AR Drone is a quadcopter and is controlled primarily by an Apple iPhone, iPod touch, or iPad units. An open API allows for development of applications.
The control system is based on an ARM prosessor and Linux operating system. Control signals go through a 802.11b/g/n wireless IP connection. Two cameras provide a live video stream to the display on the remote. The AR.FreeFlight app can be downloaded from the App Store.
