In an experiential way, the children tried fields such as robotics and programming, 3D printing, pneumatics, electropneumatics and hydraulics. The children could see the technical equipment of the mobile classroom, get an idea of pneumatic circuits and 3D printing technology. They assembled their pneumatic circuit according to the diagram, designed and printed a small object, for example a key ring, programmed a robot or assembled a project from an electronic Boffin kit.
