For an example of how to get running, I would suggest you look at a some examples of stage already running. �In particular the move_base_stage package is a good example see�https://code.ros.org/gf/project/wg-ros-pkg/scmsvn/?action=browse&path=/trunk/demos/move_base_stage/��

Hi everybody,

Perhaps somebody can give me a hint as I am having a problem with setting up the navigation stack using stage. I am getting a warning that says:

"[ WARN] 405.900000000: Waiting on transform from base_link to /map to become available before running costmap, tf error: Frame id /map does not exist!"

When I try to add a "Static Map" in rviz I received an erro message: "No transform from [map] to [/odom]".

I suppose this transform should be included in the broadcaster but I don't know exactly how to translate a "nav_msgs/Odometry" into a map frame (or it is map to odom?). Does anyone know how it should be transformed?

Thanks

R.
