What are underwater drones and how do they work?
Underwater drones, also known as underwater remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs), are robotic subs that operate underwater, usually for exploration, inspection, or research purposes. They are equipped with sensors, cameras, and other instruments that allow them to collect data, conduct surveys, and capture images or videos while navigating through the water.
The way they work varies depending on the design and purpose. Some underwater drones are autonomous, meaning they can operate independently without human intervention, while others are remotely controlled. They can be powered by batteries or fuel cells, and some may have advanced propulsion systems that allow them to move quickly and efficiently through the water. Some underwater drones are designed for deep-sea exploration, while others are better suited for shallower waters.
What are the different types of underwater drones?
There are several types of underwater drones, each designed for specific purposes and environments. For example, observation-class ROVs are used for general exploration and inspection, while inspection-class ROVs are designed for more detailed examinations of underwater structures or equipment. There are also intervention-class ROVs, which are equipped with manipulator arms or other tools for performing tasks such as maintenance or repair.
Additionally, there are specialized underwater drones for tasks such as marine research, search and rescue, and underwater construction. Some underwater drones are designed for specific environments, such as freshwater lakes, saltwater oceans, or brackish estuaries. The type of underwater drone used often depends on the specific requirements of the mission or project.
