So you can see this robot going at about three meters per second, which is faster than walking speed, coordinating its arms, its claws and its flight with split-second timing to achieve this maneuver. In another experiment, I want to show you how the robot adapts its flight to control its suspended payload, whose length is actually larger than the width of the window. So in order to accomplish this, it actually has to pitch and adjust the altitude and swing the payload through. But of course we want to make these even smaller, and we're inspired in particular by honeybees. So if you look at honeybees, and this is a slowed down video, they're so small, the inertia is so lightweight --
