Computer controlled Lego elevator V2

[EroSeninLucas]

cara fiquei impressionado! meus sinceros parabéns!

E eu que pensava que brincava de lego montando carrinhos....

como posso fazer um????

[TheJulioG6]

wow melhor tipo de LEGO que ja vi no mundo

[ChicoDaRave]

Muito obrigado amigo! E isto é APENAS LEGO comum!

[Potew]

Esse motorzinho e esse sensor vc conseguiu aonde? É uma peça de lego adaptada? Estou pensando em fazer um elevador usando algum microcontrolador, tem um RCX que deve servir, mas é caro, talvez use um PIC. Tenho muito o que aprender ainda =P

[ChicoDaRave]

@Potew O motor é de Lego mesmo, porém ele estragou e tive que fazer um conserto tipo "super gambiarra" nele, mas originalmente era Lego mesmo... o sensor é apenas um fotodiodo que encaixei no furo da peça, bem como o LED vermelho do outro lado. Sim, certamente você consegue fazer com PIC e com várias funções, mas será necessário conhecimento de eletrônica e programação.

[ChicoDaRave]

@Potew Não tem manivela. Usei apenas um extensor de eixo, um eixo longo e uma polia grande (6 furos), a polia na realidade não tem função de movimento, serve apenas para o computador saber onde o elevador está e então controlar o motor. O fio/cabo do carro vai preso direto ao eixo. O modelo antigo usava algumas engrenagens,mas para este resolvi usar direto a fim de ter mais velocidade no movimento.

Legal

Parabens

Você usou alguma espécie de microcontrolador? Ou está somente usando a porta do PC?

[]'s

[ChicoDaRave]

Obrigado...

Neste projeto não usei nenhum microcontrolador, apenas um pequeno circuito de driver para o motor, que vai conectado diretamente a porta paralela do PC.

Cool

[narnia0100]

How come in the distance to ground test how come it says 13,411 CM instead of 13.411 CM? How come theres a comma instead of a period?

[ChicoDaRave]

I'm in Brazil... in Brazil , is . and . is , .... inverse of your country.

Ex: 1,5 is one and half

[blueberry0700]

it was awright

[tamerius1]

lol, the guy must go out very quickly

[poipoipoihuijvff]

Let there be a power fail!!! I want to see that Lego man bleed!!! >:) lolz that's cool

[ChicoDaRave]

He is VERY luck! If power fails nothing happens! =D

Elevator just stops.

[TechyWatcher]

Its Awesomly good! 5 *

[vanderauweraw]

wow!

COOL! =)

[diegodaudt]

Legal! Que software e ese?

[ChicoDaRave]

Esse software eu fiz especialmente pro elevador, a principio não tem nome.

[skaterjoe12345]

NICE

[ChicoDaRave]

Thanks.

[narutodude0909]

Hello! I love ur creation and could you plz tell me how to programm it.

[ChicoDaRave]

Thanks.

You will need eletronics and programming skills to make this.

I used a lego perforated piece to obstruct a led light to a photo diode, the computer counts every time this happens to know the relative car position. Counting this from ground to last floor and dividing by number of floors you will know the size of each floor in number of obstructions. I can give you some specific directions as you need in your "journey".

[halomaster1177]

Did u use the parallel port?

[ChicoDaRave]

Just the good and old parallel port! + some components connected to it to deal with motor, led and sensor.

[jchaytor]

was this hard? lol

[ChicoDaRave]

Not really... the hardest part was the computer application ;)

[Superdreamkilla]

Nice Job! I'm making my own elevator for a Death Star and I have a question. Why do you use a sensor to count rotation? Mindstorms block can count motor revolutions and sensor only duplicates this process. Relative position can be counted just the same.

[ChicoDaRave]

Thanks! Sorry, I dont know the block you are talking about. Here lego pieces are very expensive and hard to find, so I do the way I can, mine is a simple reduced lego motor (it was burnt, so I changed its motor to one smaller, very sad!), To avoid one sensor per floor I put a led and a photo-diode on the motor. Also to avoid one more sensor to top or bottom of shaft, I coded the program to always go bottom when closed. What is Death Star?

[StarRose08]

thats so cool

[ChicoDaRave]

Thanks ;)

[runefreak3]

could u tell us how to make it plz plz plz

it was ma though if u do i will really appreatiate it

[ChicoDaRave]

Hello Runefreak3... the project is very simple, first you need to build the lego elevator, for the sensor I used a perforated lego sheave/pulley to obstruct the led light pointed to a photo-diode which is connected to PC LPT port with a custom application, also a H-Bridge to control the motor. You just need to count how many times the light is obstructed to know the relative position of the car. I hope this helps. Thanks for posting.

[forthfriend]

Love It! Could you post a software download though? Or, could you direct me to a tutorial on programming? Thank you!

[ChicoDaRave]

Thank you!

My software is very specific for my elevator eletronic... but if you have knowledge in programming and know how to use the parallel port, it would not be very hard.

Thanks for the post!

[LegoFan970]

good job! the programming was awesome

[ChicoDaRave]

Thank you!

[master74200]

that's one prett awesome elevator.

i doubt they'll be using these on 30 floor office buildings though :p

[ChicoDaRave]

Thanks. They wont use, the system is faulty yet, but adding more 2 or 3 sensors could be very secure.

[master74200]

yea, but i meant the real office thing..

[LumPeyCusTerEd]

where did you get that

[ChicoDaRave]

Just Lego pieces, some electronic components, and a bit of programming. Thanks.

[boerdan2009]

pro where u buy it?

[ChicoDaRave]

Hello, I dont understood your question, but, everything was designed by me, including the lego elevator, circuitry and software, I bought only the lego pieces and eletronic components.

[Rymac91]

how does it keep from sticking to the sides of the elevator shaft?

[ChicoDaRave]

Nothing in special, I just pushed a bit when mounting the shaft and worked very well as you could see. Thanks for your post.

[steeeven1]

i take it you made that program, which controls the elevator.

neat ^^

[ChicoDaRave]

Thats right, I made everything (except, of course, lego pieces and eletronic components).

Thanks for your post.

[Antilagger666]

can you make it fall? :P

[ChicoDaRave]

Without mechanical modifications or an accident, no!

[jinkazama496]

accurate ^^
