  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

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Akash Patel; [2021]
    Nyckelord :;

    Sammanfattning : Mars : The red planet has been on top in the priority list of interplanetary exploration of the solar system. The Mars exploration landers and rovers have laid the foundation of our understanding of the planet atmosphere and terrain. LÄS MER

  4. 3. Airborne Aircraft Detection for Multi-rotor Drones Feasibility Study of Robust Real-Time Long Distance Object Detection

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Hampus Falk; [2021]
    Nyckelord :;

    Sammanfattning : A drone is a light unmanned aerial vehicle capable of precise and agile movement. As these traits and the usability of drones are recognized in more domains, the necessity to ensure a safe airspace increases. LÄS MER

  5. 4. Geometric quality assessment of multi-rotor unmanned aerial vehicle borne remote sensing products for precision agriculture

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Jayan Wijesingha; [2016]
    Nyckelord :OrthoMosaic; blurriness; geometric accuracy; UAV; precision agriculture PA ; Digital Surface Model DSM ; geomatics; Physical Geography and Ecosystems Analysis; Earth and Environmental Sciences;

    Sammanfattning : Sub-meter level spatial resolution remote sensing products are essential for Precision Agriculture (PA) applications. Recent development of Unmanned Aerial Vehicle (UAV) with imaging sensors provides opportunity to generate sub-meter level, timely, and cloud free remote sensing products. LÄS MER

  7. 5. High Bandwidth Control of a Small Aerial Vehicle

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Magnus Blomberg; [2015]
    Nyckelord :linear quadratic control; singularly perturbed; multi-rotor;

    Sammanfattning : Small aerial vehicles such as quad-rotors have been widely used commercially, for research and for hobby for the last decade with use still growing. The high interest is mainly due to the vehicles being small, simple, cheap and versatile. Among rigid body dynamics fast dynamics exist cohering to motors and other fast actuators. LÄS MER
