| Outline of Final Research Achievements |
Recently, we developed a genetical engineered bio-molecular artificial muscle which formed by light illumination and demonstrated the possibility of 3D printing of micro-robots using the bio-artificial muscle. Because the bio-artificial muscle only contract one-shut, it is not practical to use the artificial muscle as an actuator of micro-robots. In this study, we focused the oscillatory movement in the biological molecular motors and tried to built the artificial muscle including flagella motors. By using flagella motor purified from chlamydomonas instead of microtubule in kinesin/microtubule artificial muscle system which we have previously developed, the bio-artificial muscle with flagella motors was successfully formed.

| Academic Significance and Societal Importance of the Research Achievements |
微生物や昆虫などの生物は，運動・制御・知能を兼ね備えた究極のマイクロロボットといえる。これは分子レベルから構築された生体の複雑な分子システムにより実現しているが、その仕組みは未だ不明なところが多い。本研究では生体分子を再設計・再構築することを通して生体分子システムを理解し、さらに従来法でなしえない機械システムまたはマイクロロボットの構築を目指している。
