| Outline of Final Research Achievements |
We proposed a method to design a lightweight deployable bar structure by converting the well-known rigid-origami pattern. By arranging various hinge joints effectively, it is possible to generate a mechanism with a small degree-of-freedom. It is also possible to generate a cylindrical curved surface structure by changing the member arrangement position.
As a method of designing a new mechanism that changes its shape in a designated direction, we formulated an optimization problem of placing hinge joints having a rotation axis at an arbitrary angle on the member end of an arbitrary shaped three-dimensional framework. In addition, we presented a method to evaluate the order of mechanism by judging the conditions for existence of higher order terms of mechanisms.
