The acronym mint is widely used in the German-speaking countries for what is commonly referred to as STEM (science, technology, engineering, and math) in the English-speaking world.

mint & pepper creates modules that young people can use to learn more about these subjects. The modules also enable them to take advantage of their existing knowledge to solve new problems and apply that knowledge to real-life situations. The moderate use of new technologies, where appropriate, is paramount.

One successful module, called “DanceBot: Build Your Own Robot to Dance to Your Favorite Music,” allows participants to solder, assemble, program and decorate their own robots.

The mint & pepper portfolio includes learning modules for the upper primary school level and  secondary school levels I and II. Each module is tailored to a specific level and can be used as part of practical instruction in schools, as well as in public or university events and extracurricular learning environments.

mint & pepper was launched as an initiative of the Autonomous Systems Lab and the Department of Mechanical and Process Engineering at ETH Zurich.

The project is supported by the following partners: Gebert Rüf Stiftung, Wyss Zurich, ETH Zurich, University of Zurich, Department of Mechanical and Process Engineering (D-MAVT), Department of Information and Electrical Engineering (D-ITET), Department of Materials (D-MATL), IngCH, Rosie,, Switzerland Innovation Park, Swisscom, Digital Switzerland, and the MINT Learning Center at ETH Zurich.
