Thank you for your cooperation,” said Huang Tiantian, a robot working at an expressway exit station in Bao’an district of Shenzhen. As the first robot with actual combat ( 战斗 ) capability applied at a police station, Huang is good at accurate facial recognition, AI voice interaction and intelligent learning. In the fight against COVID-19, Huang acts as a traffic guide on the front line. “Huang’s post, the traffic guidance area, requires four police officers on duty around the clock. Now it can tirelessly handle the post with high efficiency,” said Xie Xueliang, a public security bureau officer in Bao’an. While Huang is working, its robot colleague, a patrol ( 巡逻 ) robot, is dedicatedly making its rounds. In addition to remote communication and code scanning registration, the patrol robot has six cameras that can automatically monitor people’s temperatures as long as they are within the monitoring scope. Therefore, drivers don’t have to stop a car or wait in line to get their temperatures checked. In addition, the Bao’an police put drones ( 无人机 ) on duty, as well. If people gather or do not wear masks, the drones can record it immediately. Then, the police on duty can directly issue a warning through the drone. “Robots on duty reduce the risk of cross infection caused by close contact between people, which is a good thing for the police and citizens,” said a local resident.
