Copepods are small crustaceans (~2 mm) with long antennae that inhabit nearly all aquatic systems. A few copepod species are able to jump out of water to escape predators. This jumping behavior is impressive because creatures at such small scales normally have difficulty breaking the water surface. To understand the jumping mechanism, a bio-inspired robot will be designed and built to mimic the movement of the jumping copepods. This project will be conducted at Seoul National University under the mentorship of Dr. Ho-Young Kim, an expert in the field of bio-fluid mechanics and microfluidics. The goal of this project is to create a bio-inspired jumping robot based on the kinematics and fluid dynamics of a jumping copepod?s aerial escape mechanism. By determining the forces generated by the robot and the calculating the resulting flow field, a deeper understanding of the copepod will be gained. Particle image velocimetry (PIV) and force measurement experiments will be performed on a fabricated antenna rowing mechanism in order to visualize the velocity flow field and understand the forces acting at different scales. Then, a self-sustaining copepod robot will be fabricated to mimic the escape mechanism based on a parameter space inspired by nature. These tests will give greater insight on the necessary forces to overcome surface tension and the associated flow fields around a jumping copepod. This award under the East Asia and Pacific Summer Institutes program supports summer research by a U.S. graduate student and is jointly funded by NSF and the National Research Foundation of Korea.

桡足类是小型甲壳类动物（约 2 毫米），具有长触角，几乎栖息在所有水生系统中。一些桡足类物种能够跳出水面以逃避捕食者。这种跳跃行为令人印象深刻，因为如此小规模的生物通常很难突破水面。为了了解跳跃机制，将设计和建造一个仿生机器人来模仿跳跃桡足类的运动。该项目将在生物流体力学和微流体领域专家 Ho-Young Kim 博士的指导下在首尔国立大学进行。 该项目的目标是基于跳跃桡足类空中逃生机制的运动学和流体动力学，创建一款仿生跳跃机器人。通过确定机器人产生的力并计算产生的流场，可以更深入地了解桡足类动物。粒子图像测速（PIV）和力测量实验将在制造的天线划行机构上进行，以便可视化速度流场并了解不同尺度下作用的力。然后，将制造一个自我维持的桡足类机器人，以模仿基于受大自然启发的参数空间的逃生机制。这些测试将更深入地了解克服表面张力所需的力以及跳跃桡足类周围的相关流场。该奖项隶属于东亚和太平洋地区暑期学院计划，支持美国研究生的暑期研究，由美国国家科学基金会和韩国国家研究基金会联合资助。
