I did a generic search for this answer and I was not able to find what I was looking for.
I have two gates (well, one is a "cage") and I am trying to set it up so that as one gate opens, the other one closes: See the system in the open stage below:
If you look at the top of the unit, you will see that I have a sprocket and two idler sprockets (tension sprockets if you will):
Also note that I have a chain link modeled on top of a screw rod...there is a matching setup on the opposing gate. While i am not really looking to make this as an animation, I would like to show this in motion...so, as I manually lower the gate that is up, the other gate will rise.
How can I mate all of this together so that it will illustrate (manually) what I am trying to achieve?
