controll by using moveit

We are in the process of making a robot with both arms by modifying the open_manipulter package. We made two arms with urdf, but the control bar is only on the left arm. How do I get control bars for both arms? transmission_interface/SimpleTransmissionPositionJointInterfacePositionJointInterface1transmission_interface/SimpleTransmissionPositionJointInterfacePositionJointInterface1transmission_interface/SimpleTransmissionPositionJointInterfacePositionJointInterface1transmission_interface/SimpleTransmissionPositionJointInterfacePositionJointInterface1
