  4. 3. Modeling and Control of Air-based Actuated Robots

    Författare :Andreas Papadimitriou; George Nikolakopoulos; Matteo Fumagalli; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Sammanfattning : The aim of this thesis is to advance and increase the quality of the field of maintenance and exploration with the use of air-based robotic platforms. The fields that will be addressed are focusing on: a) Identification of adhesion system of climbing robots, b) the control of adhesion level and motion of climbing robots, c) the path planning based on constraints posed from platforms’ mobility characteristics and sensor requirements and d) The attitude control of a morphing Micro Aerial Vehicle (MAV) during in-flight structural re-configurations.
