Hi,

I try to build a map in Rviz using turtlebot simulation in gazebo. First I create a package and write a launch file which open GAZEBO world and turtlebot in that environment ...

That is the Launch file

<launch>


 <node name="gazebo" pkg="gazebo" type="gazebo" args="-u $(find gazebo_worlds)/worlds/simple_office.world"/>

 <param name="/use_sim_time" value="true"/>

 <node name="gazebo_gui" pkg="gazebo" type="gui"/>

 <include file="$(find turtlebot_gazebo)/launch/robot.launch"/>

 <include file="$(find turtlebot_teleop)/keyboard_teleop.launch"/>

</launch>

Then I run rosrun gmapping slam_gmapping scan:=base_scan _odom_frame:=odom_combined

Then open Rviz with rosrun rviz rviz -d 'rospack find turtlebot_navigation' /nav_rviz.vcg , this command does not open plugins required for gmapping as it can not locate nav_rviz.vcg, so finally I open rviz from launch file

<launch>

 <node pkg="rviz" type="rviz" name="$(anon rviz)" args="-d $(find turtlebot_navigation)/nav_rviz.vcg">  </node>

</launch>

It work well at lest it run all requirements for gmapping ....

The problem now that when I move robot in gazebo, robot move in rviz too but does not make a map, and I find that massage in rviz : Message No map received

Edit I write this command

amal@amal-HP-G62-Notebook-PC:~$ rosrun gmapping slam_gmapping scan:=base_scan _odom_frame:=odom_combined

and nothing else in is written in terminal see warning

All nodes that run and topics

Edit2 That is the map but I think it will not accurate if there is more details in the environment and It seems to be footprints !!

Edit3

Can you check if there is laser data?

how to do this ?!

The simplest way would be an rviz display.

Remove the remapping of scan to base_scan. You are publishing the laser on /scan, so no remapping is needed.
