Submersible Robots Review - by Shalin Ghate

Submersible Robots Review by Shalin Ghate

As people become more involved with underwater photography/videography and underwater exploration, the interest has grown for personal underwater drones and remote operated vehicles (ROVs). Submersible drone prices range from anywhere between $499 and $10,000 and they possess all sorts of different features ranging from max depth, to camera quality, to weight. These are my reviews on which drones you should buy and why you should buy them.

If you're just getting into submersible drones as a novice, a popular option is the Chasing Innovation Dory. This drone is the cheapest drone on the market at $499 and it only weighs 2.5 kg. With a battery life of 1 hour and a max depth of 15m, this ROV moves at a max of 1.5 knots and has a camera that films video in 1080p.

          The next drone on the list is the perfect drone for fishermen. The Chasing F1 Fish Finder is a 2 kg ROV that provides you with information about the surrounding underwater terrain and the location of fish in the water. With a max depth of 28 meters, this can be used in the ocean and lakes. This drone also comes with a camera that films on 1080p and livestreams at 720p.

          The next few drones are similar in purpose and price range. They include​ the YouCan Robot BW Space Pro 4K, PowerVision PowerRay Explorer, PowerVision PowerRay Wizard, Chasing Innovation Gladius Mini, NAVATICS MITO, Geneinno Titan ROV, FIFISH, and the OPENROV Trident. 

The prices of these robots are from $848 - $1699 and I listed them from cheapest to most expensive. 

          The YouCan robot is a good photography robot but it doesn't have much maneuverability.  The PowerVision PowerRay Explorer and Wizard are both sleek looking, maneuverable ROVs that have   The YouCan robot is a good photography robot but it doesn't have much maneuverability.  

The PowerVision PowerRay Explorer and Wizard are both sleek looking, maneuverable ROVs that have a 4K video camera and 1080p streaming. The Wizard is more expensive because it comes with a fish finder and a VR headset. All of these ROVs have a 4K video camera and the max depth is around 100m for most of them. 

The rest of the drones listed above all function similarly to the PowerRay Explorer except they have varying weights, max depths, maneuverability features and more. For example, the Geneinno Titan ROV can go the deepest out of these robots with a max depth of 150m.

The Fifish has attachments like a grabber arm and a VR headset.

The Navatics Mito has a powerful LED attachment.

A utility-oriented robot for consideration  is the ThorRobotics 110ROV. At $1,878, this robot has most of the common features of the ROVs listed above and it comes with a grabber arm, but it only has a max depth of 30m.

If you like the ROVs above and you think you’re ready to upgrade maneuverability, features and build-quality, consider the NEMO ($2639) or CCROV ($3299).The Nemo has a battery life of 3 hours. 

The CCROV only lasts one hour, but it is a photography-oriented photography drone and considered among the best. It’s very small so you can get closer to fish without alarming them and you can maneuver in tight spaces.

The next two robots are designed for scuba divers: the Biki and the Ibubble. The Biki is a small robot shaped like a fish,  can be controlled remotely; and it’s designed to follow people. It can follow you on your dives or monitor kids in the pool and with a max depth of 65 feet, among many other functions. This drone cost only $999. The Ibubble costs much more  ($4,334) with the main advantage of  camera quality. It can only last for an hour which is half an hour less than the Biki, and it can only dive 60m. t It is just fully autonomous, but otherwise no controller.

The last two drones described here are the most advanced (and most expensive). The DTG3 starter ($5,749) is a robot that weighs 8.5 kg and has a max depth of 150m. With a battery life of 8 hours, this ROV can be under for a very long time. Plus, there are attachments like a claw and an LED to improve the functionality. 

Lastly, we have the Blueye ($9,878). The main distinction is the max depth of 300 meters  (almost 2 tenths of a mile!). It films in 1080p and has a lifespan of 2 hours. This robot also has great maneuverability and can manage currents up to 2 knots. It also has an app so you can choose to control the robot from the controller or using the touchscreen on your phone while watching the feed. The interface on mobile looks like it is straight out of a videogame.

This is my personal review of these drones based on the specs provided. Keep in mind, this is my ranking and other people may have other thoughts. After doing this research, I was surprised that there weren’t any other cheap ROVs. The other ones I found were all bath toys. As a growing industry, I look forward to seeing better drones released.
