<ul><li>Cecilia Huertas Cerdeira and her team from the University of Maryland are designing a robotic fin inspired by the tail of a tuna fish to build better underwater drones.</li><li>The robotic fin will help the drone swim faster, turn more smoothly, and consume less energy than traditional propellers.</li><li>By mimicking the shape and movement of a tuna’s tail, the robotic fin can solve problems caused by current models that use propellers, such as creating drag, making noise, and scaring fish.</li><li>The bio-inspired design of the robotic fin could lead to faster, smarter, and quieter underwater robots, making ocean research and exploration safer and easier.</li></ul>
