By living and moving in groups, fish can gain many benefits, such as heightened predator detection, greater hunting efficiency, more accurate environmental sensing, and energy saving. Although the benefits of hydrodynamic interactions in schooling fish have drawn growing interest in fields such as biology, physics, and engineering, and multiple hypotheses for how such benefits … [Read more...] about RoboTwin: A Platform to Study Hydrodynamic Interactions in Schooling Fish
