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 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?

Are you trying to emulate move_base by offering the same topics or are these from running move_base?

That's what im doing: I wanna send a very simple command from the simple_navigation_goals package ( 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:
