Abstract: In this paper, the alloy sheet is simulated as the framework of the fishtail of fish-like robot, the giant magnetostrictive material, which is attached the sheet, as the muscle of the fish and the external magnetic field as the nerve to control the swing of the fishtail. A model of the robot is presented for vibrational equations of the fishtail. Based on the equations, result shows the relationship between the starting speeds and frequencies of the external magnetic field. At the same time, the distributions of giant magnetostrictive material and thickness of fishtail are discussed and the optimizing structure is given.
