-===== Reading information from external sources ===== 
-Examples for loading information from external sources, like other ROS nodes, are given in the following packages: 
-  * comp_cop for reading information from the CoP perception system 
-  * tf_prolog reads coordinate transformations from tf 
- 
-Depending on the kind of information to be included, these interfaces need to be adapted, but the general principle should stay the same.
