The maximum size is less than 0.4 meters, the weight is less than 40 kilograms, and the operating radius can reach 100 meters. The small mini unmanned special submersible (hereinafter referred to as the mini ROV) is installed on the "Jiaolong", although it is very small, but it is right. In the field of deep sea exploration in China, however, it has a great effect. Recently, the "Eleventh Five-Year Plan" and "863" project undertaken by Shenyang Automation-mini unmanned special submersible vehicles passed the national technical acceptance. "The miniature ROV can be combined with the 'Jiaolong' manned submersible to form a sub-submersible submersible, which can complete the detection of the complex environment around the manned submersible's operating area under 7000 meters of water and improve the operation of manned submersibles in large depth Safety. After completing the pool test, next year, the micro ROV will be installed on the "Jiaolong" for 7000 meters deep sea operations. "Wang Xiaohui, director of the underwater robot technology laboratory of the Shenyang Institute of Automation, Chinese Academy of Sciences, told reporters. Wang Xiaohui said that this subject is at the forefront of domestic research in areas such as pressure-bearing electronic technology, micro-optical cable management system, manned submersible carrying technology, and cooperative operation with manned submersibles. New technologies with independent intellectual property rights In order to expand the field and scope of marine development operations and meet the task requirements of marine development operations, Shenyang Institute of Automation began research on micro ROVs in 2008. The miniature ROV research involves a number of key technologies such as the overall design technology of the large-depth miniature remote control submersible, the deployment technology on the manned submersible, and so on. From the beginning of the research, Wang Xiaohui and the members of the research team aimed the research goal at the forefront of the world's deep-sea high-tech development. After more than 4 years of hard work, the research team finally solved the technical difficulties related to micro ROV, developed an independent intellectual property right, suitable for 7000 meters manned submersibles, can observe in the complex and dangerous deep sea environment of 7000 meters, And a prototype of a micro ROV system with simple operation capabilities. At the same time, they also carried out research on the test technology of pressure-bearing electronic equipment and batteries, designed a test system, and developed a micro-optical cable retracting system, which laid the foundation for the design of the piezoelectric sub-system in the future, and realized underwater retracting and control. It is understood that the micro ROV body has its own energy source, flexible movement, and has the characteristics of large depth, small size, optical cable retractable control, and can be carried by manned submersibles. Its equipped camera is a major highlight. The camera expands the observation range of the manned submersible and can replace the manned submersible for observation in inaccessible or narrow and complex areas, which increases the safety of the manned submersible; it can photograph the work of the manned submersible from the periphery The situation can be pre-checked in the bottom area of ​​the manned submersible in unknown waters, and it can also check the external faults of the carrier propeller and carrier; in an emergency, it can also trigger the emergency dumping mechanism of the manned submersible to help The human submersible is out of danger, and it is also of great significance for the detailed observation of local areas such as deep sea hydrothermal fluid. Son-mother submersible is the future development trend It is reported that the miniature ROV prototype developed by Shenyang Automation can cooperate with manned submersibles and complement each other to improve the safety of manned submersibles, and further promote the application of manned submersibles in China, thereby achieving good economic and social benefits . At the same time, the micro ROV also has important reference and reference value for the development of other remotely mounted submersibles. "The research results can be extended to many application fields, not just limited to underwater robots. In China, this method will become the future development trend." Wang Xiaohui said. According to reports, the miniature remote control submersibles mounted on the body of the manned submersible to form a sub-mother working mode have been used in many international applications. For example, the miniature ROV carried on the Russian submersible "Peace 2" has successfully completed several shipwreck inspection missions and achieved good results.
