Deep sea multi-point landing vehicle and rover submersible system

The "Luling" deep-sea multi-point lander and rover submersible system is a new concept unmanned submersible designed specifically for extreme environments such as cold springs and hydrothermal fluids. It innovatively draws on deep space detector technology, integrating the long-term fixed-point stationing of the Multi Point Lander (M-Lander) with the maneuvering detection of the Roaming Submersible (R-ROV). Through the mode of "mobile base station guiding sub machine operations", it achieves efficient and low-cost exploration of multiple underwater points in a single dive. The entire system relies on multiple communication technologies such as acoustics, radio, and fiber optics to ensure reliable operation and real-time data transmission in complex deep-sea environments, providing new equipment and technical support for precise deep-sea bottom exploration operations in extreme environments.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

(1) The "Deep Sea Multi Point Lander and Rover Submarine System" is a new concept submersible consisting of two equipment: the Multi Point Lander (M-Lander) and the Rover Submarine (R-ROV). R-ROV has two modes: floating in water and crawling on the seabed. The crawling mode R-ROV consists of a floating mode R-ROV equipped with a crawling chassis, and the two modes need to be switched on the mother ship before launching for operation. With the support of the national key research and development program "Deep Sea Key Technologies and Equipment" and the key special project "Research on Deep Sea Multi Point Lander and Roamer Submersible System", the new concept submersible "Luling" developed by the Institute of Deep Sea of the Chinese Academy of Sciences has successfully completed sea trial acceptance. During the experiment, the maximum diving depth of the "Luling" was 3252 meters, and a single dive completed a cumulative total of 11 locations.
