Hello everyone
I was using ROS hydro, however I updated Ubuntu and installed ROS indigo in my computer. I am writing to you because I am currently trying to make a robot which goes from an estimated point to an aim point, for this I need to use tf (to find the robots estimated position), but when I execute my program the following warnings appear
warn: worldfile /home/diego/MobileRobots/src/AIS_worlds/LBH_floor_1.world:43 : property [interval_real] is defined but not used (/tmp/buildd/ros-indigo-stage-4.1.1-2trusty-20141229-2215/libstage/worldfile.cc WarnUnused)

I can cope with this if this it's just a simple problem or something with no importance (the map is loading perfectly), however the warning of TF_OLD_DATA is appearing at every 0.1s, Additionally I suspect that the robot is not receiving estimated position correctly:

And finally, the robot does not stop when it has to.
Can anyone please help me with this?
