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."

But the chemical composition of human beings changes that? You do know that your brain simply processes electrical signals right, and that we've made great strides in using man made robotic components to send signals to the brain, thus furthering the notion that we are not all as different as you seem.

Yes - we've heard it all before, they just run programs. What if we manage the impossible taks of reverse engineering all the things that make being human into a mathematical algorithm and have a robot run the script? Is it not a life because it doesn't age?

Em Emalb (452530) | more than 4 years ago | (#31912216)

I dunno. Depends on where you're coming from. If you're a believer in some religions, then no, it's not a life because it doesn't have a soul. But if you're an atheist, then it could be, except it doesn't "die". So I dunno.

I agree with you. It's one of the reasons I was turned off of religion at a very early age. (Was told that my dog that had just died didn't have a soul so it wouldn't be in heaven when I made it.)

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!"

I do know that dogs and cats have souls. Some humans don't.

You do know that dogs and cats are engineered to get along with humans, by humans, don't you? So if they have a soul, then we have created it. Actually I'll stop fucking about - that comment is moronic beyond all categorisation. You have set yourself up to judge which entities have souls, it just happens to coincide with animals that we've bred to live alongside us, and excludes some "nasty" humans in your opinion.

IMO... Dogs and cats don't have souls. People don't have souls. Arguing about souls does not actually mean anything, nor accomplish anything, especially if you are arbitrarily assigning souls to entities that you like.

Re:Whiskey Tango Hotel (1)

Em Emalb (452530) | more than 4 years ago | (#31914382)

You do know that dogs more than likely domesticated themselves right? And that cats, according to a lot of scientists and behaviorists, aren't really even domesticated at all?

You also do realize the above comment you're referring to was a "throw-away" comment on an article about a stupid tetris playing lego machine? Right? If not, not really my concern. Moronic comment? Please. I can do much much worse.

IMO... Dogs and cats don't have souls. People don't have souls. Arguing about souls does not actually mean anything, nor accomplish anything, especially if you are arbitrarily assigning souls to entities that you like.

You definitely do not have a soul. And if you did have one, I doubt God would have any mercy on it. (See, I'm still joking here. I don't care what you believe)

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.

Re:Whiskey Tango Hotel (1)

tompaulco (629533) | more than 4 years ago | (#31913408)

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.

Re:Whiskey Tango Hotel (1)

Jake Griffin (1153451) | more than 4 years ago | (#31914170)

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.

Re:Whiskey Tango Hotel (1)

timeOday (582209) | more than 4 years ago | (#31914896)

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.

Hmm. if the robots we create, that interact with us in such an engaging way, create a demand for mass production, and if the factories begin to receive feedback from us about what kind of robots we want, improving their capacities and ability to stay engaged with us, then we have created a cybernetic feedback loop and a primitive form of evolution, which could be considered the beginnings of an semi-autonomous living organism living in symbiosis with us, with the robots as the sensory apparatus/spores. cute, fun, engaging, useful, cant live without them. forget skynet, we will be driven to distraction by super high tech tamagochis. remember, life is autonomous movement against entropy. there is plenty of usable physical and mental energy in human society for a cybernetic robotic production system to feed off of. human civilization is the SUN, and the robots are the primitive life forms enjoying waves of energy helping them to self organize. i for one bla bla bla.

Alright, smarty pants, they'll make tetris blocks out of LEGO® brand building blocks. Probably easier with Duplo or Quadro.

There would have to be a way to limit rotation to only one axis (easy to do with two sheets of plexiglass), and also a way to do the rotation in that axis (much harder with plexiglass in the way). Maybe forget gravity and make the robot "drop" the pieces by holding on to them from the start, then you could switch to a table, and have more stability, also you could use gravity to your advantage to remove rows (slide the whole tetris construct down and use a wedge to separate the last row, letting gravity drop the pieces into the piece reconstruction bin to be put back together (a more difficult visualization task)

Re:Next Physical Tetris? (1)

Culture20 (968837) | more than 4 years ago | (#31914818)

How would you remove a row from the middle or top though?

Hmm, I clearly shouldn't design LEGO mindstorms tetris games while working; the work is distracting. Unlike a human, the computer could prevent itself from "thinking" about the move while it took extra time away to clear rows by some complicated method, but that makes it a less interesting for humans to watch (which I believe is the ultimate point).

Re:Next Physical Tetris? (1)

greenguy (162630) | more than 4 years ago | (#31912880)

Re:Next Physical Tetris? (1)

BoppreH (1520463) | more than 4 years ago | (#31913322)

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...

HTH NE1 (675604) | more than 4 years ago | (#31912902)

I've thought about this back in the days of Pacman and Defender about the feasibility of creating a machine with vision and mechanical access to the controls of a game if it could be taught to play indefinitely (at least for the games that had no real end).

I don't think this is the first time it has been applied to Tetris. But it shouldn't be hard to solve Space Invaders. Asteroids would be an interesting challenge. A computer playing Centipede perfectly would be very impressive (if it had to physically spin the trackball).

Of course there are games that get ridiculously difficult such that no one could ever play them indefinitely without infinite credits (Off Road would get to the point where you needed to constantly hit the Nitro 99 times to practically fly around the course, and still the grey computer car would manage to set record times beating you, and which you'd have to buy-in to refill).

It'd be interesting to make a bot like this that plays MMOs or something equally repetitive -- is that against terms of service? How would they know?

I remember making a "robot" to beat Ruby Weapon in FF7, which consisted of a coffee cup pressing the X button -- the fight took 2 hours thanks to summon animations.

Wouldn't that just attack? No summons no inv and you would get owned? Plus I mean if you wanted to cheese an optional boss that was just there for you to have fun with there are many ways to end the fight quickly. Lucky 7s, Vincent bug, etc.

Nope. You put cursor on "memory". You let every party member die except 1. After the you have one party member left, you use the materia allowing you to multisummon. The first summon puts the boss to sleep (hades? It's been a while) but does little damage. 2nd summon does damage of your choice (bahamut? Doesn't matter really. You could actually beat it with just hades, but it does so little damage...)

Mime. With sufficient haste, you can then simply mime again for the rest of the fight. Ruby never wakes up. You put the coffee cup on once you've got it down to simply miming and the cursor having memory completes the fight.

I did this to show that you don't need to gold chocobo because you get a gold chocobo as a reward for beating ruby.

I misspoke. You actually use hades second. First summon does damage, then he's immediately put to sleep by hades.

Bricks for bricks... (2, Funny)

...So a robot made of bricks playing a game, in which bricks fall down... nice touch...

What about more complicated games (1)

The_Duck271 (1494641) | more than 4 years ago | (#31916350)

A bot to do this for a more complicated games like FPSs would be interesting. To play well would involve solving a number of AI/computer vision problems. The bot would have to pick out enemies from the image it was seeing, it would have to figure out where it was on the map from visual cues and determine where to go, and so on. It would be a simplification of the problem of creating a robot that can intelligently navigate its environment, with the actual physical robot abstracted away to "push the stick forward to run."

Is that just me, or ist the bot crap at Tetris? (2)

Sorry folks, but while I'm a total n00b when it comes to robots, I believe I could come up with a much better Tetris solving programm in a single day. Is it just me or is that bot really bad at Tetris?

Probably the least interesting part is the algorithm to play Tetris. Could you do a better job in a day? Maybe. The interesting part is the DSP/robot aspect of it. Anyone can write a program to play checkers or chess or whatever. Getting the program to rely on external sensors and be able to manipulate its environment...now that's cool.

But it seems like its doing it the stupid way. Judging by the speed, its scanning the entire field. Knowing the rules of tetris, thats simply not needed. All you need to do is know the dimensions of the field and the history of your current game (which you can record since you started it)

All you need to scan is the current piece, apply it to your known gamefield, then update your internal gamefield representation and repeat. Theres no reason to not be doing this at full speed.

Yawn. (1)

Of course it can be solved with a simple algorithm. Using peripherals made for humans, of course makes it harder, but in this case not very much.

Anyone know anything about the AI behind this? Tetris is NP-Complete, so how is it solving it?
