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

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

   Abstract : 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.

   Abstract : Specific machines furnish the contemporary socio-technical imaginary: ‘Robot companions’ that supposedly herald the age of robots, an age that is signified by the realization of robot technologies that are taking over labor from humans in every sphere of ‘everyday human lives’. How do we want these robot companions to work and look and how do we want to live with these machines?  This thesis explores the engineering of relating humans and machines in the specific context of contemporary robotics from a queer feminist technoscience perspective.

6. 4. Thermo-electric temperature measurements in friction stir welding : Towards feedback control of temperature

   Author : Ana Magalhães; Gunnar Bolmsjö; Jeroen De Backer; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FSW; Robotic; Temperature; TWT; Plunge; Control; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Friction Stir Welding has seen a fast uptake in many industry segments. Mechanical properties superior to fusion welding, the ability to weld "unweldable" aluminium alloys and low distortion are often described as the main reasons for the fast industrial implementation of FSW. Most existing applications consist of long straight welding joints. READ MORE

7. 5. Towards Aerial Robotic Workers

   Author : Emil Fresk; Dimos Dimarogonas; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial Robotic Worker; UAV; Multirotor; Quadrotor; Estimation; Quaternion; Inertial Navigation; Reglerteknik; Control Engineering;

   Abstract : The aim of this thesis is to advance the control and estimation schemes for multirotors, and more specifically the Aerial Robotic Worker, in order to progress towards the necessary control and estimation performance for robust control, cooperation and collaboration. Towards this envisioned aim, this Licentiate thesis will present the following main research contributions: a) a singularity-free attitude controller for the attitude problem has been established, that does not have the inherent drawbacks of Euler angle or Direction Cosine Matrix based approaches, b) a generalized estimation scheme for attitude, position and parameter estimation will be presented that has the merit of low computational footprint, while it is robust towards magnetic disturbances and able to identify key parameters in the model of an Aerial Robotic Worker, c) an method for estimating the induced vibration frequencies on the multirotor’s frame, and the respective amplitudes, that relies on notch filtering for attenuating the induced vibrations, and d) a theoretical establishment, as well as an experimental development and evaluation of a variable pitch propeller model to add additional degrees of freedom and increase the robustness of an Aerial Robotic Worker.
