Let's Make Robots!


QUESTION - Grid tracking robot


I am completely new to robot building and, in turn, new to this forum. I am currently studying Computer Science so I may be able to use some of what I know already to help.


Anyway, I have a basic idea in my head but I am asking for a little help on, how you think, it could work. It seems relatively easy in my head - for those that are used to robot building;


Area mapping

I have (that is relative because I have not yet ordered my first parts from Robotshop) a PING ultrasonic sensor. I'll be having an arduino mini - though I'll no doubt buy something bigger after - and I wonder if I can efficiently make my upcoming rover (differentially driven, nothing special really) map it's surrounding area using a grid. Is it possible or will I run short on memory with the arduino mini? And more importantly, I need help with the code (I have 0 experience with code, though I have enough theory I guess...). Any suggestions are appreciated.
