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?
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
