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

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.

      Version 6 looks really hot, especially while she beats up Version 4.

    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!

    Dice doesn't have dedicated slashdot editors anymore. They are editors of a dozen or so sites. Really now, what kind of quality do you expect now that they've sold out and now monetize the web synergies to create a new market paradigm of customer-focused informational advertisements?

    Have it play against itself, then we'll see some small values of 100%.

      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.
