The Rover submersible, a new deep-sea base station ROV system developed by the Shenyang Institute of Automation, Chinese Academy of Sciences, was mounted on the multi-point lander Luling Hao and successfully completed the 3000-meter-class sea acceptance trial.
In the acceptance trial, the Rover submersible successfully verified its functional and technical indicators at a 3000-meter seabed, including maximum operating depth, movement radius, and dual modes of free swimming and crawling. It achieved autonomous docking guided by a miniature sonar, deployed and recovered markers with a self-developed 5-function modular manipulator, and completed deep-sea biological sampling.
The development of the Rover submersible has broken through key technologies such as modular docking with dual motion modes, hybrid power supply of cable and battery pack, and adaptive walking on complex seabed sediments based on swing-arm tracks. It is capable of long-term fine detection and operation near the seabed.
The successful development of the Rover submersible has laid a technical foundation for the research and development of large-scale base station ROV equipment, and has broad application prospects in future marine engineering and scientific exploration operations.
