Grid solver Program

[vivan.bhalla93]

I am taking part in a grid solving competition in which i have to make a bot which will traverse through a graph and go at selected nodes and stop and blink there.
I need help in the programming.I am a complete newbie and this is the first time i am making a program for the bot.I have used atmega8 microcontroller and have used 4 sensor arrays.
Please someone help.
Thanks

What have you already done?
Is the Bot built? Any code written?

How does the Bot detect the 'grid'?
Is the 'grid' lines on the floor? If so then state with a line follower and change the code to count grid lines.

The forum here has lots of info an discussions. Try searching for 'line following', and 'maze solving'.
