I need someone to explain this to me.

Robotic rock-paper-scissors never lets you win

So robots kick our butts at tic-tac-toe, chess, Jeopardy, and now they’re the dominant species at rock-paper-scissors too. This robot arm will outmatch your at the game every single time. It’s not just fast enough to keep up, but it figures out what you’re planning to do and reacts according. All of this happens way to fast for you to catch it in the act.

Researchers at the University of Tokyo came up with the idea of combining high-speed vision with a high-speed hand. Apparently one millisecond is all it takes to analyze what move you’ve chosen. The time it takes for the hand to form the conquering position is only marginally longer than that. As you can see in the clip after the break, it already knows the protocol of 1-2-3 shoot and doesn’t need any operator intervention to start a new game, or repeatedly school you on trying to compete with a machine.

We’ve been beaten at the game by a machine before. This is just first time that the human player doesn’t need to wear special equipment and the machine has moved from a virtual hand to a physical one.

    A robotic hand going up and down, in Japan. Am I the only one to see how it will probably go from there?

    Now with built in nails on a chalkboard!

  3. jeditalian says:

    i think i could beat that machine

  4. jeditalian says:

    actually, it would probably just switch as soon as my hand did. then i would drop an EMP grenade and use paper to cover its rock.

    What about rock, paper, scissors, lizard, Spock ;)

    Is it really beating you considering it is just cheating?

  7. freezedream says:

    I’m with bluewraith. It is a rather clever example of the technology involved but does not play by the rules. It obviously doesn’t commit to which hand it is going to play before you do, so of course it will win. Perhaps a more suitable challenge would be to have different competitors pit their own robots against each other.

    It is nice to see it respond quickly in the slow motion video. But it IS cheating!

    :P

    looks like a remarkable and promising advance in cv development

    still needs to obey asimovs 3 laws of robotics though

    Nurse- “Where’s the rest of the robot?”
    Howard- “I only built the hand”
    Nurse- “Because thats all you needed right?”

    Yes its been said before, I just had to toss it in.

    I can think of a way to foil it.

    As you’re moving your hand downward, start to make a scissor gesture, then quickly change it to paper as you complete the move.

    Or start to make paper, then switch to rock.

    I’m already making the same thing…
    When I play this game I stare the hand of my opponent, and starting to make the rock…
    Depending on what I “guess” about my opponent choice I will leave my hand as is (rock), or I will starting to unfold two fingers (scissor) or the four (papper)…
    But I concede that I do not win 100% of the time since the loop feedback from my eyes to my hands through my brain do not take “only” 1 ms…
    Maybe one day…
