Delivery drones transport medicines, parcels, groceries, food, and other homecare products. These drones’ delivery operations are gaining widespread importance in last-mile delivery because of their accuracy, environment-friendly operations, shorter delivery time, and lower operational cost than traditional methods. According to some calculations, the operating costs for a drone delivery service are 40% to 70% lower than a vehicle delivery service. Additionally, the COVID-19 pandemic has made the implementation of this alternative, safe and contactless delivery model happen even faster. Despite their speed and convenience, however, there are some current challenges of using drones to deliver products. The first challenge is the question of airspace. The skies above urban areas are already congested with so many commercial aircraft and helicopters that there might not be enough room up for hundreds or even thousands of delivery drones. Delivery companies will need to prove that these drones won’t pose any threat to people or private property. Another concern is security. Since the drones will be traveling independently, the computer system that controls them will need to be protected from hackers and thieves. A drone controlled by a hacker is the biggest danger to buildings, people and other aircraft. And what happens when a malfunctioning drone falls from the sky?
