Hefei Deploys Full-Space Robot Cluster Across Metro Network

During a peak holiday travel period, Hefei rolled out China's first full-space 'robot cluster' across its metro network, deploying humanoid assistants, quadruped robot dogs, drones, and undercarriage inspection units. Officials in Hefei, Anhui province, said the system is designed to support human staff by reducing inspection times and improving operational safety; future plans include integrating large language models as a central control "brain".
