How does rviz display estimated pose from AMCL
Hi, I am working on AMCL recently. I wonder how does rviz receive estimated pose from amcl node and display it on map? I found that there are no nodes subscribe amcl_pose topic when robot moves, so how does the amcl_pose topic work? Thanks.
rviz also publishes the tf from the odom frame to the map frame which is basically the same information on on a different topic.
