Unmanned vehicles, also known as unmanned aerial vehicles (UAVs) or drones, are machines that operate without a human pilot on board. They can be controlled remotely or fly autonomously using pre-programmed flight plans. These vehicles are used in various fields, including military operations, agriculture, and surveillance, due to their ability to access hard-to-reach areas and gather data efficiently. There are different types of unmanned vehicles, including land-based vehicles, underwater vehicles, and aerial vehicles. Each type is designed for specific tasks, such as exploring ocean depths or delivering packages. The technology behind unmanned vehicles continues to evolve, leading to increased capabilities and applications in everyday life.
