What is an underwater drone?

In this article we will understand what an underwater drone, also known by the acronym ROVs, is and its importance in the exploration of the aquatic world. Underwater drones are designed to explore aquatic environments without requiring a crew. We will discover how these underwater robots become great explorers of the oceans, capturing images and collecting data that reveal the secrets hidden beneath the surface. By diving into this post, you will discover the fascinating universe of underwater drones. We will explore together how they work, what essential parts make them up and how they are controlled from the surface.

Definition of underwater drone

Underwater drones, also known as Remotely Operated Underwater Vehicles (ROVs), are devices designed to explore the underwater world without the need for a crew on board. They operate thanks to a set of advanced systems that allow them to submerge in the water and navigate autonomously or under the remote control of an operator from the surface.

Parts of an ROV

An underwater drone consists of several essential components. Its exterior has a waterproof casing to protect the internal systems from moisture. To move, they use motors and propellers, allowing them to move in any direction. In addition, they are equipped with high-resolution cameras and sensors capable of capturing images and data of the underwater environment.

How are they controlled?

Communication is fundamental to the operation of underwater drones. To control it from the surface, umbilical cables or wireless signals (light or sound) are used to send commands and receive information from the drone. This facilitates control over navigation, image capture and data collection. Its ability to operate autonomously or under remote control allows access to hard-to-reach places, enabling the capture of unique images and the collection of valuable data. Thanks to their efficient technology and communication systems, underwater drones stand out as essential tools for multitude of applications. As technology evolves, the contribution of underwater drones becomes ever more fundamental to the understanding and preservation of our vast and mysterious underwater ecosystem.
