Thanks for your so detail reply! Please let me ask some other question as following: 1. if the map haven't been saved when the slam is running, and the robot will lose the position of itself when rebooted, is it right?

1. if the map is saved when the slam is running , and after the robot reboot with slam, the saved map will be refreshed by slam?

2. one basic function of slam is location, when the robot run without saved map, how the robot locate the position of itself without map?

2. if the map is saved when the slam is running , and after the robot reboot again with slam, the saved map will be refreshed by slam?

   I think the saved map woking as static global map , and after the robot reboot again with slam, the new map built by slam is working as local map ? (local map also has severl layers such as static layer, obstcle layer, and so on. which map and which layer does the new map built by slam works in ?)
