Zhiping,
Could you please ask this question on http://answers.ros.org
We're transitioning troubleshooting questions to that website to
decrease the volume on this mailing list and make past questions more
visible. https://code.ros.org/lurker/message/20110216.014950.2c9cb33e.en.html
Thanks,

Zhiping,
Hi to all,
I'm currently trying to load an empty map by directly publishing it in the
form of nav_msgs/OccupancyGrid instead of using the map_server.Could you elaborate on why you want to load an empty map instead of simply not initializing anything with a static map?Knowing amcl
is combining all the 'tf' together, what should i do to pass the odom-to-map
tf to amcl.AMCL is not "combining all the tf together" in any filtering sense - it is actually generating the odom->map transform! Hence, you do not need to feed an odom-to-map transform into amcl. In fact, an odom-to-map transform would be unnecessary if you don't have a map. In that case, there is no need to run amcl at all.If you want to build a map on the fly, you should look at the gmapping package (http://www.ros.org/wiki/gmapping).- Eric
With thanks,
Zhiping
