no robot visible in rviz for urdf tutorial
I'm working my way through the urdf tutorials, specifically this one
On the first task it has me launch rviz to see the "r2d2" robot using the command: roslaunch urdf_tutorial display.launch model:=01-myfirst.urdf
I am in the proper directory, rviz launches just fine, but there is no robot visible. Just the grid map. This error appears under the Global Status in orange: No tf data. Actual error: Fixed Frame [map] does not exist
So I get that it's not getting transform data, but I'm not sure what to do about it. I have not modified any files, am running hydro on Precise.
