Aero/Aqua Biomimetics Lab (Hiroto TANAKA Lab)

About us

Our laboratory has started up in November 2015. We study biomechanics and fluid dynamics of flying / swimming animals aiming to create biomimetic small, agile, and safe aerial / aquatic robots. We also focus on biological micro structures of such animals and micro fabrication technologies for biomimetic components. Through these studies, we innovate biomimetic mechanisms possessing biological softness and micro structures.

Recruitment
