I had been getting the error

I tried to run robot state publisher with this command:

ros2 run robot_state_publisher robot_state_publisher --ros-args -p robot_description:="$( xacro -/example_robot.urdf.xacro )"

according to this tutorial by articulated robotics (https://youtu.be/QyvHhY4Y_Y8?t=607) however i am getting the error:

Usage: xacro [options] <input>

xacro: error: no such option: -/
[ERROR] [1677169953.180432728] [rcl]: Failed to parse global arguments

I dont know if you're looking at this carefully, but you are supposed to use the '~' (tilde) character and not the '-'(hyphen) character.

Run this :

ros2 run robot_state_publisher robot_state_publisher --ros-args -p robot_description:="$( xacro ~/example_robot.urdf.xacro )"

P.S - Please make sure you have the urdf.xacro file present at the correct path when you run this.
