　　A total of 72 robot "employees" have been deployed across14 municipal parks in Beijing this summer, taking on tasks ranging from cleaning and patrols to providing guided tours, detecting pests and discouraging inappropriate behaviors, Beijing Daily reported on Wednesday.

　　At the Summer Palace, cleaning robots can begin operating within 30 seconds after sanitation workers define their operating areas and select cleaning modes through a mobile app. Equipped with lidar systems and sensors, the robots can perceive their surroundings in real time, with side brushes continuously sweeping inward to collect litter along their routes.

　　The robots are capable of edge cleaning and automatic water spraying, and can adjust cleaning intensity based on the amount of waste detected. They can also actively avoid pedestrians and vehicles.

　　The park has also integrated intelligent tour guide robots that can provide explanations along preset routes while also answering visitors" questions and reminding them to maintain order.

　　At Yuyuantan Park, 11 robots have taken up duties. A 1.5-meter-tall white patrol robot can smoothly navigate among visitors. Equipped with more than 10 high-precision AI models, external sensing radar and recognition cameras, the robot can identify behaviors such as smoking and issue voice reminders to visitors through preset audio messages.

　　Meanwhile, Zizhuyuan Park has introduced four types of "smart breathing" robots that simulate human exhaled carbon dioxide to attract and capture mosquitoes, helping reduce mosquito density in specific areas.
