I have setup my laser properly, able to display a topic called laser_scan,
However when i display it on rviz, there was no visual display, despite having receiving messages and with no error received.
I have tried tuning the size and display still was not found. I figured that my tf frame may be set up wrongly.
Can i clarify that i just have to follow the steps as like the tutorial in the link?
http://wiki.ros.org/navigation/Tutorials/RobotSetup/TF
If so, is there any line of codes that I have to change to fit my case?
And theres TF Publisher and TF Listener which i get confuse of how they work.
Is it i put in the TF Listener in my laser code? Or do i just put tf publisher and listener in the same package file.
Thanks a lot!
