The Japanese Ministry of Self-Defense has created a spherical flying bot that can fly at a speed of up to 40 mph and hover if need be. Not only is the spybot multi-talented, should it run into a wall, obstacle or human, it will roll to prevent damage. About the size of a soccer ball, it navigates via a single propeller and can be adapted to carry a camera. Each goes for about $1,000 and is only available in Japan for now.
