Tutorial 1: Basic Robot Demo

This tutorial demonstrates the simplest setup for using MuJoCo with ros2_control.
It launches a two-link arm robot with position controllers using a pre-defined MJCF model.

Key concepts:
- Loading a pre-defined MJCF model from demo_resources/scenes/scene.xml
- Basic ros2_control integration with MuJoCo
- Position control of joints via position_controller

Usage:
    ros2 launch mujoco_ros2_control_demos 01_basic_robot.launch.py
    ros2 launch mujoco_ros2_control_demos 01_basic_robot.launch.py headless:=true

Control the robot:
    ros2 topic pub /position_controller/commands std_msgs/msg/Float64MultiArray "data: [0.5, -0.5]"
