72 Robots Join Beijing Parks: Cleaning, Patrolling, Tour Guiding, and Mosquito Control

When visitors enter the Summer Palace, they often are surprised to see a white robot sweeping leaves along the main road. But soon they realize this is not an exception—across 14 municipal parks, including Temple of Heaven, Beihai, Yuyuantan, Zizhuyuan, and Taoranting, 72 robots are now working simultaneously.

These robots cover six major scenarios: cleaning, smart patrol, inquiry and tour guidance, water rescue, green maintenance, and ecological monitoring. They handle the most tedious, dirty, dangerous, and difficult tasks in park management.

At the Summer Palace, during the hottest and most humid days of summer, sanitation workers face significant challenges. Intelligent patrol-sweeping robots equipped with lidar and sensors can start within 30 seconds after workers define the work area and select cleaning mode via a mobile app. They sweep garbage, spray water to reduce dust, clean along edges, and adjust cleaning intensity based on detected litter, while actively avoiding pedestrians and vehicles. The park also deploys intelligent tour-guide robots that follow preset routes, offering navigation, answering questions, and reminding visitors of park rules.
