Researchers took their observations and contacted a lab that develops robot sidewinders to further explore the movement. After a robot snake named Elizabeth was unable to scale a desert dune in Egypt, they brought Elizabeth to a _fake_ dune in Atlanta, where “she” ultimately found more success after researchers applied the flattening technique to her movements. Following that breakthrough, playing with Elizabeth’s settings gave the scientists insight into how sidewinders move so effortlessly. As it turns out, an out-of-sync combination of left-and-right motions and up-and-down movements working their way down the body helps keep the sand stable underneath the snake, to avoid slipping. The flattening motion helps keep the snake’s contact with the sand at the ideal, moderate amount. Too much contact and the snake can slip; too little, and it can’t successfully scale. \[[_BBC_](http://www.bbc.com/news/science-environment-29523851 "undefined")\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3500346/robot-snakes-sidewinders/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3500346/robot-snakes-sidewinders/"},"headline":"Robot Snakes Teach Scientists How Sidewinders Move","datePublished":"2014-10-12T20:25:48.000Z","dateModified":"2026-02-21T10:44:14.999Z","description":"Elizabeth the robot snake gave scientists insight into sand dune travel","url":"https://time.com/3500346/robot-snakes-sidewinders/","keywords":["animals","Snakes"],"thumbnailUrl":"","author":[{"@type":"Person","name":"Nolan Feeney","jobTitle":null,"url":"https://time.com/author/nolan-feeney/"}],"articleSection":"Science","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/animals/","name":"animals"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3500346/robot-snakes-sidewinders/","name":"Robot Snakes Teach Scientists How Sidewinders Move"}}]}] ```
