  1. 1. Mobile Robot Traversability Mapping : For Outdoor Navigation

    Författare :Peter Nordin; Petter Krus; Jonas Nygårds; Nils Axel Andersen; Linköpings universitet; []
    Nyckelord :Traversability; Laser; Roughness; Mapping; Planning; Mobile robot; Navigation; Implementation;

    Sammanfattning : To avoid getting stuck or causing damage to a vehicle or its surroundings a driver must be able to identify obstacles and adapt speed to ground conditions. An automatically controlled vehicle must be able to handle these identifications and adjustments by itself using sensors, actuators and control software. LÄS MER

  3. 2. 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

  4. 3. Augmented navigation

    Författare :Gustav Burström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Spinal fixation procedures have the inherent risk of causing damage to vulnerable anatomical structures such as the spinal cord, nerve roots, and blood vessels. To prevent complications, several technological aids have been introduced. LÄS MER

  5. 4. Formations and Obstacle Avoidance in Mobile Robot Control

    Författare :Petter Ögren; KTH; []
    Nyckelord :Mobile Robots; Robot Control; Obstacle Avoidance; Multi-robot system; Formation Control; Navigation Function; Lyapunov Function; Model Predictive Control; Receding Horizon Control; Gradient Climbing; Gradient Estimation.;

    Sammanfattning : This thesis consists of four independent papers concerningthe control of mobile robots in the context of obstacleavoidance and formation keeping. The first paper describes a new theoreticallyv erifiableapproach to obstacle avoidance. LÄS MER

  7. 5. Towards On-line Learning Agents for Autonomous Navigation

    Författare :Guang Li; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; path-finding; head direction; artificial neural network; spatial representation; on-line learning; navigation; localization; autonomous mobile robot; obstacle avoidance; place learning;

    Sammanfattning : The design of a mechatronic agent capable of navigating autonomously in a changing and perhaps previously unfamiliar environment is a very challenging issue. This thesis addresses this issue from both functional and system perspectives. LÄS MER
