In particular, the nematode worm\u0026nbsp;\u003Cem\u003EC. elegans\u003C\/em\u003E\u0026nbsp;lives in environments (e.g., rotting fruit) where maneuverability is crucial to overcome heterogeneities and post-interaction deformations. To search for steering control principles in undulatory locomotion, we studied\u0026nbsp;\u003Cem\u003EC. elegans\u003C\/em\u003E\u0026nbsp;traversing both agar, liquid buffer, and lattices. These worms generate a time-dependent omega-like shape for reorientation to achieve high body rotation independent of the environment. Principal component analysis (PCA) revealed the worms use four principal components during turning, superimposing two body traveling waves with two spatial frequencies. A geometric mechanics framework rationalized the observed turning dynamics by properly coupling the amplitude and the phase of the two body traveling waves. These results and robophysical experiments, implementing the behavior, suggest that omega turns are a robust strategy for turning in diverse environments.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe seminar will be hosted at \u003Ca href=\u0022https:\/\/bluejeans.com\/558060212\u0022\u003Ethis bluejeans link\u003C\/a\u003E.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cem\u003EQBioS 4th year student Kelimar Diaz (homeschool of physics), advised by Daniel Goldman, will present \u0026quot;Maneuvering strategies of C. elegans locomotion in heterogeneous environments\u0026quot;\u003C\/em\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"QBioS Student Seminar Series - Kelimar Diaz"}],"uid":"35673","created_gmt":"2021-02-15 15:05:29","changed_gmt":"2021-02-15 15:05:29","author":"dmuratore3","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-02-18T16:00:00-05:00","event_time_end":"2021-02-18T17:00:00-05:00","event_time_end_last":"2021-02-18T17:00:00-05:00","gmt_time_start":"2021-02-18 21:00:00","gmt_time_end":"2021-02-18 22:00:00","gmt_time_end_last":"2021-02-18 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"644230":{"id":"644230","type":"image","title":"02_18_qbios_seminar_flyer","body":null,"created":"1613400777","gmt_created":"2021-02-15 14:52:57","changed":"1613400777","gmt_changed":"2021-02-15 14:52:57","alt":"","file":{"fid":"244587","name":"02_18_announcement.png","image_path":"\/sites\/default\/files\/images\/02_18_announcement.png","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/02_18_announcement.png","mime":"image\/png","size":143964,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/02_18_announcement.png?itok=zx0SWijL"}}},"media_ids":["644230"],"groups":[{"id":"562111","name":"QBioS"}],"categories":[],"keywords":[{"id":"138191","name":"go-qbios"},{"id":"147941","name":"go_qbios"},{"id":"168667","name":"QBioS"},{"id":"182721","name":"Qbios seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"177814","name":"Postdoc"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EBluejeans link for the seminar is available\u0026nbsp;\u003Ca href=\u0022https:\/\/bluejeans.com\/558060212\u0022\u003Ehere\u003C\/a\u003E.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EContact Daniel Muratore (\u003Ca href=\u0022https:\/\/qbios.gatech.edu\/people\/Daniel%20Muratore\u0022\u003Ehere\u003C\/a\u003E) for questions.\u0026nbsp;\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
