I get the following error when using this project with ROS Melodic

Deprecated: xacro tag 'sick_lms1xx_mount' w/o 'xacro:' xml namespace prefix (will be forbidden in Noetic)

Use the following command to fix incorrect tag usage:

I solved this issue removing these two lines from the following file:
custom_description.urdf.xacro

<xacro:include filename="$(find husky_description)/urdf/husky.urdf.xacro" /> <xacro:husky_robot />

Hi sir
I put my husky_custom_description package in a ros work space named simulation_ws. Followed the suggestion in empty.urdf as "if a robot is being customized and requires additional URDF, set the HUSKY_URDF_EXTRAS environment variable to the full path of the file you would like included", I thus set the env variable using "export HUSKY_URDF_EXTRAS=$(rospack find husky_custom_description)/urdf/custom_description.urdf.xacro" in ~/.bashrc. However, I get some errors when I roslaunch husky_viz view_model.launch. I dont make sure what i have done is in a right way.

Hi.

Are there any instructions on how to customize Husky Gazebo model?
Thanks.
