Underwater robot

my country’s research and development of "exploration 4500" independent underwater robots, the first completed the Polarology test underwater robots Polar (science and technology point) exam personnel preparation on deck.

Shenyang Automation Research Institute of Chinese Academy of Sciences is for the picture "Exploration 4500" autonomous underwater robot recycling. The Study of Shenyang Automation Research in the Chinese Academy of Sciences is for the map of the 79-day style test.

A few days ago, with the "Snow Dragon 2" examination boat slowly returned to the Shanghai Domestic Base Terminal, the nerves of the members of the Kodao team were gradually relaxed. In this exam, he and the "exploration 4500" self-underwater robot (hereinafter referred to as "Exploration 4500") was excellent, successfully completed the scientific examination of the Arctic high latitude sea ice coverage area. This is also the first time in my country’s first use of independent underwater robots in the Arctic high latitudes, and the valuable data sheets that have successfully dive will provide important scientific support for Arctic environmental protection. The first north polar is a very poor environment, and the scientific and technological personnel have conducted a series of technical upgrades, and the transformation of Shao Gang is a sub-research staff of the Shenyang Automation Institute of the Chinese Academy of Sciences. This is his first participation in Polar Science. Like him, "exploration 4500" is also the first time. "Exploration 4500" presided over the research institute of Shenyang Automation, appearance like a "big yellow fish". Compared with ordinary uninhabited underwater robots, "Explore 4500" is more independent. Li Yang, deputy researcher in Shenyang Automation, told reporters: "Compared to the remote control underwater robot, ‘Explore 4500’ without cable connection, no artificial intervention can achieve independent navigation and execution detection, life is longer, work The range is also larger.

"Despite the" exploration 4500 "has been strong enough, but it is necessary to go to the extremely harsh environment. The researchers are still not very secure. Before departure, they have a series of technical upgrades, transformation, and improve the system. Reliability. In polar high latitude regions, scientific boats will displace them due to wind, streams, etc., causing the plazing and recycling of underwater robots to be implemented in a relative fixed area, and the ice layer will hinder the mangroves and water. The communication between the robots requires that underwater robots have autonomous guidance capabilities, and can accurately receive the maternal ship instructions, and adjust the operation trajectory according to the status of their own equipment, gradually rejuvenation to the maily during the recycling process, thus achieving automatic, safe recycling .

"Shao Gang introduced.

In response to the characteristics of high-intensity sea ice coverage of the Arctic examination work area, the scientific research team innovatively developed an acoustic remote control and automatic guidance-integrated ice recovery technology, ensuring that "exploration 4500" continued to submit success, and Safe recycling. Shao Gang said: "We also added emergency beacons, and the latter is used to make a relatively accurate direction when the card will not be determined in the ice or the naked eye." In addition, the scientific research team also "explore 4500" The fault handling process is optimized, so that it is independent to determine the state of themselves to make decisions. "After a period of continuous work, you can feel your body as our human beings." Shao Gang said, "If you feel that you’m" is not bad, you will continue to work; if you think it is not good, It will immediately send us a saver, and we will help it.

"Separable to test the polar weather," exploration 4500 "placed and recycling is very safe, but it has been fully prepared, but the polar weather is rapid, the science test team members and" exploration 4500 "have experienced unexpected difficulties in the Arctic Test.

Before an operation, the original dive area is plummeted, and the wind is mixed, and the visibility is very poor.

"At that time, our female ship has a ten seas from this work area. I have been very embarrassed in the navigation process, and I am worried that the equipment is unable to complete the equipment.

"Shao Gang recalls.

When the busil is reaches the underlying area, the weather began to turn off, but the previous cooling and storm snow makes the sea quickly icing, the water range is much lower than before, and it adds great difficulties and risks to the rack of robots.

The robot is nowhere to "foot", and the time of the examination task is urgent and can’t delay. What should I do? Finally, Shao Gang and colleagues decided to use the marshal to break ice, artificially opened a water environment that can be placed underwater robots.

Shao Gang said: "The waters of the ice-break is very small, in fact, it is not conducive to our recycling of underwater robots. Fortunately, we finally completed the cloth and safety recycling, and proved that ‘exploration 4500’ has poor harsh The ability to carry out science test applications in the environment.

"Many regions of the polar ocean are covered by sea ice, and investigating the sea ice characteristics and ice seas are an important part of the polar investigation.

Li Shuo, deputy director of Shenyang Automation Research Institute, said that polar science test has always been the key direction of underwater robot development.

In recent years, the Shenyang Automation Institute has four types of 6 sets of unmanned underwater robots to participate in 8 polar science exams, and made an important contribution to our country. "Self-underwater robots mainly undertake three tasks in polarography.

"Li Yang said," First, the observation and detection of ice floes, understand its thickness, state, and movement conditions; the second is to measure water parameters, including water depth, temperature, salinity, etc., three is to carry out seabed terrain Fine detection, on this basis, some mineral resources in the sea can also be found. "Traditional sea ice test methods are drilled on sea ice, which is relatively low, and the obtained data is limited, and there is a lot of limitations.

Autonomous underwater robots are not affected by sea ice, and can reach the area where someone cannot reach, a larger range, greater depth, and longer scientific investigation. Moreover, the sampling is flexible and accurate, which helps to increase the quality of the collection sample and increase the number of sample collected. "Code staff can visually observe the polarized underwater world through imaging equipment installed by camera, camera and imaging sounds installed on underwater robots." Li Yang said.

Li Shuo said: "This time, it will apply to the Arctic examination task of the North Pole, let us know more about the needs of scientists for intelligent robotics.

The scientific research team will use this as the starting point, closely connect technology innovation and scientific demand, continuously optimize and upgrade, providing more intelligent technical means for the more exploration operations of Arctic examinations in the future, and help scientists get more valuable data And information. "The function of advances can reach millimeters, can be far from thousands of kilometers, the application is more and more widely used in the 1970s, and some countries began to develop uninhabited underwater robots for polar investigating, currently Many types mainly include remote control (cable) and autonomous (cableless).

Li Yang said that my country has been developing underwater robot from the 1980s, and the Shenyang Automation Institute is one of the main R & D units. "But the leaping development of Polar Kicking underwater robots is mainly in more than 10 years. During this period, we have developed a ‘margin Rov’ ‘Northern ARV’ and ‘exploration AUV’ and other underwater robots, and participated in multiple Polar University. Test, all achieved successful applications.

"In recent years, the major needs of the country, Shenyang Automation Institute has been committed to promoting the principical development of underwater robots, and now we have realized all from the water to the water, and it has also achieved a few kilometers. There are thousands of kilometers full coverage.

"Our team is mainly focused on the R & D and application of uninhabited underwater robots. At present, there is currently the main function and performance indicators in my country." Li Yang said.

With the development of underwater machine, its application is also more extensive, and the work environment is increasingly extremely and complex. Li Yang told reporters that in addition to the polar, they currently launched a scientific investigation in the Plateau Lake, the Pacific Plateau, the Pacific Ocean.

"These are very extremely and complex environments, which have highly demanded a high demand for independent control technology of unneaffected robots. We need to carry more sensors in limited space, which is the compatibility of the overall layout and battery. It has been a major challenge.

"In the future, the development of the world’s self-underwater robot will develop toward more intelligent direction, with stronger environmental adaptability and stronger synergy capability." Most of our original autonomous robots are preparatory Before the water, researchers have given it a good program in advance, telling it the goals and paths.

"Li Yang said that with intelligent development, human intervention will be less and less, and the autonomous robot will become more and more smart, and the role is getting bigger and bigger.
