From the project

Кружок робототехники RoboWay

Мы запускаем образовательный кружок робототехники RoboWay для подростков в возрасте от 12 до 18 лет (возможны исключения в зависимости от подготовки ребенка). Цель кружка — дать учащимся фундаментальные знания в области электроники, программирования и робототехники.

В отличие от большинства кружков, где используются готовые наборы и работа сводится к сборке по инструкции, в RoboWay участники будут разрабатывать и изготавливать роботов с нуля. Мы стремимся к тому, чтобы дети осознанно подходили к техническому творчеству и понимали принципы работы систем, а не просто следовали пошаговым…
