Hi all, I have the slam_gmapping package up an running. I am trying to extract the full, slam-corrected pose history of the robot at any given point during the mapping process. I know that gmapping node publishes a map → odom transform. My initial guess was to just take the transorms in chronological order to reconstruct the pose history. However, to my understanding, the published transform is for the current best particle. When a resampling occurs and the current best particle changes, the transforms published so far will become irrelevant. Is there any way to get around that, or am I misinterpreting the way that the gmapping package works? Thanks, Ivan Dryanovski
