  1. 1. Modelling, Control, and Experimental Evaluation of the Hovering Characteristics of a Tilt-Wing Unmanned Aerial Vehicle

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

    Author : Elias Small; [2017]
    Keywords : UAV; Tilt-Wing; Tilt Wing; Drone; UAS; Tricopter; PID; P-PI;

    Abstract : A Tilt-Wing Unmanned Aerial Vehicle (TW-UAV) and the preliminary evaluation of its hovering characteristics in extended simulation studies and experiments are presented in this Master Thesis. In the beginning, an overview of the TW-UAV's design properties are established, highlighting the novelties of the proposed structure and the overall merits. READ MORE

  2. 2. Decoupled Controllers for Mobile Manipulation with Aerial Robots : Design, Implementation and Test

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Riccardo Riccardo Zanella; [2016]
    Keywords : Mobile Manipulation; Aerial Robots; Quadrotor; Backstepping; Lyapunov-based Control.;

    Abstract : This work considers an aerial robot system composed of an Unmanned Aerial Vehicle (UAV) and a rigid manipulator, to be employed in mobile manipulation tasks. The strategy adopted for accomplishing the aerial manipulation is a decomposition of the previous system in two decoupled subsystems: one concerning the center of mass of the aerial robot; and another concerning the manipulator's orientation.

  3. 3. Exploring the use of 3D GIS as an analytical tool in archaeological excavation practice

    University essay from Lunds universitet/Arkeologi

    Author : Sjoerd Van Riel; [2016]
    Keywords : digital archaeology; archaeology; 3D models; 3D 4D GIS; photogrammetry; LIDAR; laser scanning; excavation methodology; excavation documentation; archaeological drawing methods; reflexivity; landscape archaeology; History and Archaeology;

    Abstract : Several digital technologies are now available to record and document archaeological excavations. A large number of studies have been published concerning the use of laser scanning, image based 3D modelling and GIS. READ MORE

  4. 4. Integration of IMU and Velodyne LiDAR sensor in an ICP-SLAM framework

    University essay from KTH/Optimeringslära och systemteori

    Author : Erik Zhang; [2016]
    Keywords : ;

    Abstract : Simultaneous localization and mapping (SLAM) of an unknown environment is a critical step for many autonomous processes. For this work, we propose a solution which does not rely on storing descriptors of the environment and performing descriptors filtering. READ MORE

  5. 5. Simultaneous Trajectory Optimization and Target Estimation Using RSS Measurements to Land a UAV

    University essay from Linköpings universitet/Reglerteknik

    Author : Jonathan Stenström; [2016]
    Keywords : EKF RSS; UAV; Autonomous landing; Trajectory optimization;

    Abstract : The use of autonomous UAV’s is a progressively expanding industry. This thesisfocuses on the landing procedure with the main goal to be independent of visualaids. That means that the landing site can be hidden from the air, the landingcan be done in bad weather conditions and in the dark. READ MORE
