Four Lego Delta Robots

[tundernerd]

Great work! How did you calculate the position of the "hand"?

[MagicDom98]

COOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOOOOOOOOOOOOOOOOOOOOOOOOOOOOO­OOL!!!!!



[QuebecoisSti]

what an AWESOME job you did!!!

how much it cost for everything ? it must be alot ?!

[CrazedPickle88]

I'm licking a sugar cube : )

THE ABBOGEL



[MangaMonsta]

That's awesome!

[theonlyshep]

@Dudeofmanyhobbies there are 22 motors total. It's hard to keep them quiet

[Rakiteer]

Hey Shep, awesome inspirational project. I had a question. How did you get 120 degree angles between the motors on the upper delta and universal joints of the gripper delta? Did you use a certain less known Lego piece or do you have a trick using ordinary more common pieces?

I'm a mechanical engineering student from Jordan, and I was planning on doing a similar project with the robotics club at my university. Delta robots are awesome^^.

[MONKEYJAW89]

awesome

[martinloo]

Now if it can only help me to sort out all the rest of my Lego pieces

[soxgreen]

thanks for answering. i am in a "paralysis option" betwen wich of those two engineers i gonna apply, and is nice to understand better the applications

[soxgreen]

impressive! congratulations i always wanted to now if this field - robotics - is part of electronic engineer or mechanical, can you tell me?

[theonlyshep]

@soxgreen I am a Mechanical Engineer, but either is applicable

@theonlyshep missed one red at 0:54

[AV3NG3R00]

@soxgreen

Mechatronics would be closest...

[gladthatdosisdead]

Needs more turrets in need of redemption.

[carzzzz9999]

you are amazing with lego!!!, a very impressive creation!, i really like the programing.

Hope you continue to build new and impressive creations.

[Zemnmez]

Incredible contraption, but it seems the movement time is relatively lengthy.

From that position, it looks almost like you could use the arms to just flick the legos into the correct bays.

[cyrre]

One person did not have lego as a child ;)

[fmmjqtft1]

Amazing, but why can't it just use a single, wider conveyor belt instead? That way each flex-picker would have to access a complete area of points instead of just two line segments. It would require rotating grabbers, though.

[AllTimeIsRelative]

How does it know how to sort the blocks by colour?

[iknowmy3table]

THOSE ROBOTS TOOK MAH JAHB

[SeanyPMac]

incredible!

[Bcdatuck]

Awesome!

[TheMackanator]

Genius 

[1995luckyman]

no live ???

[nzbmx666]

wats the point?



[virtusapiensrex]

@nzbmx666 I have to 2nd that. I can train monkeys to do the same thing.

[raghvendra87]

Can you please write a tutorial with photos to create such a system by high school students please ? I have Lego NXT but would like some advice !

[Codroid]

SCREEEEEERRREEEEEEAAAAARRREEEC­H

[joe1977poland]

someone has way too much time on their hands. other than just "fun", obviously it would came up way much more expensive than other solution.

great job on design, though

[tenshimoto]

Wow.  Nothing but wow.

[gonepishing]

very impressive work!

Any ballpark estimates as to how many bricks went into building this?

Have you used any adhesives to make things more permanent?

I especially love the control system, ingenious solution!

[theonlyshep]

@gonepishing Your guess is as good as mine with the brick count. it's in the low tens of thousands. And as far as glue, absolutely not. it's standard Lego bricks using techniques to hold it all together.

[virtusapiensrex]

@theonlyshep truly well done. You may want to try to get it approved as a video response by TEDtalksdirector to this video;

watch?v=6GEMkvT0DEk 'Marcin Jakubowski: Open-sourced blueprints for civilization'

respectively public domain a manual : ) ?

[mrmasterdocterchef]

what happens to the blocks they miss?

[theonlyshep]

@mrmasterdocterchef They just fall off the end of the conveyor. It actually will catch almost all of them, but in this video I had to set up bunch of lights because it's so dark in my basement and that affected the light sensors.

[cwbh10]

That is one of the coolest things I have ever seen!!! Congratulations mate!!! =D

P.S. did you record yourself building this at all? It would be quite neat to see.

[theonlyshep]

@cwbh10, I took just a few photos, but not much video. I wish I had taken some video, but it's difficult. I worked on this project for about 5 months.

[TestMyVidsOut]

How does the robot know where the block is as it's moving down the belt? Epic creation as well!

[theonlyshep]

@TestMyVidsOut The conveyor belt moves at exactly 100 inches per minute. At the instant the blocks pass by the light sensor @2:08 a timer is started. Since the distance between the light sensor and the robot is known (in inches) the time that it takes to get to where the robot is easy to calculate.

[jaydavey9]

@theonlyshep Do you have control over the speed of the conveyor or is it open loop? How do you know it is exactly 100 inches per minute? i.e. do you use encoders to control and measure the speed?

[theonlyshep]

@jaydavey9 I use a Proportional controller. That's a piece of code that slows the conveyor if it's going to fast and speed it if it starts going to fast.

[jaydavey9]

@theonlyshep Ok. P controller.  Very well done mate! Keep up the great work.

[preedalist]

Awesome!!!



[preedalist]

Awesome!!!



[theonlyshep]

@preedalist Thanks!

[MrEmirox]

wooooowww...!!!!!

[NeXTSTORMING]

Brilliant!!!

[theonlyshep]

@NeXTSTORMING Thx!

[LegoGuitarDude]

OMG!!!!!!!
