I am trying to run the navigation stack with a map built with gmapping. I followed the navigation stack tutorial (the RobotSetup one). The ROS version is Groovy.

Then, after I run the navigation launch file (as indicated in the tutorial), the terminal repeatedly reports an error:

[ERROR] [1385493617.133940604]: Extrapolation Error: Unable to lookup transform, cache is empty, when looking up transform from frame [/odom] to frame [/map]

[ERROR] [1385493616.634300392]: Global Frame: /odom Plan Frame size 130: /map

[ WARN] [1385493616.634367789]: Could not transform the global plan to the frame of the controller

This is the entire output when the launch file is run:

bernardo@bernardo-Satellite-U400:~$ roslaunch robot socrob_nav.launch
