China’s First Traffic Robot Squad Debuts in Hangzhou
China has deployed its first-ever formal traffic management robot squad in the eastern city of Hangzhou, marking a significant milestone in the application of artificial intelligence and robotics to urban governance. The 15-robot unit, named “Hangzhou Police Smart Mobility” (杭警智行), officially began duty on May 1, 2026, across key areas of the city including the West Lake scenic district, Hubin commercial area, and major thoroughfares, according to People’s Daily.
A New Kind of Traffic Officer
Standing 1.88 meters tall and designed to resemble Hangzhou’s traffic police mobile unit officers, each robot is equipped with a four-wheel mobile chassis, a standard black police cap, and fluorescent yellow-green reflective armor. But their appearance is only the beginning — beneath the surface lies a sophisticated integration of artificial intelligence, the Internet of Things, and big data technology.
As an official from the Hangzhou Public Security Bureau Traffic Management Bureau told Xinhua News Agency, “The ‘Hangzhou Police Smart Mobility’ robot is by no means a simple gesture imitator, but integrates artificial intelligence, the Internet of Things, and big data technology, possessing multi-dimensional, intelligent traffic management capabilities and ultra-long endurance characteristics.”
The robots boast three core capabilities. First, they can direct traffic with millisecond-level synchronization to traffic signal control systems, executing eight types of command gestures — including stop, straight, and left turn — that are fully aligned with signal light phases. Second, they use high-performance visual recognition algorithms for 24/7 multi-target monitoring, capable of detecting violations such as non-motor vehicles crossing stop lines, riders not wearing helmets, and pedestrians lingering in vehicle lanes. After three warnings without correction, violation evidence is recorded and sent to the bureau’s early warning center. Third, they serve as public inquiry terminals, allowing pedestrians to ask for directions through a touchscreen interface powered by a voice large model that provides optimal walking or public transit routes without requiring any app download.
Impressive Early Results
During the Labor Day holiday period from May 1 to 5, the squad accumulated 647.7 hours of operation, issued over 25,000 traffic violation warnings, and provided more than 2,000 consultation services. On average, the robots issued a reminder every 1 minute and 43 seconds while on duty.
Chen Sanchuan, Deputy Squadron Leader of the Wulin Squadron, Gongshu Brigade, Hangzhou Traffic Management Bureau, praised the new technology. “With the ‘new colleague’ assisting, daily duty is indeed much easier and calmer,” he told People’s Daily. “The new partner can stay stably on duty for long periods, helping everyone share a large amount of basic work, allowing our officers more energy to handle accidents and emergency situations.”
The development of the robots began in June 2025 by the Hangzhou Traffic Management Bureau’s Science and Technology Department. According to Chen Qihang, a police officer involved in the research and development, the team surveyed 28 typical intersections, collected over 1,200 hours of road test data, and underwent four rounds of core technology iteration before finalizing the design. The robots first appeared publicly during the March 2026 West Lake Half Marathon, where they assisted with traffic security alongside drones.
Broader Context: Hangzhou’s Robotics Revolution
The deployment of the traffic robot squad is not an isolated event but part of a much larger story. Hangzhou has positioned itself as a national leader in artificial intelligence and robotics, aiming to become “China’s first city for AI innovation.” The city has gathered over 700 robotics-related enterprises, including well-known companies like Unitree and Deep Robotics. In 2025, the embodied intelligence robotics cluster output value reached 106.8 billion yuan (approximately $14.7 billion). Notably, four-legged robots and humanoid robots from Hangzhou account for over 80% and 50% of the national market share respectively, as The Paper reported.
Landmark Legislation
On the same day the robot squad began duty — May 1, 2026 — China’s first local regulation focused on embodied intelligence robots officially took effect in Hangzhou. The “Hangzhou Regulations on Promoting the Development of the Embodied Intelligence Robot Industry” comprises seven chapters and 50 articles covering technological innovation, infrastructure, industrial development, application empowerment, and safety management, according to Hangzhou News.
The legislation explicitly supports the application of innovative products in the embodied intelligence robot field, encourages administrative organs and public institutions to open application scenarios, and promotes government procurement of independent innovation products. It also supports first trials and large-scale application of embodied intelligence robots in public scenarios.
Implications and Outlook
The Hangzhou traffic robot squad represents a shift from human-only traffic management to a “human-machine collaboration, complementary advantages” model. By handling repetitive tasks such as issuing warnings and providing directions, the robots free police officers to focus on higher-value activities like accident response and emergency management.
If successful, this model could be replicated in other Chinese cities, potentially creating a new market for traffic management robots. The technology partner behind the robots, Zhongkong Information, has already deployed similar systems in cities including Hainan’s Chengmai, Jiangsu’s Suzhou and Suqian, and Zhejiang’s Jiaxing, Lishui, Tongxiang, and Haining.
However, the deployment also raises questions about privacy, given the robots’ visual recognition capabilities for detecting violations in public spaces. The long-term maintenance costs, public acceptance, and plans for expanding the squad beyond 15 robots remain open questions as Hangzhou continues to pioneer the integration of embodied intelligence into everyday urban life.
