Two teams of five drones each, protected by spherical carbon frames, face off at the Consumer Electronics Show in Las Vegas. As part of the 'drone soccer' demo, both teams attempt to fly their 'striker' drone through a goal post suspended 3.5 meters above the pitch. Ro Sang Heub, President of the Federation of International Drone Soccer Association, says he wants to see it become 'one of the major sports played by everybody.'
