The task is to build a map of the environment using on-board sensors while at the same time localizing the robot relative to this map. Rao-Blackwellized particle filters have emerged as a powerful technique for solving the SLAM problem in a wide variety of environments. It is a well-known fact for sampling-based approaches that the choice of the proposal distribution greatly influences robustness and efficiency achievable by the algorithm. In this paper, we present an improved proposal distribution for grid-based SLAM with Rao-Blackwellized particle filters, which utilizes whole sequences of sensor measurements rather than only the most recent one. We have implemented our system on a real robot and evaluated its performance on standard datasets as well as in hard outdoor settings with few and ambiguous features. Our approach improves the localization accuracy and the map quality, substantially reducing the risk of mapping failures.<\/jats:p>","DOI":"10.1177\/0278364908097579","type":"journal-article","created":{"date-parts":[[2009,1,22]],"date-time":"2009-01-22T09:53:13Z","timestamp":1232617993000},"page":"191-200","source":"Crossref","is-referenced-by-count":13,"title":["Look-ahead Proposals for Robust Grid-based SLAM with Rao-Blackwellized Particle Filters"],"prefix":"10.1177","volume":"28","author":[{"given":"Slawomir","family":"Grzonka","sequence":"first","affiliation":[{"name":"University of Freiburg Department of Computer Science 79110 Freiburg, Germany, -freiburg.de"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Plagemann","sequence":"additional","affiliation":[{"name":"University of Freiburg Department of Computer Science 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgio","family":"Grisetti","sequence":"additional","affiliation":[{"name":"University of Freiburg Department of Computer Science 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfram","family":"Burgard","sequence":"additional","affiliation":[{"name":"University of Freiburg Department of Computer Science 79110 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,2,1]]},"reference":[{"key":"atypb1","volume-title":"Proceedings of the IEEE International Conference on Robotics & Automation (ICRA)","author":"Beevers, K."},{"key":"atypb2","volume-title":"Proceedings of the Conference on Uncertainty in Artificial Intelligence (UAI)","author":"Doucet, A."},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-3437-9"},{"key":"atypb4","volume-title":"Proceedings of the International Conference on Artificial Intelligence (IJCAI)","author":"Eliazar, A."},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1613\/jair.616"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2006.889486"},{"key":"atypb7","volume-title":"Proceedings of the IEEE\/RSJ International Conference on Intelligent Robots and Systems (IROS)","author":"Hahnel, D."},{"key":"atypb8","volume-title":"Robotics: Science and Systems","author":"Howard, A."},{"key":"atypb9","volume-title":"Proceedings of the International Conference on Artificial Intelligence (IJCAI)","author":"Montemerlo, M."},{"key":"atypb10","volume-title":"Proceedings of the National Conference on Artificial Intelligence (AAAI)","author":"Montemerlo, M."},{"key":"atypb11","volume-title":"Proceedings of the Conference on Neural Information Processing Systems (NIPS)","author":"Murphy, R."},{"key":"atypb12","volume-title":"Technical report, Department of Mathematics","author":"Pitt, M."},{"key":"atypb13","volume-title":"Proceedings of the IEEE\/RSJ International Conference on Intelligent Robots and Systems (IROS)","author":"Stachniss, C."},{"key":"atypb14","volume-title":"Probabilistic Robotics","author":"Thrun, S.","year":"2005"},{"key":"atypb15","volume-title":"Proceedings of the IEEE International Conference on Robotics & Automation (ICRA)","author":"Tipaldi, G."}],"container-title":["The International Journal of Robotics Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0278364908097579","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0278364908097579","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:16:37Z","timestamp":1777457797000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0278364908097579"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,2]]},"references-count":15,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2009,2]]}},"alternative-id":["10.1177\/0278364908097579"],"URL":"https:\/\/doi.org\/10.1177\/0278364908097579","relation":{},"ISSN":["0278-3649","1741-3176"],"issn-type":[{"value":"0278-3649","type":"print"},{"value":"1741-3176","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,2]]}}}
