A technic pin sorting machine using compressed air for ejecting pins
The pins are feed from the tumbler one by one and dropped on a fast moving conveyor. This ensures a minimum distance between the pins. Next they pass a color senor which measures the color, shape and length of the pin. These measurements are compared to the profiles of all types of pins and scored by similarity. The matching profile gives which output to activated and when to do it. Pins that don't pass the similarity threshold are ignored and drops in the container at the end of the conveyor. - Наука та технологія
I love the way you overcomplicate things using compressed air...
Why do it the simple way, that's no challenge 😀
Wow, this is amazing :D
Wow this is a combination of amazing brainwork and perfect program
Its very easy to do . . . only a lot of money for the parts ;-)
Very cool and well made!
Great work! Keep it up.
Awesome!
Akiyuki: hold my beer.
He can do this smaller and even without mindstorms and compressed air.
I would like to see a time-lapes of all of ypur pins that u own being sorted!
this is one of the best mindstorm models on youtube yet it has hardly any views. youtube search algorithm is poor. Ingenious and elegant. so you multiplex the same motor for two different pins by timing?
If my assumption is correct then why could you not use 1 motor?
1box Shop for all pins
Thanks!
Yes you are correct, one motor controls two ejection nozzles. We tried to use only one motor but the pressure drop in all the tubing was too large.
And the disadvantage of using multiple nozzles per motor is that you have to slow down the pinfeeder so that each pin has the time to travel past all nozzels before you scan the next one.
On this setup we can scan new pins continuously and have them in a ejection queue.
So during the transport of a pin too the later nozzels we can scan a new pin and eject it, if the nozzle is close to the scanner. That is why the most common pins is closest to the sensor.
If you could spare a couple of EVO 3 , and use one motor per nozzle we could manage 5-10pin/sec.
Andreas Nilsson could you please provide a little detail of how the motor turns the air on and off? I cannot see properly but presume you are squashing the rubber tube to stop the air rather than using a lego pneumatic switch?
Nice machine! I'm also building something like this. But i cant get my tracks for the round thing not as nice round as you, so how dit you do that?
This is so dope
cool idea man!!!
where can I get one, or how can I build one?
This is what I need so I can dump all my Lego buckets into it and it sortes into the bins
+Andreas Nilsson Hi I'm interested too! Can I have the basics?
Hi, Andreas
Building a conveyor system now and trying to apply this idea. How does air know when is the right moment to push. What program regulates it? Your answer will be highly appreciated. Thank you
Vad har du för låt i videon
Its awesome
But how does it differnetiate between the long blue pins and the short blue pins? As far as I can tell there's only the colour sensor to sort them.
It is measuring the length of time it reads the colour values and compares it to a database that defines the pieces. A blue return for 5 readings could be a short blue peg and a blue return for 7 readings would be a long peg.
Andrew Firestone And what happens with the old black Pins?
Is the length the dominant value?
pietpiet11639 yes
Well done! But why use compressed air? you could be using the servo's to knock the pieces of the conveyor...
I just liked the idea of using air. Probably a lot simpler with mechanical arms but why take the easy road :-)
Hi do you have the building
I still don't get how pin sorters work
*i need this in my life*
AWESOME GREAT IDEA
Thank you!!
I like what you created here, don't get me wrong, but I do not understand the need for a sortingmachine now that they've added the colours xD
Cool good idea relly brilliant
...good engineering
Great project. I'm building one of these with my 11-year old for a Science Fair. We have the feeder built and are into the code and sorting. No compressed air, we'll have to figure out another option with the tools we have.
+Dave C Nice, please share a picture if you can. How did you solve the pin-ejecting?
Nice
I just love this ! I am currently trying to make a pin sorter myself. Quite hard ! Do you only use color to sort the pins ? I would like to sort the 2 and 3 blue, black and grey pins. I was thinking of the color sensor to do this final job, but my main problem now is how to sort the 1, 2 and 3 heights pins. Thanks for that great machine !
PS : where do you get sooooo many pieces ? Can you buy them by kilo ???
+Romain Schmid I only use the color sensor. Since the speed on the belt is known, the time from the first sensor read and the last gives the length. But using the length and color separate didn't get a good enough result. So we collect 7 variables and an array of how the colorvalue varied while passing the sensor.
These values are compared to predefined pin-profiles and scored according to there difference. the best scoring profile is chosen as the "winner" and ejected at the right collection bin.
And in the case of asymmetrical pins we have two profiles, one for each direction the pin can pass, e.g. is the tow-ball pint traveling with the ball-section first or the pin-section first.
We spend more than a year one this design and we hope that we can do a faster version with the new EV3, but we both have small kids now and there just isn't enough time right now.
+Romain Schmid I bought most parts from the LUGBULK
lan.lego.com/static/build/docs/LEGO_Ambassador_Network_-_The_LEGO_LUGBULK_Program.pdf
But brickling and brickowl are both good sources when you need one piece and plenty of it
Tutorial????😮👍😁😃😙
super gemacht
Amazing. Don't listen to the trolls who aren't getting the big picture.
Kevin Johnson Hello?
Fail 1:36 A black connecter pin falls in the longer blue pin bin.
Its a long black pin, they are sorted together with the blue ones.
Ooooooooooohh.
Wejustmight die 😞🙄😒😒😒😒🙁🙁😯😿
Wejustmight die its true
Wejustmight die actually it probably was a longer bleu pin in black, that's the older version
How does it recognize between the long blue and long yellow pieces ? ; they seem of equal length
Nicolas Fredette it uses a color sensor
I would like links to music??? Andreas Nilsson?
+Thức Anh Sorry for the late reply...
Its Far Away - MK2
cool
COOOOOOL!!!!!!!!!!!!!!!!!!!!!!
where do you get all the mechanical parts like the chains and gears from?
Bricklink.com
the song is far away mk3
Angel The diamond and gold Thank you so much!
I like the music
What is the song used in this video?
Macky Fitzpatrick far away - mk2
can i boy it
how do you all do this kind a mindstorm
Can you English bruh
where can i find the pumps, air cylinders, and hosses?
You can find them on www.bricklink.com och www.brickowl.com
i want instructions!!!
i think that Young love watching how its made :-)
+MultiChannel™ Hehe, sure do. It happens to be my favorite show
+Andreas Nilsson so do i ;)
you should try to make a machine to sort ALL lego pieces, sorted by type, not number. as in 1x3 in a section of their own, all colors mixed.
You can try it too :)
What signal is sending color detector when there is no pin? and what signal when there is black pin?
Im having problem with distinction of these two in similar machine, becouse when there is nothing infornt my color sensor, its sending black color :(
Hi, thats the reason for the yellow brick infront of the sensor. When no pin is present it will show yellow. Good luck with your build
Thx a lot for answer so many years after video premiere :)))
So, this yellow brick raises my next question about those nearly yellow long pins (those for rotating elements, 4th "box" from the left) becouse they are recognized as yellow too :P
If i remember correct you have to look at the RGB values separately. That's especially important for the light-grey vs light-bluish-grey pins.
Ok, but i suppose its impossible in block programing mode (there are available only values from 1 to 6) :P
I guess you programed this sorter in C/C++, am i right?
hur byggde du den?
Många timmars byggande av prototyper och testande.
Har byggt efter egna ideer.
DO A GEAR SORTER
Thumbs up from me!
It is supper!
I suggest removing all the springs from compressor pumps to increase the efficiency.
I tried that, but since 4 of them work together and in 4 different angles the springs cancel eachother out.
Bit they only lasted 10 hours, maybe it would last longer without the springs.
I had to assist with a bicyclepump and 10 plastic bottles as a huge airtank.
@@McKvack2 you mean the batteries lasted 10 hours of continuous operation?
If only you could use solenoids to control the air ejectors...it could be made much faster.
It's like I'm watching How It's Made...
🤩
Good ;)
Like !
que padre
как ето сделать
WTF how did you find all those 5x7 frames? How many do you have?!
Plenty :-)
Lookup lugbulk and join a local LEGO AFOL group if you have a large project and need high quantity of bricks
thanks
At 1:58 you can see sprung pneumatic cylinders which strain the motors compared with the normal ones
Those are pumps, not cylinders. The two XL motors have plenty of torque
.......
What is the motor/air pusher called
To you mean these: ua-cam.com/video/CuW73P5PanM/v-deo.htmlm16s
If so they are motors from LEGO NXT (tinyurl.com/jsngwwy )
what are the motors? are they normal motors with the pneumatic set?
The motors are NXT motors and the "air-valve" is just the hose pressed between two lego pieces.
tinyurl.com/h4uoqjv this is mounted on the motor.
OH NO THE ROBOTS ARE TAKING OVER!
whats the song called ?
Max Monroy far away - mk2
I need this
Feel free to shop around on bricklink and build it :)
👍
Nice to see our 7 year old clip still finding new viewers😀
How it's sorted: Lego pins. 😃
There are so many sorters on UA-cam that focusses on one specific type of bricks at a time, you guys should collaborate by trading ideas.
Really nice machin. Just set you a request on the link below. I'm one of leaders in a Lego-Robot club in Horten, Norway and this invention would have been great fun to build or at least analyse. Good inspiration for First Lego League ideas. And of course the constand need to sort Lego when 12-13 yougsters are building stuff :-)
Good luck with the build. Let me know if you need anything more.
Demo av våran sorteringsmaskin
+Andreas Nilsson Precis som i verkligheten! :D
Det här var väldigt smart!
Kommando Killers saa
Det här är fantastiskt!!
Good jop m8
wow inte illa väldigt coolt!
헐.......
Music name?
MK2 - Far Away
i dont hink the programming for that isnt so hard
1:36 black pin in blue
Nice catch
idk how it works but its boss
+minecraft maniac it says on the description
Wtf ;)))))) you are a geniuss man omg with air presure shit
if you took the damm springs off the pumps they would be a lot better -.-
This could've been a lot simpler
First, thanks for commenting.
My purpose was to make use of the technique and not to make it as simple as possible.
How would you have done it?
I will pick up this project in a month or two and make another machine which uses some other technique.
1:36 :)
ipadize it's the black older version of that pin, it's supposed to go there
On 1:37 kame à black pin in the rong place
And 1:42
It's right, old style of 3 long pins were black
444 subs!
1:37 wrong one!! 😂
Also 1:55
melvin geerdink it was a 3 hole long connector, but black. Please watch the video before you make dumb comments
Needs more unnecessary dubstep like all the other Lego videos.
Fake
Unoriginal music, dislike
