I followed [this](https://www.youtube.com/watch?reload=9&v=j6bBxfD_bYs) Youtube-tutorial, but I end up not being able to execute any movements, planning works fine so far.
These are the errors I get when my Robot is launched in Rviz.
Planning scene monitors started.

When I use rostopic list in a seperate shell when launching the above file, I can see the arm_controller, but once everything settled launching the above file, the arm_controller is no more shown on rostopic list and several other topics are then displayed.
Now this is the error I eventually get when trying to execute a planned path:

I have checked several files like
Appreciate your help! Thanks!
