OK, this should be published as 'comment', but i can't acess the commenting tool. Not enought 'Karma* Ok, still want to share you my similar experiences.
My turtlebot have the same problem with the 'set estimate pose' command in RVIZ. I get the pose and robot model nicely published and displayed in RVIZ, but i can't set the initial pose, or any navigation goal. My setup sometimes work, sometimes dont.
The system seems to work on a fresh 'just made map'. trying the day after is more unstable...
Everything else displays nice on RVIZ, if i manually pushes or rotates the turtlebot, RVIZ updates the movement and add all the red arrow just as if it was working. I just cant set the pose estimate or the 2D nav goal.
A difference from your tutorials is that i'm not adressing the by 'DNS name' such as turtlebot@marvin, instead i adresse as described in another tutorial by turtlebot@192.168.1.100
I use a dedicated WLAN with only the turtlebot and a remote computer, same IP:s from day to day. I have checked the network settings as suggested in a similar question http://answers.ros.org/question/2351/amcl-in-the-bottom-right-cornerforever
Is it likely that this is still an network error ?
What about the 'ticket,https://code.ros.org/trac/ros-pkg/ticket/5148 is this in progress?
Any workaround ? is upgrading to 'electric' a way forward ?
Thank you
