Recently, an unmanned sweeping vehicle appeared in the square of Cangzhou High-speed Railway West Station. Although it is small, its cleaning ability is not bad, and it can clean an area of 3000 square meters per hour. It is understood that this unmanned sweeper is called "Xiaobai", which integrates sensors such as lidar, camera, and ultrasonic radar. Through the sensors around the body, it can quickly identify obstacles and pedestrians and locate them. It is completely separated from manual operation, and can autonomously complete cleaning, sprinkling, garbage collection and other tasks on the road. In addition to the automatic obstacle avoidance function, "Woxiaobai" also has functions such as autonomous tracking and fixed-point start and stop, which can clean the edges and dead corners of the road. According to the staff of Zhonghuanjie (Cangzhou) Environmental Service Co., Ltd., a "Snail White" can work for 6 people.
