You may have already seen this on Instapundit, but on the off chance that you missed it, check out this pack mule robot from Boston Dynamics.
It's one of four different models, and though it creeps me out just a bit, it also makes me laugh. Check out the video. I swear, the thing appears to be mincing. In fact, it reminds me of nothing so much as two skinny French mimes trapped head to head in a gigantic aluminum chinese finger trap. Magnifique! C'est le "high concept", non? You will admire the black leotards!
