  1. 1. Robust light source detection for AUV docking

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Diogo Antunes; [2023]
    Keywords : 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;

    Abstract : 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.

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Julian Valdez; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 4. Development of a real-time navigation and collisionavoidance system for an autonomous naval rover : A Contribution to the Environmental Initiative for Flexible andReal-time Water Monitoring of the CatFish team

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Esmee Tackx; [2023]
    Keywords : ;

    Abstract : This thesis explores the design and optimisation of a sensor system for real-time position determination of the Fish component in the CatFish naval drone and the development of a sonar sensor system for accurate object localisation and safe navigation in dynamic and uncertain underwater conditions. Through comprehensive experimentation and analysis, this thesis demonstrates the effectiveness of the proposed sensor system and sonar sensing system in enhancing underwater navigation and obstacle avoidance capabilities.

  5. 5. AUV SLAM constraint formation using side scan sonar

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Marco Schouten; [2022]
    Keywords : AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

    Abstract : Autonomous underwater vehicle (AUV) navigation has been a challenging problem for a long time. Navigation is challenging due to the drift present in underwater environments and the lack of precise localisation systems such as GPS. Therefore, the uncertainty of the vehicle’s pose grows with the mission’s duration. READ MORE
