Design of Bionic Robots for Underwater Surveys

Underwater robots have already played an important role in the development of marine resources, marine environment monitoring, deep sea exploration and rescue, military applications, scientific research and human civilisation heritage protection and other fields. Underwater bionic robots make full use of the characteristics and behavioural principles of natural organisms, simulate the appearance, movement mode and perception mechanism of marine organisms, break through the weaknesses of traditional underwater robots, such as bulky structure of the mechanical frame, low efficiency of the movement, and greater interference from factors such as water currents and waves, and can better adapt to the complex marine environment, which has become the hotspot of research. Based on the principle of bionics, this paper puts forward a kind of underwater survey bionic robot around solving the difficulties of motion bionics and morphology bionics of underwater bionic robot, hydrodynamic problem of computational fluid dynamics, optimisation problem of underwater attitude control, and smoothness problem of motion in survey work. The underwater survey bionic robot designed in this paper can coexist harmoniously with the natural environment, can carry lightweight survey instruments to work underwater for a long time, and effectively carry out underwater resource data feedback, which has a very broad application prospect in the development of marine resources and seabed exploration.
