Hello @amithelfand,

There are many reasons to have this problems, some common ones are:

  • File is missing - you have to make sure you have move_robot.launch in your exercise_21/launch folder
  • Package not compiled - execute catkin_make in your workspace and source ~/catkin_ws/devel/setup.bash and try again

Please let me know if it worked.
