VIDEO: A DRONE THAT TRAVELS UNDERWATER AND IN THE AIR...

A team at Johns Hopkins University has created a UAAV – an unmanned aerial-aquatic vehicle. Named after the creature that inspired it, the Flying Fish is capable of both fixed-wing aerial flight and underwater travel.

The Flying Fish can propel in the air and under the water by a single motor and propeller. The prop spins quickly while the UAAV is airborne, but then slows down to a more appropriate speed when it dives below the water's surface. It speeds up again as the vehicle is about to return to the air, providing sufficient thrust to launch it up and out of the water.

The ultimate idea for the Flying Fish is that is could fly autonomously at 48 km/h to a landlocked body of water, dive in to collect environmental data or perform reconnaissance using onboard sensors such as a camera, then fly back to its base of operations.

The Flying Fish can be seen in action, in the video below.
