スケールの異なる微生物模倣型マイクロロボットの推進効率評価

抄録

We evaluated propulsion efficiency of micro-gel robot with two different propulsion method. We made flagellar robot and peristaltic robot that we have proposed, and compared an energy efficiency of them in order to consider which principle is more suitable for propulsion in micro-scale. These two types of robot were made of temperature-responsive hydrogel(PNIPAAm), and we actuated them by scanning light to heat the hydrogels. We fabricated these two types of robots with various characteristic length L and drove them by scanning light with a galvano scanning system. We evaluated the scanning speed of light which can drive robots with the fastest speed. Furthermore, we evaluated a propulsion efficiency (body/min) according to L and succeeded in get the results that suggests the flagellar robot is more suitable for propulsion in micro-scale.
