The first underwater cable-laying robot with an operating speed of kilometers per hour completed the launch test and the laying operation is 1,000 meters per hour.

my country's first underwater cable-laying robot with an operating speed of kilometers per hour, developed by China Southern Power Grid Guangdong Power Grid Company, has completed its launch test, and its laying operation speed can reach 1,000 meters per hour.It is reported that the robot not only achieved a major breakthrough in technology,Its core components have reached 100% independent controllability, marking that the project has successfully crossed over from theoretical research to the physical prototype stage, demonstrating my country's independent innovation capabilities in the field of high-end equipment manufacturing.

In response to the common problems of underwater cable-laying robots such as weak submarine cable sensing capabilities and short continuous operation time, Guangdong Power Grid Company has joined hands with scientific research institutions and enterprises such as the Institute of Automation of the Chinese Academy of Sciences, Harbin Engineering University and Shandong Future Robot Co., Ltd. to form a multi-disciplinary elite research team.

By innovatively integrating "acoustic-optical-magnetic-electrical" multi-modal information, the team developed an efficient submarine cable detection and positioning method, successfully overcoming the anti-interference technical problem in multi-sensor integrated navigation.This innovation not only solves the problem of difficult search and positioning of submarine cables in low-visibility underwater environments, but also effectively avoids the problem of near-bottom underwater navigation failure.

Taking into account the complexity of the seabed environment, the project team carefully designed two travel modes: crawler and sled. Both modes can achieve stable travel on the rare soft soil seabed, thus effectively solving the problem of the robot traveling in such a complex environment.

The robot developed this time will be fully applicable to the rare and soft soil seabed environment offshore my country. Its maximum burial speed can reach 1,000 meters per hour. Compared with traditional operating methods, the operating speed has been nearly doubled.
