Drones take a cue from wasps to manipulate objects 40 times their own mass
In a move inspired by natural engineering, robotics researchers have demonstrated how tiny palm-size drones can forcefully tug objects 40 times their own mass by anchoring themselves to the ground or to walls. It’s a glimpse into how small drones could more actively manipulate their environment in a way similar to that of humans or larger robots.
“Teams of these drones could work cooperatively to perform more complex manipulation tasks,” says Matt Estrada, a Ph.D. student in mechanical engineering at Stanford University. “We demonstrated opening a door, but this approach could be extended to turning a ball valve, moving a piece of debris, or retrieving an object of interest from a disaster zone.”
