Variations of Tethered Drones
Although there are many ways to use tethered drones innovatively, some people only attach a tether and leave it alone. By doing this they are still able to avoid regulations set by the FAA. At the same time however, can cause a few issues when flying. If a drone is flying with only a fishing line attached the drone has a chance of tangling with the wire and falling. The best way to avoid these kinds of issues is to either change how the drone flies or the tether itself.
Tethered drones have many different variations that can affect how they fly. They can range from a standard drone with a fishing wire attached to a drone that’s been programmed specifically for tethered flight. An example this would be the Fotokite. This tethered drone was founded by Sergei Lupashin, a researcher in robotics with over 10 years of autonomous systems experience, to enable anyone to take quality pictures with drones regardless of experience. The way this worked was by eliminating the need for a remote controler and instead make their drone move accordingly to where the tether was. This allows for simple control that any novice can learn.
Another variation on tether drones is the tether itself. Cyphy Works, a company that builds UAVs for search and rescue missions as well as bridge inspections, developed a power system that tethers onto their drones to supply power for unlimited flight. The tether itself is made from a microfilament and the surprising part about it is that it’s comparable to a fishing line in size, but at the same time it has a high enough power output to power a drone. Cyphy Works also spools their tether as their drones fly to avoid the possibilities of it being tangled or caught on something.
