At first glance (and perhaps not too closely) it might seem like a real hummingbird, but it is the new spybot made by DARPA: this flying robot is equipped with a video camera capable of transmitting images from a distance.
The dimensions I am still excessive (but I'm very demanding): 16 cm of wingspan and 19 grams of weight. Yes, it's not a Boeing, and No, that's not all.
We'll see them fly, boys: and one fine day, we won't even see them more closely knot.
