If you just want to build a line following robot, transistor or op amp is cheaper.

If in the future you want to expand on the robots abilities Arduino is better.

Then why not start with one of the documented Instructables to the right?
With no clue about it I fail to see what do you expect - certainly not that someone writes you build instructions and the code?
