We don’t know either we should be shocked or vivacious. We’ve only come opposite a video demo from a University of Pennsylvania’s LEARN Lab that shows an unconstrained quadrotor helicopter behaving “precise aggressive maneuvers.” And trust us when you contend, zero in the foregoing judgment is an exaggeration — a thing moves with the speed and beauty of an indignant bee, whilst accompanied by the perfectly ominous bemoan of the small engine. See this work of scientific art in motion after the break.
