  1. 1. Robust light source detection for AUV docking

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joar Edlund; [2023]
    Nyckelord :Autonomous Underwater Vehicle; Docking; Detection; Poseestimation; Visual Navigation; Autonoma Undervattensfordon; Dockning; Detektering; Positionsestimering; Visuell Navigation;

    Sammanfattning : For Autonomous Underwater Vehicles (AUVs) to be able to conduct longterm surveys, the ability to return to a docking station for maintenance and recharging is crucial. A dynamic docking system where a slowly moving submarine acts as the docking station provides increased hydrodynamic control and reduces the impact of environmental disturbances. LÄS MER

  3. 2. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Diogo Antunes; [2023]
    Nyckelord :Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Sammanfattning : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

  4. 3. AUV SLAM for Algae Farm Inspection : 3D Mosaicing using Sonar-Based SLAM

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Julian Valdez; [2023]
    Nyckelord :;

    Sammanfattning : The progression of seaweed farming and cultivation to an industrial scale relies on automating its processes. Utilization of Autonomous Underwater Vehicle (AUV) can enable this process through their capacity to automate crop and structural inspections. LÄS MER

  5. 4. RECOMMENDATIONS FOR A DEPENDABLE ROV SYSTEM FOR SWEDISH MARITIME RESEARCH

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :David Bernström; Erik Nyström; [2023]
    Nyckelord :;

    Sammanfattning : A Remotely Operated underwater Vehicle (ROV) faces many problems regarding dependability and most issues come during launch and recovery. The thesis looks at finding what dependability aspects shall be considered when developing a modular ROV to come up with recommendations for a system, together with a more reliable method of launching and recovering ROV’s.

  7. 5. Blind Acoustic Feedback Cancellation for an AUV

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Hampus Frick; [2023]
    Nyckelord :acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

    Sammanfattning : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. LÄS MER
