Hello ROS-Community,

I am currently working my way through the MoveIt-GettingStarted Tutorial ( ). I do have installed Ubuntu 18.04 and ROS Melodic.

Everything works fine, until I try to add 'MotionPlanning' from the moveit_ros_visualization folder into my RViz. All Links appear at the same place and it seems like there are no Joints loading. I checked via rqt graph if my joint_state_publisher or my robot_state_publisher is not working. But regarding to rqt_graph both are actually working.

Any advice how I can fix that problem would be great. Thansk alot!

Can you check whether this is another manifestation of the issue described in (among others) #q272692?

Sadly it doesnt help me yet.

I get an output which says "No active joints or end effectors found for group 'hand'. Make sure that kinematics.yaml is loaded in this node's namespace."

But actually i dont know how to fix it.

That's not really related. Ignore it for now.

What is the output of echo $LC_NUMERIC?

The output of echo $LC_NUMERIC is en_US.UTF-8.

I did a mistake by not putting that to my .bashrc file. Now my joints work! Thanks a lot!

You can solve this with

export LC_NUMERIC="en_US.UTF-8"

It is because of this rviz bug:

+1 for taking the time to answer, but that is what I believe #q272692 already tells the OP.

You are right. But this was more intended as a TLDR, in case someone looks this up in future. Your answer is more of a question than an answer. And this is called ros answers, right? ;-)

Well tbh this question is a duplicate of #q272692 so should have been closed as such. So gracing it with more answers seems like something we'd not want to do.
