gmapping error

[Salocin Remmeth]

Hi!

I followed instructions from this site:

http://learn.turtlebot.com/

to set up my turtlebot. Everything seems to work just fine but I am having problems launching gmapping when trying to run this command on turtlebot laptop:

roslaunch turtlebot_navigation gmapping_demo.launch

I am getting following output:

The error runs in a loop. I followed the instructions here http://answers.ros.org/question/210849/scan-message-must-contain-angles-from-x-to-x/?answer=213890#post-id-213890 to solve this issue but it still doesnt work. Maybe because they are using gazebo. I'm running out of ideas :/

Thanks in advance!
