I am using ROS noetic. Firmware is flashed as tutorial.
When I launch
roslaunch rosbot_description rosbot.launch or
the following error pops up:
RLException: while processing /home/husarion/husarion_ws/src/rosbot_description/src/rosbot_description/launch/rosbot_gazebo.launch: Invalid <param> tag: Cannot load command parameter [robot_description]: no such command [['/opt/ros/noetic/share/xacro/xacro.py', '/home/husarion/husarion_ws/src/rosbot_description/src/rosbot_description/urdf/rosbot.xacro']]. Param xml is <param name="robot_description" command="$(find xacro)/xacro.py '$(find rosbot_description)/urdf/rosbot.xacro'"/> The traceback for the exception was written to the log file
There seems to be an error in finding a xacro.py file?
There is no xacro.py in directory
'/opt/ros/noetic/share/xacro/ if it means anything.
