Hi,

I'm getting the following error while trying to bring up Turtlebot3:

andrestoga@andrestoga-pi:~/turtlebot3ws$ ros2 launch turtlebot3bringup robot.launch.py [INFO] [launch]: All log files can be found below /home/andrestoga/.ros/log/2020-09-19-13-16-32-654675-andrestoga-pi-10298 [INFO] [launch]: Default logging verbosity is set to INFO urdffilename : turtlebot3burguer.urdf [WARNING] [launch_ros.actions.node]: Parameter file path is not a file: /home/andrestoga/turtlebot3ws/install/turtlebot3bringup/share/turtlebot3bringup/param/burguer.yaml [INFO] [robotstatepublisher-1]: process started with pid [10308] [INFO] [hldslaserpublisher-2]: process started with pid [10309] [INFO] [turtlebot3ros-3]: process started with pid [10310] [robotstatepublisher-1] Initialize urdf model from file: /home/andrestoga/turtlebot3ws/install/turtlebot3description/share/turtlebot3description/urdf/turtlebot3burguer.urdf [robotstatepublisher-1] Could not open file [/home/andrestoga/turtlebot3ws/install/turtlebot3description/share/turtlebot3description/urdf/turtlebot3burguer.urdf] for parsing.

I have no clue why it cannot open that file for parsing... but the file is trying to open is empty.
