However, with the advancement of technology, drones were later customized into different forms for many commercial applications. These assistance have brought enormous benefits to humanity, including understanding tragic situations, searching for missing persons, creating 3D maps, surveying landscapes, wildlife protection, pipeline inspections, traffic monitoring, weather forecasting, firefighting, agriculture, photography, video production, and academic projects.

The cost of drones depends on their size and functionality. The price of a mini version of a handheld drone may be less than $100, while a military grade drone that can be carried in a backpack may cost tens of millions of dollars.
