How would you do this? Lowering / Raising a claw

Hi, all,

I am trying to use an animated claw, which opens and closes to drop down and collect an object similar to an arcade claw machine. The claw is attached to a controller via a hinge joint and I would like to somehow lower it and retract it within a short period of time.
Is there any code that would extend the hinge joint or uncouple / recouple it to allow the claw to drop?

Thanks,

Greg
