Take a quick look at the TJ-FlyingFish, and you might think it’s a typical quadcopter drone. Watch it in action, though, and you’ll discover it’s an amphibious drone, equally at home in the air and under the water, is capable of moving seamlessly between the two, and can operate entirely autonomously in both environments. The new drone, jointly invented by CUHK Professor Ben M. Chen and his research team, promises to revolutionise a range of tasks, from surveying to remote sensing to search and rescue.
