{{Short description|Three-dimensional objects designed to follow a desired path}}
A '''trajectoid''' is a three-dimensional object designed to follow a desired path. The term was coined by [[Bartosz Grzybowski]] and his colleagues from the [[Institute for Basic Science]] in [[Ulsan|Ulsan, South Korea]].<ref>{{Cite web |date=2023-08-14 |title=Shapes are programmed to roll along specific downhill paths |url=https://physicsworld.com/shapes-are-programmed-to-follow-specific-downhill-paths/ |access-date=2023-09-10 |website=Physics World |language=en-GB}}</ref> A mathematical [[algorithm]] to design trajectoids was developed by researchers in [[South Korea]] and a colleague from the [[University of Geneva]] in [[Switzerland]].<ref>{{Cite web |last=Yirka |first=Bob |last2=Phys.org |title=An algorithm that shapes objects to cause them to roll down ramps following a desired path |url=https://phys.org/news/2023-08-algorithm-ramps-desired-path.html |access-date=2023-09-10 |website=phys.org |language=en}}</ref><ref name=":0" /> These objects, and the ability to design them, may be useful in [[Mechanism (engineering)|mechanisms]] in the medical field or in industrial production. These applications have not been materialized and trajectoids are mainly an exercise of research.<ref name=":0">{{Cite web |last=Clark |first=Lindsay |title=Researchers' 'trajectoids' roll down pre-determined paths |url=https://www.theregister.com/2023/08/09/trajectoids_study/ |access-date=2023-09-10 |website=www.theregister.com |language=en}}</ref>
