3500 meter undersea easy sampling underwater robot

  • Detail

Yesterday afternoon, in order to avoid the typhoon landing in Guangdong early this morning, China's most advanced 5600 ton civil ocean scientific expedition ship, "Dayang 1", set sail from Guangzhou one day in advance to start China's 21st ocean scientific expedition. Yangcheng Evening News was invited to board the ship to observe the "underwater robot" that appeared for the first time on the Chinese scientific research ship. It is understood that this robot can take photos, videos and samples at a depth of 3500 meters

According to Tao Chunhui, the chief scientist of

the scientific research area will involve three oceans. The ocean scientific research operation will last 318 days, with a voyage of about 35000 nautical miles, divided into eight segments. It is expected to return to Qingdao on May 31, 2010. It is the largest ocean scientific research operation with the longest duration and the highest scientific and technological content in China. 308 scientific researchers from 33 scientific research institutes at home and abroad will participate in the operation if they feel they can commit crimes. Tao Chunhui said that this voyage will face three major challenges: the longest ocean survey, the heaviest task and the latest technology. For the first time, high-tech means such as deep-sea seismograph and underwater robot will be adopted, which is a new test for ship support, personnel organization and technical equipment. The survey area of this scientific research involves three oceans. On the other hand, it will dock in Micronesia, Ecuador, South Africa and Mauritius. The detection speed is fast. When measuring, put the test piece vertically on the torque disc and cross the pirate area

"the main objective of this voyage is to comprehensively investigate seabed mineral resources such as polymetallic sulphides, cobalt rich crusts and polymetallic nodules, taking into account the investigation of marine environment and biodiversity." Tao Chunhui said that China first carried out the investigation of submarine sulfide in 2005. At present, 13 submarine hydrothermal areas (formed after submarine volcanic eruption) have been found, and the number is in the leading position in the world

the value of underwater robots is tens of millions

it is learned that metal sulfides only exist near submarine active volcanoes, and cobalt rich crusts are the components in the sediments after volcanic eruption. These minerals are rich in rare metals and anticancer substances, which have important research value. At a depth of 4000 meters, a large number of known rich mineral and biological resources are waiting for scientific researchers to discover

Cui Yunlu from the North Sea Branch of the State Oceanic Administration is responsible for the technical management of ocean survey equipment. He showed the Yangcheng Evening News the most advanced "underwater robot" in China. The robot is the size of a medium-sized van, and the front square is equipped with a digital camera, digital video recorder and flash lamp. On the left in front, there is a "five function manipulator", which is used for fine seabed operation. It can catch rocks only 10 cm in size and sample the gas. The "seven function manipulator" equipped on the left side of the front can grasp the seabed rock weighing 250 kg. The manipulator can simulate the coarse and fine functions of human shoulder joint, big arm, elbow joint, forearm, wrist joint and palm. It is jointly developed by China and the UK. This "underwater robot" is worth tens of millions of yuan and can move freely on the 3500 meter deep seabed
