What is an underwater drone?

Underwater drones, also called unmanned underwater vehicles (UUV) are vehicles that are able to operate underwater without a human occupant. These vehicles are available in two categories: remotely operated underwater vehicles (ROVs) and autonomous underwater vehicles (AUV).

ROVs are controlled by a remote human operator. They are submersible and capable of operating underwater. They are controlled via tether by a single person or crew.

This type of drone operates independently of direct human input. They are often preprogrammed to travel autonomously to a specified location via GPS and perform a designated task like sensor readings, land survey, data collection and more.

When to use underwater drones?

Underwater drones offer a number of benefits because they can do things that no other tools can perform. If you are wondering whether you should get this type of quad or not, then this section should help you decide.

Here are some reasons underwater drones are very helpful.

Safe exploration
Underwater drones offer you a safe alternative to explore the dangerous areas for divers. You can easily deploy it in underwater locations to gather remains and collect data.

Fits into confined areas
Underwater drones come in different sizes, there are small and big ones. Those small in sizes are capable of maneuvering and inspecting small and hard to reach areas underwater. This proves to be helpful when collecting data in areas unattainable by divers.

Quick deployment
In emergency situations when time is limited, underwater drones can help you get the job done because they can be deployed immediately. In fact, some can be deployed in as little as 30 seconds.

Longer dive time
Divers can remain underwater for up to 30 minutes to an hour. The majority of the jobs under the sea require several hours to finish which is quite daunting for divers and not to mention, more costly because divers have to keep on returning to the water until the job is done. However, underwater drones have a long battery life, some can even last up to 8 hours, making it capable of finishing a job in a single plunge.

Underwater Drone Applications

Underwater drones prove to be very helpful in various industries. Here are the different applications where underwater drones are beneficial.

Aquaculture. Fish farmers use an underwater drone for net inspections, lighting, feeding, stock monitoring and troubleshooting. With this tool, they can ensure a healthy fish crop and efficient harvest.

Commercial and salvage diving. Underwater drones are used to assess the underwater environment. This can help mitigate risks, which makes the job easier and safer for the divers.

Municipal infrastructure. Routine inspections are critical for long-term care of infrastructure. Underwater infrastructure like dams, bridges and reservoir inspections used to be a difficult job to do and it is often risky. Good thing underwater drones get the job done without the risks and at a lesser cost.

Cinematography/Photography. Taking photos and recording videos underwater whether for photography or filmmaking has never been easier with the use of underwater drones.


Underwater drones are very helpful if you want to explore the world under the sea whether its for entertainment, business or research purposes, search and rescue operation and more. These aircraft are designed to be submerged making them the most efficient tool when you are working about anything underwater.

For those who have used underwater drones in the past, what’s the best one for you? Feel free to share your experiences and ideas with us! We would love to hear from you!
