hi, i want to make a GPS enabled robot with arduino but it will be my first project.so, can u give me some idea how to make a robot which follow the direction to go to a particular place by using GPS. and any link where i get the step by step process to make one.
You haven't said what sort of robot this is to be - ground-based, or aerial.

This is at a minimum a three stage process. First, you get the Arduino so it can get GPS data, and tell YOU which way to go to get from point A (where you are) to point B (where you said you wanted to go).
Then, you build a robot that can go somewhere when you give it "go left", "go right", "go forward", "stop, damn it" type instructions by whatever means.
Finally, you make the robot go where you want based on the GPS data.
There is no step by step guide for dummies to a project of this complexity. You must bring some effort/intelligence/skills to the table.
AWOL , i want to make a ground based robot
What sensors do you envisage for object avoidance?
How big is the playing field?
AWOL , for object avoidance i want to use ultrasonic sensors and area will be a football ground
On the scale of a football field, GPS errors will be quite significant, even with techniques like WAAS (assuming you have WAAS coverage).
Will you be using differential GPS?
After that, it is all down to Pythagorus.
can i use this mobile platform or i have to take another one. http://www.robotshop.com/dfrobot-4wd-arduino-mobile-platform-3.html
and i try to find a DGPS system but didn't get any useful link. can u suggest something?
