I can't control joints in correct order.

I can't control joints in correct order. I think there is a forward IK order issue here.

Please attach your model.  You will probably have to use a Motion Study to get the order right.  Motion Studies are hard to setup and control the speed but I think this will be your only solution.

 

If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I'm not sure I understand the problem.  I could not see a problem in the video.  Can you explain further?  The one comment I would make is:  There is no "order" to joints.  The entire joint system solves as one system.

If you would like to control the Joint movement in particular time sequence/order then I would use Autodesk Inventor Professional - Dynamic Simulation Environment with the Input Grapher.

Problem is part of the click and drag function. I don't need a timed sequence. There is a gripper connected to the robot arm you see in the video. When i click and drag the piece which is connected to de gripper program just moves the revolve joint beneath the arm part. But when i click and drag one of the gripper tooth it again trying to move whole arm. But ı want gripper to open it's jaws when i do this. It doesn't appear in the video (in the initial question, not the video in this reply) but used animate joint relationships function to animate single joint and it works. Drive joint function also works.  İt's actually not a big thing. I just wanted to ask.

If you attach your model, the Forum users can assist.  You might want to try Motion Links between Joints.  You will find Motion Link under the assembly tools.

yes, dragging a component is different than Animate Joint, is different from Animate Model, they are all slightly different.  Dragging a component tries very hard to put the component in the place indicated by the mouse movement (not always possible, due to other constraints, but it tries its best).  Animate Joint only animates the one joint chosen.  Animate Model tries to solve the entire joint system at once.  It sounds like you want two joints to move in tandem, in which case a Motion Link might help.
