    • A hybrid approach to underwater docking of AUVs with cross-current 

      Henriksen, Vegard F; Brekke, Edmund Førland; Pettersen, Kristin Ytterstad; Sans-Muntadas, Albert (Journal article, 2016)
      This paper proposes a docking maneuver for an underactuated autonomous underwater vehicle (AUV) to dock into a funnel shaped docking station. The novelty of the proposed approach is enabling an underactuated AUV that is ...

    • Adaptive motion planning and path following for permanent resident biofouling prevention robot operating in fish farms 

      Føre, Martin; Fjæra, Sverre; Ohrem, Sveinung Johan; Kelasidi, Eleni; Bloecher, Nina; Amundsen, Herman Biørn (Journal article, 2022)
      This paper presents a study where the potential of achieving autonomous net cleaning operations in commercial net pens is demonstrated through numerical simulations. Specifically, we investigated solutions for coping with ...

    • Autonomous Flow-Through RGB and Hyperspectral Imaging for Unmanned Surface Vehicles 

      Haugum, Matias; Fragoso, Glaucia; Henriksen, Marie Bøe; Zolich, Artur; Johansen, Tor Arne (Journal article, 2023)
      The process of collecting samples for traditional microscopic analyses can be costly and time-consuming. We present the design of an autonomous flow-through imaging (AFTI) system tailored for small unmanned surface vehicles ...

    • Autonomous Optical Survey Based on Unsupervised Segmentation of Acoustic Backscatter 

      Sture, Øystein; Fossum, Trygve Olav; Ludvigsen, Martin; Syre Wiig, Martin (Journal article, 2018)
      The application of acoustics to study the seabed have for decades provided industry and science with valuable information, and is still excels in terms of spatial coverage and detail. An acoustic response from the seabed ...

    • Distributed motion sensing on ships 

      Heyn, Hans-Martin; Udjus, Guttorm; Skjetne, Roger (Journal article; Peer reviewed, 2017)
      A current trend is autonomous transport of goods and people in the air, at land, and at sea. For safe and reliable operations, autonomous systems require sensors that replace, or even exceed, the senses of a human operator. ...

    • Hierarchical Compliance-Control-Based Docking of a UVMS 

      Nysæther, Torje; Pettersen, Kristin Ytterstad; Gravdahl, Jan Tommy (Journal article, 2023)
      The viability of underwater vehicle-manipulator systems (UVMS) in underwater intervention missions is heavily reliant on safety. For safe operations, a UVMS should specifically be able to both avoid dangers and interact ...

    • Simulating Hyperspectral Datacubes for Ocean Color: A Foundation for Phytoplankton Recognition in Spectral Signatures 

      oudijk, AE; Johansen, Tor Arne; Johnsen, Geir; Alver, Morten Omholt (Journal article, 2023)

    • Transfer Learning in Underwater Operations 

      Skaldebø, Martin Breivik; Sans-Muntadas, Albert; Schjølberg, Ingrid (Journal article, 2019)
      This paper investigates a method for reducing the reality gap that occurs when applying simulated data in training for vision-based operations in a subsea environment. The distinction in knowledge in the simulated and real ...

    • Unmanned vehicle and hyperspectral imager for a more rapid microplastics sampling and analysis. 

      Deschenes, C; Zolich, Artur; Wagner, Martin; Johnsen, Geir; Johansen, Tor Arne; Faltynkova, Andrea (Journal article, 2023)
      In this paper, we present a proof-of-concept study aiming to improve the sampling and analysis of microplastics (MPs) by implementing a novel methodology combining an autonomous surface vehicle and a near-infrared hyperspectral ...
