Hi Nitin, The TF_OLD data message, as Tully pointed out, was due to tf not being robust to time skips the workaround is to restart the complaining node. periodic_snapshotter doesn't really work with the provided bag file, however, the pr2_laser_snapshotter will work fine if you record a topic of the type pr2_msgs/LaserScannerSignal. -Hai On Tue, Aug 3, 2010 at 6:55 AM, nitinDhiman wrote: > > Hi Hai and Tully, > > I am also facing same problem.
