I'm working with ROS2 dashing and following this thread: https://answers.ros.org/question/3543..., I cloned the dashing branch and built xacro. However, I do not know how to use it; is anyone familiar with using xacro in ROS2?

Hi,

To use XACRO in ROS2 you need to process the XACRO and convert it to xml:

import xacro

xacro_file = os.path.join(get_package_share_directory('box_car_description'), 'robot/', 'box_bot.xacro')    
assert os.path.exists(xacro_file), "The box_bot.xacro doesnt exist in "+str(xacro_file)

robot_description_config = xacro.process_file(xacro_file)
robot_desc = robot_description_config.toxml()

I'll leave a git as an example for this of how to spawn a simple box robot that uses xacro, have a look at the spawning scripts:

Hope this helps
