  1. 1. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

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

    Författare :Somnath Balaji Suresh Kumar; [2023]
    Nyckelord :Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

    Sammanfattning : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

  3. 2. Design Development of a Hydrostat : Construction of a hydrostat used in an underwater SAI-unit

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Abbas Mohammadi; [2021]
    Nyckelord :Hydrostat; Saab Dynamics; Design; UNNDEX; Pressure;

    Sammanfattning : Working with and providing different military and industrial solutions, SBD’s (Saab Dynamic) work also involve underwater equipment and underwater weapon (UW) systems. Nowadays, there are a number of standards that should be followed to make weapon systems safe to use, transport and handle. LÄS MER

  4. 3. Sharkbait - A self-stabilising underwater drone : Evalution of response time, propulsion and steering in a underwater environment

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Victor Hanefors; Shaya Rahmanian; [2019]
    Nyckelord :Mechatronics; Drone; Underwater; Self-stabilisation; Mekatronik; Drönare; Undervatten; Självstabiliserande;

    Sammanfattning : This projects purpose was to build an underwater remote operated vehicle with software controlled self-stabilisation for evaluation of the response time, propulsion and steering to see what could be achieved. A prototype was constructed and tested in dry conditions at first. LÄS MER

  5. 4. Kombinerad förundersökning för tunnlar med resistivitet och refraktionsseismik i urban undervattensmiljö

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Elisabeth Lindvall; Erik Warberg Larsson; [2016]
    Nyckelord :Geophysics; underground; structures; tunneling; construction; urban; TRUST; seismic; resistivity; underwater; survey; geofysik; resistivitet; seismik; undervatten; undersökning; Technology and Engineering;

    Sammanfattning : Due to expanding cities and increasing population infrastructure needs to expand in a safe and sustainable way with little effect on the environment and economy. Years of urbanization doesn’t make it easy, no free spaces are available and culture marked buildings are protected. The only alternative left is to construct in layers. LÄS MER
