1. 1. Occlusion-Aware Autonomous Highway Driving : Tracking safe velocity bounds on potential hidden traffic for improved trajectory planning

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jonne van Haastregt; [2023]
   Keywords : Autonomous Driving; Occlusion-Awareness; Reachability Analysis; Highway driving; Formal Safety; Autonom Körning; Skymd-sikt-medveten; Nåbarhetsanalys; Motorvägskörning; Formell Säkerhet;

   Abstract : In order to reach higher levels of autonomy in autonomous driving, it is important to consider potential occluded traffic participants. Current research has considered occlusion-aware autonomous driving in urban situations. READ MORE

3. 2. Scalable Reinforcement Learning for Formation Control with Collision Avoidance : Localized policy gradient algorithm with continuous state and action space

   University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Andreu Matoses Gimenez; [2023]
   Keywords : Control theory; Multi-agent systems; Distributed systems; Formation control; Collision avoidance; Reinforcement learning; Teoria de control; Sistemes multiagent; Sistemes distribuïts; Control de formació; Prevenció de col·lisions; Reinforcement Learning; Reglerteknik; Multi-agent system; Distribuerade system; formationskontroll; Kollisionsundvikande; Reinforcement learning; Teoría de control; Sistemas multiagente; Sistemas distribuidos; Control de formación; Prevención de colisiones; Reinforcement Learning;

   Abstract : In the last decades, significant theoretical advances have been made on the field of distributed mulit-agent control theory. One of the most common systems that can be modelled as multi-agent systems are the so called formation control problems, in which a network of mobile agents is controlled to move towards a desired final formation.

4. 3. Trajectory Optimisation of a Spacecraft Swarm Maximising Gravitational Signal

   University essay from KTH/Optimeringslära och systemteori

   Author : Rasmus Maråk; [2023]
   Keywords : Spacecraft Swarms; Trajectory Optimisation; Impulsive Manoeuvres; Evolutionary Algorithms; Polyhedral Gravity Model; Small Body Exploration; Discrete Spherical Grids; Svärmande rymdfarkoster; Banoptimering; Impulsiva manövrar; Evolutionära Algoritmer; Polyhedral gravitationsmodell; Utforksning av små kroppar i solsystemet; Diskreta sfäriska rutnät;

   Abstract : Proper modelling of the gravitational fields of irregularly shaped asteroids and comets is an essential yet challenging part of any spacecraft visit and flyby to these bodies. Accurate density representations provide crucial information for proximity missions, which rely heavily on it to design safe and efficient trajectories. READ MORE

5. 4. Intelligent Drone Swarms : Motion planning and safe collision avoidance control of autonomous drone swarms

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Hilding Gunnarsson; Adam Åsbrink; [2022]
   Keywords : Artificial Potential Field APF ; Control Barrier Function CBF ; Leader Follower control; Micro Aerial Vehicle MAV ; Optimal motion planning;

   Abstract : The use of unmanned aerial vehicles (UAV), so-called drones, has been growingrapidly in the last decade. Today, they are used for, among other things, monitoring missions and inspections of places that are difficult for people to access. Toefficiently and robustly execute these types of missions, a swarm of drones maybe used, i.e. READ MORE

6. 5. Autonomous Underwater Inspection of Caving Systems

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Filip Persson; [2022]
   Keywords : ;

   Abstract : This thesis aims to create and design a way for a unmanned underwater vehicle to navigateunderwater without the need for human interaction in order to carry out inspections of underwaterstructures or caving systems in a safe and effective manner. The inspection of underwater structuresor underwater caving systems is a difficult and expensive process. READ MORE
