• A core activity of the project is our Lego Mars Rover. The Irish school was responsible for leading this activity and showing the other partners how to build it on the first short-term pupil exchange and teacher training mobility in Portugal. Different prototypes were built by the Irish pupils in order to come up with the simplest model that resembled the actual ExoMars Rover. The instructions below were shared with the other partners so that they could prepare for the assembly in Portugal.
