No tf data. Actual error: Fixed Frame [world] does not exist about gazebo_ros_demos

Could probably be closed either.

What? I don't understand your response.

Oh yeah, sorry, it was a bit quick.

I have installed recently ROS Indigo and Gazebo from scratch and had no issue with the tutorial that you mention. As you have closed the issue #8 which was related to the installation of the simulator, I guessed that this one could also be closed.

Just a guess, it could totally be wrong.

Issue #8 was a different problem in a different section of the tutorial. I'm now running a fresh install of Indigo+Gazebo 2 on Ubuntu 14.04, which is the recommended setup and I'm getting a different error. The tutorial seems to be missing several steps, and a lot of the code it shows doesn't match what's in gazebo_ros_demos, so I'm not sure if I'm following the correct instructions.

Am I launching the components correctly? What would be causing the fixed frame error? Should the RViz 3d view show the same thing as Gazebo?

I had to install the packages for the controllers:

sudo apt-get install ros-indigo-effort-controllers
sudo apt-get install ros-indigo-joint-state-controller

I have used RQT to control the RRBot and not the command lines:

rosrun rqt_gui rqt_gui

What are your errors?
