China Shipbuilding Heavy Industry 705 successfully developed robot prototype
Recently, the 750th Research Institute of China Shipbuilding Industry Corporation completed the remote control underwater vehicle prototype development and successfully carried out the pool verification test. The experimental results show that the underwater robot's underwater control, water surface control, depth-orientation and dynamic positioning, multi-channel video real-time transmission and other functions meet the development requirements, and realize the key technology verification stages of control, control, power supply and communication. The goal, the development of the "remote control underwater robot" project has made significant progress.
As the overall technology research institute of China's underwater equipment, the remote control underwater robot developed by 705 is a multi-propeller vector control, water-powered open-frame small-cable underwater observation vehicle, which is an advanced water. The special operation equipment has broad market prospects. The project was established in June 2013. After six months of hard work, the project team completed the program and engineering design, and successfully developed five self-developed units including control, observation, energy supply, structure and land control. A complete set of functional verification prototypes, including retractable/transporting devices.
In the project development process, the 705 project team further strengthened technical innovation and boldly adopted a number of new technologies. Through group control and mutual coupling of the propellers, the navigation attitude was stabilized and the control requirements were simplified. Buoyancy is rationally distributed, achieving good fluid dynamic layout and balance weight parameter layout, which reduces the overall quality; through multiple safety protection design, it realizes stable power transmission in complex environments. On the basis of multiple simulation analysis of control algorithm and fluid dynamics, the project team used the virtual simulation system of foreign wire diameter for the first time to simulate the whole process of underwater navigation of the prototype. At the same time, it carried out watertight pressure and control half. A large number of performance verification tests, such as physical simulation and pool actual navigation.
The successful development of the remote control underwater robot prototype not only marks the R&D capability of the 750 vector control, open-frame and remote-controlled underwater robot systems, but also opens up new technical fields for the open-type underwater vehicle in China. And the market for robotic systems and their ancillary equipment under the use of civilian water, providing an observational and experimental platform for various underwater technology research.
