Abstract
This paper is concerned with the locomotive characteristics and the structure dynamics of some arthropods. The locomotive motions of some insects were studied using a high-speed video camera system. The walking, jumping, and swimming movements of some arthropods were analyzed from the viewpoint of dynamics. The structural properties of some arthropod organs were also studied using a color 3D laser scanning microscope. Some functional principles underlying arthropod organ design were revealed by the microscopic measurements and movement analysis of arthropods.
