Hello ROS users ^^ I am using MoveIt Tutorial. (https://ros-planning.github.io/moveit_tutorials/doc/quickstart_in_rviz/quickstart_in_rviz_tutorial.html) When I am launching my RViz with (roslaunch pandamoveitconfig demo.launch rviztutorial:=true), I see an empty world. Until now, everything works well here. But my problem is here!!! When I add MotionPlaning to my Display window, my panda robot arm is stick together and doesn't look like a normal arm! (I have attached screenshots about my arm and a normal arm!). I also used MoveIt Setup Assistant and created my own configurations, (https://ros-planning.github.io/moveittutorials/doc/setupassistant/setupassistant_tutorial.html), but still doesn't work!

Can you help me????!

I am using Ubuntu 18.04 LTS and ROS Melodic.

Here is a screenshot of robot. Please look at it here ---(https://drive.google.com/file/d/1yjzGr-QAcJ5wz8ka-g9enFFmKXiuT/view?usp=sharing)

My robot arm should look like this, but it is not!
