| Outline of Final Research Achievements |
The purpose of this study was to investigate mathematically a control mechanism on traveling wave pattern due to musclular contraction in gastropods' crawling locomotion. Bifurcation phenomena of two locomotion styles, direct wave and retrograde wave, were observed in numerical calculations with our previous model of spring mass system, which is discribed the mutual interactions between the muscular contraction wave and dynamic viscoelasticity of the mucus. To understand friction control, we also performed a basic experiment of transition of friction control on crawling locomotion in gastropod. In the process of builing a mathematical model with two friction control, lifting pedal up or the mucus, we verified a fundamental common mechanism on proportion regulation in a swarm of self-driven particle.
