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

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

    Abstract : 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. READ MORE

  4. 2. On Fundamental Elements of Visual Navigation Systems

    Author : Abujawad Rafid Siddiqui; J. Rafid Siddiqui; Sweden Karlskrona Blekinge Tekniska Högskola Institutionen för kommunikationssystem; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot navigation; localization; visual mapping; scene understanding; semantic mapping;

    Abstract : Visual navigation is a ubiquitous yet complex task which is performed by many species for the purpose of survival. Although visual navigation is actively being studied within the robotics community, the determination of elemental constituents of a robust visual navigation system remains a challenge. READ MORE

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

    Author : Victor Fernando Placido da Conceicao; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

  7. 5. Accuracy and Delay: An Inherent Trade-off in Cooperative UWB Navigation

    Author : Gabriel Garcia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; positioning; Ultra-wideband; navigation; MAC delay; localization.; S-TDMA;

    Abstract : Location-aware applications and wireless sensor networks are becoming essential in our daily lives from a commercial, and public perspectives. The need of localization information to drive the applications is a key requirement. New technologies have emerged to tackle the problem of the limitations of the Global Positioning System (GPS) solutions. READ MORE
