Hi,
I've searched and i found similar questions, but no conclusions.
scenario:
ROS: Indigo
Laser: XV11
The robot is stable not moving, i move near the robot, and the map is updated with an obstacle, i move away, and the obstacle is not removed (unless the move_base is restarted), the laser is clear, the obstacle is still there plus some yellow dots.
rviz snapshots:
initial: https://dl.dropboxusercontent.com/u/17246489/PIC0.png
obstacle present: https://dl.dropboxusercontent.com/u/17246489/PIC1-NEWOBSTACLE.png
obstacle gone: https://dl.dropboxusercontent.com/u/17246489/PIC2-OBSTACLE-GONE.png
obstacle gone (laser only): https://dl.dropboxusercontent.com/u/17246489/PIC3-OBSTACLE-GONE-LASERONLY.png
If i go again to the front of the robot the obstacle area get's bigger, and stays there even when i move away.
Any clues ?
Regards,
Tiago

We can't help without seeing your configuration files. please post the parameters for move base.

@David: Thanks for asking, I've updated the post.

I'm unclear what your third picture is showing. What does the costmap look like after you move away?

@David: I updated the screenshots
