2 years ago I'm also facing the same issue! I have noticed that after following the steps mentioned in the tutorial, i did rostopic list. "/arm_controller" topics come up on the first time, but on re-running the rostopic list command, i have observed that amr_controller doesnt seem to be on the list. Something is causing the arm controller to stop and hence action client says not found. Please check for the same.

It looks like the newer versions of Unity mess up the rigged Unity UR10 model. You can try to re-import the UR10 URDF or wait for us to update.

Hello, thank you for your reply. To re-import the URDF i'll need to follow your "Import URDF" tutorial right? I shall let you know how this goes. Also, would this issue be resolved if we try this tutorial in your version of the editor, i.e 2020.1.1f1?

2 years ago Folllow the "LEO Robot" Example, except for UR10: https://github.com/fsstudio-team/ZeroSimROSUnity#import-urdf
Also, you may need to use a 2020 version of Unity as we have not done any thorough testing with 2021 and it seems to break a lot of things -- we are slowly working through the issues with 2021.

Okay, will try this out. Thank you! Also, yes. I am using Unity version 2020.3.33f1 LTS.

2 years ago FYI: Some random notes for UR10 Import from awhile ago -- should be still relevant. Note: the ZeroSim Docker image already has UR10 repo in the Catkin Worksapace.
Convert STL & DAE meshes to OBJ: /zerosim_tools/convert_meshes_to_obj.sh ./src/universal_robot/ur_description/meshes/ur10/
Generate UR10 URDF rosrun xacro xacro src/universal_robot/ur_description/urdf/ur10_robot.urdf.xacro transmission_hw_interface:=hardware_interface/PositionJointInterface > /tmp/ur10.urdf
Copy the generated URDF docker cp my_zerosim_vnc_docker:/tmp/ur10.urdf .
Copy the meshes: docker cp my_zerosim_vnc_docker:/catkin_ws/src/universal_robot/ur_description/meshes .
Fixup the mesh paths

2 years ago @tejasps28 after further analysis I may be sending you down the wrong rabbit hole. Apologies. I am now seeing some weird connection issue through ROS bridge. In the Unity console I'm getting:
ERROR: ZOROSBridgeConnection::ClientReadAsync System.InvalidOperationException: Queue empty.And in the Docker I'm getting:

Uh, yes. I had noticed these myself too. So could you suggest what's the right way forward? Also, i did try the aforementioned steps and it didn't seem to work. Got the same error.

2 years ago Not super clear on that at the moment. Trying to back track to what has changed to have caused this issue -- we haven't done a lot of changes in the past several months, either to the Unity code base or the Docker image -- so it is one of those very odd bugs.

Okay. Please let me know the solution to this when you find the bug. Thank you!

So RQT works just fine (see above). Something broken with the RViz config. Try launching RViz without the configuration and hand configure it?

commented
2 years ago I'm sure there is just some weird ROS namespace thing or some minor configuration with RViz MoveIt. Take a look at the launch file: /catkin_ws# vim src/zero_sim_ros/launch/ur10_moveit.launch. But it appears RQT and MoveIt! Python works just fine -- RViz I don't have an ETA on fixing this.

2 years ago @micahpearlman Thanks, i did this and was able to reproduce the same using RQT. Willl try rviz configuration manually and let you know how it goes.

2 years ago @micahpearlman @tejasps28 Hi, I have found the problem. Just correct the ZO_CONTROLLER_MANAGER_SERVICE in Unity Editor with name undefined_10 -> ur_10_control. It will work. Please correct and commit.
I have verified it with docker and VNC. I will try to test it on noetic as well.

Hi,
I am trying to run UR10 with moveit as per the instructions. However, Moveit is not able to connect with Unity and it says
I have tried multiple options with sim param, as its should remap /follow_joint_trajectory to /arm_controller/follow_joint_trajectory, but it is not able to do it. Has anybody faced the same issue ?
Detailed terminal goes:
