For Amazon, small drones can do the heavy lifting.
That’s according to a patent filing published Jan. 19 in which drones team up to deliver larger orders. The mission describes a “collective” drone or unmanned aerial vehicle (UAV) that will transport a variety of items beyond the capabilities of a single drone.
“For example, instead of using one large UAV to transport a larger or heavier object, several smaller UAVs can be linked together to form a collective UAV used to transport a larger or heavier object,” the filing states .
