Can anyone suggest me a technique ?

Your robot could have one ball in the center in contact with the ground and then X and Y counter wheels that pulse count its movement. Heck you could probably hack a computer mouse to do it. Then once you set it's home position, you can locate the robot using an X and Y position from the 0,0 home position. Realize that if the robot gets lifted or sufficiently bumped that all bets are off. You could consider a combination of methods, to keep your accuracy . A top down view will probably be the most accurate method though. Good luck!
