor works by sending out a beam that bounces back to the device when it hits an obstacle to measure the distance between the buggy and the item. [Photo/icpress.cn] |
