Drone racing is a motorsport where participants operate radio-controlled aircraft equipped with onboard digital video cameras, with the operator looking at a compact flat panel display or, more often, wearing a head-mounted display showing live-streamed image feed from the aircraft. Similar to full-size air racing, the goal of the sport is to complete an obstacle course as quickly as possible. Drone racing began in 2011 in Germany with a number of amateur drone controllers getting together for semi-organized races in Karlsruhe.
