Last March, during Arduino Day in Zaragoza, four guys met for the first time and  then decided to participate to the Nasa Challenge collaborating to the project made by Carlos Sicilia Til in the previews months:

OpenCuriosity is an open source, exomars rover (1:5 scale) with Arduino as main controller, based on the NASA Curiosity Rover. It contains a set of Arduino boards and sensors. The general public will be allowed to use these Arduinos and sensors for their own creative purposes while they are in space. All the people will be allowed to integrate their project in the robot, and the data gathered will be available on the internet in order to share this information with the general public for educational, science or other purposes. We want to provide affordable space exploration for everyone!

The robot designed by the Aragonese team is now among the finalists of the NASA contest!
