[ros-users] wavefront

[Dan Lazewatsky]

Thanks for the response Eitan -
I've created a map, and am trying to get an erratic to navigate in said 
map using nav_view. I set up the robot according the the nav robot setup 
tutorial, and when I run nav view I can see the map and set the robot's 
initial pose, but trying to set the goal doesn't seem to do anything. I 
get a printout from nav view saying "setting goal: Position(...)" but 
that's all.
