TJ-FlingFish it’s a special hybrid drone capable of flying through the air and swimming under water without having to replace the propellers, designed by a pool of researchers from the Research Institute for Intelligent Autonomous Systems in Shanghai together with Tongji University and the Unmanned Systems Research Group of Hong Kong University. In recent years, hundreds of drone models of various sizes and characteristics have come out capable of hovering in the sky and a smaller quantity for underwater use: this special proposal for now a prototype is able to embrace both environments and could find numerous applications mainly for professional use, but could also open up to smaller versions for the private public.
Flying and swimming drones have very different constructions as they move three-dimensionally in two environments with considerable differences between the two fluids, however the TJ-FlingFish project seeks to merge the two worlds with a model that can take off and move with agility in the air before resting on the surface of the water, go to the bottom and adjust the direction of the propellers to explore the depths without particular problems. As demonstrated in the video below, the prototype of this drone can operate almost seamlessly anywhere, naturally protecting all components via a special diving suit when immersed.
It can be seen from the video how the drone remains in its flight configuration with the propellers in a vertical position, while once landed, it rotates them in the opposite direction to push the device underwater: from that moment there is full freedom of action with the propellers that can move in any direction, also adjusting the speed as desired. It is possible at any time to return to the surface and take off again. Currently the battery of the prototype makes it fly for about 6 minutes and move underwater for 40 and can act autonomously without constant human control. What can it be used for? First in emergency and rescue situations as a scout for the search for missing persons in difficult conditions, but also for control inspections in environments where it is necessary to monitor structures above and below the water. While not a priority, it could also provide a pretty good proposition for unlimited, anywhere shooting.
