R2t2 Mars Mission
The year is 2032 and a meteorite has damaged a power station on Mars.
16 teams of school aged children spread across the world have each been given control of a robot based on Mars and have been commanded to work together to asses the damage and restart the main generator. The teams will need to program the robots taking into account the time lag taken for instructions to travel from planet Earth to Mars (between 3 and 21 minutes depending on the orbit) in order to get the generator restarted in time.
The R2t2 event took place during several years at the Swiss Robotics (Industry) Day, with teams competing from across the world. For more information and to watch along, please see their website.
