Since the beginning of this year, the deep-sea autonomous underwater robot “Qianlong No.2†independently developed by the Shenyang Institute of Automation of the Chinese Academy of Sciences and the self-controlled remote-controlled hybrid underwater vehicle “Haidou†have successfully completed experimental applications. The former has obtained the hydrothermal detection of the ocean in China. A major breakthrough, the latter was successfully applied in China's first 10,000-meter abyss voyage, with a maximum dive depth of 10,767 meters. It is understood that China's underwater robot technology has reached the international advanced technology level, but compared with developed countries, there are still problems such as slow application of results and large gaps in the construction of ecological systems. It is advisable to take advantage of the situation and accelerate the development of a new generation of underwater from a strategic height. robot. Underwater robots help marine science Feng Xisheng, an academician of the Chinese Academy of Engineering and a researcher at the Institute of Automation, said that over the past 30 years, the automation institute has successively researched the first underwater robot in China, the first 6,000-meter cableless autonomous underwater robot in China, and the first polar underwater test robot in China. Such products are widely used in marine science, deep sea resource exploration, and submarine rescue and other fields. In 2012, China's first “Zhenlong†manned submersible broke the world's largest submarine depth of the same type of manned submersible in the 7000-meter sea trial, meaning that the submersible can occupy the world's ocean area. 99.8% of the vast sea area works. Its 6,000-meter autonomous underwater robots “CR-01â€, “Qianlong No.1†and “Qianlong No.2†have played an important role in determining the China Ocean Association’s submarine exploration area and formulating mining plans. “Qianlong No.2†uses a number of innovative technologies: the first use of forward-looking sonar-based collision avoidance control method has greatly improved the ability to avoid obstacles. For the first time, a magnetic detection sensor was installed on the AUV to achieve high precision near the sea. Magnetic detection; using the sounding side sweeping sound å‘ underwater real-time signal processing technology to achieve rapid mapping of high-precision topography in the deep sea. Compared with the "Jianlong", the "Qianlong" series has no cable traction and no passengers. It can realize autonomous navigation, self-operation and self-protection, with a wider range of activities and lower costs. Liu Jian, chief designer of "Qianlong No. 2", said that the successful development of two application-type underwater robots, "Qianlong No.1" and "Qianlong No.2", has marked that China's autonomous underwater robot technology has reached the international advanced level. It is of practical significance to improve the scale and level of development and utilization of deep-sea resources in China. China’s first 10,000-meter underwater robot “Haidou†successfully obtained two 9000-meter and two 10,000-meter grades in the first comprehensive 10,000-meter abyss in China’s “Exploration No.1†voyage. The temperature and salt depth data of the vertical section of the abyss provide valuable basic data for studying the spatial variation of the characteristics of the abyss water mass and the oceanic structure of the abyss and the design of the 10,000-meter unmanned/manned submersible. Technology to application faces "a few hurdles" It is understood that China's underwater robot technology is advanced, but there are still few applicable products. The transformation of advanced technology into practical applications is relatively slow, and it has an impact on marine development. Experts said that the current development of underwater robots is not the same, lacking top-level planning. At present, many departments and units in China have successively proposed and developed prototypes of multi-type underwater robots from their respective perspectives, presenting the trend of the development of Wanma Pentium. However, due to the lack of communication between the various units, many of the key technologies solved by the prototypes are low-level repetitions, wasting research funding. Second, the R&D to industrialization and application are facing faults. "What has been done abroad can be used immediately. After using it to test which place is not suitable, it will be changed immediately. A benign iterative relationship has been formed. We have fewer products now, less application opportunities, and the annual number of autonomous underwater robots in the United States. Up to several hundred times, 'Qianlong No. 1' is only a few dozen times. In the long run, the gap between technology and foreign technology may gradually widen." Liu Jian said. Academician Feng Xisheng pointed out that the performance of some of the underwater machines in China is similar to that of foreign countries, but the ecological system construction is far from the same. In the field of underwater robots, foreign countries have formed a system of research, design, manufacturing, application, service, science, competition, education and personnel training. An independent industrial department has been established, forming materials, parts, complete machines and supporting systems. Industrial chain such as special ships. "And most of China's research institutions are leading research and development, and there is very little participation in enterprises." Third, there are problems in the development of key components and talent reserves. "The 'Qianlong No. 2' is built by our own body, controller and carrier structure, but the high-precision sensor and core navigation positioning mainly rely on imports, which is a big gap between us and foreign countries." Liu Jian said . Li Shuo, director of the Marine Technology and Equipment Research Office, said that the development of underwater robots is closely related to energy, sensors, control, communication, and artificial intelligence. In addition, due to contact with seawater medium, low-density, high-strength materials, as well as sealing and anti-corrosion, are also unique technologies for underwater robots. To realize the development of underwater robots to deeper, farther, and more powerful goals, research on key technologies must be carried out first. It is also difficult for current technicians to meet application security needs. "A sea trial to ensure that the machine runs at least a dozen people, one is more than 100 days, the main responsible person asked to go, sometimes not sent out." Seize the opportunity to attack the new generation Experts say that underwater robots are a necessary tool for building a maritime power, defending national security and achieving sustainable development. After years of catching up with the development of underwater robots in China, some technologies have been aligned with foreign countries. It is urgent to further integrate the industrial chain resources, actively promote the transformation of underwater robots, and cope with the development of a new generation of deep sea, sea and combined underwater robots. The first is to integrate resources and promote multi-disciplinary joint research. Underwater robots involve more than ten disciplines such as intelligent control, mechanics and structure, communication and network, pattern recognition, and sonar technology. It is recommended to plan the development of underwater robots from the top level to form a systematic and serialized development trend. The second is to strengthen transformation and further transform underwater robot technology into productivity. Experts such as Feng Xisheng and Liu Jian suggested that the research institutes should develop engineering practical prototypes, which are still far away from mature market-oriented products. Moreover, underwater robot products have high technical content, large investment and high risk. Therefore, it is necessary to establish an industrialization system that is application-oriented, enterprise-led, and supported by institutions, so that new technologies and new equipment can quickly form products into application. The third is accurate positioning, focusing on the development of underwater robots such as unmanned, intelligent and informationized, and planning to form the underwater robot industry. Academician Feng Xisheng said that the current prediction of the underwater robot revolution is: the mixing of water surface and underwater robots is called hybrid robot. "It can be integrated, modular, or multiple robots. You can also connect with surface robots and work with airborne and ground robots." Experts suggest that it is advisable to encourage and guide the use of advanced information, electronics, sensors, materials and intelligent control technologies to significantly enhance the environmental awareness, self-determination and operational capabilities of individual underwater robots. On the basis of major breakthroughs, the rapid development of robot cluster technology will form the underwater robot industry.
