For number 4, you probably do not have the correct frame specified for either global_frame or robot_base_frame in your global_costmap_params.yaml(see <a href="http://www.ros.org/wiki/navigation/Tutorials/RobotSetup#Costmap_Configuration_.28local_costmap.29_.26_.28global_costmap.29">http://www.ros.org/wiki/navigation/Tutorials/RobotSetup#Costmap_Configuration_.28local_costmap.29_.26_.28global_costmap.29</a>).  For ours we used this: <a href="http://github.com/wjwwood/au-automow/blob/master/au_automow_common/2dnav_automow/global_costmap_params.yaml">http://github.com/wjwwood/au-automow/blob/master/au_automow_common/2dnav_automow/global_costmap_params.yaml</a>.  I say this because I believe I ran into the same problem when we were first setting up the navigation stuff.<div>

<span style="font-family:Tahoma;font-size:10pt">Hello all,<br>
I would like to know some basic difference between stage and rviz through following questions:-<br>
1. If we my navigation stack is set so as to visualize and simulate then Can we replace stage by rviz ? <br>
2. Can we have amcl, map, costmap2d - Global and Local and planner algorithms in place and see robot reactions in rviz?<br>
3. Can we totally eliminate stage from use?<br>
4. Also, i tried to load a static map in rviz. The initial grid is horizontally set in orbit view properly and map is getting loaded somewhere vertically which i am not able to move and see it properly. I am doing something wrong?<br>


thanks,<br>
