The Daily Mirror reports that a video of flying robots, developed in a lab at the University of Pennsylvania, has captured more than 1 million viewers worldwide.
Not only are the "nano-quadrotors" able to levitate individually, they can also move in packs -- opening up the possibility of multiple formations and sequences.
They can also navigate spaces with obstacles, flip over and maintain position and carry out formation flying in a project that aims to replicate swarming habits in nature.
In a further demonstration of their remarkable capabilities, the drones are also seen swirling in an impressive figure of eight pattern.
