Outline of Final Research Achievements

In recent years, the rapid development of three-dimensional printing (3-D printing) opens new technologies. On the other hands, the construction of actuator by 3-D printer is not realized, so that actuator parts will have to be assembled into the frame part fabricated by 3-D printer after printing. Recently, we succeeded in constructing an artificial muscle using motor proteins by UV light illumination similar to a 3-D photo printing. We also succeeded in the operation of millimeter scaled micro-robot using this artificial muscle. In this project, we developed ‘artificial muscle ink’ containing the motor proteins, and began to develop new techniques for the 3-D printing of actuator of micro-robot.

Academic Significance and Societal Importance of the Research Achievements

昆虫サイズのマイクロロボットの出現がさまざまな分野で期待されているが、実現にはアクチュエータの開発を含め様々な課題がある。特にその製造方法はマイクロロボットのボディが小型なため従来のロボット製造とは大きく異なる手法が必要となる。本研究では従来不可能であったアクチュエータ部位の3Dプリント技術の開発に取り組み、この問題の解決を試みた。
