| 2018-07-09 14:08:03 -0500 | marked best answer | How to get robot Trajectory from move_base Hello, I am new to ROS, and I am currently working on an android app to guide people in an indoor environment. I am using a picture of the environment and I would like to show on it the robot trajectory as shown on rviz. Is it possible? I tried to use a subscriber to the topic /move_base/TrajectoryPlannerROS/global_plan but it seems like the same set of Path messages (x, y, z...) is published periodically whatever the goal is (I noticed that using rostopic echo), while on rviz the trajectory changes. Am I doing it wrong? Thank you in advance for your help Edit : Here is what I get on rviz (global plan in pink) :
And what my app draws basing on the x and y from position published on global_plan (the blue line)

| 2017-04-21 07:44:58 -0500 | commented answer | How to get robot Trajectory from move_base Or does move_base and global_plan do all the work? If so, how does rviz show a different path than the global_plan one?* |
| 2017-04-21 07:41:44 -0500 | commented answer | How to get robot Trajectory from move_base Thank you for your answer. The problem is that when, for example rviz shows a path avoiding obstacles, the path that is |
