Benjamin Schmiedel (17) and Jannik Kühn (16) (from left to right) are delighted with second place and 2,000 euros. With their chip-controlled 'Dollycar', the students from the Karl Rehbein School in Hanau have developed a transport vehicle for camera movements in film. According to the duo, the new vehicle for amateur filmmakers enables spectacular and smooth filming. A great deal of effort was required to achieve this: The two students have extrapolated their working hours and come up with around 1,400 hours.
