2. 1. Synergistic Strategies in Multi-Robot Systems: Exploring Task Assignment and Multi-Agent Pathfinding

   Author : Yifan Bai; George Nikolakopoulos; Tomi Westerlund; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous robots; Multi-robot systems; Task assignment; Multi-agent path-finding; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Abstract : Robots are increasingly utilized in industry for their capability to perform repetitive,complex tasks in environments unsuitable for humans. This surge in robotic applicationshas spurred research into Multi-Robot Systems (MRS), which aim to tackle complex tasksrequiring collaboration among multiple robots, thereby boosting overall efficiency.

4. 2. Towards 5G-Enabled Intelligent Machines

   Author : Gerasimos Damigos; George Nikolakopoulos; Johan Eker; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UAV; 5G; QoS; offloading; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Abstract : This thesis introduces a novel framework for enabling intelligent machines and robots with the fifth-generation (5G) cellular network technology. Autonomous robots, such as Unmanned Aerial Vehicles (UAVs), Autonomous Guided Vehicles (AGVs), and more, can notably benefit from multi-agent collaboration, human supervision, or operation guidance, as well as from external computational units such as cloud edge servers, in all of which a framework to utilize reliable communication infrastructure is needed.

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

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

   Abstract : 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.

6. 4. Human Postural Sway Modeling and Balance Impairment Detection

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

   Abstract : 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.

7. 5. Perception Aware Guidance Framework for Micro Aerial Vehicles

   Author : Christoforos Kanellakis; George Nikolakopoulos; Danica Kragic; Luleå tekniska universitet; []
   Keywords : 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;

   Abstract : 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.
