    Sammanfattning : Connected devices have become an integral part of life in modern society. In the industry, several tasks have been automatized and are now performed by robots, a development that is called Industry 4.0. LÄS MER

  3. 7. Reinforcement Learning for Hydrobatic AUVs

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

    Författare :Grzegorz Woźniak; [2022]
    Nyckelord :Deep Reinforcement learning; Deep learning; Optimal control; Hydrobatics; Deep Reinforcement learning; Deep learning; Optimal control; Hydrobatics;

    Sammanfattning : This master thesis focuses on developing a Reinforcement Learning (RL) controller to perform hydrobatic maneuvers on an Autonomous Underwater Vehicle (AUV) successfully. This work also aims to analyze the robustness of the RL controller, as well as provide a comparison between RL algorithms and Proportional Integral Derivative (PID) control. LÄS MER

  4. 8. USING N-MODULAR REDUNDANCYWITH KALMAN FILTERS FORUNDERWATER VEHICLE POSITIONESTIMATION

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

    Författare :Axel Enquist; [2022]
    Nyckelord :MATLAB; Simulink; Kalman filter; n-Modular Redundancy; Underwater;

    Sammanfattning : Underwater navigation faces many problems with accurately estimating the absolute positionof an underwater vehicle. Neither Global Positioning system (GPS) nor Long Baseline (LBL) orShort Baseline (SBL) are possible to use for a military vehicle acting under stealth, since thesetechniques require the vehicle to be in the vicinity of a nearby ship or to surface and raise its antenna.

  5. 9. Autonomous Underwater Inspection of Caving Systems

    M1-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Filip Persson; [2022]
    Nyckelord :;

    Sammanfattning : This thesis aims to create and design a way for a unmanned underwater vehicle to navigateunderwater without the need for human interaction in order to carry out inspections of underwaterstructures or caving systems in a safe and effective manner. The inspection of underwater structuresor underwater caving systems is a difficult and expensive process. LÄS MER

  7. 10. AUV SLAM constraint formation using side scan sonar

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

    Författare :Marco Schouten; [2022]
    Nyckelord :AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

    Sammanfattning : 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. LÄS MER
