NXT Line follower and obstacle detection II

[ObviouslyEequalsMC2]

My FLL team built a thing just like this, exept without obstical detection.

[Furiadecoachas]

Es un lego!!!! eso le resta credito :(

[WhipTingz]

It's really slow.. check out mine that I built in grade 10, just type in johnt20 and you'll find it.

[Tocinator]

Usen la función steer de la clase Pilot! eso les permite girar mientras avanzan.. el robot andaría mucho más rápido

[Daniel1234ification1]

it goes quite slowly



[DanBoy2DaMaxXx]

Hey guys - just an advice from germany ;)

your robot would go much faster if you'd tell hin to turn 'til he reaches the white edge AGAIN! So if hes at the edge of the black line - turn over the black till he reaches white again ==> now it can run a little longer ;)

cheers

Look guys, in Pixar's "Walle" the robots on the axium had these lego NXT line detectors WITHOUT the obstacle detector. Soon they decided to override the lines and go over them and soon crashed into some other robot.

[bttfjunkierc]

Japanese can build any thing! 

[uberdragonbreeze]

that's great! Based on what I see here, i'm going to try to make my own

what i was wondering is, how do you make it turn in the correct direction?

[pj0ta09]

@uberdragonbreeze, you can check the java source code on the Website listed on video's information.

The way we made the robot turns the correct side is turning both sides: first a little to the right, then a little to the left, then a little+1 to the right, a little+1 to the left and go on. When the robot finds black line it just goes straight.

[cyberbuddy777]

@pj0ta09 you're a genius

[frasercorey]

@uberdragonbreeze if statements about the sensor or sensors followed by some then statement that controls the motors, I'm assuming you control the direction these move by increasing motor speed on one wheel? They have two separate motors? Can someone confirm this

thanks

[ssawan23]

Check out mine robo...its using simple bredbord circuit but ..smart...!!

[MySAMJ]

senjor usted puede ser tan amable de enviar me el codico q uso para programarlo... porq mi papa me compro uno de esos yo tambien kiero programar uno :(

[polino247]

Dude, that is Sooo coool, U rock!!!!!

bravissimo!!!

[vinny9er]

k pretty kool

[MozartJunior22]

Bad line following. But Like on 0:21 music

[aimiel13]

inaano ka??



[sirpau1]

It would be a lot more interesting if it found it's way around the obstacle! A simple distance check is easy :) For a university project, it should at least be faster.

[MrNinjaboy100]

mine is faster!!!

[getl4id]

Haha if it would foundation its way around the obstacle and back to the path it wo

[AlCoholic162]

lol I build that in my 3rd grade and it was much much faster and could do much more than this thing

[salildd]

ur robot's speed sucks...bigtime.......

[fuzzywuzums]

Are they speaking italian?

[iSkyProducciones]

@fuzzywuzums spanish

[Danieltronico]

Pueden decir como hacer el line follower

[denkhak]

alabalooba gwa tiya HAHA LoL

[hechod23]

lol...the music

[Majorbud]

sweet

should add some programming in to resolve the obstacle in front of it if its possible for it do resolve the item in question at all.

Hell i'd just make it back up 3 inches, spin 180 degrees and travel in 1/2" sweeping segments until it detected the line again.

How do you Program your NXT Line follower and obstacle detection II

[spaceking776]

firstly u need light sensor fork.

[rotjesenmatjes]

Spanish!?

lol nice thingy

[Toxighh]

muy bien

but you must be programm it faster

[TomProductionsGO]

its realy good

did u bild it yourself

you should try ad make it go faster

[crisofilax]

La imagen que tenéis es impresionante!! vaya pisote eh!, cuando tenía 19 años hice eso con una plaquita analógica y realmente iba mucho mejor que el vuestro... Ánimo! que los 32 bits del NXT dan para mucho más!! Con dos sensores de luz conseguiríais mucha más velocidad porque la máquina podría imaginarse por qué lado de la línea se ha salido...

[Stuck2Life]

Good try but you should really make it go faster. I use RCX and that has much faster processing and line following.,

[Paulendy]

you should try and make it so it can sense the line faster so it can go around corners faster.

[shawnnaruto121]

you should program ur bot to have a reaction when it detects something like go back to where it started. But nice robot anewaz =D
