Realistic Simulation of Laser Range Finder Behavior in a Smoky Environment [chapter]

Okke Formsma, Nick Dijkshoorn, Sander van Noort, Arnoud Visser
2011 Lecture Notes in Computer Science  
In this paper, the behavior of a Hokuyo and Sick laser range finder in a smoky environment is studied.  ...  The Urban Search and Rescue Simulation used for RoboCup lacks realistic response of laser range finders on smoke.  ...  Acknowledgements We thank fire department trainings center BOCAS for usage of their facilities for our experiment, and in particular Jan Dirk van de Ven for his useful comments and Tom Groenendijk for  ...

Fusing sonars and LRF data to perform SLAM in reduced visibility scenarios

Joao Machado Santos, Micael S. Couceiro, David Portugal, Rui P. Rocha
2014 2014 IEEE International Conference on Autonomous Robot Systems and Competitions (ICARSC)  
The proposed method uses the complementary characteristics between a Laser Range Finder (LRF) and an array of sonars in order to ultimately map smoky environments.  ...  However, there are many situations which are not easily handled, such as the case of smoky, dusty, or foggy environments where commonly used range sensors for SLAM are highly disturbed by noise induced  ...  Helder Araújo for providing the Scout mobile robot used in the experiments.  ...

Symbol Statistics for Concept Formation in AI Agents

Jason R. Chen
2009 2009 IEEE/WIC/ACM International Joint Conference on Web Intelligence and Intelligent Agent Technology  
Our findings here suggest that such methods are necessary since a symbolic description of the true agent-environment interaction dynamics is often hidden among a background of non-representative descriptions  ...  We consider such data (from a mobile robot randomly roaming an office environment) and show how our method can correctly grow a set of true concepts from the data.  ...  each time step, like laser range finders, can be viewed as sets of scalar returning apparatus This search is exponential in ns and na.  ...

Relative localization and identification in a heterogeneous multi-robot system

Paolo Stegagno, Marco Cognetti, Lorenzo Rosa, Pietro Peliti, Giuseppe Oriolo
2013 2013 IEEE International Conference on Robotics and Automation  
We develop a localization method for a single-UAV/multi-UGV heterogeneous system of robots.  ...  Considering the natural supervisory role of the UAV and the challenging (but realistic) assumption that the UAV-to-UGV measurements do not include the identities of the UGVs, we have adopted the PHD filter  ...  For safety reasons it is designed to rely on on-board proximity sensors only (e.g. a laser range finder).  ...
