NXT Robot playing connect 4!!

[vegantimetolove]

Holy crap. That's awesome!! I love lego almost as much as I love Connect 4 ;-) I used to always build lego robots using some stepper motors controlled from an old 386's serial port with programming done in GW Basic programming. I wish I'd thought to do something this cool. Good job.

[Luyihan]

Not the smartest robot, but at least it won.

WE WANT A ROBOT THAT DOES OUR HOMEWORK!

[schmarre777]

Hey Man i absolutely need your help... do you know how these "corrugated" long bricks are called....(so those, which fit with these wheels to move the sensor right and left) i don't have them in my basic NXT-Set and it's hard to do something like that witihout them. Thank you

[gulbgulb]

@schmarre777 hm i dont know how they are called, but i got them from old lego technic kits... im sure you can order them. but you can also build similar mechanics without those ;) be creative

[gulbgulb]

@schmarre777 thanks :) good luck with your project!

[DigitalClark]

If a video is great, it doesn't matter which quality it has! Great!

[janixus]

cooooooool

[349E]

Well done. Using complicated machines to achieve inane tasks. That my friend, is the true purpose of robotics.

[ripstikchild10]

where'd u get that connect 4

[ChuffChuffWoo]

I want to see two of them playing each other!!

[Phygar1]

lol, you stink at connect 4.

[SuperWizTech]

this is pure awsome

[UndeadSoldier3]

lol this could take a while

[lilkidalex1]

so? I built a bebe self shooting Nxt Robot

[stefa1687]

can you put a LDD file?

[dodgey99]

I'd love to see the source code....?

[gulbgulb]

hey, i programmed this a year ago and with kind of low-skill, you know. So the programm is long and hasn´t got a proper structure. But it´s surely possible, that you can see it. send me your email adress in a pm and iíll send you the prog, okay?

[dodgey99]

very impressive - I'd love to see the NXC code - is that possible?

[gulbgulb]

no way!

[NXT20831]

I saw a way the NXT could of doble trapped you.

[ManiacCraniac]

Well, it plays decent, but you flat out stink at connect four :p.

[Leckeeer]

ich finds seht interressant

[gnudlibba]

hey das is echt geil

[MasterOfMasteratude]

SO KEWL!!!! 5/5

[kikaro11]

are thear diff. levels of challenge?

[gulbgulb]

@kikaro11 jea, i added some different difficulties.

[kikaro11]

thats amazing i want a nxt lego set now more than ever

[gulbgulb]

@kikaro11 get it! it´s worth it!

[FCBarcelona6Xavi]

its take 5 h for one match..hhhhhhhhh!

[gulbgulb]

yea

[cuber188]

where do you get the rack and pinion or watever

the teeth thing?

[gulbgulb]

okay, i´m not sure what you mean.

The Lego bricks, wich have those teeth like a gear?

I got them in some Lego packages before, but you can also buy them seperate, i guess.

[funorbzombie]

lol how much the robot cost?

[gulbgulb]

last year it was 250 euros, but now there is a version 2.0, so i thing NXT 1 got cheaper.

[Pikman01]

LOL, It tricked you! XD

[gulbgulb]

Yeah, but that was for demonstrating purpose only... :)

[xFootballrx]

are those lego's haha... thats SICK!

[Rendszergazdajelszo]

Hello

Could you please create an LDD file and upload it somewhere?

Thanks, Daniel

[gulbgulb]

LDD is a virtuell instruction, right?

the problem is, the robot is not competely from the nxt set, there are alot of "special" pieces in there.

[mesart]

Awesome robot. Thanks for sharing. But really, is NXT processor that slow? There are really strong (and exact) heuristics for connect four given in for instance Msc Thesis of Victor Allis. I think there was even an open source implementation that can solve the whole game in minutes

[patatas89]

Nice video and nice programming! ;) I have programmed my lego robot too for a contest. The aim is to make the robot to put 2 kinds of balls in the appropriate holes. It's kind of difficult though but I'll do my best! :) 5 stars for your video! :)

[DronElektron]

Very Nice! How you make this perfect program? She big???

[gulbgulb]

^^Thanks! unfortunaly the programm isn´t perfect yet...if you want the programm, pm me then i will send it to you. what do you mean with "she big??"

[gulbgulb]

sorry for the pour quality, i´ll soon try to upload a better version. watch out
