Lego Robot Plays Tetris

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."

      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?

      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.

  22. What about more complicated games by The_Duck271 · · Score: 1

    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."

    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.
