An Inspired Underwater Communication Robotic Fish for Aquatic Animals

Underwater communication robots are used in various employment such as underwater environment tracking, underpinning surveillance, military and ocean observation. There are three feasible means of underwater wireless communication technologies essentially electromagnetic (EM), optical communication and acoustic communication systems. But the underwater acoustic communication savors the advantages of being simple and powerful in water. This paper presents to design and performance of FPGA based underwater communication robot with simplest architecture for underpinning surveillance and toxic metal avoidance. The proposed communication robot is tested in underwater environment to validate robustness and reliability. The prototype of underwater communication robot can be achieving 10m range of communication in aquatic environment. A Field Programmable Gate Array (FPGA) established peculiar implementation is developed to detect the presence of toxic metals and other metallic pollutants present in the ocean using MI sensor for saving the life span of aquatic animals. The detected information from the Ultrasonic transmitter is send to the Ultrasonic receiver for the analysis. Once the presence of metal is detected by the MI sensor, metal remover of the robot unit collects the toxic pollutants and the same is unloaded at the base station.
