back to article Mighty ROBOT achieves total SUPREMACY over feeble humans

No matter how many John-Wayne-inspired moments you've had in front of the mirror, you're not as quick on the draw as the Janken robot. Ishikawa Oku Laboratory in Tokyo has built the android to have a perfect score at rock-paper-scissors, identifying which way its human opponent is going to go in one millisecond. The boffins …

    Cheat the cheater?

    Wonder whether this would work or does the robot adjust itself again and again?

    Hmm...

    I suspect that the human could win this game every time - given a sufficiently large rock...

      Re: Hmm...

      Or some fairly ordinary scissors judiciously applied.

      Probably find a piece of paper in the right place would scupper it.

      But the rock would be most fun.

    Buridan's donkey

    What happens if the machine is made to play another machine, or in front of a mirror? Does it explode in a fit of recusive errors? I think in philosophy its called Buridan's donkey.

      Probably wouldn't do anything. It reacts to the motion of a human wrist. IIRC, that machine doesn't have what would qualify as a wrist. No stimulus, no response, no action.

      Re: Buridan's donkey

      To answer your question more correctly, what you're looking at isn't Buridan's Donkey (which is the problem of choosing between two options an equal distance apart and being frozen with indecision). Rather it looks like you're trying to start a classic deadlock. A device is dependent on an input, but connect two such devices to each other, and neither of them does anything because each is waiting on the other to act.

      I'm reminded of that song from around 30 years ago.

      I believe the firstly line went...

      "Well the members of the Argentine..."

      And IIRC it ended with "whipped margarine".

      Have you not seen the film Wargames when the computer plays naughts and crosses against itself? It'll be something like that, and it'll start playing chess instead.

    ...

    how does that work? there's nothing in the rules that says paper has to be shown as palm up, or that rock is anything more than a clenched fist - you can have your hand horizontal (so your wrist would be the same as if showing paper with palm down) or vertical and so wrist is in same orientation as scissors.

    In fact, no reason why paper has to be shown horizontally either.

    (is this explained in the video? it's blocked by the office firewalls)

      the video shows all three in the vertical plane.

    Hurray - Humanity is saved, the robot rebellion is now powerless.

    It thinks I am going to show paper, but instead I have a gesture control system that recognises a flat open hand as launch missiles at the doofus droid!.

    If the door was opened, and Arnie said "Sarah Connor?" then raised his hand and continued "I challenge you to rock, paper scissors."

    DOCTOR: Scissors cuts paper. Ha, ha! But suppose we were two computers controlling two great battle fleets, each one working perfectly logically to outmanoeuvre the other. Well, you're robots, you try it.

    SHARREL: We're perfectly

    DOCTOR: Try it! Go on.

    (The two Movellans come up with scissors and scissors twice, then stone and stone.)

    DOCTOR: Ha! You see? You're caught in an impasse of logic. You've discovered the recipe for everlasting peace. Congratulations. I'm terribly pleased.

    Of course the robot is actually cheating,if you watch the last slow mo decision in the video its waiting till the human finishes making a gesture before performing its own and even I can do that.
