Satellites made Marvin’s day by signalling the presence of water on his barren red planet. With an adrenaline rush through his veins, he takes his sensors and instruments and steps out but oops! How does he get there? Images show coloured spots and some frequency generators on the way and for now, that seems to be his only clue. He looks back at you for help. Create an autonomous line follower which determines its course based on coloured checkpoints and frequency sources placed at different spots in this strange little place.
