Unmanned Aerial Vehicles

Definition

Unmanned Aerial Vehicles (UAVs) are aircraft that operate without a human pilot on board, often referred to as drones. These vehicles can be remotely controlled or fly autonomously through software-controlled flight plans, using a variety of sensors and navigational technologies. UAVs play a crucial role in various applications, including sensing and navigation in both aerial and aquatic environments, as well as in environmental monitoring and conservation efforts.
