  1. 6. Iterative Evaluation and Control Methods for Disturbance Suppression on a High Precision Motion Servo

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Claes Thunberg; Klara Kastensson; [2023]
    Keywords : Iterative feedback tuning; Iterative learning control; high precision motion control; Iterative methods for disturbance supression;

    Abstract : Moore’s law states that the number of transistors in an Integrated Circuit (IC) doubles every two years. Ever-increasing performance in mask writing machinery is therefore required being the first step in the manufacturing process. Many factors affect the quality of the end product, with the motion control system playing an important role. READ MORE

  3. 7. Enhancing GPR Measurements using Real Time Kinematics and LiDAR Mapping

    University essay from Umeå universitet/Institutionen för fysik

    Author : Christoffer Elebro; [2022]
    Keywords : GPS; GNSS; RTK; Lidar; 3D-mapping;

    Abstract : A Ground Penetrating Radar (GPR) is a non-invasive measurement tool to locate objects in the subsurface. The GPR transmits electromagnetic waves into the ground and records the waves reflected from surface interfaces of different materials. READ MORE

  4. 8. Submap Correspondences for Bathymetric SLAM Using Deep Neural Networks

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

    Author : Jiarui Tan; [2022]
    Keywords : Underwater simultaneous localization and mapping; Multibeam echosounder; Point cloud registration; Deep learning; Undervattens simultan lokalisering och kartläggning; Multibeam ekolod; Punktmolnsregistrering; Djupinlärning;

    Abstract : Underwater navigation is a key technology for exploring the oceans and exploiting their resources. For autonomous underwater vehicles (AUVs) to explore the marine environment efficiently and securely, underwater simultaneous localization and mapping (SLAM) systems are often indispensable due to the lack of the global positioning system (GPS).

  5. 9. Ultra-wideband location tracking of mobile devices

    University essay from Uppsala universitet/Signaler och system

    Author : Daniel Hietarinta; [2022]
    Keywords : UWB; ultra-wideband; GPS; tracking; locating; wireless communication; low-power; embedded systems; mobile devices; OTG; sensors; sensor fusion; mobile app; Android; dynamic anchors; ranging; C; Python;

    Abstract : Today’s most widely used tracking solutions for consumers involve the Global Positioning System (GPS) which meets most needs when it comes to rough estimation of location. GPS however is limited in accuracy with a horizontal error of around 5 meters and cannot be used in the areas where the satellites cannot provide a strong enough signal e.g. READ MORE

  6. 10. Real Time Lidar and ICP-Based Odometry in Dynamic Environments

    University essay from Linköpings universitet/Reglerteknik

    Author : Carl Hampus Hedén; Ludvig Hansson Granström; [2022]
    Keywords : ICP; Localization;

    Abstract : A robust and highly accurate positioning system is required to transition to fully autonomous vehicles in society.  This thesis investigates the potential for lidar sensors to be a part of a localization system, adding redundancy in case of an outage in a global navigation satellite system GNSS.
