robotizing your LEGO TECHNIC creations with NXT & IR-Link

[KilledCookie]

what is the distance that the sensor will work on? I thought this can be used to remote control it.

[corotor12345]

right now i'm working on an idea. the idea is to use the IR remote to send instructions to the NXT, the intelligent brick would then act as a bridge and regulate the remote's signal, passing it onto the IR reciever through the IR sensor. the concept is to be used with an electronic stability control, an ABS, and a traction control. so if i push the trottle too hard, it lowers my signal a bit in order to mainatin traction. or if i break, to pulse the breaks. and so on and so forth

Cool! Some models I just can't get a motor on...

[crossbow711]

that wont work with the lego technic dirt bike. but nice job!

[Victor112007]

good

[pietzeekoe]

is it better to have 2 xl motors or 1 normal and 1 xl?

[billyboy385]

wow, nice!

[mavamaarten]

hey, where can you get the PF-Motors without the whole bulldozer ???

[BlueToothKiwi]

LEGO Shop @ home web site.

[mavamaarten]

OK thanx !

[bazmarc]

I just got my IRLINK sensor,,, fantastic ,,, still have to experiment with the RCX BLOCK that will give so much more possibility to our robots .. all i need now is time :)

[nutsforlego]

that is the best little buggy ive seen

[WildernessSurvivor]

will the nxt-g 1.1 have the Pf motor block?

Plus, the other things that comewith the new lego technic pack the 2 recievers and remote.

what do the recievers do? and how much do the lego technic products that have the new motors cost? im guessing the bulldozer has the most motors. very nice video :)

(1) The Motor block does not come with NXT G - you can download it from the HiTechnic web site

(2) You can get two PF XL motors and two PF normal motors plus two receivers with the LEGO bulldozer (8275)

hey dude what happed to your screen!?

[kapu995]

Hey! Where did you get those motors they dont come with nxt kit or does it? I dont have one, yet.

[BlueToothKiwi]

Hi Kapu995,

Right now the PF motors ship with the LEGO® Creator Dinosaur, LEGO® creator Ferris Wheel and of course the incredible LEGO® TECHNIC Bulldozer 8275. The Bulldozer comes with four PF motors in total, two receivers, and one transmitter (or Remote) - but in this video, the remote was never used - the robot was totally autonomous.

[Rikitheshadow]

Got to ask a question. So are the extra PF motors ran by a seperate battery pack and infared system? And then the NXT uses its infared sensor to communicate with the extra PF motors?

Sorry never seen these PF motors....

[BlueToothKiwi]

Hey Rikitheshadow,

Yeap - you are pretty spot on - The PF motor needs a separate Power supply at the moment.

And the IR-Link (from HiTechnic)plugs into one of the ports in NXT - thus turing your NXT into a InfraRed remote!

buddy can you make like a drifting car out of legos and motorize it

[BlueToothKiwi]

Hi AltF4ESCICON. I dont see why not. Why dont you send me a link to a drifting car you have in mind - and I will see what we can do
