Outline of Final Research Achievements |
The goal of this research was to establish a method for simultaneously exploring the robot's motion and body by extending the optimization-based robot motion generation method. First, we developed a motion generation method that uses sequential quadratic programming to determine a time series of robot posture sequences that realize a given task. Second, we parameterized the robot's body structure as variable link lengths and joint axis orientations, and developed a method to determine the body structure that minimizes indexes such as joint torque by simultaneously optimizing both parameters describing the motion and the body structure as design variables in the motion generation method described above.

Academic Significance and Societal Importance of the Research Achievements |
本研究は,ロボットの身体の設計とロボットの動作の生成という別々に扱われることの多い2つのプロセスを同時に扱うための技術を確立することを目的とした.これにより,実行するタスクに応じて身体サイズや消費エネルギーの観点でより効率的なロボットの身体と動作を生成することで,ロボットが実社会に適用される際にその有用性を向上させることに寄与すると考える.本研究成果は,人型ロボットのアームの関節配置の探索から工場を模した環境でのマニピュレータ配置の探索まで,本技術が様々なスケールの問題に適用可能であることを示している.
