739 Analysis of Swimming Ability of Blue Fin and Its Application to the Robot
Details
The swimming motion of Tuna type fishes has excellent ability for its speed and efficiency. This paper shows an analysis toward the swimming motion of Blue Fin Tuna with some experimental data. This analysis is based on the simple wing theory, because our primary target is not to know how it works but to decide how to actuate the robot fish. In the 1^<st> report, we assumed that the tale fin angle must be controlled according to the water inflowing angle. So, in this paper, an accurate model of real tuna tale fin is used for experiment to measure the lift and drag force while going forward into the water. By using these data, the relationship between needed actuating force for tale fin and created propulsive force by tale fin.
