Boston Dynamics builds thinly disguised military robots that are meant to be very flexible and can operate in rough terrain (for 15 min or whatever until the battery runs out, but that's another story). They're hugely expensive literal overkill for a highly predictable and controlled environment like a warehouse, which is why the Kiva robots that Amazon actually uses are basically boxes on wheels.
