Micro line following robot

[Mr20001214]

where can i buy this in singapore

[ntipouan]

When it comes to a Y-line how does it choose where to go ? Is it random ?

[AllGoodNamesGoneFUUU]

@ntipouan It's programmed so that whenever a light sensor picks up a white colour (track is blacK), the robot turns to the left until its hits a black part. A black colour tells the robot to head straight. Thats why it takes the left turn whenever it meets a Y-line :D

[ntipouan]

@AllGoodNamesGoneFUUU Ah, an if-then-else structure :) Thanks !

[sorobuddie1]

wall-e...

m-o

[Manga1Anime2]

Sweet, so where am I buying mine at?

[arky3000]

this is gonna be weird, but im impressed of the slight chaoticness of the lines he made.... the robot is cool too :)

[nosefries]

This is not real. It's a photoshopped video.

[mattyh099]

@nosefries idiot... it is real.

[RunOrDie77]

@nosefries stiupid idiot {all idiots sayy:photoshop/fake }fml

[FutureInventions]

@nosefries Photoshopped video? Really? XD

[WaterPocket]

How do they choose at a forkroad? Just by chance?

[Interpr3ter]

jeah but...WILL IT BLEND?? :D

[crazyyella]

I'm totally waiting for someone to comment that this would be much better if they were solar powered.

[xynth101088]

@crazyyella Well you know. Considering it's size if it ran off solar energy that would be quite the achievement.

[Kaeseworstiger]

i would call him Wall-E ;)

[pasinduranjula]

great



[bluetube231]

did you buy this?,

if so where can i get one?

[fenix155]

D:

[theparodymonster1]

but will it blend?

[ThibautVDP]

@theparodymonster1 wha do you guys always mean with that?

[huuua2]

@theparodymonster1 "That is the question!"

[ThePoseidon211]

it would go but one way?

[grenouil1970]

:o)

Bonne journée

[u2beegees]

can you make the lines follow the robot?

[mikeflash2160]

fill in the paper with black lines and see what happens XDDDD

[eddymierda]

wats?



[CatastrophicLlama]

you all smell

[laurie121212]

There is also a bug that you can get to follow the line of a bic pen. It's all because the pen has the scent of the bug's hormones. This robot doesn't seem impressive at all.

[ramiister01]

Hi! This is a really cool bot, congrats...

Can you give me some tips of how can I build one myself?

[NAWRARESNAW]

I have one but its a tank

[dudealive1]

one day with a few modifications our evrreyday cars will have an auto pilot system using the same sort of technology

[AndrewJBright]

is this DIY or pre made?

[jackbenhamFUCKYEAH]

i remember those, had one like 9 years ago (well i think) but mine was really big and come to think about it very pointless

[fishluva1]

very nice but the hater in me wants to say that those robots are quite simple to make in 7th grade we made those but they were voice activated

[zppz]

@fishluva1 and were they smaller than a ping-pong ball?

[Shiroblack]

Future train!

[kairon156]

@Shiroblack until someone takes out a can of whiteout/white paint and covers/changes the direction of the black line.

[dogdude84]

Uhh...it just followed the same route.

[GameNinja13]

Awesomeness

You can make these from kits stilll right?

[Mobiandevil334]

lol :3

[happygamestvfun1]

i made one of these but it malfunctioned and crased and blew up

[SatoTM2]

how do line follow robots pick at road switches?.. n acute angles, road gaps and inverse lines?.. i want line following robots after watching wall-e the zillionst time

[shoyur]

@SatoTM2 it works exactly like a cd-rom lens, its 3 eyes, comparing the darkness

ex: eye1 & 2 = dark, eye 3 = white, then you must turn a bit to left, at a cross section, or Y split, it simply sees 3x dark and goes straight cause it doesnt see white, so then its just random, cause before it stop turning right or left at this point, MAYBE you were a bit more left or bit more right...

[xato909]

poor robot, it so confused :(

[SatoTM2]

OR robot following the micro line

=D?

[0virus00]

how does it "decide if its going left or right at a diversion??

[uluis]

Does it follow the line, or the color black? If it follows black, then what would happen if you colored the whole paper black?

[lolColin21]

i have the bigger one

[VipSwaT]

es un genio ese bichito quiero uno ! donde lo cazo ?

[jdsnanuk]

Very cool!

[chrisvanhoorn]

I think it just contains a magnet so it follows the metal trail underneath the paper, and the motor in the bot does the rest :) 

[iwan0t0smith]

@chrisvanhoorn If I were to make one of these I'd use a laser and and some light Dependant resistors to control the speed of each motor

[faturd95]

Oh let's see now GAY

[TedHeadxoxo]

I have one of those in my tech class, its the coolest thing ever.

[vengpjer]

haha he has a black colour sensor in just like mindstorm robot.its nice btw.cute little thingy

[candileeable]

@WilliamUzumaki99

that's because you can't see them. i mean that the robot is fat and the wheels are under so you can't see them.

[shuhadabasheer]

this is stupid!

[JonAxDrayda]

@shuhadabasheer If it is, then why did you even post a comment in the first place? I think it's nifty.

[sobeita]

I have an idea... use the inverse of a computer mouse, the kind with a mouse ball. Take one apart if you don't know the mechanism. Four rollers sit above the wheel, and instead of sensing dx and dy, they would control A[x] and A[y]. Then for balance, it would need to rest on two free wheels (like the swiveling wheels on a shopping cart.)

Does this sound interesting?

[1888junkteam]

excellent work!

[NickBell10]

awesome i am goingt o use mine to watch my house when i am away on vacation, i am going to have my laptop rigged onto it with its webcam on and webcam linked to a website :) and it will keep going

[RockyRoadRocks101]

do u guys see the wheels underneath :P

[WilliamUzumaki99]

yeah. if there's no wheels, it can't move

[dangilostthegame]

that's really fast compare to others i say he programmed it to go on that line without sensing it

[wepootheuser]

@dangilostthegame You know, what you're suggesting would be a good deal better than if it did just follow a line.

Imagine the accuracy needed in the hardware to ensure it moved the same as the line was drawn.

[DeathSlayer2]

that would take soooo long to program and if that's the case why does it miss out half the track?

[Lightbeam112]

Maybe it could have an electromagnet underneath it that works only when switch on.

[1elektro1]

i guess it have light sensor so it track the black line.

[vdub350]

It usually is, probably an IR light and sensor.

[Th1s1sMyAcc0untNam3]

no its no maget it rly tracks the line

[darionmograine]

This is definitely not the smallest, I have seen smaller in kids toys, but its a cool lil toy!

I bought one from Toys'R'Us XD

[swanbrown]

you may want to check the post date...3 years ago

[24Tributer]

i could trick the thing

easily

[Alex90652]

iv seen those things at toy stores but i never did figure out how they work :/

[Schwarzer0Ritter]

It has two sensors on the bottom. With that it can see if it is on the line.

[Alex90652]

ohhhh thanx =D

[Archanox88]

Magnet?

[audax5435]

no magnet.. it has sensors on the bottom to see the lines..

[andraws11]

awesome

[georgedude77]

sweeeet!

[strgzr53]

i got to say very well executed 5/5

[mcebro07]

well done 5/5

[7AuSrUBoY7]

who cares?

[dankimxdd]

easy theres a snesor on the botem when it ses white it turns thats about it

[finalconsecration]

A snesor on the botem?

NO WAY, dude!!

[7AuSrUBoY7]

improve your english please.

[asaguda]

This doesn't look like a 'line following robot'. It swerves left and right constantly, meaning it looks, to me, like a 'white paper avoiding robot'. :D

[djdakki]

it looks right and left so it knows if the black line goes right or left. Duhhhhh.

If you would put like 3 sensors in a row, it wouldnt nead to that, becus it sees the black line, and the white shit.

[tetramincolor2000]

@asaguda lmao

[HomerStolls]

@asaguda i agree

[theparodymonster1]

@asaguda *turns left, notices white paper*: AAHH!!! OH MY GOD!! *turns right and notices white paper:*AAHH!! OH MY GOD!!* '

and so on

[TheBetterGamer]

Damn advertisement on the right!!!

You load so slowly and make me suffer by having a laggy video!!!!

[drakeodude12]

everybody should know that this is out of a toy it vibrates and flashes lights i should know i have one!!!!

[ddrmaxman]

This will never be how cars work unfortunatey. 1 it would take too long and it would be too expensive. not only would cars need to be made but every road in the world would need to be updated and recolored, and everyone would need to buy that same new car because the cars could only detect the lines not where old cars are.

[zezba9000]

Where did you get that?? in Japan?

[denha]

It produced it for myself.

[zezba9000]

Thats totally cool.. Did you program the thing yourself? If you did, what language did you use?

Im a 3D computer programmer, but dont know much about the hardware side of things.

[rakker614]

@denha i want one!

[critx001]

@zezba9000 he said it's made in china :D

[zezba9000]

@critx001 lol figures i'd miss that.

[AunShovah]

IN japan

heart surgeon

number 1

steady hand

[easytouch12]

what is that :O

[sanders924]

whats the point?

[360983]

Pretty sweet!

[ZapotecMaster]

walle!

[chutit27]

haha it just got stuck in the circle

[ddrmaxman]

Did anyone notice that it just follows the exact same route

[tsiaxiras]

no we dind't........... -_-

[demonicowl]

@ddrmaxman I think that's because he made it alternate it's choice when it comes to a fork in the road, ie it will first chose the left path and then the right and then the left again...

[fuzzet126]

@ddrmaxman thats sorta the point

[ddrmaxman]

@fuzzet126 not really. it should alternate between roads. The drawing DOES have multiple branching points.

[jadenedaj]

@ddrmaxman Dude, it doesn't go the same route exactly- the first time it goes all the way down the bottom left, and the second and third time it goes on the more inner-track.

[ddrmaxman]

@jadenedaj and from there on will stay in the inner-track.

[jadenedaj]

@ddrmaxman Not necessarily. I see no reason to think it might not change course. 15 seconds/two times around the track is hardly a long enough time to determine if its stuck in that course.

[ddrmaxman]

@561inurface wrong person. lol you want to reply to the person above me.

[561inurface]

@ddrmaxman w8 wat?

[ddrmaxman]

@561inurface you replied to me with something that should have need told to asaguda.

[561inurface]

@ddrmaxman ya because your comment sounded like you were saying that the robot is not following the line but just going by a pre programmed route

[ddrmaxman]

@561inurface I'm not doubting that it's following the lines, I'm saying that it seems to lack the ability to randomize the path it takes.

[zetonium]

this is the future of us driving cars without actually "driving" them, our cars will follow those lines and it will produce less car accidents.  (My opinion)

[spiceitupbitch]

My mom is excited for it. She hates driving =P

[Nanowarex]

Untill somone paints a new ling going into a tree.

[deejaypile]

where did you get that wowWOWOWOWOWOWOw

[robot797]

same

[puzzlepiratess]

nothing special? you try making something that follows lines, pretty good i think :D

[JamieLProductions]

I want one!

[quesoman100]

boring!

[Diehighpie]

Nothing special..

[michelfijn]

Muhh.

left-right-left-right

boring!

circle!

[IFlyHigh32]

i made 1 alittle bigger, circuit boards = fun

[Trackstar22190]

The big blue thing behind the small robot is a larger line following robot. It looks like the infrared light sensor was taken off and combined with a small motor in part of the original casing to make this robot

[slinkyskunk]

How did you make it so small?

[hithonrx7]

How do u get one!

[myrice101]

epic win! i need one

[TheBabygirloflove]

my bro gave me one when i was 5 and it went out of cotrol

[kathynguyen129]

my mom bought me one at the mall when i was small and there where these puzzle pieces the robot was sopposed to follow andot would go around and around

[MSfingerboarder]

my mom got me one of those to!!!!

[313Today]

why am i watching this :|

[Flashlight1996]

Cause you love pacman?

[SmallsCantShuffle]

This Reminds Me Of Pac-Man

[PotasoSeymore]

How much money are these? They are cool

[goofywilly]

Yes... ive seen many "line following" robots and you are correct....this is the smallest one ive seen so far...... There was a guy in Guam that had built one

out of a piece of rice but it wouldnt move so good... he was hoping the power of faith would move it for him but all it would do was flip around on the hot skillet and not follow the lil lines (no motor) ! JUST A PIECE OF RICE ON A HOT SKILLET :O

[MizyMooLikesTwilight]

Lmao!

[kdudelol]

i want it

[dragonfire839]

arduino

[Jbob98theoriginal]

that's cute...

[ningaturtle999]

programmed?

[thebigbadgun]

it might have a small stick thing at the bottom

[sdvman10]

Its just like how lego mindstorms can move on a line. there is a color sensor on the bottom, and when it senses that the color changes, it moves left or right to stay on the line

[AYYANZAIN]

muho hahaha!

[galinuas]

The liens are special things that the vehicle moves on- it's not grooves or anything of that type. It's a very common children's toy in America.

[egbob3]

this is a kids toy in america

[HIIMRAVI2]

maybe its just following a groove.....

[superafterburner]

It's following the darkness of the line. It has a light sensor on the bottom to detect the line's presence and steers left or right to stay over the line.

[ZeBoxx]

if it's the typical toy, then it has two very simple photoresistors on the bottom near the center. If the left one receives more light (reflected by the white paper), resistance goes down, and more power goes to the left wheel motor. This causes the little robot to steer right. Ditto on the other side. That way it 'follows the line', but only as a consequence of the above behavior. It's pretty simple to build. The more complex electronics inside are just to save energy.

[roxel6]

did u make that urself?

[yullu65]

I want one!!

and when i get it i will make it follow the lines of a penis!

[Florjan57]

ROFL

I WAS THINKING THE SAME THING

or make it follow into a room or at my cat so my cat freaks out xD

[CalebHayesInc]

that's not straight at all

[naszwan]

hmmm...

[WrongPersonLmao]

i want one

[lorekingwn]

Are the lines made with special drawing tools or it'll just work with any thick lines? That's awesome!

[HyperMonkey07]

It still amazes me at how quick it can process the information it's receiving and how quick it can travel!

[pookaguy1]

Cool.

[iSkateEuclid]

its magnets thats why it was wigling

[n2thee]

No, it's not because of magnets.

For each time it turn to a side and then to the other he finds out that he is looking at the white paper and not the black line. Therefor activates the other motor, so he goes the other way until he reaches the white paper again, and reapeats this.

And in other comments about choosing of lines is completely random. This choosen by the way he is turning at that moment and hit the white paper. If the ground was all black, he would spin in circles.

[albettylillee]

dumb

[Singer90]

i just can't understand...how can he choose which line going through when there is a fork?

[Calvinator321123]

I think those Lines were drawings

[ujmi]

These are often simply programmed to sense the change in light reflected from the surface to follow a dark line.

Therefore, based on this simple algo (which I believe is also in use here) it is simply following whatever seems to be of the highest contrast amongst the two.
