In 2021, researchers analyzed the anatomy and behavior of a tiny American parrot called a parrotlet and peregrine falcons, two species known for their expert footwork. They then designed SNAG (the Stereotyped Nature-Inspired Aerial Grasper)—a pair of jointed legs attached to feet with jointed talons that automatically close around any object they encounter, be it a dowel, branch, or tennis ball.
