  1. Can you please! confirm that you have dashgo_description/urdf/dashgobase/dashgobase.xacro following file at this path.
  2. Did you build and source it before running the program?

Are you sure you have the ros package that is for noetic? You may run into many weird issues if this package is actually intended for an earlier version of ros.

I think the problem may be the $(find xacro)/xacro.py, because xacro.py has changed to just xacro in noetic. You need to edit your launch file to remove the .py filename extension from that line.

It's likely xacro itself isn't installed. I'm also not sure default will run xacro. But it would depend on what the rest of the .launch file does.


Edit: this can work.
