Robots Fighting

This is more for a laugh than anything else, but I figured I would put up a slightly different side to robot competitions.  I remember when this used to be a big deal and you could watch these "battles" on ESPN and the like. It is somewhat inane watching robots destroy each other but it is neat to see the ingenuity of some of the contestants and how serious the guy looks when he loses his little warrior. The more I look for videos with robots dancing or fighting like this one, it makes me wonder more and more just how much could we accomplish with robotics?
