Scientists at the University of Pennsylvania in Philadelphia have developed a quadrotor that can imitate the way that an eagle grabs prey.
Above, a slow motion of the process.
They learned the small unmanned aerial vehicle (UAV), to grab objects in mid-flight, just like an eagle.
“Inspired by the way a bald eagle swoops down to seize a fish from the water with its claws, Justin Thomas and colleagues at the University of Pennsylvania in Philadelphia have developed a fast-acting, talon-like gripper for a small unmanned aerial vehicle (UAV).
When the team studied the eagle’s behaviour, they noticed that the bird employed a useful trick to buy more time to grab its prey. The eagle would sweep its legs and claws backwards as its talons closed on a fish, so there was no need to slow down.”
