4Dプリンタで作製した磁場駆動ワーム型ソフトロボット

<p>In this study, we proposed a new manufacturing method for worm-type soft robots with 4D-printing and demonstrated an actuation of the structure. Muscular contractions of a worm cause friction between the body and a contact surface, therefore, a worm moves forward. We designed a small worm-shape robot that proceeds in the same principle. We employed magnetic elastomer as a material and fabricated a soft robot that drove under a magnetic field. We utilized a 4D-printing system, which can not only produce a three-dimensional object but also set magnetic anisotropy at each portion of the structure. We can develop understanding about behaviors of flexible organisms through fabricating applications of biomimic structures.</p>
