We can think of VT\u0026amp;R as a simple form of simultaneous localization and mapping (without the loop closures) along with a path-tracking controller; the idea is to pilot a robot manually along a route once and then be able to repeat the route (in its own tracks) autonomously many, many times using only visual feedback. VT\u0026amp;R is useful for such applications as load delivery (mining), sample return (space exploration), and perimeter patrol (security). Despite having demonstrated this technique for over 300 km of driving on several different robots, there are still many challenges we must meet before we can say this technique is ready for real-world applications. These include (i) visual scene changes such as lighting, (ii) physical scene changes such as path obstructions, and (iii) vehicle changes such as tire wear. I\u2019ll discuss our progress to date in addressing these issues and the next steps moving forward. There will be lots of videos.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EUnless otherwise noted, all seminars are held in room 1116 in the Marcus Nanotechnology Building from 12-1 p.m. Seminars are open to the public.\u003C\/p\u003E\u003Cp class=\u0022p1\u0022\u003ETimothy Barfoot, associate professor at the\u0026nbsp;University of Toronto, presents \u0022Towards Visual Route Following for Mobile Robots\u2026Forever!\u0022\u0026nbsp;as part of the RIM Seminar Series.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Barfoot of the University of Toronto presents \u0022Towards Visual Route Following for Mobile Robots\u2026Forever!\u0022 as part of the RIM Seminar Series."}],"uid":"27255","created_gmt":"2013-02-28 02:33:53","changed_gmt":"2016-10-08 02:02:46","author":"Josie Giles","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2013-03-20T13:00:00-04:00","event_time_end":"2013-03-20T14:00:00-04:00","event_time_end_last":"2013-03-20T14:00:00-04:00","gmt_time_start":"2013-03-20 17:00:00","gmt_time_end":"2013-03-20 18:00:00","gmt_time_end_last":"2013-03-20 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"195951":{"id":"195951","type":"image","title":"Timothy Barfoot","body":null,"created":"1449179906","gmt_created":"2015-12-03 21:58:26","changed":"1475894846","gmt_changed":"2016-10-08 02:47:26","alt":"Timothy Barfoot","file":{"fid":"196420","name":"tim-barfoot2.jpg","image_path":"\/sites\/default\/files\/images\/tim-barfoot2_0.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/tim-barfoot2_0.jpg","mime":"image\/jpeg","size":85614,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/tim-barfoot2_0.jpg?itok=B491nxRz"}}},"media_ids":["195951"],"related_links":[{"url":"http:\/\/asrl.utias.utoronto.ca\/~tdb\/","title":"Timothy Barfoot"},{"url":"http:\/\/robotics.gatech.edu\/","title":"Center for Robotics \u0026 Intelligent Machines"}],"groups":[{"id":"47223","name":"College of Computing"},{"id":"142761","name":"IRIM"}],"categories":[],"keywords":[{"id":"60061","name":"robot mobility"},{"id":"60041","name":"Robotics \u0026 Intelligent Machines Center (RIM)"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EJosie Giles\u003Cbr \/\u003ERIM Communications Officer\u003Cbr \/\u003E\u003Ca href=\u0022mailto:josie@gatech.edu\u0022\u003Ejosie@gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
