UFRJ Nautilus: A Brazilian AUV Project

The UFRJ Nautilus AUV is an academic project designed to develop autonomous underwater vehicle (AUV) technology in Brazil and participate in the annual Robosub competition. According to project founder, Lucas Armand, a Naval and Ocean Engineering graduate from the Federal University of Rio de Janeiro (UFRJ), the emergence of Nautilus has a lot to do with personal history: “I was having a difficult time in college, because I no longer identified myself with the course. The UFRJ Naval Engineering degree tends to be quite traditional – sometimes even old-fashioned – and I’ve

Subsea Defense: Extending Unmanned Capabilities

Unmanned Warrior in 2016, which showed navies that, when used in cooperation, maritime autonomous platforms could create a modular and extendable defense system.Leaning on Commercial SystemsOperation Unmanned Warrior also showed the defense sector that it could learn from commercial and scientific AUV technology, says Shepherd, where range, loitering time, swarm operations, autonomous behavior capability and connectivity via surface vessels and satellite are being developed and extended.Chris Lade, Defense Sales Manager at Saab, agrees: “More and more of the commercial world is spending time under

underwater vehicles (AUVs) operate.The firm, founded in 2001, near Vancouver, Canada, initially focused on hard rock mining robotics, but then moved into the ocean space, developing seafloor mining robotics systems and then seafloor drilling systems. One of its latest projects, however, is a hovering AUV technology and fuel cells for long-range, long-endurance AUVs.It’s a natural progression for Cellula, whose founder Eric Jackson’s background is in AUV technologies. For more than 20 years, Jackson worked at International Subsea Engineering, also near Vancouver, working on submarine control

Kraken Bags AquaPix Sonar Contract

from this customer. The reason this customer has once again selected AquaPix is because it is the industry leading sonar system, which provides military grade technology enabling superior 3D seabed imaging, faster data processing and a lower cost than competing sonars. With the increasing focus on AUV technology, Kraken’s line of underwater sensors are well-positioned in this high-priority, high-potential growth area. We thank our customer for their ongoing confidence in our technology and products.”AquaPix is designed for operation on Autonomous Underwater Vehicles (AUVs), manned and unmanned

Hydroid's Most Compact AUV Ever Produced

and engineers at Hydroid set themselves the task of designing one of the most compact autonomous underwater vehicles (AUVs) ever produced, they collaborated with Nortek to provide high-quality navigational equipment capable of fitting such a small form factor.   Hydroid has built on REMUS AUV technology – first developed at the Woods Hole Oceanographic Institution in Massachusetts – to become a leading manufacturer of trusted, field-proven lightweight AUVs for underwater search and survey. Acquired by Norwegian technology firm Kongsberg Maritime in 2008, the company manufactures

PicSea: A New Concept for Ocean Autonomy

PicSea, Durrant aims to make underwater data more accessible to those within the scientific community that lack access to large budgets or advanced technological resources. Durrant said, “There’s a very limited subset of people who not only want ocean data but can afford access to AUV technology. For example, I know a group of biologists who want to carry out lots of environmental surveys using AUVs, but their budgets just don’t allow for it. This sort of thing is widespread across the scientific community, and it’s something I am hoping to change with the PicSea concept

Kraken Wins Repeat AquaPix Contract

pleased with this repeat contract award from a long-standing customer. AquaPix is an industry leading sonar system providing military grade technology that enables superior 3D seabed imaging, faster data processing and a lower cost than competing sonars. With the increasing international focus on AUV technology, Kraken is well-positioned in this high-priority, high-potential growth area.”   Conventional side scan systems are limited in that they only provide high resolution imagery at short ranges. AquaPix produces ultra high-resolution seabed imagery at long ranges. The additional information

Modus unveils Saab Sabretooth for cost effective survey, inspection

. The company is also developing a fully-managed service to support holistic data harvesting and management, in combination with advanced mission planning and execution. Modus and Saab have entered into an agreement that focuses on research and development to generate a road map for hybrid AUV technology. “Our solution is a gamechanging development for the subsea industry,” says Managing Director of Modus Seabed Intervention, Jake Tompkins. “This innovation addresses the challenges facing this sector and the current economic environment,” Jake continues. “We are

targets on the seafloor the size of your thumb at ranges of 315 meters to either side. So, we were hoping that this formidable technology would blaze large swaths of this uncharted stretch of the Victoria Strait where we hoped one of the wrecks lay hidden.”   Harris and his team applied AUV technology to the search for Franklin’s ships. While the team had somewhat mixed results, this reflects not on the technology itself but on the challenging environment in the North. As such, the discovery of the shipwrecks came about through the marriage of marine survey technologies and painstaking

the specific task that they were designed to complete. Since then, technology has progressed allowing them to become dynamic platforms for a variety of imaging, chemical, biological, acoustic and oceanic sensors that can be adapted to meet the needs of a specific project.   During the 1990s, AUV technology entered an intense research and development phase which was largely funded by national defense agencies, with commercial vehicles not widely available until around 2000.    Today, with advances in technology, gliders operate with little or no need for powered systems and are typically
