Yes, okay, so there's been a bit of delay between Round Three of our Robot World Cup and the quarter finals. They needed some oil after three rounds of knockout action (and besides, if the Cricket World Cup can last for what seemed like 17 years, I don't see why our robo-contest can't be strung out a bit).
Robots: they haven't taken over the world yet, but they're already capable of pouring us beer and controlling our home entertainment. If that's not a crafty strategy for leaving us sofa-bound while they stage a cyber-coup at some point in the future, I don't know what is.
Robots rule. Well, they don't yet, thankfully, because us humans have cleverly neglected to teach them about battle tactics, gun-handling or human-frying laser technology. But what I mean to say is: they're pretty cool. But which is the coolest?
