hector slam with xtion - workable?

Hi all,

I've been playing around with Hector SLAM, seems to be "starting" to work.

The map (when viewed in rviz) shows the current scan, however move the robot and the map doesn’t move or "jumps" to a completely different place. With I take to mean that the scan matcher fails

Also there are quite a few

lookupTransform /base_link to /laser_link timed out. Could not transform laser scan into base_frame

despite having a static transform set up

<node pkg="tf" type="static_transform_publisher" name="static_transform_publisher3" args="1 0 0 0 0 0 1 /base_link /laser_link 100"/>

However I've looked at similar posts (i.e. Hector Slam with kinect here I should give up on this and revert to getting gmapping working?

Thanks

Mark
