using als_ros when no known map and slamer mode

[altineller]

Hello,

I have been practising als_ros in simulation environment. It has been working very nice.

Do we have to have a map when using als_ros? Is it possible to use it when there is no map file?

And also, what is slamer mode and how can we use it?

Best Regards.
C.

As I know from their article, map is used just for recognition of the environment, also in slamer.launch there is not any command or sth to save map file, when I tried out its launch I used map_sever but actually I couldn't observe anything baout thi launch, mcl looks fine.
