    <p>Several animals such as snails and earthworms exhibit crawling locomotion by propagating the bodily wave of expansion and contraction to adapt to various environments. In this locomotion, not only expansion and contraction of the body but also friction with the environment is considered to be an important factor. However, existing studies has not sufficiently integrate peristaltic movement with friction control. Therefore, in this research, we propose a decentralized control of crawling locomotion that well-integrates peristaltic movement with adaptive friction control, and simulation results represent that a crawling locomotion with high environmental adaptability was realized.</p>

  • Mechanism and Control on Adhesive Locomotion in Gastropods

    <p>This study aim to investigate the mechanism of adhesive locomotion in gastropod. It has been reported by previous study that the significant factors of locomotion mechanism are "propagation of muscular waves" and "interfacial friction against the ground". Interfacial friction has been considered to be controlled by lifting the pedal up, or dynamic viscoelasticity of mucus. To lift pedal up in appropriate timing, complex signals from the center would be necessary although the mechanism of lifting is simple in kinetics. This study focused on the hypothesis of dynamic viscoelasticity of mucus reported by Denny from the point of view of automatic frictional control similar to the mechanism of locomotion in earthworm. Based on the matter of previous study, a simple mathematical model which captures essential factors obtained by qualitative observations is proposed, and the physical parameters in the model are estimated by quantitative results from careful experiments. It has been verified by numerical calculations with the model that the mutual interaction between flexible muscular contraction waves and nonlinear dynamic viscoelasticity of the mucus can achieve an efficient locomotion. The important result in this study is that two locomotion styles, direct wave and retrograde wave, which has been understood by different mechanism, can be realized by the same mechanism.</p>

    カタツムリなどの腹足類では這って移動する際に腹足に動的な2次元パターンが出現し、またイカ類などの頭足類では、擬態行動や個体間のコミュニケーションの際に表皮に動的な2次元パターンが出現し、そのパターンが瞬時に変化する。本研究では、これら腹足類や頭足類などの軟体動物においてはパターン形成が筋収縮によって実現されていることに着目し、筋収縮パターンの制御方法を探ることで、腹足類の這行運動における運動制御メカニズムを系統的に理解し、工学応用の基盤を確立することを目的としている。
    目的の達成に向けて、平成30年度は、(課題I) 1次元信号から2次元パターン形成のための数理モデルの構築を行い数値シミュレーションによりモデルの検証を行った。まず、1次元のバネ質点系に対して、中枢から信号を想定して、FitzHugh-Nagumoモデルにより周期的なパルスによる入力の有無によって、筋収縮により色素胞が拡大・縮小し、表皮パターンを変化させた。次に2次元のバネ質点系に対して、一定の外部刺激(イカ類の場合は視覚情報)がFitzHugh-Nagumoモデルに入力され、それを元に筋収縮を行った結果、パラメータによって、ストライプやスポットなどの2次元非一様パターンをバネ質点系モデルの数値シミュレーションで実現した。しかしながら、この非一様パターンは反応拡散系によるものであり、軟体動物の神経システムを模倣できているとは言い難い。今度の課題として、軟体動物の神経システムにおいては、中枢からの神経が末端では放射状に繋がっていることを考慮して、信号入力に中距離相互作用を導入する予定である。

    It has been known that cephalopods can change their body surface patterns rapidly and dramatically, and these body patterns are thought that used as a linguistic tool in the situations of communication between the individuals because of their high ability of learning and memory. The purpose of this study was to understand the linguistic meanings of body patterns in cephalopods. Hence, we suggested a behavioral experiment of social situation for cuttlefish, Sepia pharaonis and Sepia latimanus, then investigated the variations of their actions and body patterns. From appearance frequency of that actions and body patterns we discuss the statistical feature of the variations.

    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.
