No description provided.

The action client should be able to select a behaviour, i.e., either 'wait-for-person', or 'wandering' (parameter name: 'search-for-person'). Both behaviours are exclusive. The 'wait-for-person' behaviour gets an initial pose where the robot waits for a person. If it finds a person it follows the person (within the specified following ROI). If it looses the person the robot goes back to its initial pose.
