Outline of Final Research Achievements	The higher field magnetic resonance imaging system has been introduced in clinical field. It is expected to be applied not only for diagnostics but also therapeutics. Although the　great advantage has been achieved by higher static magnetic field, it becomes difficult to use the device having metallic parts or wire by high frequency magnetic field. In this work, the use of laser-induced bubble as a driving source for motor actuator has been proposed and the principle confirmation experiments performed for investigating the possibility.
Academic Significance and Societal Importance of the Research Achievements	電気配線を用いないモータ・アクチュエータは現時点では空気圧駆動のものに限られている。ロボット・マニピュレータ等を構成するには、フレキシビリティの優れる配線系統の実現と実用的な応答特性が求められ、レーザーによる駆動方式はその可能性を有する選択肢であると考えられる。
