You can find it by doing the following at the command line: find /opt/ros/indigo -name turtlebot_node.py in my case it returns /opt/ros/indigo/lib/create_node/turtlebot_node.py

I have the same problem and I am trying to apply the fix you propose but apparently my turtlebot_node.py is different, so I cannot. Could you post the entire file here so that I can compare the 2 in more detail?

2015-10-06 18:31:46 -0500	asked a question	Create Turtlebot Joint State in Indigo is always 0 I'm using a Turtlebot with the Create base in Indigo and I'd like to read out the wheel encoder rotation values. Using Gazebo this is published as an array of positions in /joint_states but on the robot itself the messages always have 0 values for positions (and the other arrays as well). This problem has been reported for Hydro here, but I cannot reproduce the fix in Indigo. What can I do to have /joint_states give me the correct info, or alternatively get these values from somewhere else?
