Hi Andreas,

just make the two lasers publish to the same topic. Amcl will notice 
that there are laser messages in different frames and will query tf for 
the transformations between base_link and and these frames.

You may need two static_transform_publisher nodes so amcl can get this 
information.

Cheers,
Ingo
