ここでCtrl-Cとすると、以下のメッセージが出て、shutdown errorとなってしまいます。

ここで、エラーを出しているcontroller_spawnerは次のlaunchファイルからlaunchされています。

<launch>

  <!-- Load joint controller configurations from YAML file to parameter server -->
  <rosparam file="$(find rrbot_control)/config/rrbot_control.yaml" command="load"/>

  <!-- load the controllers -->
  <node name="controller_spawner" pkg="controller_manager" type="spawner" respawn="false"
    output="screen" ns="/rrbot" args="joint_state_controller
                      joint1_position_controller
                      joint2_position_controller"/>

  <!-- convert joint states to TF transforms for rviz, etc -->
  <node name="robot_state_publisher" pkg="robot_state_publisher" type="robot_state_publisher"
    respawn="false" output="screen">
    <remap from="/joint_states" to="/rrbot/joint_states" />
  </node>

</launch>

お手数をお掛けしますが、よろしくお願いいたいます。

基本的には気にしなくてよいとおもいます
ps -aux | grep controller_spawner
をして残っていればkill -KILLなどで殺して下さい．

教えてもらったとおりにしたところ、以下のような結果になったので、おそらく大丈夫だと思います。
ありがとうございました。
