line maze solver

[kraz_elec]

i wanted to make a line maze solver similar to 3pi robot (www.pololu.com/catalog/product/975) ..can we use at89s52??..it has only 256 bytes ram..is 256 bytes of ram sufficient??..please help..

It depends on the size of the maze. It also depends on the other variables in your program. But your robot should be able to save one
intersection for every byte of ram you have available. So you should easily be able to work with a maze of 200+ intersections. The key
is to use the ram wisely.

please tell me little more about using ram wisely...

Try to reduce the actual program to the smallest possible. Also, if the maze is a choice of left/right, you could probably use individual bits for the buffer, so that will give you a ton more memory.

thank you for guiding me ..

3 ways to do a maze are a wall hugger, random left or right turns, or making a map and finding the shortest way through it.

Yeah, a wall hugger would probably be the best option here.
