Drones are useful in countless ways, but that usefulness is often limited by the time they can stay in the air. Shouldn’t drones be able to take a load off too? With these special claws attached, they can perch or hang with ease, conserving battery power and vastly extending their flight time.
The claws, created by a highly multinational team of researchers I’ll list at the end, are inspired by birds and bats. The team noted that many flying animals have specially adapted feet or claws suited to attaching the creature to its favored surface. Sometimes they sit, sometimes they hang, sometimes they just kind of lean on it and don’t have to flap as hard.
As the researchers write:
In all of these cases, some suitably shaped part of the animal’s foot interacts with a structure in the environment and facilitates that less lift needs to be generated or that power flight can be completely suspended. Our goal is to use the same concept, which is commonly referred to as “perching,” for UAVs [unmanned aerial vehicles].
“Perching,” you say? Go on…
We designed a modularized and actuated landing gear framework for rotary-wing UAVs consisting of an actuated gripper module and a set of contact …read more
