A robot is usually an electro-mechanical machine which is guided by computer or electronic programming. Conventional line tracer robots follow path in given map. In some kind of robots path is already store in its memory and it simply follows that path. When such types of robots are left to traverse through any random maze, these robots tend to traverse all possible paths every time having no facility to remember the right path. In the authors' robot they are providing it with the capability to traverse through any random maze and remember the right path. Thus when robot travels through the same maze again it knows which is the right path to reach destination.
