Chinese researchers develop amphibious 'flying fish' drone

Researchers have developed a prototype of a quadrotor that can both fly in the air and swim underwater, making it suitable for a wide range of applications.

Dubbed TJ-FlyingFish, the aerial-aquatic quadrotor weighs 1.63 kg with a wheelbase of 380 mm.

It adopts special designs in the propulsion and thruster configuration to cope with different fluid properties of water and air, making it capable of hovering in the air for six minutes or swimming underwater for about 40 minutes.
