ROS2 MoveIt - No Planning Library Loaded

nejo1017 · October 7, 2021, 1:40pm

Hello,
I try to control my UR10e with ROS2 foxy and MoveIt2 on Ubuntu 20.04.

I installed the Universal_Robots_ROS2_Driver and followed the Instructions to get it up on MoveIt (first without real hardware).

I did these commands: (as described on github)

ros2 launch ur_bringup ur_control.launch.py ur_type:=ur5e robot_ip:=yyy.yyy.yyy.yyy use_fake_hardware:=true launch_rviz:=false

ros2 launch ur_bringup ur_moveit.launch.py ur_type:=ur5e robot_ip:="xxx.xxx" use_fake_hardware:=true launch_rviz:=true

then RViz started and I could get the Robot Model appear.

But I can not any paths because my dropdown menus are empty, as shown here:

And I get the Error No Planning Library Loaded:

I also got this output in the terminal where I started Moveit/Rviz:

jo@myubuntu:~/workspace/ros_ur_driver$ ros2 launch ur_bringup ur_moveit.launch.py ur_type:=ur5e robot_ip:="xxx.xxx" use_fake_hardware:=true launch_rviz:=true

That doesn’t sound too good… Is there something wrong with you rmoveit installation? If you compiled moveit from source, it might be good to rebuild your workspace from scratch.

nejo1017 · October 11, 2021, 6:05pm

Thanks for your reply.
I rebuilt the workspace and because it didn’t work anyway, I re-installed my ubuntu but it still shows the same error…

Is it correct to git clone the driver with “-b foxy” as an argument? Because on Github it doesn’t say that the argument is needed but without it is not even possible to build.

kind regards

nejo1017 · October 11, 2021, 6:13pm

Are there any additional MoveIt Robot Models needed, which are not included when following the steps on this site GitHub - UniversalRobots/Universal_Robots_ROS2_Driver at foxy ?

mauch · October 12, 2021, 7:06am

Foxy and main branch have been diverging recently due to upstream developments.

I’ve just tested a minimal setup with

========= ros2_control_demos =========
## foxy...origin/foxy
========= Universal_Robots_Client_Library =========
## master...origin/master
========= Universal_Robots_ROS2_Driver =========
## foxy...origin/foxy
========= ur_msgs =========
## ros2...origin/ros2

and sudo apt install ros-foxy-moveit ros-foxy-ros2-control and this works as expected.

nejo1017 · October 12, 2021, 10:22am

Thanks again for your answer, I was hoping that the ros2-control was the problem, because I did not install ros-foxy-ros2-control seperately at first.

After I installed it, I rebuilt the Driver (github instructions) but it is still the same error…

My steps are:

Install Ubuntu 20.04 (apt update, upgrade etc…)
Install ros-foxy-desktop (Ubuntu (Debian) — ROS 2 Documentation: Foxy documentation)
sudo apt install ros-foxy-moveit ros-foxy-ros2-control
follow the github instructions for the Universal_Robot_ROS2_Driver (Getting Started + Using Moveit)

Do I miss something?

then I execute these both commands, each in a seperate Terminal (after sourcing the workspace):

ros2 launch ur_bringup ur_control.launch.py ur_type:=ur5e robot_ip:=yyy.yyy.yyy.yyy use_fake_hardware:=true launch_rviz:=false


ros2 launch ur_bringup ur_moveit.launch.py ur_type:=ur5e robot_ip:="xxx.xxx" use_fake_hardware:=true launch_rviz:=true

But I do not start the external_control URCap in between (as described on github in the foxy branch). Is it necessary to use hardware in this step or can I test it without first?

best regards

nejo1017 · October 12, 2021, 10:34am

by the way, my builds finish with no errors, and Rviz is starting. First without the robot model being displayed, but i can add it with the RobotModel and /robot_description. But I still get the same results as the pictures from my post are showing…

nejo1017 · October 12, 2021, 1:32pm

Thank you very much for your help!
It works now, since your commit!

best regards

hamzaadlane04 · October 30, 2021, 2:03pm

Hello,
I have also the same issue. I tried to modifed the bringup launch file for moveit but I still become the same problem. I have successfully install UR driver for foxy and also all moveit Packages.
I can open RVIZ with the launch file but I cannot see the robot.

It would be great if someone could help me

nejo1017 · November 2, 2021, 1:39pm

Hello,
it is actually a new problem, see this github issue:
