It's really cool to see a machine move so organically... almost as though it's alive.
I love that type of machinery that moves very organically
Plot twist: right as he remembers he didn’t turn the divice on is jumps at him
“Organic” are you a Whole Foods employee
@@ObamaGaming3.0 just be quiet bro..
@@RuJigglo you mad for what though
Impressive how strong these joints are
Yeah, I thought it could fall, but no. It's an amazing design.
Have you ever stepped on a lego? They even hard to dent with teeth.
@@banditoincognito8950 Yeah ABS is pretty strong
😩
You should see how strong blunts are
This really needs a Dune Sandworn skin and maw. Outstanding construction!
My exact thought
exactly what I thought😃
Wouldn't it be funny if that's what the sandworm sounds like, only several pitches deeper?
The Shai halud
The same idea is used in the F-35 B tilting nozzle
I was coming to the comments to say that but I see you beat me to it
Actually he already mention it in the subtitles...
@@gustarrezende i didnt see that tbh, must've missed it
they literally said that at 6:40 reference 2
@@oiytd5wugho like I said, I must've missed it
I’m always amazed at the unique ways you create new and interesting mechanisms. I would’ve never thought to use 1x1 round tiles as bearings!
If lego doesn’t employ this creator, they are making a dramatic oversight.
This tactic has been used in other MOCS before, but it's impressive nonetheless
-It does get used in an official set! The bucket wheel excavator set uses this technique for its turntable.- -See Jarek Myszko's response.
@@lucasbrunner6283 Not true, I have this set in front of me and it uses wedge belt wheels as bearnings :)
Me neither that was brilliant
Very interesting.
I will theorise here that because the joints are at 25 degrees angle, instead of 22.5 (Which would be half of 45, or 1/8th of a 360 circle), this is why some movements or positions look like they're not quite straight. But obviously you're limited in what angle you can make by the lego parts themselves.
You would be surprised
As this mechanism is used as a thrust vectoring nozzle for a VTOL jet, I guess the 25° ( --> "overbending") are intentional. This gives the aircraft somecontrol authority in every direction when hovering.
These crazy contraptions never cease to amaze me. I can't wait to see this as a great ball contraption.
It would be awesome if it could pick up the balls and then 'eat' them so they fall through the middle and out the bottom like some sort of worm creature.
YES
It would also be useful in factories as a way of picking up items and immediately transferring them
@@BurgerSoda lol you should patent that idea...(Industrial robots for pick/place manipulation have been using joints and motion like that for years)
@@ccllvni can’t believe this man created an amazing original mechanism out of lego that hasn’t even been invented yet and he doesn’t even know
Make it 10 times longer with a claw in the end and 4 units in total, mount them on your back with a custom lego strap around waist.
You got then an awesome Doctor Octavius cosplay :D
good lord.. just when we think you have reach a pinnacle in design something new and amazing comes out... This is beyond cool! I like your use of pips.. will have to remember that one
Ive known and treasured Legos all my life.
Yet I keep being suprised at how rediculously well designed every single Lego piece is and thus allows stuff like this here.
Best "Toy" in the history of humanity.
I love how it gives off TF3:DOTM driller vibes and how it moves so organically you are truly ahead of your time when you build such amazing creations you've made
I see what your saying but my first thought was that it looks like the devastators neck from TF2.
I don't think you know what "ahead of your time" means. This principal has been used for decades at least.
over 10 years on youtube and that is genuinely the coollest/cleverest lego robot I've ever seen, truely remarkable work of design
4:50 is like the Pixar lamp animation
Basically what I’m saying is the next step for this is making it jump as a whole apparatus
I can imagine several ways to incorporate this into a GBC Module, but mostly I'm excited to see the amazing way you will do so that I can't even conceive. Amazing work!
I never thought of using this structure again. It's amazing.
Amazing job, both building wise and filming wise. You showcased this build in such an excellent way, and all shots were lined up to the build. Just beautiful!
Love this! In a lot of industry's you can see robot arms function in a similar way. i.e. transporting things parallel to the ground/the walls, to not bend or deform etc
I tried to design one of these a few months ago. Happy to see a version that works!
This shows an INCREDIBLE understanding of engineering, physics and of course LEGO. What an amazing display. Well done!
This is the best lego project i have seen in a long time. the movement looks so natural. Thank you for sharing this.
Will the cables get all twisted up if you keep rotating the same way or is there a way to prevent that?
I think he marked the joints with triangle stickers(?) for it.
I think it would be possible to splice a slip ring into the ev3 cables which would allow unlimited rotation.
@@wanderer3757 I think the arrows are used for calibration.
Eventually I think. Use a long cables to have enough play in them.
@@Jorazon1 Slip rings can really suck, but for something like this they're okay. A mercury slip ring would be great, but those get pricey.
I love that it is effectively hollow. You could run a tube through that.
Definitely one of the most impressive lego creations I've seen
Interesting structure. It would have been interesting to have all the motors in the base and use universal joints or CVT joints to run all the parts. That would allow unlimited movements without thinking about wire twisting.
That’s amazing! Everything down to the round tiles as rollers. Incredible! Great work!
A fun thought: add one more module, make it a bit sturdier, carefully account for balance and have batteries, and you’ve got yourself an interesting Slinkybot that, when enclosed with a flexible shell, may work better as a Mars explorer because it can’t get wheels buried in the sand. It may help to change the number of degrees for each segment, and not being constrained to Legos, that’d be easy enough.
That movement was so satisfying to watch! That was amazing
I never knew these Lego stepper motors are so accurate! Very cool project.
its like a air duct joint, but motorized. very neat!
Brilliant work! It's such a fascinating design. A way of "bending" a joint without having a hinge which gives robots an incredibly wide degree of motion.
There are analoguous structures which have evolved in the legs of insects: joints which only contain rotational segments, but appear to bend much like our elbows.
It would be pretty odd looking if humans had joints similar to this. Could you imagine how bizarre something as commonplace as _Walking_ would look..!?
This is exactly how the cameras in an endoscope work… this type of motion helps us in visualizing the surrounding better.
This is mezmerizing. Thanks for explaining how this is used in jets.
The second one seems like a great armature for deep-sea diving suits!
What a great build. I could imagine someone using it as part of a GBC 😃
That is hella trippy to watch in motion. Super awesome Lego Technic robot.
I love the design! The way it all fits so flushly together gives me dopamine.
I imagine that wire twisting would eventually become an issue, but it's still very cool.
Yes.... i wonder if the arm were to keep on rotating, how would the cable manage the twisting motion.
@@chnanhaurliew6519 slip rings at the joints can be used to prevent this issue
It really is amazing what can be done with Lego nowadays!
incredible how it's in concept quite simple, just rotating wedges and yet it's movement can be so complex
These things are hypnotic to watch, I love them so much!
You could totally use this as a GBC machine. Balls can travel internally once you enclose it properly.
Such a cool design! The movement is mesmerizing! Would you consider putting in the time to build a sturdy enough 6DOF version or has that endeavor been fruitless already?
This is absolutely insane. Thanks for sharing. 👍
Long live Akiyuki!
We're blessed to witness your genius!
I have indeed seen fighter jets with this mechanism to achieve VTOL. But I have a slight hunch that we can expect a new GBC module with this…
GBC yes! Or some menacing LEGO death worm ^^
@@HoshikawaHikari I'd expect the latter one!
@@HoshikawaHikari The great Shai-Hulud...
inb4 akiyuki gets hired to build fully lego VTOL fighter jets for the military
Only the f35 uses this mechanism
This is how the f-35 tilts its engine btw
This is incredible work, you never cease to amaze me Akiyuki
Man, you just blew my mind. I need to build one of these to play with now!
study engineering? no thanks, I prefer legos.
Nice profile pic
I agree
“Lego”
動きが可愛い！
垂直離着陸機のバーナーの部分がこうなってたとは驚きです
F-35のノズルがまさにこんな感じだったね
@@user-denshikousaku_staygold 日本も購入してる奴でしたっけ？自衛隊の公開演習みたいなので見れたりするんだろうか、、、

That is so awesome again! Never thought I could be a fan of a MOC builder, but actually I am! Hats off again Akiyuki san
This is amazing and I can't wait to see this with an end effector on it.
can you give it eyes, preferably googly eyes
Everything's better with googly eyes!
pov your in area 51 deveoping the f 35
Lego has taught me so many things and it is continuing to do so even now, when I am not actually using it. Also thanks for this video, it's great
Brilliant! Mesmerizing! I could watch this all day!
amazing representation of the possibilities
this is great to be applied on flexible big pipes and a bunch of cables
You just made the perfect motion control camera mount! Imagine what you could do with that!
WOW. ABSOLUT MASTERPIECE. Amazing work.
Okay this video and your creation deserves millions of viewers and likes! Absolutely an amazing piece of work!
This is a great contraption!!!
Congrats!
You have to be the most amazing and creative lego builder on the planet, it is beyond me how youtube has not send you at least a letter telling you how awesome you are yet
Insanely cool
Truly remarkable
Absolutely brilliant!
That is straight up incredible!
Wow! what a great mechanism. The posibilities here are pretty staggering. You are an impressive mechatronics engineer, a new sub
This is insanely awesome
Really impressed. It can move in ways that are really efficient. I learned something today!
This is the channel that just keeps in giving
i wish to see this done with even more segments and see the more intrestring and chaotic'y mesmerizeing ways this device can move
this is the best lego robotic worm i've ever seen
man this looks amazing
Thank u 4 sharing
You, sir, are a genius, your a brilliant engineer
This is very cool, I’m amazed you got all the little 1x1 circles for bearings that is really smart. Also this thing looks tripy and wack 10/10 build, nice one man
Cool design, but when it started moving, damn it was unsettling yet satisfying to watch
stunning!
Bravo, extraordinaire, merci!
Awesome!!
Thanks
Amazing!! Please continue with this idea
I like the arm mechanism well thought out. I like how the video was made. I like being able to see it so clearly and completely and then from a new angle and again clearly and completely
A Plus thank you excellent
Outstanding!
Nice design, there is so much room in the middle, this would be great for docking planes
There’s a beauty in how swiftly an otherwise fixed machine can move
Perfect.
That's freaking amazing !
this looks like it straight out of portal, daaammnn
Wow! This is amazing!
Wow, that is cool Lego technic project. 👌👏
Beautiful
I just found this on my recommendations and I have to say, this is amazing!
dude, this is awesome
Brilliant design.
And we're one step closer to getting a life size Lego Doctor Octopus. Great work!
this is really inspiring to draw some mechas concept art
Incredible as usual!
What an elegant robot arm!
the fist one is perfect for the usage as a turret ring in very hefty tanks
