thanks for the help, are there suggestions as was done undulating movement of rhombs, I mean when the controller move to the left side of rhombs, then rhombs in direct proportion to rise up to each other. this model is Malcolm I took it from the site of the animation. I'm tired eviscerate his like a Christmas duck. If you select rhombus and open expression panel you will see that they are linked, but at the same time, if you will move the controller rhombs are no restriction of moving, as well as when you open an animation curve editor, you can see the keys and animation curve through which you can edit Range of the rhombs.

All right guys. I solved problem. Everything is done through the link and constrain "Position" .
