Intelligent bionic jellyfish robot for shallow water quality monitoring

Abstract

With the development of human society, environmental problems have gradually become a hot issue of concern worldwide. Among all environmental problems, water pollution is one of the most important ones. Water pollution threatens the survival and development of human society. The good or bad condition of water quality is directly related to the quality of life of thousands of families, animals, and plants. Based on the above background, this project team designs a bionic jellyfish that can imitate physical movement through mechanical structures. We use the characteristics of the Disc reciprocating mechanism, Triangular three-link mechanism, and Slotted cam push rod telescoping mechanism to achieve different ways of jellyfish movement. For the bell-shaped body of the bionic jellyfish, we use waterproof and flexible material to make it to protect the internal mechanical structure and control unit. For the experiments, we use ANSYS 2022 to simulate the stress deformation of two critical parts of the jellyfish robot. The bionic robot’s various advantages, like small size, low energy consumption, and no environmental pollution, can monitor offshore and rivers’ water quality to better protect fish and other aquatic organisms. Moreover, it is very promising for science and education as well.
