When the motors are powered on, it starts writhing, executing complicated squashing and stretching motions and occasionally flinging itself into the air, all the while slowly making its way up a bumpy foam ramp.\u0026nbsp;The odd wheel\u0026rsquo;s unorthodox mode of travel exemplifies a recent trend: Physicists are finding ways to get useful collective behavior to spontaneously emerge in robots assembled from simple parts that obey simple rules. \u003Ca href=\u0022https:\/\/physics.gatech.edu\/user\/daniel-goldman\u0022\u003EDaniel Goldman\u003C\/a\u003E, Dunn Family Professor in the \u003Ca href=\u0022https:\/\/physics.gatech.edu\u0022\u003ESchool of Physics\u003C\/a\u003E\u0026nbsp;(who did not work on the odd wheel \u003Ca href=\u0022https:\/\/arxiv.org\/abs\/2108.08837\u0022\u003Estudy\u003C\/a\u003E), uses the term\u0026nbsp;\u0026quot;robophysics\u0026quot; to describe this latest trend in robotics.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"34434","created_gmt":"2022-11-01 15:11:12","changed_gmt":"2022-11-01 15:11:12","author":"Renay San Miguel","boilerplate_text":"","field_publication":"","field_article_url":"","publication_url":"https:\/\/www.wired.com\/story\/a-wheel-made-of-odd-matter-spontaneously-rolls-uphill\/","dateline":{"date":"2022-09-25T00:00:00-04:00","iso_date":"2022-09-25T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"groups":[{"id":"1278","name":"College of Sciences"}],"categories":[{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"4896","name":"College of Sciences"},{"id":"166937","name":"School of Physics"},{"id":"12040","name":"Daniel Goldman"},{"id":"170450","name":"robophysics"},{"id":"667","name":"robotics"},{"id":"191568","name":"wheels"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
