How do you create a system the place drones survey underwater, with out really sending a drone underwater? There are definitely waterproof drones that perform extra like submarines, typically resembling manta rays that glide underwater by the controller of an ordinary RC transmitter.
However the group on the College of Florida, in partnership with a personal software program firm referred to as Aurigo, has constructed an answer the place drones survey underwater whereas nonetheless functioning as a stereotypical drone, flying by the air.
It’s what some may take into account a revolutionary system for underwater surveying, mapping, and inspection, as it would unlock real-world functions that aren’t in any other case presently commercially out there. They’re calling it “Bathydrone.”
How does Bathydrone work to survey underwater?
With the Bathydrone system, a drone drags a small vessel on the water’s floor. That vessel is provided with a commercially-available, off-the-shelf sonar unit mounted on its backside.
And it’s that sonar unit that has down-scan, side-scan, and chirp capabilities, making it doable to log information onboard the console, which is positioned contained in the hull. After the drone’s flight and the sonar unit is retrieved, information can then be uploaded post-mission from the console.
Briefly, the drone does the driving, and a totally totally different piece of know-how does the data-gathering, which is a comparatively distinctive mannequin amidst the myriad of drone functions.
And lots of specialists imagine this methodology the place drones survey underwater by dragging sonar models within the water is a big enchancment of the present course of for a lot of causes, together with being doubtlessly cheaper, safer and extra eco-friendly.
“The present course of to collect information for brand new underwater building or the inspection of current belongings akin to bridges, docks, and levees consists of guide surveying from divers or survey sensors mounted to a ship,” in accordance with an announcement from Aurigo. “With the brand new, safer, and extra environment friendly Bathydrone system, a drone drags a small vessel on the water’s floor, eliminating the necessity for guide surveying.”
Listed below are some options and advantages of Bathydrone in a nutshell:
- Absolutely battery-operated: Which means it requires no gas and emits much less noise, which is healthier for the setting.
- Light-weight and simply transportable: It doesn’t even require a dock or boat ramp to get within the water, so it might be deployed in additional locations.
- Versatile to setting: It’s capable of be deployed in all kinds of water programs, together with shallow water and rivers with sturdy currents.
- Highly effective: It’s capable of survey a big space on a single cost.

What are the use circumstances of drones that survey underwater?
Any situation the place you’d should survey and map underwater counts as a use case. Which may embody mapping and inspection important infrastructure, like docks, levees and bridges. Within the U.S., there are greater than 617,000 bridges, and greater than half are underwater. And since the typical age of a bridge within the U.S. is about 44 years outdated, common upkeep inspections are essential.
However conventional strategies are difficult. By some estimates, the mixed value of the collective backlog for inspections and upkeep is pegged at $125 billion nationwide. By slicing again on the necessity for guide inspection utilizing divers (which can also be doubtlessly dangerous and error inclined), the Bathydrone answer might be the long run.
Comparable merchandise have tried to attain what Bathydrone guarantees, albeit in a special method. For instance, Chinese language drone producer PowerVision constructed an underwater drone referred to as PowerRay that means that you can livestream what the drone sees instantly by your smartphone or pill and may go as deep as about 100 ft underwater (and may detect objects as much as about 230 ft under the floor). Although, with out sonar (amongst different excessive tech) that extra consumer-oriented drone isn’t almost as superior as one thing like what the Bathydrone guarantees to be.
Different comparable opponents to the PowerRay embody the Gladius Mini, which once more, can see underwater however is much from as highly effective because the Bathydrone. The Gladius Mini goes for about $1,000 (the common value is $1,199 however it’s typically on sale).
The goal Bathydrone prospects embody state departments of transportation, ports and marine authorities, federal, protection, and native authorities companies who have to construct and keep belongings that cross water.
How did Bathydrone come about?
Bathydrone is constructed by two entities working collectively. On the non-public facet, there’s Aurigo Software program, which is headquartered in Austin, Texas, but additionally has workplaces in Canada and India. Aurigo builds cloud-based software program based mostly on proprietary synthetic intelligence and machine studying know-how that’s designed for capital infrastructure and personal homeowners to assist construct with high quality, and keep belongings. It claims to have greater than 300 prospects, which symbolize a mixed 40,000 initiatives throughout North America with greater than $300 billion of capital packages below administration.
Aurigo is already pretty well-regarded for its Aurigo’s Masterworks Cloud Platform, which helps correctly retailer and categorize mission information and route any inspections or different outcomes for approval or additional motion. That tech will, unsurprisingly, be built-in into Bathydrone.
And on the general public facet, there’s the College of Florida, a serious, public, complete, land-grant, analysis college (and the oldest within the state). The college’s Division of Mechanical and Aerospace Engineering is spearheading the mission.
Aurigo’s CEO, Balaji Sreenivasan, is definitely a graduate of the college, having accomplished his masters at UF’s Division of Mechanical and Aerospace Engineering in 1999. Throw in the truth that Florida is an ideal geographic match given its proximity to many our bodies of water, and the present drone analysis executed by Dr. Peter Ifju (who’s engaged on the Bathydrone mission), and the partnership between Aurigo and the College of Florida is a fairly pure match.
And so far as the identify itself, and the way the moniker ‘Bathydrone’ happened? Bathydrone is a mixture of two phrases: Drone and Bathymetry, which is the science of underwater surveying and mapping.
What’s subsequent for Bathydrone?
If you need one now, good luck. The general public can’t get their palms on one but. Whereas the product itself is already fully-deployable in its present state — which suggests it’s able to being programmed to run robotically, accumulate information, and render the findings in actual time for the engineers working the mission — it’s not even in what’s thought-about beta testing but.
However over the following yr to 18 months, Aurigo will work carefully with the College of Florida’s Division of Mechanical and Aerospace Engineering’s workers and college students in anticipation of bringing this method the place drones survey underwater to the industrial infrastructure market.
The following step is to check the system below extra real-world situations as doable, all of the whereas making effective changes to the vessel and drone parts. For now, all testing is being carried out by Aurigo and their analysis companions at College of Florida amenities in Gainesville and the encircling space.
And by early 2024, Bathydrone ought to be in official beta testing mode. As soon as that occurs, Aurigo prospects (which is ready to incorporate the Division of Transportation and different federal companies and port authorities who presently use Aurigo Masterworks to plan and handle their initiatives) will take part in subject testing on websites they oversee.
Whereas the corporate wouldn’t say how a lot it’ll probably value as soon as the product is lastly to market — and maybe it’s even too quickly for them to say what it’s value — a spokesperson for the Bathydrone product mentioned that as of now, companies spend between $1,500 – $5,000 to examine bridges right now, and wherever from $25,000 – $45,000 for extra advanced belongings which can be over water.
“Whereas the price of the Bathydrone can be considerably decrease for a way more environment friendly and correct inspection and survey course of, that is additionally about growing security on the job web site and never placing human lives in danger,” a spokesperson mentioned.
