The Parrot Sky Controller is an add on feature for the Parrot Bebop that docks a users tablet or smartphone and extends the range or the drone from about 600 meters to 2 kilometers.
The controller has a docking station for a tablet and once it is connected can be used to pilot the Bebop Drone using its two joysticks. Attached to the top of the controller is a large wing shapped antenna. 4 WiFi antennae inside help to maintain a strong connection between the Bebop Drone and the Sky Controller.
Perhaps the craziest feature when using the Sky Controller is the ability to connect an Occulus Rift VR headset. When connected, the Occulus will receive near real time video from the drone and a combination of head movement and joystick control will fly the device.
