Even if an environment varies, a desirable stable movement continues in the motion generating the interaction between body and environment, e.g., the walking of human and the other animals, the flutter of bird and insect. Therefore the learning according to the physical characteristic of body and the broad adaptive ability for various varieties like wind are required. Our study focus on adaptive ability that can be realized as the stabilization phenomenon called “entrainment” on the nonlinear dynamics like chaos. By observing flying behavior of butterfly, we can show that it is possible to realize entrainment phenomenon by information processing or neural network. Our goal is to fully understand entrainment phenomenon base on interaction between flying behavior of butterfly and environment.
