Overview of Progress in Development of the Bionic Underwater Propulsion System

With the development of science and technology, the development of underwater vehicles with many advantages such as low energy consumption, low noise, high propulsion efficiency and high mobility, and the exploration is the direction of science and technology, and also becomes a hot research field. This paper introduces the status of researches of three different motion modes of the underwater nature objects and analyzed the propulsion mechanisms of different bionic underwater systems and of the existing problems in the development of the bionic underwater propulsion mechanism. This analysis of the use the new materials, existing decisions in bionics and intelligent control technology can be used in the development and design of the bionic thrusters for underwater robots.
