Surface and Underwater drones : Features, Application, Advantages, Disadvantages

Drones, referred to as unmanned aerial vehicles (UAVs), are flying devices that can either be remotely controlled or fly autonomously and come in various shapes and sizes with features like propulsion systems for flight, navigation systems for control, task-specific payloads, and an operation control system. They have a wide range of applications, from aerial photography and videography, delivery, mapping and surveying, agriculture, environmental monitoring, rescue operations, law enforcement to military and defense. However, as technology improves and drones become more versatile, their use raises privacy and safety concerns leading to regulations in many countries to govern their usage.

What are Surface and Underwater Drones?

Surface drones, also known as ground drones, are unmanned aerial vehicles that operate on land or water surfaces. They are used for tasks such as inspection, surveying, mapping, delivery, search and rescue, and security operations and come in various shapes and sizes, with features like navigation systems, propulsion systems, and payloads for specific tasks.

On the other hand, underwater drones, also referred to as underwater remotely operated vehicles (ROVs) or underwater autonomous vehicles (UAVs), are underwater robots that can be controlled remotely or operate autonomously. Equipped with cameras, lights, and other sensors, they are used for tasks such as underwater exploration, inspection, surveying, and monitoring in various environments, including lakes, oceans, and rivers. They come in various shapes and sizes and are designed to manoeuver in the underwater environment and communicate with the operator on the surface.
