it's a radial arm with little finger like things at the end. this enables us to run up to a box (right-side up) and lift it using the underneath lip. when the boxes start to lift, there is a slight angle to them, but after which, they are perfectly perpendicular to the floor. the arms can only lift a little more than the height of one box, so in order to have a high stack we must pick up 2 and stack it on one, then 3 on one, and so forth. our arms also have the ability to flip boxes right side up from almost any orientation using grippy things (friction). good terminology there. the finger you see at the end (with the red cap) is used to straighten out boxes so that they sit in their set spaces on another box. and all of this is controlled by 2 pistons. yep. pretty pretty arms.
anything else?
maybe it's a good thing i wrote the chairman's essay. i mean, after all, grippy things and finger like things. yeah, go me.
