Commands for navigation [closed]

edit

Hi, I followed this tutorial http://wiki.ros.org/navigation/Tutori... but I positioned .yaml file in catkin_ws/src/navigation/navigation, move_base.launch file in catkin_ws/src/navigation/move_base/launch and robot.launch file in catkin_ws/src/navigation/costmap_2d/launch. Then I type:

roscore
rosrun xv_11_laser_driver neato_laser_publisher _port:=/dev/ttyUSB0 _firmware_version:=2
rosrun tf static_transform_publisher x y z yaw pitch roll frame_id child_frame_id period_in_ms
rosrun map_server map_server
rosrun move_base move_base
roslaunch costmap_2d robot.launch
roslaunch move_base move_base.launch

I want to know if the commands are correct or if something is missing, for example if I have to throw my launch file with which I do the mapping. I would also like to know how can I make sure everything is working properly: what should appear on the map? This also equates to exploration? Thank you.
