The Parrot AR.Drone was revealed at the International CES 2010 in Las Vegas along with demonstration of the iOS applications used to control it. Along with AR.Freeflight, the application designed for free operation of the drone, Parrot also released AR.Race, allowing users take part in solo games, or interact with other drones in combat simulations.
The airframe of the AR.Drone, constructed of nylon and carbon fiber parts, measures 57 cm (22 in) across. Two interchangeable hulls were supplied with the airframe, one designed for indoor and one for external flight. The indoor hull is made from EPP foam, and encases the circumference of the blades for protection. The outdoors use hull is made from lightweight plastic, and allows for increased maneuvrability. In total, the AR.Drone has six degrees of freedom, with a miniaturized inertial measurement unit tracking the pitch, roll and yaw for use in stabilisation.
