  1. 11. An investigation of hybrid maps for mobile robots

    Författare :Pär Buschka; Alessandro Saffiotti; Christian Freksa; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile robot; Hybrid map; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : Autonomous robots typically rely on internal representations of the environment, or maps, to plan and execute their tasks. Several types of maps have been proposed in the literature, and there is general consensus that different types have different advantages and limitations, and that each type is more suited to certain tasks and less to others.

  3. 12. Conflict-Free Routing of Mobile Robots

    Författare :Sabino Francesco Roselli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SMT; Job Shop; Bin Sorting; Vehicle Routing; MILP;

    Sammanfattning : The recent advances in perception have enabled the development of more autonomous mobile robots in the sense that they can operate in a more dynamic environment where obstacles surrounding the robot emerge, disappear, and move. The increased perception of Autonomous Mobile Robots (AMRs) allows them to plan detailed on-line trajectories in order to avoid previously unforeseen obstacles, making AMRs useful in dynamic environments where humans, traditional fork-lifts, and also other mobile robots operate.

  4. 13. On methods for assistive mobile robots

    Författare :Sven Rönnbäck; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis makes a contribution to the field of autonomous vehicles, especially for use on assistive wheelchairs. Methods and technologies for topological signature maps, obstacle avoidance, door passing, localization, and navigation are presented. LÄS MER

  5. 14. 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. 15. Plan-Based Configuration of a Group of Robots

    Författare :Robert Lundh; Alessandro Saffiotti; Lars Karlsson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile Robots; Computer science; Datavetenskap; Computer Science; datalogi;

    Sammanfattning : Imagine the following situation. You give your favorite robot, named Pippi, the task to fetch a parcel that just arrived at your front door. While pushing the parcel back to you, she must travel through a door opening. Unfortunately, the parcel she is pushing is blocking her camera, giving her a hard time to see the door to cross. LÄS MER
