Rutgers University has built a drone that can swim as well as it can fly, as you can see in the video above. The “Naviator,” as they’ve called it, has sparked the interest of the US Navy, which recently funded the project with a $618,000 grant. Rutgers engineers say they will use the money to make it stronger and faster. They also need to find a way to wirelessly communicate with it, since radio waves don’t travel well underwater. Right now, the drone is tethered to its controls.
