Movies like the Terminator series have convinced us that robots are eventually going to kill us all. That's still eventually going to happen but we've got a long way to go before we build a T-1000 or even an Arnold version, because as DARPA's 2015 Robotics Challenge shows, even the best and smartest robots right now are still so hilariously dumb that they can't even walk right.
We took footage of some of the best robot fails from the DARPA event and put a Benny Hill soundtrack over their falls. It's great! It's hilarious! But don't laugh too hard because you know the robots will come back and kill us all in a few decades.
