Biomimetic study of diving beetle robot propelled by alternating magnetic field

Abstract

The purpose of the present paper is to develop the micro swimming robot. The swimming behavior of diving beetle was analyzed by a high speed video camera system. Based on the kinematic analysis of insect swimming, a swimming robot propelled by the magnetic torque was developed. The robot system is composed of a NdFeB magnet and alternating magnetic field. It was found that the swimming velocity of robot depends on the frequency of magnetic field.
