Inspired by spiders and wasps, these tiny drones pull 40x their own weight – TechCrunch

If we want drones to do our dirty work for us, they’re going to need to get pretty good at hauling stuff around. But due to the pesky yet unavoidable restraints of physics, it’s hard for them to muster the forces necessary to do so while airborne — so these drones brace themselves against the ground to get the requisite torque. The drones, created by engineers at Stanford and Switzerland’s EPFL,
