BionicOpter Dragonfly Drone

Engadget reports: [edited]

Festo's 17.3-inch long dragonfly drone can flutter through the air in any direction, and even hover, just like its biological inspiration. Its four carbon fibre and foil wings beat up to 20 times per-second, propelling it through the air as if it were swimming rather than flying.

Piloting the robo-bug is achieved through a smartphone app, but an on-board ARM-based microcontroller makes small adjustments to ensure stability during flight.
