NTNU opens laboratory 365 meters below the surface

NTNU launches our deepest laboratory yet, almost 370 meters below the surface of the Trondheim fjord.

The lab was officially opened today by rector at NTNU, Gunnar Bovim, and Executive Vice President, TPD, at Equinor, Anders Opedal.

The lab's purpose is to test new underwater drones, and it will allow NTNU, Equinor and other partners to develop new radical solutions and innovations for underwater operations.

Before the opening, Asgeir Sørensen, director of NTNU AMOS, and Kjetil Skaugset from Equinor told the audience how the collaboration between NTNU and Equinor is changing how drones are used, not just under water, but also on the surface, and in the air.

Icing on Drones and Wind Turbines

Icing on Drones and Wind Turbines

Icing on Drones

A topic that has recently become a focus of research is icing on unmanned aerial vehicles, which in everyday language are known as drones. The wind power industry has a lot to gain from drone icing research. The physics of ice accretion on these is very similar, which means that tools validated for drone icing will also be applicable to wind turbine icing.

Enhancing education and Science cooperation

NTNU AMOS enters into a collaboration agreement with Arctic Research Centre, Institute for Bioscience - Aarhus University.

Enhancing education and Science cooperation

NTNU AMOS enters into a collaboration agreement with Arctic Research Centre, Institute for Bioscience - Aarhus University.

One of the most significant global issues over the past 20 years has been the vast change in the Arctic region. The world has again turned its attention to the Arctic, this time mainly because of climate change and its expected global impacts, the economic potential of the region, and the geopolitical implications of changes. Political, economic and social developments are already underway, including the flourishing of advanced democratic societies.

Undoubtedly the future of the Arctic will be radically different from the reality we know today. To meet these challenges, there is an urgent need to prepare the Arctic societies through improved knowledge and education of future generations. This is best done through partnerships among institutions in the Arctic.

By this collaborative agreement the NTNU AMOS and the Arctic Research Centre, Institute for Bioscience - Aarhus University have decided to further strengthen collaboration on education and research.

The collaboration agreement aims to create the basis for highly integrated and coordinated research and education collaboration focused around marine and arctic science and technology, logistical cooperation and strong international coordination of policy and governance related needs.

NTNU researchers has found a solution to landing fixed-wing drones on ships

Stormy seas with ship

There are several solutions for capturing fixed-wing drones from ships, but researchers at the Department of Engineering Cybernetics at NTNU and AMOS believe their method is better. It consists of two autonomous multikoptere with a line between them taking off from the ship, and receives position and planned path to fixed wing drone. By stretching the rope between them on the same course as the drone, and a little lower, established a blocking line.

Modern robotic technology presents new ways to map the oceans and gather data in a far more efficient and cost-effective way, then previously possible.

The autonomous underwater vehicles are able to cover a larger area than ships and stationary sensors. They are also able to make their own decisions on where to move in order to get the best possible samples.

These new methods are important if we are to gain a better understanding of the complex ecosystems of the oceans. More knowledge will hopefully help us make the best decisions on how to maintain and preserve the health of the oceans and their vital ecosystems.  

The research team conducted their experiments in the coastal waters near Runde Island, Norway. This area is affected by strong winds, ocean currents, and freshwater runoff from land. Fossum et al. used a light autonomous underwater vehicle (LAUV) to survey the edges of predefined volumes, and the resulting data allowed the robot to identify interior areas with high concentrations of subsurface chlorophyll a for additional, detailed sampling.

LAUV results were confirmed with data from remote sensing and shipboard samples. The combination of real-time data analysis and accurate, adaptive robotic sampling will help improve our understanding of marine food webs and their dynamic, heterogeneous environments.

MarineUAS - an EU-funded doctoral program to strengthen research training on Autonomous UAS for Marine and Coastal Monitoring

MarineUAS

MarineUAS is an EU-funded doctoral program to strategically strengthen research training on Autonomous Unmanned Aerial Systems for Marine and Coastal Monitoring. It is a comprehensive researcher training program across a range of partners in several countries designed to have high impact on the training of individual researchers and their knowledge, skills and their future careers. MarineUAS has established a unique cooperative environment. It takes benefit of the partners' extensive and complementary knowledge, field operational experience, and experimental facilities.

Marine UAS will build a solid foundation for long-term European excellence and innovation in this field by sharing research infrastructures for field testing and disseminating the research and training outcomes and best practice of MarineUAS into the doctoral schools of the partners, as well as by fostering long-term partnerships and collaboration.

Professor João Tasso de Figueiredo Borges de Sousa, Porto University & NTNU

Recent and exciting developments in multi-vehicle systems for maritime operations are presented along with projections of future research challenges lying at the intersection of control and computation. First, a novel approach to find, track and sample dynamic features of the ocean with a multi-vehicle system is briefly described as background for assessing potential future ocean operations. Second, we show that this is a system in which physical and computational entities evolve, interact and communicate within an environment that can also be modified by the actions of those entities. Third, we revisit Y. C. Ho’s generalized control framework – in which there is more than one criterion and more than one intelligent controller, each of which having access to different information – to suggest that we may have been missing something in coordination and control since 1970. Fourth, we review the pioneering work on systems with evolving structure of the late Turing award-winner Robin Milner; the focus is on computational processes, reaction rules, and mobile connectivity and mobile locality, all intrinsic to networked multi-vehicle systems, but missing in most of the control literature. Finally, we discuss how the control and computation challenges arising in multi-vehicle systems can be addressed in the framework of coupled physical and computational dynamics and show how these challenges can be formulated as problems of optimization, invariance, and attainability in extended state-control spaces.
