Hello all,
I would like to know some basic difference between stage and rviz through 
following questions:-
1. If we my navigation stack is set so as to visualize and simulate then 
Can we replace stage by rviz ? 
2. Can we have amcl, map, costmap2d - Global and Local and planner 
algorithms in place and see robot reactions in rviz?
3. Can we totally eliminate stage from use?
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?
thanks,
