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.
