Building a LEGO Robot Arm, to Help Me Build LEGO 

Thanks for watching, make sure you check out my NEW MERCH STORE!! brick-science.creator-spring.com

I think if the base is heavier i think it can maybe hold another camera for panning shots haha!! That aside, the editing and story is phenomenal! Even for someone like me who don't really build technic it was an enjoyable ride from start to finish

I cried, that's how good this was!

Nicely done man!

I love your videos, well done

Even though he's controlling it, why do I feel like the robot has a separate personality?

Can’t wait for a part two! Great work. Try worm gears, they give great torque, slow the motors down, and it’s basically impossible to make them slip Also for the turntable you could add a ring on top of the wheels like a mechanical sandwich to make it less wobbly

Great project! This reminds me of a school project I once had where a friend an i programmed a robot to build a lego house ;D I think we had around 5k code lines for just a 10x10 cm house with 4 walls, a door, and a window with a prebuild roof that the robot had to place on top. So seeing you struggle with just the first brick placement really brings memories back. Looking forward to seeing the updated version ;D

One day this man is gonna walk into his studio and not going to need to do anything because he’s built a fully automated lego assembly line.

Yes, this definitely need a part 2

Wow, thats amazing! I think now, you should make a brick storage unit, and have a brick selector screen. you pick a brick, and the machine gives you the box! (can be integrated onto your stash in the back)

Try using wheels for the bottom of the robot. Also part two

"Building lego to build lego"

This guy is like Tony Stark with Legos! I'd love to see a working Lego claw machine game, maybe the prizes could be polybags and Minifigure packs

This is really good! Part 2 please.

That click clicking editing is dope, Btw I think some multiple mini hydraulic hammer pushing down the bricks might be cool 😉

I like how the stream starts at 4am for me here down under.

You need weights (the battery box for example) which you place on the opposite side of the moving arm to compensate the wheight.

This would talk me like 10 weeks but you are so smart and builds this big arm in only 15 hours ,impressive

I'd love to see another round at this. Pretty awesome build and entertaining video. 👍 Maybe have the base wheels with rubber on them (I think someone else mentioned) and connect them underneath the large circle so it adds stability when the weight of the arm is extended or if it lifts something heavy. Also cool wrap built around it but this adds to weight and slows motion down too. Maybe strip it down get it working as best you can and add minimal panels to make it less heavy for the motors. I have seen some claw designs where there's a corkscrew in the middle that could help push out what is being held as the claw opens so maybe that can help it build too. Just brain-storming for you. Blown away by what you presented though. Keep at it and I'm sure you'll get it! 😊

Looks super cool, you should make a robot that can bring you whatever you tell/program it to say!

how is this guy not at 1m subs yet? he has the coolest builds on RU-vid

Not sure if you thought of it. Or would consider it, but Rollercoasters have wheels and supports on more than one side of track. Perhaps turn the base swivel into a cage bearing. Make a frame and attach another ring track on top. Might make it stronger and smoother than just making it wider. Very top heavy as well. Add weight to bottom. Alot, if you want it to press bricks together

So it can hold an Iron man mask, but what I really want to know is if it can use a fire extinguisher.

I’m surprised this wasn’t done with any LEGO Mindstorms platform! But then, I have an overwhelming bias toward potentially fully autonomous robots, which probably wouldn’t be useful in this case. I’d love to see a part 2, if one hasn’t been posted already!

🔥🦾 Amazing technical feat! all you need is an appropriate controller, or even better make an ia that can follow instructions! may i suggest, for the rotation of the base, to check out the bag n° 6 of lego 42082 set? (a red crane). Maybe it could inspire you to come up to a more solid design to prevent the crazy wobbling

It would be really cool if you could program it to build little Lego houses

my suggestion would be to add some sort of pusher as well as the pincers, so that you can grab the piece and push it down instead of having the pincers slide off

This looks SICK! You are so underrated.

Although the functionality of the robot isn't much, the arm is quite impressive nonetheless.

need to use the bananna gears to make the base rotate solidly. Also, you've got that curved wall with the drawers, have it bring the drawers out. you could use a mindstorms colour sensor at the end of the arm, and little stickers on all the drawers so its knows which one is which.

3 years from now: *”I built a full scale LEGO factory out of LEGO!”*

Looks awesome, you've got great programming skills!

Honestly the amount of effort you put in your creations and videos is absolutely brilliant, [which is why I am subscribed lol]

Definitely needs a part two.

You can do two ring gears so it is more stable

+1 to keep going.

your awesome builds are really inspiring, GREAT JOB!

I believe one of the tutorials I watched for power functions said that there is a way to set an absolute position for the motors. So you could give yourself a button that positions the arm directly over the same point do that it's easier to stack the bricks

You’d said you weren’t good at mechanical engineering in the beginning, but you are actually very good!

this man spends so much time for our entertainment, thank you

Part 2 we need part 2

If you wanted to use it to construct stuff you could put it on rails and make it work like a claw machine/3d printer

I think you should add some weight to the back as a counter weight so it’s more bottom heavy

this truly is such a great feat of lego tech, amazing work. cant wait till you make a version that's foldable or create a 100 square foot factory with it (and then upload it in a week like SERIOUSLY YOU PUMP OUT GREAT CONTENT REAL FAST IT'S UNBELIEVABLE)

My hands are shaky too I need this

Damn good robot 🤖, btw if you add wheels at the bottom it would be more efficient

Please, we need a part 2 !! This was amazing!

I was wondering what took u so long to make a video but I'm not even mad it was worth the wait I wish I could do this

Is it me or is this man progressively getting closer to being iron man

To make the main arm not as wobbly is to make rotational part wider. It should fix it.

Bro Doesn't Every Lego Fan Wanna Build Something like this

I think it'd be cool to see how you improve this thing. I'm definitely looking forward to a part 2.

You're just an awesome person! The moc is epic that I really want to make one for myself!! Also the video is very entertaining and you did a really great job!! To be honest I just can't refuse to click the like button!! #sss

you know how many extra hours of sleep i'd get just TRYING to plan that?

I really love your videos, thank you, and my 7-year-old daughter and I enjoy watching them. Do you have any tips or videos on simple basic interfaces to run lego motors? I was a Lego technic enthusiast as a child, and now I've started buying modern Lego technic for my daughter (and yes, for me too :) but the modern sets only seem to let us run the motors from an annoying app, which a) is annoying, requiring us to use my phone and touch screen as our only option to control them, and b) it even point-blank REFUSES to run the motors at all if it thinks they are connected differently to the battery box from how the set that we bought stipulated. This is totally ridiculous, because the whole point of Lego has always been (as you illustrate so well in this video here) to use the parts to invent your own stuff. My daughter and I recently built a (very simple) Lego ski lift for Lego people, super-primitive, just winding in a piece of string with a motor, basically, and I literally had to physically build it differently, with an axel fitted into a free-wheeling piece of another motor, in order to satisfy the Lego app and "trick" it into letting me just run the one motor that I wanted. I tried to look up suggestions of how to just use the motors ourselves with full control, but it seemed complicated and I don't understand what to do next.

WHY DID SOMEONE DISLIKE THIS!!!!!!!!!!

You And your buildings And mechanisms are amazing 🤩🤩🤩

You're the reason why I want to be an engineer when I grow up. This is amazing!

maybe you could build 12 claws projecting radially (like a 12 jawed chuck) from 1 motor for holding parts of big builds while you work on others or mount pieces together

We need a part 2

we NEED part two

Transforming a Technic lego set into a robot arm... This is a brilliant idea

i think for the wheel that rotates everything you should put the little wheels in every direction

these have been some of the most enjoyable lego building video i have seen, thanks for the good stuff!

part 2 needed!

Pretty please do part 2! I'm really hoping to see it.

Pt2 plz loved the vid

You you are the best. people do not respect you as much as you deserve. you are a technical genius especially with Legos

Why not use the hydraulic press piece for the brick pusher and a simple powerful motor for the rotating system 🤷‍♂️

Im getting real ironman vibes with the robot arm and i think thats great

it is crazy that he came up with this by him self all i got to say is that you are truly talented

4:09 the fact He has deadshot eyes to make 1 vid for us

guess the issue is the weight in the arm, for the base to avoid beign "tilty" use bearings between 2 circular parts (those made of 4-24121) not on 4 points but at least 1 each 45 degrees (8) than as long as a gearbox could be used to multiply outputs insted of changing speed with really few efforts just use a 3 output turntable plus a sequential gearbox as a function multiplier (up to 9 functions) all the weight will be in the base.

you have made that thing for OVER 50 HOURS CONGRATS

You've inspired my son to try this out! Would love it if you made a part 2!

The fact that you could even make the motors work is godlike, i would literally give up within a minute.

“I’m terrible at mechanical engineering” *Builds the sickest robot arm I’ve ever seen*

Add some Googly Eyes Then It Would Be Cute😍🥰

Your creations should be a real Lego. They’re Awesome

I've never seen anyone build a remote controlled minifigure, that can walk around and everything! You'd probably be the first person to do so!

Brick science 2022: making a working robot arm with Legos Brick science 2032: making a working time machine with Legos

A suggestion, use gears and belts when gears wouldn’t be economically feasible… and more than one motor if power or power and speed are desired…. And a hint… think back to your lego motor… and remember that not everything needs to be capable of 360 degree rotation, most of that arm needs 180degrees or less… that arm could still reach everywhere even when limiting a given axis’ total movement… (an arm can reach above it if it’s previous axis can rotate 180 degrees) if the base (using gears and multiple motors)and the wrist can achieve 360, actuators assisting gears to increase lift speed and perhaps two motors and gears run the wrist, and gears for the claw to increase grip strength…

Damn he really passed the "im not a robot test"

This guy is so underrated

The motors and battery boxes from the set is LEGO Powered Up.

the amount of asmr he puts in these videos in awsome

If we’re ever need The Avengers Initiative in real life, I’m booting this man to be our Tony Stark

Did that’s an amazing build, I can’t imagine me buildings this in a million years

Why don’t you build a mountain railway (I have a plan for the locomotive!) Make it look like the engine Snowdon from the snowdon mountain railway, using an open gear smaller than the wheels, put a gear rack in between the rails that will mesh with the gear. Curves and points will have to be level, to keep the engine from slipping

SO CLOSE TO 100K SUBS!!

7:04 it's nodding and waving :D

I never new a robot hand could be built with nothing but Lego, I love your vids your a legend

this dude spent like 20 days on this he's like 1 of the most patient person in the world

SO AWESOME DUDE!! I didn't even know those mechanical LEGO pieces even existed until I say your videos

But now make the first robot arm make another robot arm. Then make the two arms make a body for each other. Then make the upper half of a body make two legs for itself. Then a military grade nuclear reactor to power itself and a make it code a brain to put in a head like object to act like it's head. OH and make sure it's like 10 story's high. And then give it a powerful Lasser bean that desentergrates super mutants and synths. Then find an military bunker that has enough mark 28 nukes to completely load you robot. Then call it Liberty Prime, destroy the institute, and get copyrighted by Fallout 4.... 🤗

robotics isn't hard as long as you set up a plan beforehand, since there aren't any unique parts its just like stacking blocks

I bet In the future this guys whole Lego studio will be made out of Lego

Awesome video! Now, it needs to be asked: can it hold a fire extinguisher like 'U' from Iron Man? ; )

imagine how your body is complicated when this is already very complicated
