Lego Mindstorms NXT Car Four Wheel Drive

[Redskull1312]

whats the mechanism ?

[mindstormsuser]

what good will it do if it only has a flexible chassis

[MrTpengineer]

@mindstormsuser I don't think it has a flexible chasis, if you look close enough you can see that it's the servo that's wobbling, but that's normal for thoes.

[hockeymann3232]

show how to make it plz!

[1224steve]

can it pull anythiny or off road its got to do sumthin good job also

[kittykrazy1]

cool!

[DaNsEb1337]

nice garage band music!!

:D

[finneykris]

very good but im making one wich has 2 differentials 4 wd andthe front wheels actually turn rather that half of the car to make the car go round corners etc

[timlyo]

if it's four wheel drive then how have you added a difrential

[chazzers77]

He probably used 2

[XxXxFREAKxXxX1]

Do you have an account on NXTlog? If yes, please tell me your name!

Mine is imtoofastforyou1!!

[sholtob]

i have an acount on nxtlog with the same name as on here, and i think this is made by natonx, or the first one iis

[XxXxFREAKxXxX1]

WOW really amazing!!

[BFLWProductions]

this is amazing

[DeidaraR0X]

wow amazing!! this is an incredible robot!

[AUDIRS8FAN]

thats an very good idea

only parts by NXT ???

[leonlixinfong]

What was that ultrasonic sensor for? useless

[topitapi]

Stupid. He uses it for spotting obstacles, didnt ya' know???

[djdakki]

Omg... It sends soundwaves to make a 3d thingy for itself, so you can adjust like, stop or turn, or go back if you come nearer then 5Meter to an object, or 30cm ;)

[RoboticNerd150]

How did you create the differencal for the 4 wheel drive? With that style of steering it would of slid alot without one.

[lee1vs1wall]

I think he only put motors on two wheels

[MC3craze]

So it works like a motorcycle? (The steering)

[bordem767]

did you make this song in garage band!!! hahah but nice work i suck at nxt

[jepdiniz2]

i am working on something like this but on 4X4 i wil, post a vid soon

[jinimama]

Does it have Differential??

[boobear825]

movie is awsome doods...!

[gmolica]

how do u do that

[SingularlyDatarific]

a vague understanding of construction and engineering, about 250 dollars to buy the set, and a bit of inspiration and genius cooked in to create something like this.

[viki530gurl]

how about mario kart mindstorms

[blackcompe]

That is the best thing ever! I love RC cars and I am a programmer. I'll to get one of those kits and build something in my spare time.

[iHacker2000]

How do you do it, can you post the LDD (Lego Digital Disigner) Model and the software so we can build it too.

[westsidewindsor707]

u shud make da same one but wit four wheel steering dat b cool

[alarmclock55]

which is better the nxt of the rcx?

[WoAzMM]

NXT

[sycmuzak]

NXT, EASY!

[applefan2411]

NXT

[granturismo413]

i recently made a lego 4 wheel drive lego car

but untill i get lego mind storms ill motorize it

[fireworktiger]

you controled it with your phone did you ??

[evilmunchkin366731]

nice design, i might use the spltit chassis on mine the next time i make a vehicle bot

[smartbotX]

you also need the centre unit to control it

[danbmx14]

dose it come with the software.

[DellInspiron56798723]

You bin at Garageband again!

[Oleg114208]

how much do they cost any1 know?

[Gjallarhorn00]

From $250 and up.

[WilliamRLBaker]

REALLY expensive its by far cheaper to just go buy a large variety of lego sets of different kinds, by your own motors high powered ones at that your own electronics...ect you'll pay less and have many many many many more options the only problem is the programming its much harder on your own then with the software you get with these.

[jordan59961]

he made you cant buy it!!!

[SPACEDMADNESS42]

nice!

[zergling999]

easy, just push it backwards

[thetman22]

i cant get mine to back up when somethings in his way how do i do this

[sarolikia]

put a bumper with a touch sensor to tell to motors to go in revers it its pushed in. or use ur ultrasonic sensor to tell ur bot that if it starts getting to close to something slow down and turn according to ur settings left or right. if u want to get more complicated have it calculate if it can make the turn first and if it cant back up then turn or turn while backing up.

[evilmunchkin366731]

i think he did put the ultrasonic sensor on the second time

[airkraft13]

nice steering. on my NXT Rover, i used rack and pinion steering, but i never thought of doing it ur way.good video! for the bt controll, did you write a program using NXT-G, or did you use the mobile application from lego? I used the mobile application for my video!you can c my NXT rover video on my profle, or read more on the design at the link on my profile

Yours,

Airkraft-NXT

[legonoitall]

stay with rack in piniton cause the whole chassis slides when it turns on this car. and it cooler if you have the power to turn the pinion

[nkbelge]

çok matah bir şey değil ama yinede hiçyotan iyidir

[lassin1234]

that is WEAK thing... try make it stronger...

[tsanalp]

I designed one like you wrote. Check the video response.

[Piwarrior]

by the way everyone, lego minstorms 2.0 came with a differential piece, i imagine it would be quite hard to make one out od lego pieces.

[Piwarrior]

you used a differential right? cause i dont think those could work without one at least

[coolcam16]

Did you make that song on garage band? I love garage band i reconized the sounds from it!!!

[acekingie]

sweet

[perryman333]

put a plastic toy truck body on that thing!

that would be cool. awsome dude

[bulzanstefan]

Super! do you have a plan of building the first car? Something like a sketch.

[SteveWho]

Ahh you can do better haha.

I made a 4 wheel drive, with the steering controlled inversely front and rear at the wheels, kind of like how the warthog in halo works. Only problem is i made it with mindstorm, so it was fully autonomous, not R/C, i geuss NXT is R/C.

good job tho

[SuperWizTech]

@SteveWho if u have bluetooth on your computer u can download the bluetooth remote control and u can control it like an r/c from a computer. email if u want the link

[Littlepetslinki]

@SteveWho nxt can be fully auto or RC :D

good job though :)

[ImOkayNowTrustMe]

It's doing amazing!!!!!!!!

[PeregrinusFalco]

Pretty cool. This type of steering I know as articulated steering and we even have a big 4X4 articulated tractor with duals on each axle. Also, so that you car will turn smoother you could put a differential in each axle but with LEGO gears that would probably be quite challenging.

[octanetripledax]

right now i am working on a car that has four wheel drive using only one motor....but right now i am figuring out how to make that possible without a universal joint. pretty cool car!

[Frederickpou]

magic? no it's a lego!

[OmegaSM]

now this is better....add some bigfoot wheels in....it would be awesome!

[mvpfame]

wow, this is why I want to be an engineer!

[patopop007]

cool man"!

[petem1989]

Oops- wasn't looking and posted this on the wrong vid! meant to slag off one of those annoying 'post this to 10 people or bad stuff will happen' type things apologies!

[miss2jeffers3is4evil]

shutup

[mixxyang]

try to creat several of those attach to each other and make a snake

[UAL3422]

Nice. 2 Innovations. One of the car, and the GarageBand you used to make the soundtrack. Good job on both of them!

[megatank28]

cool man

[vadim192]

SICK!

[zanders37]

very innovative

[Chineseteam]

Where an I find the white box? The one on the car, looks like a player. What's that?

[richrobotthoughts]

It is a Lego Mindstorms NXT Robot Kit available from Lego
