China is deploying humanoid robots for street patrols and public interaction, ushering in a new era of automated urban law enforcement that’s already reshaping public safety norms.
At a Glance
- China’s humanoid police robots now patrol cities like Shenzhen and Mianyang
- PM01 units feature voice interaction, facial recognition, and advanced mobility
- Robotic dogs assist human officers with autonomous patrols in key districts
- Multi-modal AI, 5G, and LiDAR enable real-time data collection and enforcement
- Ethical concerns center on surveillance expansion and job automation
Rise of the Robot Patrol
China has transitioned from pilot programs to widespread deployment of AI-powered law enforcement machines. In Mianyang City, humanoid robots and robotic dogs now guide traffic, patrol business districts, and interact with pedestrians. One resident remarked, “It’s my first time to see a robot directing traffic,” reflecting public curiosity and growing comfort with automated policing.
Leading the charge is the PM01 humanoid police robot, developed by EngineAI and launched in December 2024. Deployed in Shenzhen, it features an aluminum exoskeleton, 24 degrees of freedom for lifelike movement, and a rotating torso that allows 320-degree surveillance. Equipped with interactive screens and voice recognition, it facilitates real-time communication between authorities and the public.

Tech Stack Behind the Badge
These mechanical officers are built on multi-modal AI systems, LiDAR mapping, and 5G-enabled data streams that keep robots synced with central command. Facial recognition software links directly to CCTV networks, enabling automated identification of persons of interest during patrols.
China’s robotic dogs, also part of the initiative, are actively deployed in high-footfall zones such as waterfronts and tech parks. As officer Wang Jianhai noted, they “perform autonomous patrol” and assist human counterparts in carrying out routine tasks. These dog-shaped robots complement humanoid patrols, extending operational range and terrain coverage.
Ethics and Oversight
Although China leads the global rollout of robot policing, the initiative has raised ethical concerns over privacy and surveillance. Integrated biometric scanning and behavior tracking have sparked debate over civil liberties and data protection.
Automation’s potential impact on employment is also under scrutiny, as robotic systems increasingly assume responsibilities once handled by humans. Still, some residents view the shift favorably. One international visitor described the change as part of “a great consumption experience in China,” reflecting public adaptation to high-tech governance.
China’s rapid implementation across cities like Shenzhen and Lianyungang signals a global inflection point. Whether these robotic officers become the gold standard or a cautionary tale will depend on how governments manage transparency, accountability, and public trust in the age of machine-led policing.
