Outline of Final Research Achievements |
In this study, we developed a robot for which all body parts have variable stiffness and sensitivity. This robot is based on our previously developed robot arm with variable stiffness and sensitivity, which utilized the stiffness change of a shape-memory polymer based on the temperature. In this study, we improved and miniaturized shape-memory polymer parts such as artificial muscles and force and tactile sensors. Furthermore, we developed parts such as links and force sensors that utilize the jamming transition phenomenon and a shape-memory alloy. We constructed prototypes of the proposed robot arms and evaluated their performance.

Academic Significance and Societal Importance of the Research Achievements |
ロボットが柔軟なだけでなく、人間より優れた剛性・感度可変の要素を持つことは、これまでのロボットにはできなかった人間以上の巧みな動きを実現するための基盤となる。そのため、剛性・感度可変のロボットは、「ソフトロボット」の次のトレンドになり得る。また、全身に拡張することで介護・福祉・産業・医療などさまざまな環境で活用できるロボットのプラットフォーム・基盤技術を創造できる。
