Dan,

The wavefront package has fallen into a bit of disrepair as we favor our move_base package for autonomous navigation. If you're looking to run some autonomous navigation demos, check out the move_base_stage package instead of the 2dnav_stage package. The 2dnav_stage package will probably be removed in the near future to save people the confusion.

Hope this helps,

Eitan

Hi all - I'm having some trouble using wavefront. When I try to start it I get this:
robotics@tears$ rosrun wavefront wavefront
terminate called after throwing an instance of 'ros::InvalidNameException'
  what():  Using ~ names with NodeHandle methods is not allowed.  If you want to use private names with the NodeHandle interface, construct a NodeHandle using a private name as its namespace.  e.g. ros::NodeHandle nh("~");  nh.getParam("my_private_name"); (name = [~dist_eps])
/home/robotics/ros/ros/bin/rosrun: line 35: 15562 Aborted                 $exepath "$@"
Granted, I don't know what the right way to use wavefront since the documentation is a bit spotty.

Any ideas would be appreciated.

Thanks,
