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.


Build a fully autonomous bot based on line follower mechanism which can detect colours and sound frequencies. The arena consists of various color coded checkpoints and 2 sound sources placed perpendicular to each other to avoid interference.

The bot has to identify the color of the checkpoint. If the color is GREEN then the bot has to move in the direction from where the sound is coming and if the color is RED the bot has to move in the direction opposite to the direction of approaching sound wave.
