Ningbo-Zhoushan Port has become the first port in China to deploy a quadruped inspection robot for container verification, marking a major milestone in smart port operations.
A four-legged robot developed by Unitree Robotics was put into operation at the Meishan terminal of Ningbo-Zhoushan Port on March 2, autonomously navigating between stacked containers to capture and verify container numbers and seal codes. This is the first time a robot has performed such tasks at a Chinese port, shifting the inspection process from manual, step-by-step verification to an AI-assisted, automated workflow.
The robot is equipped with high-resolution cameras and AI recognition algorithms built on the "Chengfan" model. Customs officers can issue instructions through a dedicated system, allowing the robot to plan its route, avoid obstacles, and collect data in real time. Images are immediately uploaded for verification, forming a traceable and auditable record of each inspection. The technology has proven highly efficient: tasks that previously required four to six personnel over an hour can now be completed in just 20 minutes, with container number recognition accuracy exceeding 99 percent.
The introduction of the robot addresses growing challenges at the port, including a sustained increase in container throughput and limited inspection space, as well as manpower constraints. By integrating robotics and AI into the customs inspection workflow, Ningbo-Zhoushan Port is not only boosting efficiency but also pioneering the application of embodied intelligence in port operations. Authorities plan to further refine AI algorithms, enhance human-robot coordination, and expand the technology to other port scenarios, setting a new benchmark for smart port management in China.
