EAPSI:Leaping Out of Water - Fabrication of a Bio-Inspired Robotic Jumping Copepod

桡足类是小型甲壳类动物（约2毫米），触角很长，几乎栖息在所有的水生系统中。一些桡足类物种能够跳出水面以躲避捕食者。这种跳跃行为令人印象深刻，因为这种小尺度的生物通常很难打破水面。为了理解跳跃机制，将设计和建造一个生物启发的机器人来模仿跳跃的桡足类动物的运动。该项目将在首尔国立大学进行，由生物流体力学和微流体学领域的专家Ho-Young Kim博士指导。 这个项目的目标是创建一个生物启发跳跃机器人的运动学和流体动力学的基础上跳跃桡足类？的空中逃生机制。通过确定机器人产生的力和计算产生的流场，将获得对桡足类的更深入的了解。粒子图像测速（PIV）和力测量实验将在一个制造的天线划船机制，以可视化的速度流场和了解在不同尺度的作用力进行。然后，一个自我维持的桡足类机器人将制作模仿逃生机制的参数空间的基础上启发的性质。这些测试将提供更多的洞察力的必要力量，以克服表面张力和相关的流场周围跳跃桡足类。东亚和太平洋夏季研究所计划下的这个奖项支持美国研究生的夏季研究，由NSF和韩国国家研究基金会共同资助。

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.
