How to setup tf frame for /laser_scan msg to display in rviz
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/Tutori...
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!
