How to determine the world coordinate of a cell to update its cost in a costmap?
I'm trying to follow the tutorial example for Simple Layer here: http://wiki.ros.org/costmap_2d/Tutori...
I'm trying to set the cell whose cost will be update 2 meters in front of the robot for example, instead of 1 meter as shown in the tutorial.
However, nothing seems to change the location of the updated cell. I've tried changing the value for mark_x_ & mark_y_, I changed mx & my, I've even commented out the entire code section in updateCost but that doesn't seem to have any effect either as the modified cell is still visible, which is exactly 1 meter in the x direction.
How do I determine which cells I wanna modify and to input the correct coordinates of the cells?
It might be worth noting that I'm running the costmap node independent of the navigation stack.
