| Outline of Final Research Achievements |
This project proposes the use of tensegrity structures to realize modular structures with high-precision shape control systems. Although this structural style has many advantages over truss structures, its practical application has not progressed much due to the difficulty of design and fabrication methods.
Through the research period, we will construct a system that enables precise shape control with a simple configuration by incorporating an actuator using a magnetostrictive element in the tensegrity structure, and verify its effectiveness as a unit structure for modular structures through both numerical simulations and experiments. The verified results show that the developed system realizes a smart structure that simultaneously performs large deformation control and precision control.
