This rudimentary robot hand, developed by the Ishikawa Oku Laboratory in Japan, never loses at Rock, Paper, Scissors. It has a perfect record against everyone who's ever challenged it, but that's only because it can see and react faster than any human being can.

Using a high-speed camera the position and shape of the human competitor's hand can be recognized, at which point the robot will play whatever it needs to win. And this all happens in about 1ms. It appears as if the robot is playing fairly. But it's not. It's actually blatantly cheating. But in this case that's a good thing because it shows that man and machines might actually be able to work together very closely one day. Doing construction, exploring the stars, or just roaming the country as conmen. [Ishikawa Oku Laboratory via Automaton]
