Last week Aquabotix traveled to London, UK to exhibit at the Oceanology International 2018 Exhibition and Conference, March 13-15, 2018. Oceanology International brings together marine professionals and businesses to discuss topics and technology to measure, develop, protect and operate across the world’s oceans.
Aquabotix displayed our technology-leading hardware and software, including the Endura™ ROV, Integra™ Hybrid AUV, and live remote-control software. Visitors at the Aquabotix stand in London, UK were able to take live control of an Endura ROV located in Fall River, MA to remotely pilot the vehicle from a web browser.
Water Linked, an underwater GPS company, had an Endura™ ROV on display which featured a Water Linked GPS, capable of tracking vehicle position using a series of transponders located around the sides of the water tank. Water Linked can be used for accurate vehicle position tracking inside potable water tanks, and alongside ship hulls. Water Linked demonstrated the Endura running “position hold” to remain within the center of the tank.
During the show, Aquabotix also announced the sale of a Hybrid AUV to KIGAM (Korea Institute of Geosicience and Mineral Resources). KIGAM plans to use the Hybrid for ongoing geoscience and energy research in Korean waters. Jung Kyun Shin, KIGAN senior researcher said: “The lightweight feel and ease-of-use of Aquabotix’s Hybrid vehicle will be instrumental in helping us fulfill our research and tasks over multiple missions.”
Ted Curley, Chief Development Officer at Aquabotix noted: “We had a great week at Oceanology International, being able to display our Integra™ Hybrid AUV and Endura™ ROV. Participants loved the live viewing and live remote control to our ROV in Fall River, MA – what a great way to showcase it all!”

Multibeam sonar systems work by emitting a specific frequency of sound wave in a fan shape which bounces off the sea floor and returns to the receiver. The result is an image which shows detailed depth data and refreshes several times per second. High frequency multibeam sonar systems allow for higher resolution mapping at closer ranges, revealing enough detail to accurately identify underwater targets even in low visibility water conditions. Each multibeam sonar system is rated for a certain field of view (degrees of viewable image) and range (meter depth to sea floor before the sound bounces back).
As multibeam sonar systems have progressed, they have become smaller, lighter, more cost-effective, and easier to use. These advances have allowed multibeam sonar to be deployed to a wide range of vessels and underwater vehicles. Some of the smallest multibeam sonar systems, such as the Oculus M series multibeam sonar from Blueprint Subsea, are designed for use with inspection-class ROVs. When mounted to ROVs and AUVs, multibeam sonar is most often used to locate underwater objects. Interpreting a multibeam sonar image takes some experience and skill but it becomes much easier when you know what you’re looking for; Blueprint gives an example of what a Tire looks like, which is easily identified from the sea floor. When used for Search and Recovery, sonar is sometimes the only way to locate a lost person or object. When used for offshore oil and gas, sonar is often used to survey the sea floor in a lawnmower pattern, or for following underwater cables/infrastructure.
Whatever the application, multibeam sonar is an important option for all underwater vehicles which need to efficiently cover large search areas and become almost mandatory when used in low visibility or turbid environments where a live video feed is less effective.

UUV Aquabotix Ltd (ASX:UUV) (“Aquabotix" or the “Company”) today introduced Live Remote Control, which allows users to pilot Aquabotix’s underwater vehicles and cameras from any web browser-enabled device, remotely, from anywhere in the world. This class-leading technology has applications for any business, research centre, security force of defence unit with a multi-site presence in the underwater world.
Live Remote Control enables users to operate Aquabotix’s Endura ROV (remotely operated vehicle), Hybrid AUV/ROV (autonomous/remotely operated vehicle) and AquaLens Connect (networked underwater camera system) during underwater activities from any location globally, using browser-based devices such as computers, phones and iPads, over the Internet, without the operator being physically present on-site.
Below is an artist’s rendering of Live Remote Control’s applicability to the aquaculture sector. For example, the operator could be sitting in the head-office in Norway, and controlling an Endura in a fish net at an aquaculture farm off the coast of Chile, thousands of miles away.
Importantly, Live Remote Control also enables multiple operators (in multiple global locations, if needed) to operate the same unmanned underwater vehicle.
Live Remote Control is designed to expand the virtual presence of Aquabotix’s product users, allowing them to better monitor what’s happening at all times, while sharing data across multiple sites. The web-driven innovation also reduces the need for increased or expensive on-site manpower for underwater operations.
This method of operation is conceptually somewhat similar to how the world’s technologically most advanced militaries have, for years, operated battlefield aerial drones from safe locations outside of the theatre of war.
“With Live Remote Control, any browser-based modern device can now interact with our system,” said Durval Tavares, CEO of Aquabotix. “Having our customers operate unmanned systems underwater in a live, immediate fashion, from anywhere in the world, is a game-changer for the underwater robotics industry. Advances in underwater unmanned systems typically lag those in the aerial domain by several years. Aquabotix is proud that the smart computing power of its vehicles enables the company to achieve innovations like these, which are at the forefront of advances in the industry.”
“Driving an underwater vehicle through a web browser previously seemed impossible,” said Ted Curley, Chief Development Officer of Aquabotix. “Live Remote Control now changes the timeline for how underwater processes can be accomplished both on land and under the sea.”

When most people think of mining they imagine terrestrial mining operations consisting of earth moving machines designed to dig down to bedrock to extract gold, coal, or diamonds. Offshore mining, also called Deep Sea Mining, is a rather new method of extracting precious materials from the ocean floor. Raw materials present on the sea floor include gold, silver, copper, cobalt, zinc and diamonds and are often found in concentrations much higher than those found on land. Precious metals and stones are often found near alluvial deposits, volcanic belts and underwater mountains. Until recently, the technology needed to efficiently mine underwater was not available. Mining dredges have been around since the early 1900s, however, the Remotely Operated Vehicles (ROVs) necessary to explore the most valuable underwater claims are a relatively new innovation.
The single largest factor which has held back underwater mining has been the cost of operating an offshore mine. Commissioning a dredge ship, crew, fuel and rolling the dice on mining untested ocean floor is too risky to invest in. But the economics of offshore mining are changing. Rare earth minerals are being consumed at a rapid rate to manufacture devices such as cell phones and solar panels. British scientists recently discovered Tellurium deposits off the coast of the Canary Islands which have concentrations 50,000 times higher than land deposits, according to the BBC. Tellurium is used in the construction of solar panels and semiconductors, and discoveries like this are critical to meet the growing demands in these sectors.

The efficiency of offshore mining exploration is improving as well. Prospectors of the 21st century don’t carry a pick-axe or a gold pan, they carry remotely operated vehicles to explore, probe and test sample materials brought back from the depths of the ocean. The more samples that can be collected, the more confident a prospector can be of the density of target minerals. This means that fleets of remotely operated vehicles are needed to pinpoint the richest areas of ocean crust before any mining can occur. The use of on-board cameras, drills, and sample collectors are critical tools to deploy while prospecting. Once an offshore mine is established, inspection class ROVs become an important way to monitor the condition of mining equipment from the safety of the surface.
Offshore mining is still in its infancy, and it’s a highly controversial subject. The ocean belongs to us all, and marine environments can be complex and delicate. We are now presented with a social dilemma: continue to mine on land and strip large areas down to bedrock, or carefully pinpoint the most concentrated marine deposits and do everything possible to minimize environmental impact. Before any mining can occur, environmentally-conscious contracts are signed between miners and the nations or states which own off-shore resource rights.
Offshore mining is the last frontier on Earth for the discovery of rare earth minerals, many of which will be necessary for our transition on to more renewable forms of energy. The more we know about the ocean floor the better prepared we will be to make decisions around the responsible harvest of these raw materials. ROVs are providing the data necessary to open our world to the possibilities of offshore mining.
