While this may not sound like much it can be significant depending on what you are trying to accomplish.

I didn't think about that, but you are correct. Regardless it is unlikely that Aroki's success is correlated with pulling instead of pushing but rather the angle and position that the pneumatic cylinders are pulling at.
