China's first ocean-going fishery resources investigation vessel, the “Yaohangâ€, successfully completed its maiden voyage and recently returned home in Shanghai. The scientific expedition tour triumphed and the underwater robots carried by the "Shang Hang" were indispensable. Fully "showing" the "intelligence and intelligence" of artificial intelligence (AI), for submarine robots, it is a piece of cake to dive into the underwater environment for 600 meters to find out the environment of the fishery. After the robot arm is equipped, it can directly operate underwater. In fact, in the Shanghai Ocean University's laboratory, more "fantasy" underwater robot research has already taken shape. Among them, the machine fish with AI are good at lifelike bionics, and even the fish are not so easy to identify their "foreign" identities. "The robotic fish" each has wisdom With a wing-shaped pectoral fin and a slender tail like a whip, this manta is very realistic in appearance, but it is a real "agent." Since 2013, the research team led by Professor Qian Weiguo of Shanghai Ocean University has started the research of robotic fish. The first generation of "Peiyu No.1", despite its realistic shape, also overcomes technical difficulties such as visual obstacle avoidance in water, sensor information reception and output, but the cable drive still allows it to "open up flaws." Therefore, starting from "Pike 2", R & D entered the era of cable-free driving. “Our mechanical turtles have increased swimming with multiple degrees of freedom. The huge back shell can also carry a variety of sensors. The mechanical sea snake is 80 centimeters long and can shuttle freely through the river silt, which is equivalent to a bottom drone.†Qian Wei The country has introduced these AI works to journalists. In the 2017 OI China Underwater Robot Competition held this year, a variety of robotic fish from Shanghai Ocean University won the award, and Qian Weiguo also received the Outstanding Teacher Award.

With the robotic fish, the fishermen will be able to 'prescribe the right medicine.'†Qian Weiguo said. “The robotic fish can also assume the responsibilities of fishery exploration and underwater environment testing.†Whether or not these realistic robotic fish may be “ingested†by large-scale predation fish, Qian Weiguo said that it will be avoided through measures such as interfering with color. "secret agents" use a wide range of With the development of science and technology and the acceleration of human development of the ocean, underwater robots, especially highly-imitation robotic fish, have received increasing attention as an important means for humans to explore the ocean. “The ocean is the space where energy and biological resources have the greatest potential for development. With the development of human understanding and the development of the ocean, underwater robots are constantly developing.†Qian Weiguo said, “Water is the world of fish, human beings. The morphological characteristics are completely inferior to those of fish. Therefore, underwater robots mostly emulate fish forms and even exercise patterns, so that they can be easily mixed into fish schools."

They can rely on their own decision-making and control to efficiently complete scheduled tasks in a complex marine environment. “The cableless underwater robots have broad application prospects in the economic and military fields and represent the development trend of underwater robots. However, the relative lack of high-efficiency batteries is a bottleneck in the current development of cableless underwater robots.†Qian Weiguo said. In addition, Shanghai Ocean University has also developed AI high-tech products, such as shrimp and crab pond autonomous navigation feeding bait, with independent path planning and navigation capabilities, and the realization of self-introduction of feeding and water quality monitoring. Currently, it has been in Baoshan, Chongming and other farms. Applied and exported to countries such as Ecuador. Source: Xinmin Evening News
