These tiny drones can lift 40 times their own weight

If you ask these tiny drones, "Do you even lift, bro?" you will get a resounding yes. Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and Stanford University have developed a line of small flying bots that can move objects that are 40 times their weight. The drones, called FlyCroTugs (short for "flying, micro tugging robots"), are equipped with a system of winches, adhesives and microspines that allow the tiny crafts, which weigh just a few ounces each, to latch onto just about anything. The winch is one of the few immovable parts of the highly customizable drone -- just about everything else about it can be modified for a given scenario. The grippers can be moved around depending on the landing surface, and the drone can take on additional accessories like wheels when a job calls for it.
