I have a manipulator 6 DOF I can send it a pose with position and orientation and I set up a simple GUI using tkinter to publish the pose data for moveit to execute on RVIz. It pretty slower than what I expect I want it to be realtime but it take a period time about 6-7 second for every execution for 0.01 position to the next time press the button on GUI. Does anyone know how to make it better to get it realtime thanks in advance

Please read #q261368, I believe it is related.

If I understand you correctly you are trying to implement a jogging interface and then using MoveIt as the backend. That is not going to work. Or at least, I believe not in a satisfactory way (but to no fault of MoveIt).

I have already do the compute cartesian path but that is for already know trajectory but in my case I want to control robot by hand. Basically I want to control it in realtime .Is there any way to do that with ROS? like I use joystick analog to move arm and robot execute it synchronize thanks in advance

The referenced Q&A was about using MoveIt for something it was not meant to be used for. That is why I linked to it. Not to tell you about computeCartesianPath(..).

OK, as I thought.

Using a complete MoveIt plan cycle is not going to work in that case.

You could take a look at jog_arm which was recently integrated into the moveit_experimental repository. The wiki page hasn't been updated yet, but the version in ros-planning/moveit/moveit_experimental/jog_arm should do what you're after.

Note: it's not jerk-limited, so if your robot requires that, it probably won't work / need additional filtering.

please note: asking whether something can be done "with ROS" is not a question that can be answered. It's the components/packages/nodes that make up an application, not "ROS".
