this robot must be able to follow a path and avoid obstacles.

This robot? We haven't a clue what "this robot" is.

How is the path defined? How is the Arduino supposed to know where the path is?

How is the Arduino supposed to know where the obstacles are? How is is supposed to deal with them? Always turn left? Always turn right? Turn randomly? How is the robot supposed to find the path again?
