Revision history [back]

Hello Aradvindhan,

May I ask a few more questions, exploring Eric's suggestion:

Which laser scanner are you using? Can you actually see your laser scans in rviz in a simple setup? What frame are they published in (are you sure their frame is /laser?

When you run rosrun tf view_frames while your nodes are running, it generates a tf graph with the publishing frequencies of each transform. Have a look at the transform tree from your laser scanner (/laser) to the robot frame (/base_link), what are the publishing rates for these transforms?
