If it is possible to convert x,y values to velocity value then it will be easy to move robot inside gazebo .

Why do you want to use coordinates if you don't have a map ?

To move a robot you just need to send velocity commands to it. Since you are using a turtlebot you should have a topic /cmd_vel available. Publishing to this topic will allow you to control the robot.

if the OP feels looking at relative displacement suffices, then using Odom and closing the loop with a position controller using the Twist interface would be an OK approach.

There are many topics about this already on this site though. @harrynick: I'd recommend you search using Google. Append to your query.

Actually my scenario is like this, i have tracked the path followed by human in an environment which is basically in (x,y) co-ordinate form. I want my robot to move in this path, for that i have to convert this (x,y) co-ordinates to cmd_vel values. How it will be possible?any ideas??
