Tetris-Bot (TI DSP + Lego NXT robot)

Tetris-Bot is a Tetris-playing robot. Jay Leno would say "How lazy are we getting? Now robots play games for us!" Well, not exactly, but I agree, we are getting lazy. I made it in order to engage my kids in a fun and educational project. Tetris-Bot consists of a camera, a TI DM6437 DSP board (running my embedded vision and artificial intelligence algorithms), and a three-finger NXT robotic hand (that presses the keys on the computer keyboard). I was inspired by the NXT Rubik and Sudoku solvers and the Segway-like NXT robots. Unlike them, Tetris-Bot is not an NXT-only system, because the Brick has a limited input bandwidth. That's why I use a TI DM6437 DSP board to analyze the images coming from the camera, recognize the new shape, and find the best place and orientation for it. The instructions are communicated to the NXT robotic hand via LEDs on the board. HOPE YOU LIKE IT !!!

Thats just crazy AND lazy :D Bye the way what country are you from, because your name reminds me on mine (Slovenia).

@Zblj1987 Hvala! Sem se rodil in odraščal v Novem Sadu. Zdaj živim v Ameriki. :-) BK

That's really cool actually, are you planning any other similar projects or will you keep developing this little guy - and if so, how?

[BranislavKisacanin]

@Zeidler What did you mean by "keep developing this little guy?" Isn't he perfect already? :-) BK

[BranislavKisacanin]

@Zeidler These are the same questions I am trying to answer myself. On one hand, I am tempted to keep working on Tetris-Bot, on the other hand, it served the purpose I had for him - keeping my kids' focus off the games for a few weekends. If I decide to keep working on it, that will be over the summer, focusing on the AI algorithms. If I decide to release it to public domain, it will likely be the Open Source for the Leopard Board. Or just sell it on eBay and get rich :-) BK

Does the little dude ever swear? I use to swear up a storm playing Tetris.

[BranislavKisacanin]

@sw0rd0fadvers1ty This project was meant to creatively engage my kids so I disconnected the sound so that we don't find out :-) BK

Lets see how fast it can play now...

[eracab]

Chuck Norris can beat nxt on tetris

[guthimidious]

fdsfds

[bioshock123458]

Congrads dude, ya can make an array and a bunch of if then statements....

[Supersomonerandom]

Cool, but that "not bad for a robot" is stupid sentence. Of course, if its programmed by u, but in general you can make a bot thatd play tetris better than any human

[SOPM2007]

I by myself have already created a Tetris Bot which was a very interesting project. And now I am on the way to make a new one with a improved "AI"-algorithm. Also it will be able to perform Tetrises (clearing 4 rows at once) if the user want to force this.

[SOPM2007]

No, I am not wondering why making a video about Tetris because for the very reason that it is one of the most long-term addictive games ever.

[CillersFan]

This is really cool! I was thrown off with the legos though. I always thought of them as just a toy, but I guess they could work well for Testris bots though.

[ScOrPiioOX]

Ok now, let's play Pacman

[gami323]

cool

[brattty13]

can it play other games like pac man or something i love tetris though

[ArthurD125]

Nice^^

[mhordekaos]

Skynet Detected!

[MsDeadDude]

Wow thats useless but still cool

[Evi1M4chine]

Not special. You only need a small script to automate Tetris playing. Its extremely simple. Speed is what makes it hard for *humans*. The rest is just pointless I/O made for humans: Input: webcam → black/white contrast enhancement → grid tiling → 2d array of bits; Output: left/right/turn/down bitfield → bitflip toggles state transition function of fingers. → that function calls motor start, delay and motor stop.

Easy peasy.

@SoulblinderAD without the "geeks" with too much time we wouldn't have anything what you today take for granted, like electricity, computers,, etc, etc. Advacement in technology must start somewhere even if it's "only" a robot playing tetris..

[sw0rd0fadvers1ty]

@BranislavKisacanin Haha, good thinking!

[IPUNCHEDALION]

nice work, now get it to play TETRIS GRAND MASTER
