  1. 16. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle in a GNSS-denied scenario

    University essay from Linköpings universitet/Reglerteknik

    Author : Alexander Källström; Albin Andersson Jagesten; [2020]
    Keywords : Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; Ultra-Wide Band; Proportional Navigation; GNSS-denied Scenario; Gazebo;

    Abstract : An autonomous system consisting of an unmanned aerial vehicle (UAV) in cooperation with an unmanned ground vehicle (UGV) is of interest in applications for military reconnaissance, surveillance and target acquisition (RSTA). The basic idea of such a system is to take advantage of the vehicles strengths and counteract their weaknesses. READ MORE

  3. 17. Autonomous and Accurate Landing of an Unmanned Aerial Vehicle

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Louise Tylstedt; Simon Ågren; [2020]
    Keywords : Technology and Engineering;

    Abstract : During recent years, advancements in mobile technology have enabled the development of quadcopters and unmanned aerial vehicles (UAV) to the point where their size and maneuverability enable indoor flight. In such GPS-denied environments, accurate positioning is a challenge which poses difficulties during flight, navigation and landing. READ MORE

  4. 18. Autonomous control of unmanned aerial multi-agent networks in confined spaces

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Sebastian Green; Pontus Månsson; [2019]
    Keywords : Technology and Engineering;

    Abstract : In this thesis, the functionality of existing Crazyflie models is extended to include current implementations of attitude and velocity control. The models are validated both as individual agents and as a swarm through comparisons of swarm behaviour during step, ramp and frequency response testing. READ MORE

  5. 19. Vision based control and landing of Micro aerial vehicles

    University essay from Karlstads universitet/Avdelningen för fysik och elektroteknik

    Author : Christoffer Karlsson; [2019]

  6. 20. Combined Control and Path Planning for a Micro Aerial Vehicle based on Non-linear MPC with Parametric Geometric Constraints

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Björn Lindqvist; [2019]
    Keywords : Non-linear MPC; MAV; Path Planning; Obstacle Avoidance; Robotics; UAV; MPC;

    Abstract : Using robots to navigate through un-mapped environments, specially man-made infrastructures, for the purpose of exploration or inspection is a topic that has gathered a lot of interest in the last years. Micro Aerial Vehicles (MAV's) have the mobility and agility to move quickly and access hard-to-reach areas where ground robots would fail, but using MAV's for that purpose comes with its own set of problems since any collision with the environment results in a crash.
