Are you actually running move_base?

Hello Dornhege,
I publish these messages:
/odom
Type: geometry_msgs/TwistStamped
Publishers: * /vrep (http://ubuntu:39530/) Subscribers: None
/odom_2
Type: geometry_msgs/PoseStamped
Publishers: * /vrep (http://ubuntu:39530/)
Subscribers: None
/rosout
/rosout_agg
/tf
/vrep/info
/vrep/laser_scan
from V-rep to ROS. But after running the executable: simple_navigation_goalsI always have: Waiting for the move_base action server to come up. Can u please tell me what more I should publish/subscribe?

It seems like you're not running move_base. You need to run the move_base node as that supplies all the navigation functionality.

The move_base node which is in http://wiki.ros.org/move_base?action=AttachFile&do=view&target=overview_tf.png defined? I'm running a simulation in rviz. How shall I support that? I thought I shall publish each necessary msg to ROS. Can u please help me with that?

In ceneral I have these now:
rostopic list /move_base/cancel ,/move_base/feedback ,/move_base/goal ,/move_base/result ,/move_base/status ,/odom ,/odom_2 ,/rosout ,/rosout_agg ,/tf ,/vrep/info ,/vrep/laser_scan

Are you trying to emulate move_base by offering the same topics or are these from running move_base?
Asked by dornhege on 2013-09-18 01:19:25 UTC
That's what im doing: I wanna send a very simple command from the simple_navigation_goals package (wiki.ros.org/navigation/Tutorials/SendingSimpleGoals) to a simulated kuka youbot in v-rep. I added some lines to the script of the simulated robot to support topics necessary for move_base action server.

In that case, you'll need to implement an action server for the MoveBaseAction: http://wiki.ros.org/move_base_msgs?distro=hydro
