hello, I am working in a simulation environment in vrep and by publishing base_scan to gmapping in ros i am creating a map, Now i want to do navigation on map which is creating by gmapping not on a static map by download in pgm or yaml format, i want to do navigation on runtime generating map by gmapping. Please help me what can i do now for navigation and path planning, i have seen a links on move_base node but cant link with my gmapping map which are creating in rviz and model not going to goal, please help me fully, i shall be very thankfull to you.

Procedure till now: 1)run roscore 2)catkin_make 3)devel/source bash.setup 4)run vrep and open and start vrep model and publish topics of laser scanner,odom and tf. 5)on new termial rosrun tf static_transform_publisher 0.2 0.0 0.1 0.0 0.0 0.0 base_link base_scan 50 6)on new terminal rosrun gmapping slam_gmapping scan:=base_scan 7)open rviz 8)on new terminal roslaunch gmapping mapping.launch model starts mapping on rviz

so please can u tell what is the solution for this?

i get the following error while i run the launch file with

roslaunch youbot_navigation_local move_base_local.launch

Sir my simulator publishes the /tf frame of my robot.now if i remove all the nodes from launch file including tf also. Then what i do now next for navigation stack and to run+link the navigation code that i got from github?

I was looking at robotsetup tutorial. ( http://wiki.ros.org/navigation/Tutori... ). In section 2.2 Creating a Robot Configuration Launch File in which i have to Replace "sensor_node_pkg" with the name of the package for the ROS driver for your sensor, "sensor_node_type" with the type of the driver for your sensor, "sensor_node_name" with the desired name for your sensor node, and "sensor_param" with any parameters that your node might take. and also replace all things for odometry and tf.

I don get what are these values?

Actually i am working with vrep and ros and till now i have done with gmapping by getting the /base_scan /tf values from the vrep simulation and create the map in RVIZ, and downloaded the map.pgm by rviz but now i dont know how to set the navigation stack.

but next i am stuck at navigation what i do. i have downloaded all the files from git hub attached below related to navigation stack.

https://github.com/ros-planning/navig...

please let me know how to run this code which command can be use to run this code that i got from github. and what changes i have to do please tell me what should now i can do?

Please help me i shall be very grateful to you.

Hello friend could u please help me out that after generating map with gmapping in rviz how can i do path planning. I have download the map.pgm from rviz but now i dont get how start path planning and how to link with map. Please help me.

Thanks
