| Outline of Final Research Achievements |
The purpose of this study is to analyse the functional mechanism of the lower limbs, more than the development of pure robotic bipedal walking. The robotic walking simulator firstly started the functional reproduction of the loading responce phase according to the explanation of the rocker function, in which the knee joint is initially in bending position at the heel contact. Muscles in lower limbs were represented by springs with serially connected tendons. At present state, 3 motors were arranged in the one limb, and pulled the tendons in an adequate trajectories. From the loading responce, each muscle spring sequentially functions to reproduce the walking phase of the rocker function theory. The musculoskeletal walking simulator succesfully reproduced the human walking trajectory in a 2 dimentional walking pathway. The results of this study proved the relationship between the rocker function theory and the musculoskeletal construction of the lower limb of Human.

| Academic Significance and Societal Importance of the Research Achievements |
もし、機能が本当に理解されているならば、それを人工系で再現できるはずである。本研究では下肢リハビリテーションにおいて一つの指標とされるロッカーファンクション理論を用いて、下肢筋骨格構成を再現した、筋骨格型ロボット歩行シミュレータを実歩行させることに成功した。これにより、ロッカーファンクションを念頭とした歩行リハビリが力学的にも十分に説明がつくこと実証された。
