Description

move_group.launch.py in franka_fr3_moveit_config will not run unless the following are declared as launch arguments and added to the LaunchDescription, as in moveit.launch.py: namespace, fake_sensor_commands, use_fake_hardware, load_gripper.

Otherwise, launching e.g. with ros2 launch franka_fr3_moveit_config moveit.launch.py robot_ip:=dont-care fails due to the following respective errors:

[ERROR] [launch_ros.actions.node]: Error while expanding or validating node name or namespace for 'package=moveit_ros_move_group, executable=move_group, name=None, namespace=<launch.substitutions.launch_configuration.LaunchConfiguration object at 0x73bb090fd930>':
[ERROR] [launch]: Caught exception in launch (see debug for traceback): launch configuration 'namespace' does not exist
[ERROR] [launch]: Caught exception in launch (see debug for traceback): launch configuration 'fake_sensor_commands' does not exist
[ERROR] [launch]: Caught exception in launch (see debug for traceback): launch configuration 'use_fake_hardware' does not exist
[ERROR] [launch]: Caught exception in launch (see debug for traceback): launch configuration 'load_gripper' does not exist

This was tested tested on ROS (2) Humble, Ubuntu 22.04 LTS.
