KINEMATICS | Serial robot vs. Parallel robot (This is not CGI)
HTML-код
- Опубликовано: 29 сен 2024
- Six degrees of freedom (6DOF) achieved in two completely different ways. The serial architecture of the world's smallest industrial robot from Mecademic (www.mecademic.com) has a large workspace and compact design while the parallel architecture of the Hexapod (also known as a Gough-Stewart platform) can reach extremely high speed and acceleration since all the heavy parts (motors, guides, gearboxes) can be mounted on the fixed base.

And this is what we need most right now! 🇺🇦😎
I mean it can do different things, like pretty much every tool
why does it feel like theres a rap battle going on
I have the same feeling 🙂
More like dance battle

That might be the most intresting video i have seen on youtube the last 1-2 years :)
Jesper, thank you so much, that's very inspiring!
the only thing that really gives away, that this is more likely real than cgi,
are surface texture, seam lines on the plastic molded parts and the finger smudges
That was extremely satisfying
Thank you!
This is mindblowing!
Thanks 😀
why would anyone think that is CG? These kind of robots have been around for well over 30 years at this point.
People think rocket launches are CGI. People are extremely dumb.
Great work - the robots, the video and the idea - thank you!
Serial robot > parallel robot.
Also I can't believe this isn't CGI 👍🏾
It'd be cool to see both doing the same routine at the same time.
Maybe someday...
Such videos remind me of having to study for mechanics 2 and theory of machnes and mechanisms. The second one i took with a heavy hangover but during the party we did a lot of talks and arguments about inverse kinematics and robots. Half liter of tulamore dew and a lot of pizza and 5 hours of sleep later...
keeping those algorithms happy...

OK. Hello, totally new to this channel. Probably answered already... What are the pneumatic/hydraulic actuators and where can I get them?!?
Oh I see. They're screw driven. Very nice. I love how smooth everything is.
"In robotics there are basically two kind of kinematics: serial and parallel. Serial robots consist of a sequence of arms whereas parallel robots take effect on the moving tool carrier directly with several prismatic joints. The resulting low moving masses enable both high dynamics and very precise mechanics."
-autonox24.com › parallel_robot
What's the point of the left robot? Seems like a more specific use case thing. In the stuff I know standard robotics to be used for the second robot is really the only thing that's useful, and the ability to reach is something that is important for pretty much every automation task
Parallel robots typically have a much smaller workspace compared to serial robots. Nevertheless, the lightweight design of the moving parts allows them to achieve extremely high speeds and accelerations (it's not shown in the video).
I'm trying to figure out whether its really big or really small machines
Great but how are they are cleaning dishes?
Why wouldn't you move them at the same time through the same translation? Seems like a missed opportunity.
I just really wonder how the left one works. Like how do they just slide on the poles?
theyre screws, look up linear screws. very common on 3d printers.
Hmmm. So it's not a lightsaber fight?
Which will win the lightsaber fight?
You choose!
Geometric algebra in action
these aint got nothin on a rooster
arent these two robot types incredibly disparate in cost and purpose? has anyone stuck the arm on the kinematics serial robot and made an even more axis movement arm.
Mount maces on them and see which one can smash the other to bits first and I might subscribe.
WHO WON?!?!? WHO'S NEXT!?!?!? YOU DECIDE!!!!!
Here i am thinking there is only x,y, and z axis
i think the arm is winning the battle
"oh yeah. Rotate that X-axis for me, baby."
"While you're at it, add in a sine-wave oscillation along the Z-axis"
Oh yeah, shake that y axis for me baby!
lol
"What is my purpose?"
"You rotate around an axis."
"Oh my god.."
Now pass the butter.
All axes*
@@brushfuse im slightly concerned about why you need butter in this specific context.
@@Sharpless2 I'm sure you've 'eard about that kid's show. Now pass the butter.

Unbelievable how incredibly still the rotation axes are!

"This is not CGI" LOL
I'm CG artist and thought at first that this was cg, and at second "damnit this guy make good renderings and engineering at the same time"))))
I'm still not convinced. The perfect shading on the backdrop and completely flat tone of the reflections and color hues makes me believe otherwise.
@@Keys879 Look at how the robots move, you can completely see that it was animated
@@Keys879 How about the shadow of the cables? When the right arm moves, the shadow of the cables of the left arm seems to react very realistically, would it be possible for CGI?
@@brockoala2994 I'm not sure what you're referencing as not much shading changes on the left-most arm's wiring. However when i even cranked up the quality to 4k/2160p it really looks fake. Even some of the material shader goes a bit haywire lol.
@@Keys879 He is PhD and he has his own site and he is into product photography too. He is just too good at what he does so seems fake but actually, he seems legit.
I am honestly surprised that its not a CGI. How stable the robots are. Theres not even a slight shaking.
Have you ever seen a shakey machine in real life? something more sturdy than a 300 dollar 3D printer? I haven't.
You can see in the close ups that the tips of the axes are shaking a bit. Depending on application this may be a non issue. If you're doing pick and place operations, it's great. But if you're doing machining, then it's pretty bad. That's why very accurate robots cost a lot of money.
it also looks quite cgi like, soft shadows and all
I'm not saying that this isn't impressive, but have you ever seen a full size multi ton industrial robot at work? Some models achieve repeatability of a few hundreds of a millimeter.
The end of the day, engineering is tradeoffs. For these bots to move as rapidly as they do for the price point they are at, they had to sacrifice some accuracy. There are ways to mitigate this.
I’m not really sure what I am watching
*trap beat starts playing*

WHO WON?!?
WHO IS NEXT???!
YOU DECIDE!!!!!!!!
This is a robot dance battle. I feel like serial bot won. Those were some sick moves. Plus, I don't think parallel but can do more than one full rotation.
But as in th description, the problem of serial is that motors are on the arm: so heavy, so slow.
Parallel ones allow all the heavy elements to be motionless, thus way way faster actions.
@@ThomasKundera you can place all motors at the base and control via joint gears and/or pulleys. your fingers are built like this.
@@krshna77 : You can, but in robotic this is not very used as it's not very rigid.
Most serial robots also cant do more than a full rotation. This is because of wiring sent though the arm. Most even have a 30 degree or so dead zone on Axis 1.
The only axis that could have unlimited rotation is the wrist axis (6 on a 6-axis) however you put tooling on the end of robots that need pneumatic or electrical control. So in practice all axes on a serial robot are maximum 0-360 degrees.
@@Komrade_juice There is a well known solution to the continuous wire limitation. A bit more complex, but reliable and well tested in brushed motors, and in 3.5mm jacks...
"This is not CGI" Made me click the video
Same
Me too. Does this constitute clickbait? I think maybe it does, because there was nothing unbelievable about it.
I added this a few days ago because I'm tired of answering everyone that it is not CGI.
@@OleksandrStepanenko I tip my hat to you good sir! Very well played.
While the parallel 6-DOF is impressive from a mechanical view, I have a slight feeling that it's range of motion is rather short compared to the other one.
But I was really surprised how it did the Z rotation, I thought it would just have a spin motor in the top.
In some places parallel is simpler and easier, also you can make it speedy. Pick and place robots are often parallel.
parallel has big torque.
The workspace of the parallel robot is definitely smaller than the same size serial architecture. Parallel, however, has a number of advantages, such as extremely high speed and acceleration, high rigidity, better accuracy (depends on the architecture).
That would make it 7-DOF
@@OleksandrStepanenko Interesting, is seems like parallel robots would have fewer kinematic singularities and more optimal power consumption due to the use of prismatic joints but the Jacobian must be more difficult to formulate. Seems like you would end up with a differential solution?
I think this is the first time I've seen a stewart platform type machine with the axes paired up like that - for a moment, I thought it was simply a doubly-braced delta machine until the pairs moved in opposite directions for the rotation. Absolutely brilliant!
me before actually reading the title:
"Wow this is pretty good CGI"
... it isn't?
@@cccbbbccc5910 check his instagram
Google definitely spying on me. Seeing this the same day I remote interview for a software engineer at a robotics firm I see this after not looking at anything robotics related online before this week. Hmmmmm.
Without even a shadow of a doubt.
Google probably knows almost as much about you as you do.
I used to think I was crazy for thinking like this. Friends used to tell me that too. But now it's pretty commonly accepted. Like yesterday, talked to my father about a friend starting a business. Didn't google any of it. Then that night I get ads for legalzoom and others. Doot doot doot
As robotic researcher myself,
I would say the accuracy of your serial manipulator movement extremely impressive 👍🏻👍🏻

I’m waiting for new gen of parallel robots that bend instead of using moving parts and 3d printable.
we have no time to await for it, enjoy engineering
The international docking standard soft capture system uses 6 linear actuators in a parallel arrangement to move a ring that helps guide a spacecraft into the docking port if not perfectly aligned.
Awesome info.

@@lukedavis6711 "yes, Ted, that was the joke" :-P
(actually, im just glad someone else got it xD)
The fact that people would think that this is CGI says a lot about how advanced CGI technology has become. If this was CGI it would be even more impressive than the robot tech displayed here.
To be fair the room this is filmed in is also lit in a weird way that reminds of CGI using simple lighting. It's not really CGI being advanced as it is the way it's recorded making it seem "low quality" in a way
It's rare to see the Z axis represented vertically
Even though it's less popular, I prefer this way.
Unreal Engine and Zbrush use Z as the up axis. I'm sure there are more, but those are massively used software.
@@8thlvlMage
Oh I didn't know about ZBrush!
That makes it easier to import/export to Blender / Unreal
Got it in my recommendation, am not disappointed
Thanks a lot! 😊
I saw more accuracy from the 6 axis Series robot. The rotation of the Parallel Robot wasn't as precise. Still super cool!
Weird how the algorithm just chooses a video like this out of the blue, I've seen the robot on the right plenty of times it seems to be a pretty commonly used assembly robot. The robot on the left is intriguing because it can do the same task but appears in my eyes to be much more modularly adjustable and variable. I say the left robot is better then the right one.
I would disagree in cases where you need to reach in/over/through something. Like putting a steering wheel on a car the left one might have issues. But where you can use it I would agree it seems much better.
I love how he had to put "This is not CGI" in the title.
Bro, the demonstration is very cool on its own, but the music is fire
It’s got the BWAAHHHHH and everything
Thanks!!!
this is mighty impressive, but something about the vibe of this video makes it feel like robot porn
So impressive! It was very important to me to show both formats running directly next to each other. It wouldn't have made as much sense if you had shown them on sequentially one after the other. I wouldn't be able to hold them both in working memory. Great job!
Thanks for the kind words, I'm so glad it's still useful!
Amazing! Would've loved some more info: which one is superior in terms of price-performance? Are they interchangeable or used for different tasks?
Thx
As an engineer who is much more comfortable in the machine shop than writing code (hint: I don't actually code, unless shell scripts count, LOL) it is the software driving these beautiful little machines - keeping track of the geometric center of the model and doing the complex geometry to calculate the necessary motions... mad respect just cuz I can't do it!
Rule34: „and I took that personally!“
Kinematics has visible z axis runout.
Quite a lot too

The robot's perfect motion, the elegance (yet simplicity, i.e. no stray wires etc.), the cleanness of the scene, the lighting and music really gave me the impression of a CGI render.

- Which camera model are you using?
- Is your soundtrack available for personal (non-public) use?

Yes, it's mine :) It shouldn't be too complicated, especially if it's a prototype. For a motion simulator, it should be a little different, but still not too complicated.
