Recently, in the underground cable tunnel of Yuquanying, Fengtai District, Beijing, the Unitree B2 quadruped robot from Yushu Technology is conducting a careful and meticulous inspection task in the power pipe gallery. It is equipped with intelligent sensors such as visible light video, high-precision infrared imaging, partial discharge detection, gas detection, etc., which can automatically collect data and transmit it back to the operation and maintenance control center. This robot is equipped with a load of 40 kilograms. Capable of climbing slopes, stairs, forward and reverse movement, and turning around. And the accuracy of the fully autonomous motion trajectory is very high, even in narrow areas, it can operate fully autonomously.
Unlike traditional manual inspection operations, this quadruped robot can complete autonomous inspection tasks through remote scheduling, and can detect risk warnings in the first time, cooperate with operation and maintenance personnel for rapid intervention, minimize operational risks, and improve personnel safety.
The Yuquanying Cable Digital Tunnel is the first power tunnel to apply digital unmanned inspection technology
It is reported that the total length of Yuquanying Cable Digital Tunnel is 1.2 kilometers, which is a demonstration section built by State Grid Beijing Cable Company and the first power tunnel in China to apply digital unmanned inspection technology. The tunnel is equipped with complete sensing equipment, including quadruped unmanned inspection robots (i.e. robotic dogs) specifically designed for power tunnels, as well as 5 other categories and 11 types of on-site monitoring devices. These devices together form a digital unmanned inspection system, which enables comprehensive and seamless monitoring of power tunnels.

In the video, the Unitree B2 quadruped robot is over 1 meter tall and is equipped with a flexible mechanical arm about 1.2 meters long on the back of the robot. Together with a detection module, it completes partial discharge detection tasks in the power pipe gallery. In addition, the Unitree B2 quadruped robot is equipped with infrared temperature measurement devices and visible light cameras, which can record and analyze the temperature and status of cables in real time.
As a core member of the digital unmanned inspection system, the Unitree B2 quadruped robot has powerful autonomous navigation capabilities and can move autonomously in complex tunnel environments, effectively replacing accidental electric shock, false positives, and missed detections caused by limited space in manual inspection operations. Secondly, the multifunctional detection module equipped on the Unitree B2 quadruped robot, combined with the robotic arm, can monitor the real-time operation status of the equipment, detect potential problems in a timely manner, and provide strong support for operation and maintenance personnel. In addition, the Unitree B2 quadruped robot has a single endurance of over 4 hours, and with the fast charging module, it can achieve high-frequency, precise, and unmanned autonomous inspection tasks.

It is worth mentioning that this is not the first time the Unitree B2 quadruped robot has appeared in public view. In previous industry inspection tracks, the robot has completed tasks including power inspection, fire rescue, earthquake relief, and survey exploration。
I hope the emergence of robots will be used to replace humans in existing dangerous positions, rather than competing with ordinary people for jobs
Yes, the original intention of robots is to serve humans, not to exploit their living space
