    • Path Planning and Obstacle Avoidance for Marine Vessels Using the Deep Deterministic Policy Gradient Method 

      Aronsen, Mathias Graatrud (Master thesis, 2019)
      Med autonomi som et av hovedfokusene innen utviklingen av den maritime industrien er dokking-fasen et aspekt av et fullt autonomt fartøy som ennå ikke er utforsket fullt ut. På grunn av manøvreres kompleksitet er det ...

    • Planar Docking Algorithms for Underactuated Marine Vehicles 

      Loberg, Jon-Erik (Master thesis, 2010)
      The use of autonomously underwater vehicles (AUVs) has a great potential in scientific mission involving underwater exploration. However a major drawback with todays AUV missions is the launch and recovery process which ...

    • Precision control of fixed-wing UAV and robust navigation in GNSSdenied environments 

      Gryte, Kristoffer (Doctoral theses at NTNU;2020:198, Doctoral thesis, 2020)
      Unmanned aerial vehicles (UAVs) have been adopted to a wide range of applications, but fully autonomous flight is still utopian, especially for safety-critical applications. This thesis seeks to close this gap by mainly ...
