  2. 2. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

    Författare :Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

    Sammanfattning : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

  3. 3. Human Postural Sway Modeling and Balance Impairment Detection

    Författare :Hedyeh Jafari; Thomas Gustafsson; George Nikolakopoulos; Fredrik Öhberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : Falls, Fear of falling (FoF), and low balance confidence pose significant threats to health and independence among older people. This thesis aims to study humans’ postural and balance mechanisms, from analyzing the effect of multisensory inputs on balance performance and balance-related concerns to modeling the postural sway through physical dynamics and data-driven approaches.

  4. 4. Perception Aware Guidance Framework for Micro Aerial Vehicles

    Författare :Christoforos Kanellakis; George Nikolakopoulos; Danica Kragic; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perception driven control for MAVs; aerial inspection; vision based guidance for aerial manipulation; robots in low-light environments; Reglerteknik; Control Engineering;

    Sammanfattning : Micro Aerial Vehicles (MAVs) are platforms that have received significant research resources within robotics community, since they are characterized by simple mechanical design and versatile movement. These platforms possess capabilities that are suitable for complex task execution, in situations which are impossible or dangerous for the human operator to perform, as well as to reduce the operating costs and increase the overall efficiency of the operation.

  5. 5. Risk Aware Path Planning and Dynamic Obstacle Avoidance towards Enabling Safe Robotic Missions

    Författare :Samuel Karlsson; George Nikolakopoulos; Georgia Chalvatzaki; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotic; Path planning; Obstacle avoidanc; Robotic missions; licenti thesis; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Sammanfattning : This compilation thesis presents two main contributions in path planning and obstacle avoidance, as well as an integration of the proposed modules with other frameworks to enable resilient robotic missions in complex environments.In general, through different types of robotic missions it is important to have a collision tolerant and reliable system, both regarding potential risks from collisions with dynamic and static obstacles, but also to secure the overall mission success.
