• Autonomous ROV inspections of aquaculture net pens using DVL 

      Amundsen, Herman Biørn; Caharija, Walter; Pettersen, Kristin Ytterstad (Peer reviewed; Journal article, 2021)
      This article presents a method for guiding a remotely operated vehicle (ROV) to autonomously traverse an aquaculture net pen. The method is based on measurements from a Doppler velocity log (DVL) and uses the measured ...
    • Framework for Autonomous Navigation for a Permanent Resident Aquaculture Net Grooming Robot 

      Skaldebø, Martin Breivik; Ohrem, Sveinung Johan; Kelasidi, Eleni; Amundsen, Herman Biørn; Bloecher, Nina (Journal article, 2023)
      This paper proposes methods to enable autonomous operation, specifically for localization and motion planning, of net grooming robots in aquaculture net pens and validates the proposed methods in both simulations and ...
    • Robust adaptive backstepping DP control of ROVs 

      Ohrem, Sveinung Johan; Amundsen, Herman Biørn; Caharija, Walter; Holden, Christian (Peer reviewed; Journal article, 2022)
      Dynamic positioning is an important control feature for an underwater remotely operated vehicle. This paper presents a nonlinear dynamic positioning controller suited for application to vehicles with model uncertainties, ...
    • ROV Navigation in a Fish Cage with Laser-Camera Triangulation 

      Bjerkeng, Magnus Christian; Kirkhus, Trine; Caharija, Walter; Thielemann, Jens T; Amundsen, Herman Biørn; Ohrem, Sveinung Johan; Grøtli, Esten Ingar (Peer reviewed; Journal article, 2021)
      Aquaculture net cage inspection and maintenance is a central issue in fish farming. Inspection using autonomous underwater vehicles is a promising solution. This paper proposes laser-camera triangulation for pose estimation ...
