Nowadays, drones carry packages in well-defined conditions and rural areas, but doing the same task in an urban environment is much more challenging. Tall buildings and existing communicational equipment in the urban environment cause electromagnetic interference, weakening positioning signals (GPS/GNSS) and thus can lead to more significant errors in localisation and autonomous navigation. In such conditions, an additional positioning method is required, and as most drones have an imaging camera, positioning based on machine vision is one of the better choices. A reliable drone package delivery in the urban environment should be able to detect obstacles and avoid any collision. Delivering a medicine package in emergencies inside a high-traffic area is an example of drone package delivery's advantage over traditional package delivery. Another practical application of drones is the regular inspection of equipment installed in inaccessible locations that are hard to reach. A professionally trained operator is needed to control the drone to take pictures of the equipment from different angles. The same procedure can be done automatically, resulting in the simultaneous use of several drones, higher speed, and more accuracy. This year, The FIRA Air Challenge consists of 3 significant challenges: the Autonomous Drone Line Follower, Emergency Delivery and Tower Inspection and FPV Drone Race.
