Hi,

I'm trying to set up gampping at the moment as a precursor to navigation. From looking at this forum it looks like this is a common issue ;-/ I've not figured out where I've gone wrong yet - hence my asking

Example output: rosrun gmapping slam_gmapping scan:=scan

I can't seem to get "ros.gmapping.messagenotifier" to show up in rqtconsole to figure out what's going on here. I think my tf tree is correct (image below from rosrun tf view_frames

This is rqt_console Screenshot from 2015-04-16 01:56:12.png

These two make up the important bits of the tf tree

and lastly my graph

Not sure if I need to change the transform some where. Any help much appreciated.

Thanks
