Eschweg students win the Hesse Solar Cup with an innovative robot!
A great success for the Brothers Grimm School in Eschwege: The two 13-year-old students Elias Beck and Elias Heeren triumphed at the Hessen Solarcup 2025 in Kassel. They not only won first place in the overall ranking, but also secured the special prize for the best poster. In doing so, they set an example for technical know-how and creativity in the school environment. Werra-Rundschau reports.
The two Elias’s competed in the solar robot category with their solar-powered robot “Bob”. Their challenge was to develop a robot that could independently drive on a three-lane racetrack and skillfully change lanes in the curves. This technical trick was made possible by an infrared remote control, which not only earned the team special technical points, but also the respect of the jury. With speed and reliability, “Bob” was a high flyer – in three crucial races in which the highest number of laps was determined.
Teamwork and hard work
After the Easter holidays there was a lot of screwing, programming and planning. The students put a lot of time into their project day and night – true to the motto “Where there is a will, there is a way”. They received support from their school's Lego Robotics AG as well as from the MINT workshop at the University of Kassel and the school Mint-Up AG. Her team, also called E², was the youngest in the competition and beat five other teams.
At the competition day, which took place on June 13th, the two impressed the jury with their posters - one of which even discussed the energy transition. This selection of topics shows how important such events are, not only for technical development, but also for the promotion of sustainable ideas. The University of Kassel highlights that the Hessen Solarcup focuses on the application of technology with solar energy and energy efficiency.
A look at the future
The two students are hungry for more and plan to further develop their robot next year to get a little closer to real overtaking maneuvers. This not only shows their ambition, but also that technical understanding and teamwork are highly valued.
Events like the Hessen Solarcup are not just a competition, but also an important part of MINT funding, where young talents can demonstrate their skills in innovative projects. Hands on Technology highlights that such events promote exchange between MINT talents and offer valuable experiences.
