1. 16. Flexible, Efficient, and Scalable Autonomous Exploration and Volumetric Mapping

   Författare :Daniel Duberg; Patric Jensfelt; Cesar Cadena; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exploration; Mapping; Autonomous Exploration; Volumetric Mapping;

   Sammanfattning : Autonomous mobile robots have in recent years started to enter households in the form of autonomous vacuum cleaners and lawn mowers. The applicability of more advanced and general purpose service robots is almost endless. That is, robots that can perform a variety of tasks, instead of being specialized for a single task. LÄS MER

3. 17. Model-free execution monitoring in behavior-based mobile robotics

   Författare :Ola Pettersson; Alessandro Saffiotti; Lars Karlsson; Joachim Hertzberg; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; mobile robotics; execution monitoring; fault detection and isolation; diagnosis; data- och systemvetenskap; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : In the near future, autonomous mobile robots are expected to assist us by performing service tasks in many different areas, including transportation, cleaning, mining, or agriculture. In order to manage these tasks in a changing and partially unpredictable environment, without the help of humans, the robot must have the ability to plan its actions and to execute them robustly and in a safe way.

4. 18. Reactive navigation of an autonomous vehicle in underground mines

   Författare :Johan Larsson; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mobile Robots; Computer science; Datavetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : In most underground mines, LHD (Load-Haul-Dump) vehicles are used to transportore from the stope or muck-pile to a dumping point, and are typically operated by a human who is sitting on-board the vehicle. Generally, an underground mine does not offer the best working environment for humans, and the job of an LHD operator can be characterised as Three D: Dangerous, Dirty and Dull. LÄS MER

5. 19. From Ants to Service Robots : an Exploration in Stigmergy-Based Navigation Algorithms

   Författare :Ali Abdul Khaliq; Alessandro Saffiotti; Federico Pecora; Andrea Omicini; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stigmergy; Minimalistic Robots; Mobile robot navigation; RFID technology; Multi-robot system; Path planning; Localization; Map building;

   Sammanfattning : Navigation is a core functionality of mobile robots. To navigate autonomously, a mobile robot typically relies on internal maps, self-localization, and path planning. Reliable navigation usually comes at the cost of expensive sensors and often requires significant computational overhead. LÄS MER

7. 20. Functional understanding of space : Representing spatial knowledge using concepts grounded in an agent's purpose

   Författare :Kristoffer Sjöö; Patric Jensfelt; David Vernon; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatial representation; autonomous robots; spatial understanding; semantic mapping; spatial relations; visual search; robot search;

   Sammanfattning : This thesis examines the role of function in representations of space by robots - that is, dealing directly and explicitly with those aspects of space and objects in space that serve some purpose for the robot. It is suggested that taking function into account helps increase the generality and robustness of solutions in an unpredictable and complex world, and the suggestion is affirmed by several instantiations of functionally conceived spatial models.
