Title:
MULTI-JOINT FISH ROBOT CAPABLE OF RAPID ACCELERATION PROPULSION
Document Type and Number:
Japanese Patent JP2018075702
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-joint fish robot capable of rapid acceleration propulsion, which can maximize propulsion with respect to a swimming direction of the fish robot and minimize water resistance thereby improving swimming speed and energy efficiency.SOLUTION: A multi-joint fish robot capable of rapid acceleration propulsion includes: a main body segmented into a first body, a second body and a third body; joints connecting the corresponding bodies; and a caudal fin provided at an end portion of the third body. The fish robot swims while forming a curve by operations of the joints. The fish robot has a first occupancy ratio, which is the ratio of the length of the caudal fin to the full length of the fish robot with respect to a swimming direction, in which the fish robot swims, and the first occupancy ratio is from 0.15 to 0.35 inclusive.SELECTED DRAWING: Figure 1
