Hi all,

I am new in ROS!

I am trying to do tutorial in: http://www.ros.org/wiki/turtlebot_navigation/Tutorials/Build%20a%20map%20with%20SLAM

I want to rum navigation of thww turtlebot, only, in simulation environment Gazebo, so This what I did:

FIRST: in terminal 1, I imports with wg_world: roslaunch simulator_gazebo wg_world.launch


SECOND: in terminal 2,I bring turtelbot robot in this simulation environent: roslaunch turtlebot_simulator robot.launch


THIRD: in terminal 3,I laumch gmapping demo: roslaunch turtlebot_navigation gmapping_demo.launch

ERROR: . . . [kinect_laser-5] process has died [pid 16382, exit code 255]. log files: /home/bkhelifa/.ros/log/7cf0b598-683a-11e1-b3b1-b870f4a01c9f/kinect_laser-5.log respawning... [slam_gmapping-7] process has died [pid 16061, exit code -6]. log files: /home/bkhelifa/.ros/log/7cf0b598-683a-11e1-b3b1-b870f4a01c9f/slam_gmapping-7.log [kinect_laser-5] restarting process process[kinect_laser-5]: started with pid [16467] [kinect_laser_narrow-6] process has died [pid 16443, exit code 255]. log files: /home/bkhelifa/.ros/log/7cf0b598-683a-11e1-b3b1-b870f4a01c9f/kinect_laser_narrow-6*.log respawning... . . .

BY REMOVING Kinect line from the FILE I GOT:

. . . [slam_gmapping-1] process has died [pid 7572, exit code -6]. log files: /home/bkhelifa/.ros/log/7cf0b598-683a-11e1-b3b1-b870f4a01c9f/slam_gmapping-1*.log . . .

FORTH: Run rviz as showed in tutorial: rosrun rviz rviz -d rospack find turtlebot_vigation/nav_rviz.vcg

Thank you in advance

...what do you mean "It's not working?" We're going to need details.

All the error messages list log files. What's the content of those?

thx, but I could not read the log file (cat /home/bkhelifa/.ros/log/e2b8d972-6908-11e1-9ea6-b870f4a01c9f/slam_gmapping-1*.log) giving: no such file or directory

Replace the * with anything you can find.

This what I found there is no slam_gmapping.log diagnostic_aggregator-4-stdout.log kinect_laser-7-stdout.log kinect_laser_narrow-8-stdout.log master.log robot_pose_ekf-6-stdout.log roslaunch-bkhelifa-Aspire-5755G-1897.log roslaunch-bkhelifa-Aspire-5755G-31367.log roslaunch-bkhelifa-Aspire-5755G-73

I am not sure if it is an error, but I have never found the log files that roslaunch mentions...
