Underwater drones are basically remote-controlled submarines. Some are used for underwater photography or underwater filming but overall they have a wide range of use. These drones can enter deep waters and provide an immersive experience of the underground world to people with good video quality.

This is why along with marine biologists, people all around the world love underwater drones as it makes the experience so much more memorable. Luckily, there are sine underwater drones with a reasonable price that even you can buy. Here is everything that you need to know about underwater drones.

What is an underwater drone?

An underwater drone is also known as Unmanned Underwater Vehicles (UUV). As you know the underwater drone technology allows the drone to work underwater, without a human and without any hassle.

Drones are a type of robot and there are typically two types of underwater camera drones, which are listed below.

  • Remotely Operated Underwater Vehicles (ROUVs): These as the name suggests are remotely controlled by humans.
  • Autonomous Underwater Vehicles (AUVs): These are more advanced and can operate without any human input.

How do they work?

If you want aquatic drones, you should know how it works as well. This underwater robot is a very peculiar object and it would be a shame if you didn’t know a little about these drones work and give you a 3D video.

If you know how a submarine works well it is almost similar to how an underwater robot works as well. These, however, don’t have a crew and use their onboard sensors to function properly. More professional drones are used by having a direct connection between a ship and a drone. These don’t sink and have crush depths.

Either through a radio signal or another line, they have a connection to the control room from which they get operated by humans. The submarine drone all have different video capabilities, diving depth, battery life, and degrees of freedom. These factors depend on the price range as well as the range of accessories that it has.

What to look for

If you want a good underwater drone, here are some things that you should discuss beforehand. Almost all drones have video feed but very different functions as well. Therefore, before buying a drone keep these things in mind.

Lights and Camera

Usually, a drone has a camera that acts as your eyes and helps you see and navigate marine life and deep water.

Therefore, you should always look for a drone that has good light and camera quality as without these qualities the drone will be useless! Since you won’t be able to see or record anything properly anyway, so the average quality of the camera should be 720p video and should also have LED lights. Remember, the ocean is a dark place with no light so you will need to depend entirely on the light and camera ability of the drone to capture something interesting.

Tether Length

Next, you should look for tether length, but what is tether length anyways? Well, tether length minimizes the movement of the drone. Ideally, there should be a minimum diameter tether.

There are many types of tether as this helps the drone move and still stay within the signal range so you can control it. It should have a neutrally buoyant tether which should not require additional leads. Depending on how far you want your drone to go, the tether cable should be adjusted. Make sure to keep this point in mind before buying a drone as well.

Video Quality

Of course, this is one of the most important parts of a drone that you decide to buy. The video feed is what you will keep with you forever.

The point of a drone is to capture videos and images of the hard-to-reach parts of the ocean. The camera should be able to capture good quality videos without too much jerk so it is understandable. The video capability should be such that there is a total range of view as well instead of only one part of the ocean being visible. Picture, as well as video quality, should definitely be considered before buying a drone.

Battery Life

If the battery life is not long it can lead to the drone dying mid exploration and causing a lot of loss. So battery life is something you should not compromise on.

If you have an extra battery or swappable battery for your drone that is even better as you will be better prepared in case of emergency. Usually, there is about an hour or two of battery life for a good-quality drone. The battery life depends mainly on why you need a drone as for hobby this factor might not be that important but for professional use, you need a drone with optimum battery quality and life.

Distance Range

This again depends on what use you have for the drone and whether you will be using it for fun or for professional work.

Drones can either have a long-range or a short-range. A range is how far the submersible drone can travel underwater without facing problems like breaking down or losing the signal. Usually, a drone traveling up to 900 miles underwater is a good quality drone. The longest distance range of a drone is said to be up to 8000 feet! Of course, if for a hobby you don’t need such a long-range for your drone.
