    Sammanfattning : In the last fifteen years, the Division of Electricity at Uppsala University has been developing a wave energy converter (WEC) concept. The concept is based on a point-absorbing buoy with a directly driven linear generator placed on the seabed. LÄS MER

  7. 5. Hydrobatics: Efficient and Agile Underwater Robots

    Författare :Sriharsha Bhat; Ivan Stenius; Dimos V. Dimarogonas; Alexander Phillips; KTH; []
    Nyckelord :Autonomous Underwater Vehicles; Modeling; Simulation; Control; Field Testing; Cyber-physical Systems.; Autonoma Undervattensfarkoster AUV ; Modellering; Simulering; Reglerteknik; Fältprovning; Cyber-fysikaliska System CPS .; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Hydrobatic capabilities in autonomous underwater vehicles (AUVs) can enable increased maneuverability without a sacrifice in efficiency and speed. This means innovative robot designs and new use case scenarios are possible. LÄS MER
