Outline of Final Research Achievements

This study proposes a novel configuration method of scissor mechanisms for the deployable structure with one degree of freedom. This method, which combines planar scissors to create a polyhedron as a basic unit and connects several units in a specific manner, has practical applications in creating complex space structures. Unlike conventional scissors-like elements that connect the intermediate parts of two members with a pivot hinge, our proposal utilizes composite scissors-like elements composed of an even number of two or more members. This approach enables the creation of two main structures: a multi-faceted prism scissor mechanism that can fill space by connecting the end parts, forming a grid-like three-dimensional structure, and a surface-deploying curved surface scissor mechanism.
