I created a grid map using a turtlebot and after I wanted to navigate in that map I used the navigation stack Amcl but after I run it using the turtlebot navigation package I am getting this errors in transformations could someone tell me what is wrong here ?

I am using ros kinetic and I do have a real turtlebot

It is solved the problem was with the laser scanner. I am converting 3d points cloud to laserscanner and I forget to remap the topic but now it is working well. Thanks

I was using the navigation package for turtlebot. The problem is the package launches all the lasserscanner and the cameras as subscribes automatically. But for me I was using my own laserscanner topic that I got from merging three projected 3D point clouds and it has different name of the standard /scan topic. I just remapped my scan topic to /scan and it worked.
