Japanese Researchers Build Rock-paper-scissors Robot That Wins 100% of the Time

Posted by Unknown on from the humanity-is-doomed dept.

slew writes "Although the robot technically cheats because it watches your hand and can recognize what shape you are intending to make and beat it before you even know what is happening. Apparently it takes about 60ms for you to shape your hand, but the robot can recognize the shape before it is completed, and only takes 20ms to counter your shape so the results appear to the human opponent to be virtually simultaneous. I wonder how difficult it would be to add lizard and spock to the mix.... ;^)."

      Not a dupe, that was version 1 where it detects it after you form the shape with your fist, version 2 detects your hand as you are making the shape, so before you even finish it changes.

      That video looks like the slow version 1 (which makes no reference to there being any other versions), this video's the quicker version 2 (which explicitly refers back to the existence of prior versions).

      However, it still cheats, as it always follows the human. Perhaps the hands should be forced to touch down on a pad, such that the shape is defined at the precise instant that the first of the hands touches down. There are clear instances where the bot hasn't yet decided what to do. Or rather than doing its 1-2-3 counting by following, with lag obviously, the movements of the humans hand, it should have to follow audio counting by the human instead. That would permit the human to push the limits of mechanical lag in the same way as the bot can. If you can time that pushing perfectly, you can force the bot to default.

      So I don't think all is lost, this experiment is clearly set up to favour the robot by overlooking what it's unable to do. V3 might be faster still though, there's no reason to imagine otherwise, and eventually it will be so instantanious it's impossible to detect its lag.

    Since Rock-Paper-Scissors dates back to the time of the Chinese Han Dynasty, the Japanese built this in order to diplomatically resolve the dispute with China over the Senkaku Islands.

    Actually: in Japan, there's a "strip-poker" variant of rock-paper-scissors. The loser of each round removes an article of clothing. The game is a minor part of porn culture in Japan.

    Once again, porn drives innovation!

    When researchers build a rock-paper-scissors-lizard-spock robot. Then I'll be impressed.

    Why? It's just two more hand shapes, and the robot doesn't even need to use lizard or Spock (both rock and scissors beat lizard, and paper beats Spock).

      It won't complete the first round, as both will just sit there waiting for the other to move. "Never loses" might be the best way of describing it.
