Большинство мобильных роботов используют колёса, которые хорошо работают на ровных поверхностях, но бесполезны на неровной местности. Пассивно трансформируемое колесо PaTS-Wheel способно адаптироваться к препятствиям, меняя свою геометрию. Напечатанный механизм сочетает энергоэффективность и плавность хода с возможностью преодоления препятствий без использования датчиков или сложных механизмов.
