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.

Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage.
