Nicole Sharp<p><strong>Swimming Like a Ray</strong></p><p>Manta rays are amazing and efficient swimmers — a necessity for any large animal that survives on tiny plankton. <a href="https://doi.org/10.1126/sciadv.adq4222" rel="nofollow noopener noreferrer" target="_blank">Researchers have built</a> a new soft robot inspired by swimming mantas. Like its biological inspiration, the robot flaps its pectoral fins much as bird flaps its wings; this motion creates vortices that push water behind the robot, propelling it forward. For a downstroke, air inflates the robot’s body cavity, pushing the fins downward. When that air is released, its fins snap back up. With this simple and energy efficient stroke, researchers are able to control the robot’s swimming speed and depth, allowing it to maneuver around obstacles. Flapping faster helps the robot surface, and slower flapping allows it to sink. (Living manta rays also sink if they slow down.) Check out the robot in action below.
