Research and development of an acoustic modem for underwater bio-mimetic fish robots

Abstract

Acoustic communication is one of the essential technologies for many promising underwater systems. In this paper, we focus on the research and development of an acoustic modem for a real-time water quality monitoring system using bio-mimetic fish robots. Challengeable issues from the viewpoint of acoustic communication for the application are first classified and then the detailed study is conducted to meet each design criterion. Also, the implemented modem hardware is verified in terms of functionality and performance through experiments in a lake and a river.
