@walid touzout, I believe rosbag could be the thing that you are looking for. While running the Gazebo or real world robot, you can record whichever topic you want into a bagfile as follows:

rosbag record -O bagfilename.bag /cmd_vel /robot_pose /other_topics_you_want..

I hope it helps! Don't forget to mark this comment as answer if it solves your problem.
