Lego Robot Plays Tetris 94

kkleiner writes "What's the surest sign that robots aspire to be more like humans? They play video games. The Tetris-Bot operates completely without human interference to play games of old school Tetris on a computer. Creator Branislov Kisacanin patched together a webcam, a digital signaling processing board, and some NXT Lego as a fun educational project for his kids."

          • That's the difference between man-made and God-made according to most religions. That reminds me of a joke I heard once. A scientist who perfected cloning confronted God one day and said "We don't need you anymore. We can create humans ourselves!" So God challenged him to a contest. If the scientist could create a more perfect man, God would leave. The scientist accepted and proceeded to pick up a handful of dirt. "Wait, wait, wait... hold on a second!" said God, "Get your own dirt!"

        • there's the biological definition of life: a few simple rules that apply to (nearly) all that we know of as "living".
          - it has dna
          - it reproduces (and can produce at least grandchildren)
          - it takes in substances and processes it into other substances for nourishment
          - something something
          - ???
          - profit! ... waaaait. something went wrong there.

          • According to your definition (at least the first half, which I take was still serious), mules aren't alive, since they cannot reproduce, correct?

            • well, my bio teacher explained that away with that it has to qualify for MOST of the rules he named, and mules didn't really come up. virii/viruses did, though.

        • I do know that dogs and cats have souls.

          Yes, they have R-souls, or they wouldn't be able to shit.

      • Is it not a life because it doesn't age?
        Life is defined scientifically as the ability to utilize resources to sustain oneself. In most basic terms, that makes it seem like a robot could be considered alive, except that it is completely and utterly dependent upon someone else to supply it that resource, and is not able to go out and forage for resources on its own. Some exceptions sort of barely apply.
        • Well if you bring religion into it, one could argue by that definition that we are not life either as we depend on God to provide us food through plant/animal growth.
        • Life is not defined scientifically, period. It's a perceived property. You can try to define it rigorously, but (as always, outside pure mathematics) there's nothing substantial separating the marginal cases on this or that side of the boundary. For myself, I'm not engaging in any more long-winded arguments about whether virii or fires are alive. If they are, then they hardly are; if they're not, then they almost are. Case closed.

    So will someone make Tetris blocks out of legos and come up with a robot that plays Tetris physically, perhaps even in 3d?

      • Well, one could use smooth-surface pieces around the Tetris blocks and there would be a hole in the wall at the level of the first block, so a mechanical arm could push the blocks on that line out of field. But that would require something else to hold the blocks together during the fall...

    This is a (probably expensive) DSP decoding the video and then the lego robot figuring out how to move. Give that robot some vision of its own, and I'll be more impressed.

    • The article mentions that it needed a webcam and a DSP. I can't watch the video here at work, but doesn't that imply that the robot does have vision of it's own?
      • The robot is redundant. Its only task is to press the keys on the keyboard. They could have made it a lot faster, cheaper, and more efficient by simply wiring the output directly to the computer's keyboard input. But that wouldn't involve any unnecessary Lego.
    • ...and they also put the (unused) sonar sensor on top the robot to make it look more human.
    • So glue the DSP and the webcam to the robot.

      Presto! Problem solved - a robot that plays Tetris.
