<node pkg="rviz2" exec="rviz2" name="rviz2" output="screen"/>
<node pkg="robot_state_publisher" exec="robot_state_publisher" name="robot_state_publisher">
    <param name="robot_description" value="$(var robot_description)"/>
</node>
<node name="joint_state_publisher" exec="joint_state_publisher" pkg="joint_state_publisher"/>
<include file="$(find-pkg-share ros_gz_sim)/launch/gz_sim.launch.py">
    <arg name="gz_args" value="-v 4 default.sdf"/>
</include>
<node pkg="ros_gz_sim" exec="create" args="-world default -file $(find-pkg-share gazebo_pkg)/urdf/total.urdf"> 
</node> 
<node pkg="ros_gz_bridge" exec="parameter_bridge" args="/chatter@geometry_msgs/msg/Twist@ignition.msgs.Twist"/>
</group>
</launch>
