Abstract

To uncover the hydrodynamic mechanisms in free swimming fish schools, researchers have developed series of physical models, such as filaments in a flowing soap. To carry out these experiments with these apparatus, schooling robot fish should be fixed and swimming in a laminar flow. In this poster, we study the hydrodynamic features in a self-propelled schooling robotic fish using an online power detection module and automated speed tracking platform. Comparing to previous physical models, a novel physical apparatus is endowed with self-propulsion by body undulation, online power detection and automated speed evaluation. Using this platform, we test and compare the power consumption and velocity of each robotic fish swimming in a side-by-side configuration with different phase difference. We find that, for the robotic fish swimming in a school, one of them saves energy while the other consumes more. And there is positive correction between the power consumption and the swimming speed. For in-phase swimming, the schooling robotic fish exhibit the maximum efficiency. While for out-of-phase swimming, the robotic fish swim fastest.
