Outline of Final Research Achievements

This research verified the motion characteristics of a fish-like robot encapsulated by a flexible plastic film under high-pressurized environment. To verify the motion of the fish-like robot, the position of transition of an actuator and a fin were measured using a camera centered onto the transparent case. Additionally, we modeled geometrically the fin motion under assumptions that the film enables to be inflected but not to be extended during the motion. In this model, we also assumed that the film did not slip with the components including the fin during the motion. Based on the model and several experiments, we confirmed that an appropriate volume of the insulating fluid was needed to move the fin.
