Heavy Mini Drone!

Drones usually cannot lift more than their own body weight. This makes their utility for something like search and rescue problematic because even if they found a stranded person for example, they couldn’t lift them out of their predicament. Now, however, a mighty mini drone has the capability of lifting as much as four times its own weight. The clever device uses grappling hooks inspired by gecko feet to grab hold of an object with a wire cable. Once attached, the drone spools-off the attachment wire until it lands and anchors on a safe perch. When secure, it winches the package to safety.
