Hi everyone,
When I want to run the move_base as the action server for the test code in:
http://www.ros.org/wiki/navigation/Tutorials/SendingSimpleGoals
The launch file of the move_base is:
> <launch>
>
> <param name="global_costmap/robot_base_frame" value="/robot_base"/>
> <param name="global_costmap/global_fram" value="/world"/>
> <node name="move_base" pkg="move_base" type="move_base" respawn="true">
> </node>
>
> </launch>
>
It keeps popping up the message in rxconsole:
Node: /move_base
Time: 1273663641.651775000
Severity: Warn
Location:
/home/ming/ros/stacks/navigation/costmap_2d/src/costmap_2d_ros.cpp:Costmap2DROS::Costmap2DROS:86
Published Topics: /rosout, /cmd_vel, /move_base/current_goal,
/move_base/goal
Waiting on transform from /robot_base to /map to become available before
running costmap, tf error: Frame id /map does not exist!
Which package defines /map should be the global_frame?
Does anybody have a clue how to fix the problem?
Thanks very much!
Best regards,
Ming
