Forget Mainstream Drones, The Clawdrone Perches Like A Bird

Drones constantly have to be on motion when they are being used however there is a new drone in town, that is made to behave like a bird.

The clawdrone, which has specialized 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 modules that are mounted on the gripper’s fingers.

This modularization substantially increased the range of possible structures that can be exploited for perching and resting as compared with avian-inspired grippers.

Instead of trying to build one complex mechanism, like a pair of articulating feet, the team gave the drones a set of specially shaped 3D-printed static modules and one big gripper.

The drone surveys its surroundings using lidar or some other depth-aware sensor. This lets it characterize surfaces nearby and match those to a library of examples that it knows it can rest on.
