DIY Naval Drones: Floating Quadcopter
Multi-rotors have been well-received by hobbyists and even garnered some interest from the U.S. Navy. But up until now, these lightweight UAVs haven't mixed very well with water. The guys at Aquacopters have changed this with a water-proofed and ruggedized simple quad-frame. The ability to capture video above, on, and under the surface of the water with a single small drone creates an interesting range of options for hobby, scientific, commercial, or military use.
