The
RoboSwift, built by researchers at the Delft University of Technology,
is among the first flying machines with a "morphing" wing sweep. As
you'll see in the video below, its wings reduce in surface area when
pulled back to limit drag, the way the wings of actual fast-flying
swifts do. Unlike the real birds, however, the RoboSwift is designed to
spy on you.
Inside its small body (20" wingspan), there's a low-resolution
wireless camera. The idea, already thought to be a good one by Dutch
police, is that RoboSwift can be used to surreptitiously hover over
crime scenes or football riots. People below, if they did look up,
would only to see a soaring, swooping bird of no consequence.
