| Outline of Final Research Achievements |
In order to realize the function of the flexible shape change necessary for the medical micro robot which minimizes the damage of the living tissue as much as possible, the basic propulsion mechanism in fluid based on the contraction structure which is one of the hypotheses of Euglena's motive force developed. This mechanism consists of multiple elastic telescopic mechanisms arranged in a grid and an elastic frame, and it was possible to change the movement form of the whole by changing the movement pattern of the telescopic mechanism. As the propulsion characteristics of this mechanism, the change of thrust force, average thrust force and flow field in one movement cycle in water and highly viscous fluid were evaluated，in addition it was shown that it is possible to generate the necessary propulsion force for self-propulsion.
