I could only locate the URDF files for version 0.3.0 (e.g., xlerobot.urdf, xlerobot_front.urdf) in the repository. There does not appear to be a URDF for the latest robot model (version 0.4.0).
Could you please confirm whether the URDF for v0.4.0 is available, or provide/upload the new version if it is missing? Thank you.
