China's key sensors for reconnaissance unmanned vehicles need to be imported and localized in 3-5 years

(Summary description)  On October 17, the finals of the "Over Dangers 2016" Ground Unmanned System Challenge held by the Chinese Army Equipment Department was held in Beijing. Tang Jin, deputy director of the Scientific Research Ordering Bureau of the Army Armament Department, stated at the final press conference that unmanned technology has broad application prospects in the military field and will profoundly change the shape and style of future wars. In layman's terms, people expect that unmanned systems can complete some high-risk tasks or tasks that humans cannot complete in non-war military operations such as war or rescue and disaster relief.     Tang Jin said that this competition represents the highest level of unmanned technology in China in terms of scale and subject difficulty. According to the reporter's understanding, a total of 22 teams stood out from 73 teams from all over the country and advanced to the finals. Their scientific research strength is at the leading level in China. Therefore, industry leaders who come to participate and watch the competition have a considerable say in the development status of unmanned systems and the prospects of their application in future military operations.     Modeling the unknown environment is a worldwide problem   The guest, Deng Zongquan, vice president of Harbin Institute of Technology, was one of the earliest scholars engaged in lunar rover research. In his view, unmanned systems still have a long way to go before they become tools on the battlefield.   Wu Tao, an associate professor at the National University of Defense Technology, interprets the development status of unmanned systems in a popular way as "it can be applied in a known environment, but cannot be modeled in an unknown environment." In this research field, the adaptability of unmanned systems to unstructured environments is a recognized problem, that is, how to improve the adaptability of unmanned systems to unknown environments.   In the competition, Professor Xu Youchun from the Military Transportation Academy led the "Mengshi Intelligent No. 1" team to take the lead in the field battlefield reconnaissance category A and B competitions. In fact, this car not only performed well in this competition, but its previous generations of principle prototypes have already won 3 championships and 3 runner-ups in the "China Smart Car Future Challenge".   Xu Youchun told a reporter from China Youth Daily and China Youth Online that “every cross-country road that can be driven by humans can basically be walked”, and the “Fierce Lion” also has a “walking” function, that is, it can also be used when GPS positioning and navigation are temporarily lost. "Try to find your way" yourself.But in general, the "Fierce Lion" is still in the cub stage, and can only complete the set tasks in the known environment, and does not have the corresponding adaptive ability to the unknown environment.        For example, if the reconnaissance target is set as an oil barrel, Xu Youchun and his teammates can take hundreds of images of oil barrels with different shapes, positions, and lighting conditions, etc., and save them in the system for comparison and recognition by the "Fierce Lion". By designing a fixed route and procedures for how to overcome known obstacles, the "Fierce Lion" can basically complete the task successfully. But the reality is that people cannot predict all the routes and obstacles in the area to be surveyed.   This is not only a problem facing Xu Youchun's team, but the world's unmanned technology research field is facing the dilemma that it cannot model the unknown environment.   Yang Jingyu, a professor at Nanjing University of Science and Technology, has been engaged in unmanned systems research for 25 years. He explained that structured environments can be simulated by non-stop modeling. For example, environmental data on highways can be measured, and machines can be collected and identified. And judgment. "Artificial intelligence has something to do with structured environments. But unstructured environments are difficult to simulate, and the world has not done a good job of modeling in unstructured environments."   For this reason, interviewed professionals such as Wu Tao, Deng Zongquan, and Yang Jingyu all said that from this perspective, China and the United States, the leader in unmanned technology, are not much different. They all need to strengthen theoretical design research on unstructured environments, that is, unknown environments.      My country's R&D strength of basic components needs to be improved   Specific to the current status of domestic unmanned system research and development, the main research and development forces who came to participate and watch the competition clearly saw their own advantages and shortcomings.

  For this reason, interviewed professionals such as Wu Tao, Deng Zongquan, and Yang Jingyu all said that from this perspective, China and the United States, the leader in unmanned technology, are not much different. They all need to strengthen theoretical design research on unstructured environments, that is, unknown environments. 
 
  My country's R&D strength of basic components needs to be improved
  Specific to the current status of domestic unmanned system research and development, the main research and development forces who came to participate and watch the competition clearly saw their own advantages and shortcomings.
  Professionals usually use three dimensions to investigate unmanned systems, including environmental perception, planning and decision-making, and low-level control. The limitations of environmental perception mainly come from two aspects: sensors as hardware systems, and computer algorithms as software systems, whose functions can also be compared to eyes and brains.
       In an interview with a reporter from China Youth Daily and China Youth Online, Wu Tao said that in terms of software algorithms related to unmanned systems, some scientific research institutes, companies and universities in China have already ranked among the world's leading positions. In this regard, China's overall strength cannot be underestimated. 
  However, there is a certain gap between my country and the international leading level in sensor research and development. The reporter learned that in this competition, the Lidar and other key sensors used by the better-performing teams such as the Lions Intelligent No. 1 Team of the Military Transportation Institute, the Shenhu Team of the National University of Defense Technology and the Zebra Leopard Team of the North China Vehicle Research Institute All are imported products. Wu Tao predicts that it will take another three to five years for domestic lidars to be manufactured that are competitive with similar products abroad. However, after three to five years, the price of foreign lidars with the same performance may drop to a few tenths of what it is today. Domestic sensors may further face the suppression of foreign product prices.
  In addition, in terms of underlying control, my country's R&D strength needs to be strengthened.
  The drive-by-wire system is the heart of the unmanned system, and the research and development of related components is best done by the unmanned system research and development organization and the car manufacturer in order to fundamentally solve the matching problem of the drive-by-wire system in the manufacturing process. Otherwise, The modification is difficult and the reliability is poor.
  The unmanned vehicle that Xu Youchun led by the "Mengshi" team used the chassis of a domestic Great Wall Motor model to transform is one of the more successful transformations in this competition, but he still believes that the "reliability is not ideal" and the performance is not stable enough.
  Therefore, when talking about China's shortcomings in the field of unmanned system research and development, Deng Zongquan, vice president of Harbin Institute of Technology, said bluntly: "Basic manufacturing needs to catch up."
 
  Individual technologies such as perception and car body control in a specific environment are becoming mature
  Although on the whole, China and other countries in the world still have a long way to go in the field of unmanned system research and development, it is gratifying that certain individual technologies in unmanned system research and development have matured and are undergoing practical applications. test.
  Xu Youchun introduced that in my country, "unmanned target vehicles" using fixed-line transportation technology have begun to accept practical tests.
       Wu Tao said that Israel Mobileye's ADAS (advanced driver assistance system) products have now occupied 90% of the global market share, and the wide application of this technology will "try to avoid vehicle accidents as much as possible."
  Wu Tao believes that the maturity and perfection of unmanned systems need to withstand the test of sufficiently diverse environments and tasks, including different scenarios, different road conditions, different weather and lighting, etc. Only after enough targeted systematic tests, and constantly revising the system design based on the test results, can the performance of the unmanned system gradually mature.
  And this is exactly the main "challenge" of the "Across the Dangers 2016" Ground Unmanned System Challenge. Professor Yang Jingyu from Nanjing University of Science and Technology told the China Youth Daily and China Youth Daily on randomly distributed rivers, beaches, slopes, gravel roads and muddy roads: "I have not encountered such a complicated environment in 25 years."
       Yang Jingyu believes that, compared with ordinary civilian games, the most prominent feature of the test field prepared by the Army is that the environment is complex and it is unknown before the game. He said: "The simulation is the actual environment, and such an environment is in line with the requirements of the times."
  In fact, being able to compete in a complex environment is also a rare opportunity for participating teams. Talking about the attractiveness of this event, Dr. Chai Hui from Shandong University’s Bison Team sighed: “Where do we usually go to find such test venues!” In this regard, Xu Youchun’s "Mengshi" team and other participating teams also have Feel the same.
  For each team, the ranking of the competition can certainly verify their own level, but exposure to faults such as vehicle trapping, rain causing sensor failure, burning circuit board, etc. is of more important guiding significance for the perfect design of the system.
