1. 1. DRONAR: Obstacle echolocation using ego-noise

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Henrik Nilsson; [2023]
   Nyckelord :Drone; Autonomous systems; Obstacle avoidance; Sound; Noise; Planning; SONAR; Ego-noise; Multi-rotor aerial vehicle; Unmanned areal vehicle; Drönare; Autonoma system; Hinderundvikning; Ljud; Oljud; Planering; SONAR; Egenljud; Multirotorfordon; Obemannat luftfordon;

   Sammanfattning : You do not want your drone to crash. Therefore, safety systems should be put in place to prevent such an event, and obstacle avoidance is a major part of this. Today, the most successful techniques use cameras or light detection and ranging (LIDAR) to find and avoid obstacles; but to improve resiliency, multiple systems should be used. LÄS MER

3. 2. Rapidly-Exploring Random Trees for real-time combined Exploration andPath Planning

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Kalle Löfgren; [2023]
   Nyckelord :Robotics; RRT; ERRT; Exploration; Autonomous exploration; path planning; goal generation;

   Sammanfattning : The use of micro aerial vehicles (MAV) for civilian use such as exploration and inspection of varying structures, equipment and areas have garnered some interest as of late. MAVs have the mobility and agility to traverse three dimensional space quickly and access hard to reach areas where other alternatives would struggle, but a flying platform such as a MAV comes with it’s own set of distinct problems.

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

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

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

   Sammanfattning : 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. LÄS MER

5. 4. Localization of Combat Aircraft at High Altitude using Visual Odometry

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Jenny Nilsson Boij; [2022]
   Nyckelord :Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

   Sammanfattning : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. LÄS MER

7. 5. High density EMG based estimation of lower limb muscle characteristics using feature extraction

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Balázs Szabó; [2021]
   Nyckelord :HD-EMG; feature extraction; lower limb; muscle characteristics;

   Sammanfattning : Electromyography (EMG) is a common tool in electrical muscle activity measurement and can be used in multiple areas of clinical and biomedical applications, mainly in identifying neuromuscular diseases, analyzing movement or in human machine interfaces. Traditionally a pair of electrodes were used to measure the signals, but in recent years the use of high density surface EMG (HD-sEMG) gained more popularity as it can sample myoelectric activities from multiple electrodes in an array on a single muscle and provide more information.
