At the Summer Palace Museum, an intelligent guide robot gives scheduled free tours and answers visitor questions. Elsewhere in the park, cleaning robots work through the night, while patrol robots on the Longevity Hill Road of the park scan trees for pests and can identify more than 500 bird species and nearly 100 other wildlife species. At Yuyuantan Park, inspection vehicles equipped with cameras and sensors can detect litter, standing water and problems with manhole covers. Robots operating on the water can also cut and collect aquatic vegetation. At Temple of Heaven Park, patrol robots can identify more than 10 types of inappropriate visitor behavior, including smoking and bringing pets into the park, helping staff maintain order.
