Remote Controlled quadcopter drone equipped with video camera that sends a live feed to Virtual Reality goggles.
The Virtual Reality goggles have multi-axis orientation sensors, and they control the orientation of the camera on the drone, i.e. if you wear the VR goggles and turn your head to the right, the camera will rotate to the right, etc.
