error happens while using addArticulatedSystem

[wzjscut]

When I use the CPP API world.addArticulatedSystem("XXX.urdf"); it shows the error log below:

terminate called after throwing an instance of 'std::invalid_argument' what(): stoi Aborted (core dumped)

and the URDF file: https://drive.google.com/file/d/17ajNF_3T2UKmNvxqySPYllH63wv2_Ptn/view?usp=drive_link

I cannot access that file. Did you test that urdf with other software?

Hi prof. hwangbo,

Sorry for setting the error access. I have updated.

I also test the urdf through urdf-viz and check_urdf and it shows the robot correctly check_urdf shows the logs below
