Motion link between multiple slider joints with different limits

Anonymous — Sat, 24 Oct 2020 03:27:23 GMT

I have a series of joints I would like to be able to slide in tandem, but with varying levels of maximum extension.

Is there a way to link their motion so I can use a single slider to move all joints at the same rate of speed but allow the components with larger travel distances to keep moving once the less mobile components reach their limit?

Current motion (all joints motion linked, linked in descending order of range magnitude, driven with largest slider):

After which, no joints will move any further inward.

Desired motion, using a single drive slider (accomplished in these images by moving each set individually):

Is there a way to link this kind of telescoping action or am I stuck moving each set to animate this? Or is there maybe another approach I'm not thinking of?

The project is just a non specific personal project, no intended use. I can post the file if that's helpful.

Thanks (:

The answer to your direct question is NO, you cannot use Motion Links to do what you desire. You can use a Motion Study however. The only problem with Motion Studies is you cannot get them to move slow enough when you run them in automatic mode. Of course you can manually run them at any speed you desire. I have created a smile demo Screencast and I have attached the model I used.
