What is an underwater drone and how does it work?
An underwater drone, also known as a remotely operated vehicle (ROV), is an unmanned underwater device that is operated remotely by a person on the surface. It is equipped with sensors, cameras, and other instruments that allow it to explore and survey the underwater environment. The drone is connected to the surface by a tether, which provides power and communication.
The drone is controlled by a pilot who uses a remote control or a computer to command the device to move or perform specific tasks. The drone’s movements are typically smooth and deliberate, allowing it to navigate through tight spaces and rough terrain. The sensors and cameras on the drone provide real-time video and data feedback to the pilot, allowing them to make adjustments and decisions based on the information being gathered.
