robot model error in rviz

[Abduoit]

Hi

I want to run the arm in rviz,

This is my launch file

<launch>
    <node name="arbotix" pkg="arbotix_python" type="arbotix_driver" output="screen">
        <rosparam file="$(find pxpincher_config)/config/pincher_arm.yaml" command="load" />
    </node>

  <!-- Now load robot model -->
  <param name="robot_description" command="$(find xacro)/xacro.py '$(find pxpincher_description)/urdf/pincher_arm.urdf.xacro'"/>
  <node name="robot_state_pub" pkg="robot_state_publisher" type="robot_state_publisher"/>    


  <node name="gripper_controller" pkg="arbotix_controllers" type="gripper_controller">
      <param name="model" value="singlesided"/>
      <param name="invert" value="true"/>
      <param name="pad_width" value="0.0254"/>


  </node>

</launch>

But I get robot model error in rviz as follow

gripper_link
No transform from [gripper_link] to [base_link]

I solved it by removing the following lines from the file pxpincher_description/urdf/turtlebot_arm.xacro

I do not know is that correct or not, I am afraid it will give me error when I want to do further arm control.

    <!-- fake gripper_link joint gives us a free servo!
         this makes us 5DOF and saves you $44.90
         that's a lot of coin! -->
    <link name="gripper_link"/>
    <joint name="gripper_link_joint" type="revolute">
      <origin xyz="0 0 0.112" rpy="0 -1.57 0"/>
      <parent link="arm_wrist_flex_link"/>
      <child link="gripper_link"/>
      <limit effort="30" velocity="1" lower="-3.14" upper="3.14"/>
      <axis xyz="1 0 0"/>
    </joint>
