you also need to record the laser_scanner_signal topic that your pr2
laser tilt controller publishes. Just tf and the laser topic are not
enough since the snapshotter needs to know when a full tilt scan
finished to assemble the cloud.


> Hi,
> Is it possible to use pr2_laser_snapshotter package offline, i.e. on the bag file from the PR2 which has laser scans and TF messages? I tried to use it, the same way I would use it on the robot, but it is not working. There are no error messages, it's just that RViz is not getting any pointclouds, as if the publishing and subscribing between the nodes is not done properly.
> Am I doing something wrong or is this package only working on the PR2 directly?
