These drones will follow the person who is wearing the GPS device and thus will be able to shoot the athlete wherever he goes. The GPS device transmits your location to the flying drone which will easily locate you. The athlete will have to specify the height at which the drone is to fly.
The problem that is associated with the “follow me” technology is that it does not pay heed to the obstructions in the way of the drone. A drone is a machine that needs instructions for everything it does. It does not have brains of its own which is why it is extremely important that there are no obstructions present in the drone’s follow-me flight path.
