Problem with navigation through rviz
Hey everyone, I am trying to do the tutorial about navigation. I am able to create a map with gmapping. After that I would like the turtlebot to navigate with rviz and the 2D Nav Goal button. The problem is, it not working. When I start the amcl.demo and use roswtf I get following message:
Beginning tests of your ROS graph. These may take awhile...

I have no clue what to do... I am searching since few days. Can someone help me? I am using Hydro on Ubuntu 12.04
Greetings
You built a map with gmapping, didn't you. So, your turtlebot works normally with teleop. Your ssh works normally. Your problem is to be not able to navigate your turtlebot with rviz. Did you check my solution( http://answers.ros.org/question/139701/turtlebot2-doesnt-work-with-amcl_demolaunch/ )
Thanks for replying. I will try your information and tell you how it went. I am just once in the week working with the turtlebots, it might take some time, but I will let you know :)
