There are 8 joint controllers for my robot model, 4 of them belong to type effort_controllers/JointPositionController , and the rest of them belong to effort_controllers/JointVelocityController. Is there any method to adjust all the controllers that control the joints at the same time? It is better to have a graphic interface. Any opinion will be appreciated.

Assuming you have already set up the controllers through configuration yaml files and modified the urdf to add transmission interfaces then you can use rqt_gui to send commands to each controller.

Once you launch the robot with it's controllers then you can open the rqt gui with a new terminal using

rosrun rqt_gui rqt_gui

From here, there is a drop-down box to select the topic you would like to publish on, it should be something like effort_controllers/JointPositionController/command. Use the plus to add it to the list, modify the rate and expression you would like to publish and repeat for every controller.
