I work with the systems on a warehouse where robot arms similar to these are doing stacking of boxes. It's not really that efficient. Using robot arms is the natural improvement when automating a previously manual step, but rethinking the whole process instead yields a much bigger boost.

At least that's what we hope with our new process soon up and running.. If anything, the new automation process is much simpler at least, there are sooo much that can go wrong with big robot arms. They look cool, though, great for recruiting.
