Think outside the box

This is an interesting concept for a robot. Apparently it's self replicating http://www.news.cornell.edu/stories/May05/selfrep.ws.html
or at least that's the idea behind the robot. I have trouble getting my head around how it could be useful. I mean their boxes...and they move...around...and...some more...moving about. So there you have it, quite self explanatory. I'm sure when you see the video it all make sense to you. I'm sure there's a million applications for this; everything from box removal to box storage.
