  1. 6. Robust execution of robot task-plans : a knowledge-based approach

    Författare :Abdelbaki Bouguerra; Lars Karlsson; Alessandro Saffiotti; Froduald Kabanza; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autonomous mobile robots; plan execution and monitoring; semantic knowledge; cognitive robotics.; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : Autonomous mobile robots are being developed with the aim of accomplishing complex tasks in different environments, including human habitats as well as less friendly places, such as distant planets and underwater regions. A major challenge faced by such robots is to make sure that their actions are executed correctly and reliably, despite the dynamics and the uncertainty inherent in their working space. LÄS MER

  3. 7. Automation of underwater operations on wave energy converters using remotely operated vehicles

    Författare :Flore Remouit; Jens Engström; Antonio Pascoal; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remotely Operated Vehicles; wave energy; WEC deployment; cable connection; optical positioning system; autonomous underwater docking;

    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

  4. 8. On control under communicaiton constraints in autonomous multi-robot systems

    Författare :Alberto Speranzon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : Multi-robot systems have important applications, such as space explorations, underwater missions, and surveillance operations. In most of these cases robots need to exchange data through communication. Limitations in the communication system however impose constraints on the design of coordination strategies. LÄS MER

  5. 9. Hydrobatics: Real-time Control, Simulation and Learning for Underactuated AUVs in Agile Maneuvers

    Författare :Sriharsha Bhat; Ivan Stenius; Dimos V. Dimarogonas; Massimo Caccia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utonomous Underwater Vehicles; Underactuated Systems; Model Predictive Control; Hybrid Systems; Simulation; System Identification; Adaptive Sampling; Cyber-physical Systems.; Autonoma Undervattensfarkoster AUV ; Modellering; Simulering; Modelprediktiv kontroll MPC ; Systemidentifiering; Adaptiv mätning; Fältförsök; Cyber-fysikaliska System CPS .; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Underwater robots such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) are either designed as flight style, optimized for range and speed, or hover style, optimized for precise maneuverability.

  7. 10. Optimizing Ocean Feature Estimation and Tracking through Adaptive Sampling and Formation Control of Autonomous Underwater Vehicles

    Författare :Joana Filipa Gouveia Fonseca; Karl H. Johansson; Nina Mahmoudian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Increased ocean temperatures caused by climate change are expected to lead to more frequent and severe harmful algal blooms, which deteriorate water quality, cause human illness and fish mortality. Scientific understanding of algal blooms and their dynamics is limited due to the lack of data from such ocean phenomena. LÄS MER
