PROBLEMATIC LINE (in launchfile):

<param name="robot_description" command="$(find robot_description)/urdf/robot.urdf" />

SOLUTION: Change "command" to "textfile"

<param name="robot_description" textfile="$(find robot_description)/urdf/robot.urdf" />

The problem here was that command expects an actual program/tool/utility to run. $(find robot_description)/urdf/robot.urdf does not evaluate to a program that can be run, so you get a Permission denied error (as the .urdf does not have +x permissions set).

Got the same problem as using env_set and configs for xacro. +x permission solved it
