Hi all, I am using gazebo RRBot Example with ros_control, as the follow tutorial: [ http://gazebosim.org/tutorials/?tut=r... ]

the rrbot has two joints, joint1 and joint2. I changed joint2 controller from effort_controllers/JointPositionController to effort_controllers/JointEffortController when I run it, I found the joint2 only have one /rrbot/joint2_effort_controller/command topic, that was different from joint1. I want to know is it was ok? image description
