Bionic Research and it’s Application of Artificial Lateral Line System

Abstract

Nowadays, lots of efforts have been made to develop new technology for navigation system of underwater vehicle with the increasingly improved requirements of precise positioning, obstacles-avoidance, energy-saving in locomotion and stabilization in response to turbulent currents. In nature, fish have a great ability to localize prey, school, navigate, rheotaxis, etc. using the lateral-line organ. The biological lateral line system has inspired the researchers’ efforts to artificial lateral lines for applications in underwater vehicles and robots. In this paper, the working mechanism of the fish lateral line system has been described. Then the research status both at biology and at mechanics on the artificial lateral line system at home and abroad has been reviewed. To make a comparison with acoustic navigation system USBL,The key technologies and developing tendency as well as potential applications are described. At last, an insight on the future research directions and route of artificial lateral-line system have been given.
