Engineers at Harvard University have created a millionth-scale automobile differential to govern the flight of minuscule aerial robots. Their new approach is the first to passively balance the aerodynamic forces encountered by these miniature flying devices, letting their wings flap asymmetrically in response to gusts of wind, wing damage, and other real-world impediments. “The drivetrain… »
