Hello every one .
I'm just a new one in the robots world

and I really need lots of help

My project : Fire Fighting robot - BUT with logic gates only .. and I you want to know why with logic gates ONLY ask my prof
any way ,, the point is to make the robot walk throw a maze - I attached it with the post - and find a candle - which represents the fire - .. and it have to fight it
My problem : I don't know how to make the robot walk by himself throw the maze

Can't make the path planning .. I think I have to use Sharp IR sensors to make it walk .. But I can't make it's logic design very well ..
What I do need : I want to know if It's right to use the IR sensor and how to make the logic design for the motion planning

.. so PLEASE HELP ME
