Remote control no-man submersible "Discovery" number of self-propelled underwater robot "exploration" video screenshot

Xinhua News Agency, "Science" July 26 (Reporter Zhang Xudong) in more than 1000 meters deep dark submarine, according to a pre-programmed self-propelled robot shuttle and over. Is it possible to use another robot to find it and track it at the seabed? Our scientists have done in the South China Sea on the 26th.

On the same day, China's new generation of ocean-going comprehensive scientific research ship "Science" equipped with cable-controlled remote control no-person submersible "Discovery" and autonomous underwater robot "exploration" in the northern South China Sea to achieve deep sea rendezvous shooting, which is the first time in China To achieve the above two types of underwater robot rendezvous shooting.

"Science" is the implementation of the Chinese Academy of Sciences strategic pilot special "tropical Western Pacific marine material energy exchange and its impact" 2017 Nanhai comprehensive inspection voyage, voyage technology chief, Chinese Academy of Sciences Shenyang Institute of Automation deputy director Li Shuo said, It is a simple shot, but it contains a very complex technical system, very exciting.

 "Exploration" and "discovery" to complete the co-operation, was recovered to the mother ship

Li Shuo introduction, "exploration" is the autonomous underwater robot, after the water according to pre-programmed navigation. In this potential, it keeps 5 meters from the sea for optical photography. To achieve these two types of underwater robot rendezvous shooting, "exploration" number of stability and reliability to be very high, navigation position and attitude control to be very accurate, navigation and positioning ability to be very strong, so as to overcome the ocean currents and complex terrain effects, According to the default path and time in the predetermined location.

Voyage chief scientist, Institute of Oceanology, Chinese Academy of Sciences researcher Sun Song said, to achieve the rendezvous shooting, but also the mother ship and remote control no one submerged device "found" the exact match. As the "discovery" and the mother ship has a cable between the connection, so the mother ship to have a very precise power positioning capabilities, and "Discovery" to have accurate navigation and positioning capabilities, accurate and accurate time in the appropriate location, capture and track shooting " Explore "number.

"Two different types of underwater robots and mother ships are controlled by three different teams, and the rendezvous is a reflection of the high level of manipulation of the three teams and the ability to work with each other."

Experts say the cable-controlled and autonomous underwater robot deep-sea rendezvous shoots allows scientists to see the underwater working conditions of autonomous underwater robots. Ship, cable control and autonomous underwater robot co-operation, fully proved China's deep sea technology and equipment system of comprehensive strength, to achieve the deep sea synergy control technology across the future development of deep-sea detection equipment will play a leading role.

"Discovery" and "exploration" to complete the co-operation, was the mother ship hanging out of the water

On the same day, in the "exploration" operation at the same time, "Discovery" also equipped with the Institute of Oceanology, Chinese Academy of Sciences independently developed probe-type Raman spectrometer, the South China Sea a cold spring area of natural gas hydrate composition was detected, For the first time to achieve different types of underwater robots at the same time operations.
