Now, though, a team of engineers from the Georgia Institute of Technology has studied the properties of the ant ball to discover that the insects strategically placed themselves in the formation depending on their size — findings that could inspire new design methods for material scientists and robotic technicians. The study, which was published in the _Journal of Experimental Biology_, revealed that the ants use adhesive pads on their legs to link together. They then position themselves perpendicularly in the formation, with the smaller ants lodging between bigger ants to maximize efficiency of space. Radhika Nagpal, a robot designer at Harvard University, believes that the discovery could help inspire simple robots that link together to solve a problem. She adds that the responsive robots could come in handy in extreme situations when there are limited resources. “Imagine robots that need to construct a barrier or patch a hole during a disaster response,” Nagpal explains in the journal _Nature_. The team of researchers thinks that along with helping in disaster responses, the discovery could also contribute to the design of “smart” materials that are able to respond to changes in the environment such as temperature and light. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/2863317/scientists-believe-mystery-behind-balls-of-ants-may-inspire-robotic-designs/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/2863317/scientists-believe-mystery-behind-balls-of-ants-may-inspire-robotic-designs/"},"headline":"Scientists Believe Mystery Behind Balls of Ants May Inspire Robotic Designs","datePublished":"2014-06-13T03:01:12.000Z","dateModified":"2026-02-21T08:22:34.562Z","description":"The methods in which ants link themselves together could inspire new robots to help with disaster response and materials that respond to changes in environment","url":"https://time.com/2863317/scientists-believe-mystery-behind-balls-of-ants-may-inspire-robotic-designs/","keywords":["robots","U.S.","Science topic"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltb2f8c6c6780d61df/6986973fe53aba0d714d31e3/157505924.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Melissa Hellmann","jobTitle":null,"url":"https://time.com/author/melissa-hellmann/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltb2f8c6c6780d61df/6986973fe53aba0d714d31e3/157505924.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"157505924","caption":"Fire ants link together to form a structure.","creditText":"Getty Images—Anders Boman","representativeOfPage":true}],"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/robots/","name":"robots"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/2863317/scientists-believe-mystery-behind-balls-of-ants-may-inspire-robotic-designs/","name":"Scientists Believe Mystery Behind Balls of Ants May Inspire Robotic Designs"}}]}] ```
