Hi, when i am setting up a navigation stack for my pioneer robot but when i am running move_base.launch after receiving a static map from map_server its writing below warning: "Waiting on transform from /base_footprint to /map to become available before running costmap , tf error."

currently my tf_tree is something like this:

odom_combined---> base_footprint ----> base_laser

Do you have amcl or gmapping running? When using a static map published by the map server, you need to run amcl. It will localize your robot in the map and publish the transform from map to odom_combined.

AMCL will run with move_base.launch !

If you checked that amcl is running (e.g. with rosnode list) it doesn't get the data it requires, i.e. either the odom topic or laser scans are not coming in. Please don't answer in a new question but either edit your question or post a comment. This is not a forum.
