when the obstacle layer mark a cell as a lethal cell in the master layer, does it keep updating this cell as occupied until it is cleared by clearing observation ? Or it is only updated one time when it is detected by laser scanner ?
Yes, it remains until something tells it to be cleared either by raycasting or via an explicit costmap clear
It remains marked in the master costmap as occupied, yes.
Hi Steve, I appreciate your reply. But I think my question is misunderstood. To be clear, I created a layer that clears robot footprints in a multi-robot system, but the lethal cells come back after they are cleared, even if they are no longer detected by the laser scan. It's as if these cells are somehow continuously marked by the obstacle layer until they are cleared by the obstacle layer itself.
