How to set start and end state in rviz motion planner

edit

@fvd I have aldready gone through that tutorial but they do not explain how to input your own start and end configurations of a robot.

I could imagine @fvd is (implicitly) referring to the Step 3: Interact with the Panda section, which mentions both the Query Start State as well as the Query Goal State.

@gvshoorn, that step allow you to mote the robot arm by interacting with it. What I want is to give my specific joint values to the start and end state.

That is not what you wrote in your question.

You wrote:

I want to be able to chose what start state and end state of a robot arm when executing the motion planner.

the tutorial @fvd linked allows you to do that. By dragging the interactive markers.

Have you also looked at the very next page of the tutorials which describes how to plan to a joint pose goal using the MoveGroupInterface, and also mentions how to set the start state?
