  1. 1. Low-Cost Navigation Systems : A Study of Four Problems

    Författare :Isaac Skog; Peter Händel; Fredrik Gustafsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Navigation; Inertial Navigation; Pedestrian Navigation; Inertial Measurement Unit; Time Synchronization; Signal processing; Signalbehandling;

    Sammanfattning : Today the area of high-cost and high-performance navigation for vehicles is a well-developed field. The challenge now is to develop high-performance navigation systems using low-cost sensortechnology. LÄS MER

  3. 2. Escaping 'death by GPS' : foundations for adaptive navigation assistance

    Författare :Fateme Teimouri; Kai-Florian Richter; Henrik Björklund; Sabine Timpf; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wayfinding; navigation systems; navigation complexity; prominent locations; route generalization; spatial cognition; mental models; route learning; direction giving; Human-centered study.;

    Sammanfattning : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. LÄS MER

  4. 3. Indoor Navigation for Mobile Robots : Control and Representations

    Författare :Philipp Althaus; KTH; []
    Nyckelord :mobile robots; robot navigation; indoor navigation; behaviour based robotics; hybrid deliberative systems; dynamical systems approach; topological maps; symbol anchoring; autonomous mapping; human-robot interaction;

    Sammanfattning : This thesis deals with various aspects of indoor navigationfor mobile robots. For a system that moves around in ahousehold or office environment,two major problems must betackled. First, an appropriate control scheme has to bedesigned in order to navigate the platform. Second, the form ofrepresentations of the environment must be chosen. LÄS MER

  5. 4. Designing for Safe Maritime Navigation. Studying Control Processes for Bridge Teams

    Författare :Victor Fernando Placido da Conceicao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; safety; Socio-technical Systems; navigation control; joint cognitive systems; e-Navigation; human factors; pilotage;

    Sammanfattning : Several technological advances have been seen the maritime domain to achieve higher operational efficiency and to address the generally recognised causes of most maritime accidents. The International Maritime Organization (IMO) endorses the use of best available technology to “drive continuous improvement and innovation in the facilitation of maritime traffic” in line with the goal of sustainable development.

  7. 5. Inertial Navigation and Mapping for Autonomous Vehicles

    Författare :Martin Skoglund; Fredrik Gustafsson; Thomas Schön; Tim Bailey; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SLAM; Inertial Navigation; Filtering; Smoothing; Cameras; Optimisation; Autonomous;

    Sammanfattning : Navigation and mapping in unknown environments is an important building block for increased autonomy of unmanned vehicles, since external positioning systems can be susceptible to interference or simply being inaccessible. Navigation and mapping require signal processing of vehicle sensor data to estimate motion relative to the surrounding environment and to simultaneously estimate various properties of the surrounding environment.
