By: Jeff Green and Kathryn Lear (authors/editors)

This Sep/Oct, Canada’s Memorial University of Newfoundland hosted the 2020 IEEE Oceanic Engineering Society (IEEE OES) Autonomous Underwater Vehicle (AUV) Symposium for the first time.

The biennial international conference was scheduled to be held in person in St. John’s – the historic capital city in the Province of Newfoundland and Labrador – but the ongoing COVID-19 pandemic forced organizers to develop the event as a virtual symposium. The event took place online from Sept. 30-Oct. 3.

The conference was organized by a committee consisting of representatives from Memorial University, its Marine Institute, the National Research Council of Canada and industry.

Thanks to a strong partnership with Memorial’s Conference and Event Services unit, the committee successfully delivered an innovative conference program.

Premier event

Dr. Neil Bose

Dr. Neil Bose, vice-president (research) at Memorial University, was the organizing committee chair. He noted IEEE OES is renowned around the world as an organizer of this premier event that brings together experts from industry, government and academia from all over the globe.

“Early this year, we decided to plan for a remote online conference. The key was how to make it work,” Dr. Bose noted.

“We planned presentations in a time-zone friendly asynchronous mode so it worked around the world. And we also planned networking, social events, exhibitor’s spaces, workshops, cultural events and more.”

Strong representation

The 2020 symposium attracted more than 100 registrants and 70 extended abstracts and full papers from 20 countries.

Paper topics included leading edge AUV developments in navigation; design; control; sensor design and data fusion; autonomy; mission planning; applications; multi-vehicle systems and open source robotics. There were also three submissions for a student poster competition.

The primary sponsor for the symposium was Kongsberg Maritime. Richard Mills, vice-president, marine robotics sales at Kongsberg Maritime, told Memorial University’s Gazette that as an industry leader, they felt it was important to support the research and academic community as they work to identify future challenges.

“We are keen to see new technologies and capabilities, but also how today’s systems are being used in challenging environments. AUV2020 is very much a learning opportunity for us and we look forward to renewing old friendships and making new ones.”

Opportunities for advancement

Dr. Ting Zou

Dr. Ting Zou, assistant professor, Department of Mechanical Engineering, Faculty of Engineering and Applied Science at Memorial, was the technical symposium chair.

Dr. Zou’s research focuses on the development of robotic technology for multiple areas, including underwater robots like AUVs, soft inspection robots to improve current inspection techniques for complex structures and intelligent robots based on AI methodology that can work independently without human intervention.

“The control of AUV and other underwater vehicles, like biologically inspired underwater robots, is one of my research focuses,” Dr. Zou told Memorial’s Gazette.

“I will take this opportunity to investigate the state-of-the-art in AUV control techniques to work in complex underwater environments.”

Gina Millar, research laboratory co-ordinator with Memorial’s Autonomous Ocean Systems Centre and symposium committee member, has worked in the water robotics industry for more than 15 years.

Ms. Millar says the majority of her time is spent working with the university’s International Submarine Engineering Explorer AUV, a deep-diving AUV rated for a 3,000 metre depth.

“The people I’m working with currently are conducting oil spill research. Some of their biggest challenges right now are their levels of autonomy with the vehicle,” Ms. Millar said in an interview with Memorial’s Gazette.

“Basically, we want the vehicle to make higher levels of thought processes and decisions. I think it is something that is important for the industry in general.”

“The AUV world is a small one, so we all have similar problems and it’s nice to get together with other people and do some brainstorming,” she added.

Special honours

During the 2020 symposium, several awards were presented to members of the international AUV community.

Rising Star recipients

There were two recipients of the Rising Star Award.

This award is to “Honor mid-career researchers and faculty that have made a demonstrable difference to our field and have the potential of continuing on the stellar track that they are following.”

The 2020 winners of the Rising Star Awards were: Dr Michael Jakuba, WHOI, USA and Prof Martin Ludvigsen, NTNU, Norway.

Dr. Jakuba completed his PhD degree in the MIT WHOI Joint Program in 2007 in the area of hydrothermal plume detection work that was later applied to detecting and characterizing the plume from the Deepwater Horizon Oil spill.

He went on to do a postdoc at the University of Sydney before returning to WHOI where he is currently a Senior Engineer.

He has been at the forefront of AUV design and deployments and been on a large number of oceanographic research cruises with various autonomous vehicles including the ABE and Sentry AUVs, the HROV Nereus, SeaBED-class AUVs, as well as Iver2 and REMUS AUVs.

Some of his notable achievements include the design and build of the Clio biogeochemical AUV Sampler and being the lead on the HROV Nereid Under-Ice.

Martin Ludvigsen is Professor and manager of the Applied Underwater Robotics Laboratory (AUR-Lab) at the Department of Marine Technology, NTNU where he teaches the course Underwater Engineering in Trondheim, Norway.

Over the course of his career he has worked on a variety of projects including on Marine Archaeology – notably on the Ormen Lange project, on imaging with ROVs, AUVs and Surface Vehicles and in pioneering work in the Arctic environment in Svalbard on diurnal phytoplankton migration in the polar night. He is also a co-founder and CTO of the highly successful Blueye Robotics.

IEEE OES AUV Lifetime Achievement Award

This award is presented to the person who has significant achievement and contribution on AUV technology in their lifetime.

The IEEE OES AUV Lifetime Achievement Award was presented to Prof. António Manuel Pascoal, a Professor at Instituto Superior Técnico (IST) in Lisbon, Portugal, and the head of the DSOR – Dynamical Systems and Ocean Robotics Laboratory at IST.
