TJ-FlyingFish was jointly developed by a team of scientists from the Shanghai Research Institute for Intelligent Autonomous Systems under the Tongji University and the Chinese University of Hong Kong.
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.
Possible applications include resource exploration, search and rescue missions, and engineering inspections.
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.
The quadrotor is equipped with a cross-domain positioning and navigation system consisting of GPS, inertial measurement unit, depthmeter and mini Doppler velocity log, which enables autonomous control during its amphibious journey.
