Hello

I was going through the costmap_2d_ros.cpp file, and there is a timer with 0.1 duration, that calls movementCB function, which updates the parameters robot_stopped_ and old_pose.
On searching for these two params int he whole navigation code, I didnt find anything that uses the values of these parameters.
