Hey, how did you make the head go up and down? It looks like a bendable Technic axle...

[BlueToothKiwi]

Yeap - it is. Not the perfect solution - looking back.

[vykac]

[daniky999]

[banananana33333]

i have the same phone but i have trouble connecting the NXT 2 it. u use the windows i-mate k-jam rite? how did u control the bot? i need help! SOME BODY HELP!!

[3mustardMoNkEyS]

ok i have seen how the NXT can control the PF Motors but I'm trying to control the PF motors with my RCX. Is it possible and if so what are the IR Numbers i need to send to control the PF?

[Blayzeing]

This is one of the best youtube videos I have ever seen!!! The head movements and song both ROCK!!!

[billyboy385]

very nice!! i love it!

[BlueToothKiwi]

Thank you.

The NXT is controlling it using the IR-Link which mimics the infrared signals. Some of the shots (e.g. the beach) were done using a Bluetooth remote - as I did not trust an autonomous robot next to the sea - just incase it decides to carry on into the water!!

[Chrutonius]

Awesome burnouts on the beach!!! :D

[XBillums]

Are PF motors more powerful than NXT servomotors?

[BarneyEire0900]

Cool...Really impressive,the song sets it off...Love the rabbit mincer!!:D

[vakama380]

Poor bunnies(but cool robot)

[cooool742]

[stev231]

[carachelo]

[sjipogsjap]

lol ! so easy too make .

[yemilb]

gr8 song :D

[sk8shred]

can it steer?

[sk8shred]

hehe

[BBballfanatic13]

torture the bunnys eh?

lol nice tobot where did you get the motors?

[chapadwa]

I think its funny, a robot scooping up green stuff while the song "Puff the magic dragon" is going... hillarious

[BlueToothKiwi]

Really? You sure it is LEGO? I am not aware of any other LEGO motors that has the power and torque that matches the TECHNIC PF-XL motor - but then again I am not familiar with motors released before this year.

[metaleater9]

um.. how dose it stear

[BlueToothKiwi]

The two rear wheels are each powered by separate motors - effectively a differential drive. The single front wheel is attached to the chasis using a turntable - which is free to turn.

[theassociatedlosi]

that is by far the coolest nxt thing ive seen on ytube!

[Killingpeet]

Real smart. But are there other ways except via a bleutoothphone to control the NXT???

Futher great vid and music

[BlueToothKiwi]

Killingpeet, You have two options:

(1) Semi autonomous operation: NXT uses the ultrasonic sensor and other sensors and then controls the motors

(2) Complete Autonomous operation: The Windows Mobile acts as a high level brain (in conjunction with the camera image) and make intelligent decisions and then control the NXT via Bluetooth.

Hope this helps

[Killingpeet]

Very nice car, i have only one question: Is it remote controlled? if it is how you control it TY

[lpkok]

Hey congratulations, very nice vid, the robot is very nice and multi functional I liked too that he's very fast. Oh yes the bunnie was very nice

[WildernessSurvivor]

Whats this song called?

very nice vid

[AidanHockey34]

i love it in every way! i love to 8572 ( i think thats right ) stickers for eye brows! looks like WALL-E`s. hey, the white axel conected to the rotating head making it go in the y direction, how can it flex so much!?

[foxtrotHQ]

I'm gonna get the dozer and the NXT set on my birthday(yes, from the money i get)Im gonna make a autonomous bot from NXT and a IRC(Infra Red Controlled) bot from the dozer(yeah, shure i'm posting a vid.)

[BlueToothKiwi]

Sadly the darker rabbit, Roger died last week (of natural causes). The kids are devastated. :(

[GearThePat]

:(

but clever use of the wheels to keep terrain from getting a lot of contact to the main body of the system. :0

[jimjamkillsnerds]

I have a few questions about the camera (please respond).

Firstly, wow! That is a really good picture for a pda, second, does the k-jam run windows mobile 6? I didn't think it did.

Great creation too by the way.

[BlueToothKiwi]

K-Jam ships with Windows Mobile 5 - thanks for pointing it out. I have updated the description.

[jimjamkillsnerds]

Okay thanks.

But still - I'm getting the kjam and I've read reviews that the camera is fairly crap.

[BlueToothKiwi]

It is - you can see the difference in both video quality and sound quality when the video switch from the camcorder to phone cam.

[MahriNui]

freaking awsome
