The 27th China International High tech Fair (CHTF) kicked off grandly at the Bao'an International Convention and Exhibition Center in Shenzhen. At this year's High Tech Fair, the Yuejia Lingdong Robot Dog made its debut as a cutting-edge force in the field of embodied intelligent robots, and jointly completed a functional demonstration in a real operating environment with Shenzhen Metro. The "embodied intelligent inspection solution" jointly released with Shenzhen Metro is not a conceptual demonstration, but a mature achievement that has been put into practical application on some lines of Shenzhen Metro. This marks the successful integration of embodied intelligent robots into the daily operation and maintenance system of urban rail transit, opening a pragmatic new chapter in the construction of smart urban rail transit. From concept verification to value implementation, embodied intelligence opens a new chapter in urban rail transit reform. As a national level technology benchmark, the High Tech Fair is always committed to showcasing cutting-edge technologies that can be implemented and promoted. The appearance of the Vietnamese agile robot dog this time is a perfect embodiment of this concept. It is not just for the grand event, but with the practical achievements accumulated on the front line of Shenzhen Metro. Under the spotlight of Bao'an International Convention and Exhibition Center, Yuejia Lingdong showcases its proven abilities in real and complex environments such as subway tunnels, station halls, escalators, etc., achieving a value leap from "exhibits" to "industrial grade tools" and laying a solid and reliable first public impression for the brand. The value of Yuejia Lingdong in Shenzhen Metro lies in its targeted solutions to a series of specific and challenging operational problems by delving into practical scenarios to solve the core pain points of subway operation and maintenance. All terrain inspection has no blind spots: it can autonomously pass through straight stairs, escalators, and staircases, replacing manual entry into high-risk areas such as pipe galleries for daily and nighttime inspections, fundamentally ensuring personnel safety. Accurate warning of safety hazards: The system has multi-dimensional hazard identification capabilities, which can accurately detect open flames, low-temperature flames, electric sparks, and smoke, achieve early fire warning, and push alarm information to the command center in real time. Long term management of facility health: Through AI real-time temperature measurement and trend analysis, the system can warn of equipment failure precursors. Based on continuously collected data, automatically construct a realistic 3D model to provide scientific basis for predictive maintenance of facility assets. The successful application of the reusable "Shenzhen Railway Solution" Yuejia Smart Robot Dog, which sets a benchmark for smart rail transit, in Shenzhen Metro is not only a technical validation, but also a successful model innovation. As a reliable 'intelligent inspector', it is able to perform tasks such as equipment status recognition, environmental anomaly alarm, and specific facility inspection on a regular basis, effectively improving operation and maintenance efficiency and safety. This cooperation model provides a highly feasible "deep rail solution" and "Vietnamese agile model" for the operation and management of rail transit nationwide and even globally, proving the enormous practical value of embodied intelligent robots as a new quality productivity in promoting the intelligent upgrading of urban key infrastructure. Looking ahead to the value verification and promotion path from Shenzhen Railway to future embodied intelligence, the Yuejia agile robot will continue to deepen technology research and application expansion based on its successful practice in Shenzhen Metro. It will play a key role in many fields such as power inspection, hazardous chemical supervision, logistics warehousing, emergency rescue, etc. They are not only tools, but also a new type of productivity that reconstructs production processes, improves operational efficiency, and ensures job safety. With technological iteration and deep cultivation of scenarios, embodied intelligence will inevitably become an important engine for promoting the intelligent upgrading of thousands of industries, injecting strong momentum into the development of new quality productivity and the construction of a digital China.
