Empty textures folder problem with URDF to PROTO conversion about urdf2webots

[ad-daniel]

Hi, which version of the tool did you use? The latest from pip or master/develop from the repo?
Also, would it be possible to have access to the urdf/meshes so as to be able to reproduce the issue?

[ozangungortuhh]

Hi Daniel,
I directly cloned it from git so the latest master. pip3 list shows: urdf2webots 1.0.18
mesh files are from the universal_robot and robotiq repositories:
https://github.com/fmauch/universal_robot/tree/calibration_devel/ur_description
https://github.com/jr-robotics/robotiq

The URDF file is here:

<?xml version="1.0" ?>

    Base UR robot series xacro macro.

    NOTE: this is NOT a URDF. It cannot directly be loaded by consumers
    expecting a flattened '.urdf' file. See the top-level '.xacro' for that
    (but note: that .xacro must still be processed by the xacro command).

    For use in '.launch' files: use one of the 'load_urX.launch' convenience
    launch files.

    This file models the base kinematic chain of a UR robot, which then gets
    parameterised by various configuration files to convert it into a UR3(e),
    UR5(e), UR10(e) or UR16e.

    NOTE: the default kinematic parameters (ie: link lengths, frame locations,
    offets, etc) do not correspond to any particular robot. They are defaults
    only. There WILL be non-zero offsets between the Forward Kinematics results
    in TF (ie: robot_state_publisher) and the values reported by the Teach
    Pendant.

    For accurate (and robot-specific) transforms, the 'kinematics_parameters_file'
    parameter MUST point to a .yaml file containing the appropriate values for
    the targetted robot.

    If using the UniversalRobots/Universal_Robots_ROS_Driver, follow the steps
    described in the readme of that repository to extract the kinematic
    calibration from the controller and generate the required .yaml file.

    Main author of the migration to yaml configs: Ludovic Delval.
