Normal pneumatic cylinders "want" to be either extended or retracted. Doing any sort of in-between control is not simple, and it takes a lot of careful design to make it work well.
How much pressure do you need the arms to squeeze the totes with? If you choose the size of the cylinder appropriately, you can apply the right amount of pressure no matter how big the thing between the arms is.
