1. 16. Repeated Path Planning for Mobile Robots in Dynamic Environments

   Författare :Maarja Kruusmaa; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision-making; mobile robot; case-based reasoning; navigation; dynamic environments; path planning;

   Sammanfattning : This thesis presents a global navigation strategy for repeated traverse of mobile robots in dynamic environments. The research is motivated by the fact that most real-world applications of mobile robotics imply repeated traverse between predefined target points in large, uncertain real-world domains. LÄS MER

3. 17. Interpretation and Alignment of 2D Indoor Maps : Towards a Heterogeneous Map Representation

   Författare :Saeed Gholami Shahbandi; Björn Åstrand; Roland Philippsen; Antanas Verikas; Patric Jensfelt; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Mobile Robots; Autonomous Robots; Robot Perception; Robotic Mapping; Map Interpretation; Semantic Mapping; Place Categorization; Place Labeling; Semantic Annotation; Map Alignment; Region Segmentation; Region Decomposition; Map Representation; Heterogeneous Representation;

   Sammanfattning : Mobile robots are increasingly being used in automation solutions with notable examples in service robots, such as home-care, and warehouses. Autonomy of mobile robots is particularly challenging, since their work space is not deterministic, known a priori, or fully predictable. LÄS MER

4. 18. Local visual feature based localisation and mapping by mobile robots

   Författare :Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Sammanfattning : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. LÄS MER

5. 19. Communication-Aware Motion Planning for Mobile Robots

   Författare :Magnus Minnema Lindhé; Karl Henrik Johansson; Francesco Bullo; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomous systems; robotics; wireless sensor networks; motion planning; multipath fading;

   Sammanfattning : Mobile robots have found numerous applications in recent years, in areas such as consumer robotics, environmental monitoring, security and transportation. For information dissemination, multi-robot cooperation or operator intervention, reliable communications are important. LÄS MER

7. 20. Teaching mobile robots to use spatial words

   Författare :Simon Dobnik; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; situated interaction; spatial descriptions; language and perception; perceptual grounding; dialogue; natural language semantics; machine learning;

   Sammanfattning : The meaning of spatial words can only be evaluated by establishing a reference to the properties of the environment in which the word is used. For example, in order to evaluate what is to the left of something or how fast is fast in a given context, we need to evaluate properties such as the position of objects in the scene, their typical function and behaviour, the size of the scene and the perspective from which the scene is viewed.
