Not seeing Kinova robot in Rviz when following tutorial

[dsandber]

Description

I'm following the tutorial here:

https://moveit.picknik.ai/main/doc/tutorials/quickstart_in_rviz/quickstart_in_rviz_tutorial.html

When doing: ros2 launch moveit2_tutorials demo.launch.py

rviz came up, and the "MotionPlanning" extension was already added even though the tutorial says I need to add it. However, the robot from the tutorial didn't show up. I tried removing MotionPlanning and adding it again but the robot still didn't show up. I've included the program output.

Your environment

• ROS Distro: Iron
• OS Version: Ubuntu 22.04.3
• The ROS was a binary build, for MoveIt I followed the instructions here: https://moveit.picknik.ai/main/doc/tutorials/getting_started

Backtrace or Console output

log.txt

Update: When following the docker instructions rviz brought up the robot (ie, that worked fine)

Do you use a locale, that has comma as a decimal point? Then try this:

LC_NUMERIC=en_US.UTF-8 ros2 launch moveit2_tutorials demo.launch.py

Sadly this is know, but not mentioned in the tutorial.

[dsandber]

Yup, thanks, that fixed it! Should I submit a patch to the setup page to include this?

[MRQ]

I would be happy if you work to get this in the tutorial.

Either this is a recurring bug, or nothing improved within he last year: moveit/moveit2_tutorials#508

I just assigned @tylerjw because the issue linked above had tagged him before moveit/moveit2_tutorials#508 (comment) and he's familiar with the params

We have tracked and supposedly fixed this issue before: #1882

[dsandber]

I looked for the part of the documentation that listed a bunch of environment variables to set, but I couldn't find it even though I remember following it. Should I suggest a change to the ros.bash that you're supposed to source? Or just leave this to others to fix at the source (code that is making assumptions)?

[github-actions]

This issue is being labeled as stale because it has been open 45 days with no activity. It will be automatically closed after another 45 days without follow-ups.

[henningkayser]

I'm closing this since ROS documentation recommends setting locale support to en_US.UTF-8. We are still tracking the very same problem in #1882, so feel free to follow up or contribute from there.
