Fail to use move group interface of the MoveIt! when connecting gazebo with Moveit!.

After I succeeded to connect the gazebo with Moveit!, I launched the move_group_interface.cpp but the Rviz failed to load the robot model and failed to recognize the Reference frame. As a result, the trajectory and motion of the robot cannot be displayed on the Rviz. The gazebo_moveit.launch file is:

<launch>

<include file="$(find slave_gazebo)/launch/slave_world.launch"/> <include file="$(find slave_control)/launch/slave_gazebo_states.launch"/>

<include file="$(find slave_control)/launch/slave_trajectory_controller.launch"/> <include file="$(find slavedarm_config)/launch/moveit_planning_execution.launch"/>

</launch>

The content of the moveit_planning_execution.launch is:

<launch>

<include file="$(find slavedarm_config)/launch/move_group.launch"> </include> <!-- The visualization component of MoveIt!--> <include file="$(find slavedarm_config)/launch/moveit_rviz.launch">

<arg name="config" value="true"/>

</include>


<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher">

 <param name="/use_gui" value="false"/>

<rosparam param="/source_list">[/slave/joint_states]</rosparam>


</node>

</launch>

The move_group_interface.launch file is:

<launch>

<node name="group_interface" pkg="moveit_myarm" type="group_interface" respawn="false" output="screen">

</node>

</launch>

After launch the gazebo and Moveit! launch file, the error information, with no effect on the system, is listed:

• MoveGroup using:
• ApplyPlanningSceneService
• CartesianPathService
• ExecuteTrajectoryAction
• GetPlanningSceneService
• MoveAction
• PickPlaceAction
• MotionPlanService
• StateValidationService

You can start planning now!

And after launch the move_group_interface.launch, the infromation is listed:

And after launch the move_group_interface.launch, the infromation is listed:

Pay attention to the Reference frame.It should be /base_link, not /world.So here is a mistake. And there are other errors as above.

Therefore, I don't know how to get the moveit, gazebo and move group together.
