空気圧ゴム人工筋を用いた柔軟なアクチュエータの開発
人に優しく,かつ,軽量・柔軟なアクチュエータを実現するために,空気圧ゴム人工筋を用いた駆動制御装置を開発しています.空気圧ゴム人工筋を用いた従来のアクチュエータは,人工筋内部の圧力を比較的に高い圧力状態にした制御装置が多く見られますが,柔軟性に欠けます.一方,本研究では,低圧域(2気圧程度)から高圧域(6気圧程度)までをカバーする動的モデルを同定し,柔軟性を調整可能な角度/トルク制御を実現する駆動制御装置(ユニット)の開発を目指しています.また,長期間使用によるゴムなどの経年劣化や故障検知の研究にも取り組んでいます.そして,使いやすいパワーアシスト装置やリハビリ機器の発展に繋がることを期待しています.
