[ros-users] strange lagging behavior in rviz, in the links connected to the base_link

[Stuart Glaser]

Hi Kadir,

Next time you see this problem try running tf_moniter:

rosrun tf tf_monitor

It should help you debug delays between frames.  Like Josh said, it's
likely you'll find that the frames from a particular computer are
delayed because that computers clock is running slow.
