Import Robot from URDF stays greyed out

[snowgoon88]

Describe the bug
I followed the "pick_and_place" tutorial and when trying to import the nyrio_one.urdf file by right-clicking, the "Import Robot from URDF" option stays grey. No possibility to import the URDF.

Console logs / stack traces
the only message in the console are warnings

Script 'Joint' has the same name as built-in Unity component.
AddComponent and GetComponent will not work with this script.

Assembly for Assembly Definition File 'Assets/RosMessages/Unity.Robotics.RosMessages.asmdef' will not be compiled, because it has no scripts associated with it.
UnityEditor.Scripting.ScriptCompilation.EditorCompilationInterface:CompileScriptsNoStop (UnityEditor.Scripting.ScriptCompilation.EditorScriptCompilationOptions,UnityEditor.BuildTargetGroup,UnityEditor.BuildTarget,string[]) (at /home/bokken/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/EditorCompilationInterface.cs:306)

Screenshots
file is selected, right click on it

I know this is old, but I was able to solve this problem by moving my Unity PickAndPlaceProject folder to my base C:\ directory. The file path inside the Unity-Robotics-Hub repo is too long for Windows and causes some sort of error. Make sure you delete your Library sub-folder after you move the main project folder.

hello, I got the same issue earlier today and it turns out the real niryo_one is the one under niryo_one folder and without the "_urdf". From there, you should be able to import it using URDF.
