How do you create a system the place drones survey underwater, with out really sending a drone underwater? There are actually waterproof drones that operate extra like submarines, typically resembling manta rays that glide underwater by way of the controller of a regular RC transmitter.
However the staff on the College of Florida, in partnership with a non-public 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 way of the air.
It’s what some would possibly take into account a revolutionary system for underwater surveying, mapping, and inspection, as it’d unlock real-world purposes that aren’t in any other case at present 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 situated 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.
In brief, the drone does the driving, and a totally completely different piece of know-how does the data-gathering, which is a comparatively distinctive mannequin amidst the myriad of drone purposes.
And lots of consultants imagine this methodology the place drones survey underwater by dragging sonar items within the water is a large enchancment of the present course of for a lot of causes, together with being probably cheaper, safer and extra eco-friendly.
“The present course of to collect information for brand new underwater building or the inspection of current belongings comparable to bridges, docks, and levees consists of guide surveying from divers or survey sensors mounted to a ship,” in keeping with a press release 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 here are some options and advantages of Bathydrone in a nutshell:
- Totally battery-operated: Meaning it requires no gasoline and emits much less noise, which is healthier for the surroundings.
- 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 surroundings: It’s in a position to be deployed in all kinds of water programs, together with shallow water and rivers with sturdy currents.
- Highly effective: It’s in a position to survey a big space on a single cost.

What are the use instances of drones that survey underwater?
Any situation the place you’d should survey and map underwater counts as a use case. That may embrace mapping and inspection crucial 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 common 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 be probably dangerous and error susceptible), the Bathydrone answer might be the longer term.
Related 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 permits you to livestream what the drone sees instantly by way of your smartphone or pill and may go as deep as about 100 toes underwater (and may detect objects as much as about 230 toes under the floor). Although, with out sonar (amongst different excessive tech) that extra consumer-oriented drone shouldn’t be practically as superior as one thing like what the Bathydrone guarantees to be.
Different related opponents to the PowerRay embrace the Gladius Mini, which once more, can see underwater however is way from as highly effective because the Bathydrone. The Gladius Mini goes for about $1,000 (the common worth is $1,199 however it’s typically on sale).
The goal Bathydrone prospects embrace state departments of transportation, ports and marine authorities, federal, protection, and native authorities businesses who must construct and preserve belongings that cross water.
How did Bathydrone come about?
Bathydrone is constructed by two entities working collectively. On the personal aspect, there’s Aurigo Software program, which is headquartered in Austin, Texas, but in addition has workplaces in Canada and India. Aurigo builds cloud-based software program primarily based 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 preserve belongings. It claims to have greater than 300 prospects, which signify a mixed 40,000 initiatives throughout North America with greater than $300 billion of capital applications underneath 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 aspect, 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 performed by Dr. Peter Ifju (who’s engaged on the Bathydrone mission), and the partnership between Aurigo and the College of Florida is a reasonably pure match.
And so far as the title itself, and the way the moniker ‘Bathydrone’ took place? Bathydrone is a mix of two phrases: Drone and Bathymetry, which is the science of underwater surveying and mapping.
What’s subsequent for Bathydrone?
In order for you 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 mechanically, gather information, and render the findings in actual time for the engineers operating the mission — it’s not even in what’s thought of 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 business infrastructure market.
The subsequent step is to check the system underneath extra real-world situations as doable, all of the whereas making tremendous changes to the vessel and drone elements. For now, all testing is being performed by Aurigo and their analysis companions at College of Florida services in Gainesville and the encircling space.
And by early 2024, Bathydrone needs to be in official beta testing mode. As soon as that occurs, Aurigo prospects (which is about to incorporate the Division of Transportation and different federal businesses and port authorities who at present use Aurigo Masterworks to plan and handle their initiatives) will take part in discipline 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 price — a spokesperson for the Bathydrone product stated that as of now, businesses spend between $1,500 – $5,000 to examine bridges in the present day, and wherever from $25,000 – $45,000 for extra complicated belongings which are over water.
“Whereas the price of the Bathydrone might 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 website and never placing human lives in danger,” a spokesperson stated.
