Japanese Take Rock, Paper, Scissors Very (Very, Very) Seriously

Posted on by

Look at these people cheering and hopping around. You might think they just won some sort of cosplay contest or something judging by their outfits. But what you are about to watch is the aftermath of someone winning a Rock, Paper, Scissors contest.

I mean I haven’t played Rock, Paper, Scissors since I was ten and needed to work out who would get the top bunk at the sleepover. It turns out that Japan has a full on circuit for the game, also known as Janken Taikai. The contest has something to do with idols and the cosplay is apparently an integral part of the competition. Check out the excitement in the video below:

That referee is clearly a fan of Moe Howard from the Three Stooges.

A group of researches from the Ishikawa Oku lab in Tokyo decided to show what human-machine cooperation systems are all about by creating a robot that plays janken, Rock-Paper-Socissors.

What they created was a robot who never ever loses the game. How? Recognition of human hand can be performed at 1ms with a ...

Robot Will Destroy You… in Rock Paper Scissors

Posted on by

A couple of years ago we saw a glove that can play rock paper scissors. While that glove was smart – it learns from your patterns – it could still lose. This robot hand on the other hand will win 100% of the time, all the time. It’s not psychic, it just has insanely fast reflexes.

Scientists at the Ishikawa Oku Laboratary used a combination of a high speed camera and a fast moving robot hand, resulting in a rock paper scissors champ that recognizes what hand its opponent is going to play. In other words, the robot will wait for you to make your move before it decides what to play, but it all happens in only a few milliseconds that you won’t be able to notice it. Watch the demo below:

You know who can beat this robot? The glove. Problem solved.

Japanese robot trolls humans at rock-paper-scissors, sadly wasn't named the UMADBRO 9000 (video)

Japan got itself in the good graces of many a Futurama fan after creating Bender's ancestor. Then again, another Japanese robotic creation -- one that specializes in rock, paper, scissors -- may actually have more in common with the morally questionable, beer-guzzling bot. That's because this sneaky little future overlord wins 100 percent of its matches by using an oh-so human trait known as cheating. See, the researchers at the University of Tokyo's 4chan, er, Ishikawa Oku Laboratory programmed the "Janken" robot to recognize its human opponent's hand shape and counter it within a millisecond. Adding to the troll factor is the fact that it was unwittingly named the "Human-Machine Cooperation System" because, well, it needs the cooperation of some poor human sap to work its magic. The achievement joins other man-versus-machine milestones, including losses by humans in chess and shogi. Of course, the question now is, what happens if you pit two "Janken" machines against each other?
