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 !!!

    Not special. You …
    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.

    @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

    @Zeidler What did you mean by “keep developing this little guy?” Isn’t he perfect already? 🙂 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?

    @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 This project was meant to creatively engage my kids so I disconnected the sound so that we don’t find out 🙂 BK
