KINEMATICS | Hexapod (Gough-Stewart platform) 6-axis parallel robot (This is not CGI)
Vložit
- čas přidán 5. 07. 2019
- Being invented in the 1950s, the legendary Hexapod continues to admire us with its elegant movements. Its simple architecture inspired generations of engineers, scientists and hobbyists around the world to replicate and study it over and over. The Hexapod (also known as a Gough-Stewart platform) has six degrees of freedom (6DOF): three translational along x, y, z and three rotational about x, y, z. The kinematic structure of the Hexapod is based on a spatial truss which makes it incredibly rigid (comparing to the serial robots) and capable of manipulating the high loads. All this combined with a very compact design enables it to be successfully used in multi-axis positioning systems such as flight simulators, telescope positioners, oscillation simulators, micropositioners for optics and so on. It would be fair, however, to mention that the Hexapod architecture has very limited tilt angles (usually ±15-30 degrees). Moreover, increasing the tilt angles causes a significant decrease in the workspace of the robot. Nevertheless, this does not diminish the value of this type of robot, but only determines the area of its use.

I just had an idea for a really crazy toilet.
DUDE! you mean 3D printing with poop?
@@cobralyoner With RGB LEDs.. YES! Let it be PinUpPooP!
This might be one of my all time favorite youtube comments
The stabilizer toilet......
Japan could do it🤣🤣
I ...uh am listening
lighting is so good i thought this was cgi at first but the sound convinced me it was real
they also did a video on how they filmed everything, it's pretty cool.
Thank you! 😊
@@OleksandrStepanenko for better quality you should mix sound w music properly, otherwise some nasty dissonance appears.
Finally a robot stool that anticipates where my ass will sit.
That is beautiful .
It sounds like an iron Man suit I love this I've been watching this for the best half an hour
Минимализм, эстетика, кайф ,хороший вкус, шедеврально, моё почтение.
Большое спасибо! Очень приятно!
Great clean design
Thank you!
Silky smooth!
Thanks!
Such and impressive piece of engineering, I wonder if it could have some use in solar arrays to allow any panel angle.
Thank you!
Sure, the parallel mechanisms can be used for that.
It would but I don't think it would be quite the way to do it because that would be more expensive than some regular two axles rotators
Definitely a little bit overkill lmao.
This is beautiful
Thank you!
beautiful design, execution, and cinematic capture!
Thank you very much!
This gave off a portal vibe to me lol
Дельта робот наоборот. Относительно простая вещь для тех, кто хорошо освоил школьный курс математики.
Автору респект!
Y'all can build a badass robot with that
This was so good I feel like I watch something naughty
Looks cool. Why are the joints smaller on bottom than on top? Are those setscrews holding the bottom joints in place? Also where can we find that cable strain relief?
Hi, i love your model and i made it in cgi :)
Awesome! 😀
where can i find the background music. much techno :-D
I like the noises
This would be great to use as a camera tripod on a boat
Praise the Omnissiah!
Cool 😎
👍🏻👍🏻👍🏻
Neat chair lol
hypnotic.
What kind of software do you use to program all these different configurations?! Surely you're not writing each stepper individually
Mach3
If a bald man with sunglasses wants you to order one of this to mount a 120mm automatic gun, DONT TAKE THE JOB. You are welcome.
😄Thanks
That. Is. Cool.
NIce! so do you metal 3d print your components?
Would be great for motion simulators for video games, or flight simulators
They actually use this arrangement for flight simulators
your videos are amazing. they seriously look like 3D CGIs. could you please show us your studio setup maybe in future videos?
Thanks a lot!

What's the load-capacity of this robot? In a different video of yours the "arms" seemed rather small... so I'm assuming not all that much? Anyhow looks really great!
its like an upside down delta 3d printer and those usually dont like heavy heads like direct drive so i dont think much load capacity.
@@randomstuff-cu4of Upside down delta isn't exactly correct. With six actuators the load can actually be quite high, and depending on the mechanism used a DIY linear actuator can easily push more than 1000N force per actuator.
I mean it'd depend on the actuation method you used. If you used 6 individually controllable hydraulics you'd have something that could crush a person with 97% extra capacity to spare. While the "legs" are all at angles, they're pretty shallow angles all things considered, so you could *_ROUGHLY_* think about it like just having 6 hydraulics put next to eachother. You could also just use weak as fuck solenoids or something and then it's load capacity would be zero, it all depends what it's made of.
looks like something out of portal
Time to make a core in real life
they did actually model these on a lot of the robots in portal 2
@@commodore7331 yep
Hi, sorry to bother you. May i ask if you use some transducer and which (typology, i don't really care the brand).
I'm doing a research for school but i can't find anything about transducer.
Good job btw
Hi, no I don't use any transducers.
Like muscle fibers
Is that Acrome Robotics Stewart Pro? Looks just like it
No, that's Oleksandr Stepanenko's Hexapod.
0:18 These sounds...
Beautiful. I love the short well filmed clips. Would be perfect on tiktok. Do you have a tiktok account?
I like it.
A LOT!
Thank you!
very realistic cgi

@@OleksandrStepanenko i know i was just joking around ! D:
🌪️
I was really hoping they would do wobble pattern like a rolling disc would do falling on its flat.
Check out my other robot, is this what you wanted to see? czcams.com/video/gKlqojXk1nw/video.html
Nice work! The design is so cool 😎👍👍. Can I buy a couple of such robots? Interested in shipping to Europ and US.
Will threaded rods from building material shops like Canadian Tyre or Homedepo work ? Thanks
it depends on your application, if you are willing to only mimic the moves in this video it's doable, but if you are looking for precision need at least lead screws (like 3D printers), then ball screws...
@@zanak Thanks!
New gaming chair idea?
Well, not new:)
This makes me want to combine this with a rocket engine.
nice stool
portal 2 was accurate
what software did you use for this simulation
This is a video: instagram.com/olekstepanenko/
@@OleksandrStepanenko awesome. How did you find yourself there ?
@@astasna Thanks, Dominique! Difficult to explain in a few words, just love robotics 🙂
would you please share a link to the code that runs this platform ?
Are those moving on actuators?
main issue i see is range of motion... any idea on how to make it bigger ?
It's not an issue depending on the use. Something like that is used on the space modules docking rings.
Почему моё воображение дорисовывает сверху на этой штуке... железный череп с красными глазами?
Jumanji
Sir can u tell me how it's working pls sie
Please find some information here:
en.wikipedia.org/wiki/Stewart_platform
Let me know if you have any specific questions.
What 5 axis? This can modulate the effector.
x, y, z and rotation Rx, Ry, Rz
When you have a few too many tabs of lsd and you go take a piss
dude...
What kind of dark magic is this
nasa had this stuff well before anyone
The angle is wrong,I designed a plate with 6 axis can sit 24 people at the same time.
Hanzhen harmonic gear , robot joint gear reducer, over 30 years experience ,
i'm wondering why paralell axis? is it for cost efficency ?
It has a number of advantages (compared to serial architectures), such as high load capacity, high speeds and acceleration, small footprint.
I love that kind motion
What motors did you use?
Most probably it might be stepper motors
Wait, this is air not hydraulic?
Добрый день. Если позволите, два вопроса:
1. Можно, пожалуйста, не так круто? А то прям за свои поделки браться не хочется, глядя на это. :)
2. Что за соединение в месте крепления актуаторов к верхней панели? Выглядит, будто платформа просто лежит на шарах.
Спасибо :) Я думаю, это должно вдохновлять делать еще лучше! Сверху я использовал магнитные сферические шарниры (стальная сфера и магнитное гнездо), хотя они слабоваты для этой компоновки. Обычно такие шарниры используют для хобби дельта роботов/3Д-принтеров. Снизу обычные карданные шарниры. Вот еще подобный вариант:
czcams.com/video/ouyx65C7L-o/video.html
Oleksandr Stepanenko спасибо за ответ. А если бы Вы укрепляли верхнее крепление, то что бы взяли? Скажем, если на этой платформе должна стоять ещё одна такая же платформа.
@@zakharsk Наверное карданный шарнир вращающийся вокруг своей оси. Хотя это зависит от компоновки. Здесь, например, другая конструкция: czcams.com/video/G_UmhUjZhNo/video.html
How do you make the animation with the accurate sound ? or is it real lol ?
What is real?.. 🤔

I think he's talking about the sound of moving parts of the machine.
Great job btw. Even watching these things that I Donnu what it is , is satisfying :)
SaNaHeyrati Thank you! Then I’m happy 🙂
It's not CGI, but the scene he makes to film these needs some imperfections so you can tell that it's actually real.
Is this only a design or you really built it
Yes, the robot is real, I'll post some photos later.
Looks like it could be a helicopter swashplate
yo u need to talk to darpa man
Nice toilet seat adjuster you got here.
Que soft usas?

if it isn't CGI what is it?
Studio filming.
@@OleksandrStepanenko it looks so much like cgi tho
good cartoon🤣🤣🤣
sure sounds like a lot of friction going on.
This is CGI
