The PIV can be used to measure the flow field in the wind tunnel, and is conducive to analyzing the shape design of the bionic robot and the fluid related characteristics. The laser measurement system is a non-contact laser imaging flow field measurement method, which can obtain 3D flow field distribution information, which is helpful for in-depth analysis of experimental results. Intelligent current and wave making system can generate a steady flow field of 0-1m/s and various waves, which can be used to test the flow field characteristics of underwater bionic robots and underwater robots, and to study intelligent control methods in wave environment. The high-pressure test system can carry out pressure test on deep-sea equipment or core parts with working depth of 0-1500 meters, develop and test the core pressure resistant parts of deep-sea robots, and test and monitor the whole process of deep-sea underwater laser manufacturing. The underwater multi-sensor platform has DVL, various sonar, underwater camera, pressure sensor, etc., which is used to develop deep-sea intelligent underwater robot and serve the national marine economy and defense.The high-power laser processing system mainly includes laser light source, double optical path shutter, operating optical fiber, underwater laser welding head, laser cladding head, water cooler and supporting spare parts. The system can be used for laser repair rapid prototyping and underwater laser welding manufacturing of various materials.
