| Research Abstract |
Adaptive behaviors observed in the true slime mold and bipedal locomotion systems have been studied. Recently, it has been reported that even single-celled organisms appear to be indecisive when confronted with an obstacle. In this project, the phenomenological model equation was proposed, and found that an on-off transition between refractory and activated state of chemical reactivity taking place at the leading edge plays a key role in the emergence of adaptive behavior. By investigating numerically the bipedal walking systems, it was found that the system shows an adaptive behavior by governing the dynamics of knee and hip joint by walking velocity.
