the fact you guys made a robot that just fucks around all day makes me concerned and happy
Show this to any professional Kendama player ever and he'll know what it feels like to lose a job for a robot.
That is exactly what i was thinking
same thing in my mind
That's the coolest thing I've seen in a min
with this thing gravity seems so slow 😂
yea 😂
I keep getting cable-driver robots in MY RECOMMENDED! Did I flip a switch or something? (Don't get me wrong, I find the invention quite interesting)
me too, best guess is i searched the term Voron a couple weeks ago hearing in in 3d printing circles
I got in that loop too...
@@murraynatkie7490 searched Voron and ended up here a week later.
It's almost like the AI is trying to make us give it better manufacturing powers... 🤫
And flexible airfoils
That's amazing!
Thank you for this demonstration.
that was unexpectedly amazing
Какое нужное и главное полезное устройство!))
Beautiful!
amazing demonstration!
1:30 My friend Wumpus here has no friend to play catch with. He's a solo player.
Hope he doesn't become neurotic. So alone. Maybe that's how skynet started. xD
Самый главный вопрос, это движется ли каретка по заранее жестко запрограммированной траектории (и наличие мячика - просто декорация, каретка будет повторять свои движения хоть 1000 циклов, даже без мячика)?
Или там есть система отслеживания перемещений мячика, и необходимые координаты для позиционирования каретки рассчитываются в реальном времени?
amazing tech!!!
The music was a perfect selection
impressive! VERY!
Very cool!
Awesome!
Can you upload a version without background music? I want to hear the machine.
What you hear is the sound of that machine.
@@mareksarvas1102 What I hear is the sound of Offenbach's Can Can drowning out the sound of the machine.
Obnoxious background music is a surefire way to ruin otherwise good content.
@@tissuepaper9962 I think the choice of music is great. Don't teach when you're deaf. :)
@@mareksarvas1102 Even when the piece was written it was obnoxious, that's kind of the whole point. It's from a comedy.
I find it distracting. If you enjoy it, that's good for you, I don't judge. I would personally like to hear the sounds of the machine unadulterated.
if you reaaaally hate the music you can mute it by pressing M
Impressive !
Great song choice to go with this WOWSER of a technological feat!!!!!!
We've been blessed by the algorithm.
No frkn way Coolest thing I’ve ever seen ....I think! Lol
Very impressive.
that is amazing! Is there any related cable drive open source project?
So that's what one of those claw machines look like when they've been picked clean.
Finally a use for a cable robot
They're using them to cleanup Chernobyl under the big cover they built.
nice programming!
Witchcraft!!! But honestly well done. Breathtaking.
nice!
feels like i'm looking at a couple of pre-programmed motors
Здорово!
Excellent
Awesome
1:50 Spider in the basement after you disturb it's web.
how many motors use in this robot? 4 or 8
Could you make a theme park ride out of this? Not the ball part, but cables moving a ride vehicle around in a 3D space. There's so much potential for every ride to be different and easily customisable. Would it be safe enough to not worry about cables snapping? You'd obviously have to move it around a lot slower to avoid whiplash.
This robot software was already used for virtual reality for people sitting inside. But there is no video on RUclips. I do not hava the rights to upload it, it is customer thing.
@@andrejrajnoha3938 i can definitely see that put into that application for VR. In which way remains to be seen, something to look forward to!
Still it’s an amazing mechanism!

may i ask how is it with a precision if used as 3D printer head?
It depends on many things but small scale 3d printer for home use using cable robot will not be better than basic CNC. It is good only for a big scale 3D printers (printing buildings and so on)
Nice promo
Now we can finally perform the rasengan
THis is cool.
This just might be the only thing faster then my grades dropping.
Is this the first boss?
まじすげー。
I wonder how the codes look like
So… what can this technology be applied to?
I mean, I think 3d printing is possible with this technology, but what else?
motion simulation
Well, that's something.
cool
perfect❤❤❤❤❤❤❤❤❤🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
Definitely cool but has anyone come up with a practical application for one of these yet xD? - I'm struggling to think of one where the cables wouldn't constantly get tangled in whatever it was operating on
seen a 3d-printer driven this way once - looked cheap and not that practical^^
Big scale 3D printer is possible but only for big scale like buildings where you have a heavy TCP therefore all cables will lead from the top - cables will not collide with the object in a space anymore. But there is much more possible application where you need big scale robot and cheap, farming, painting, ...
Of course there is a practical application for this. If they done right, you start with equations that describe the physics of this system. And those are the most important part.
😍😍
I wonder how all the cables maintain proper tension at every possible position/trajectory and head orientation? Is it a combination of math, calibration and array memory? Because that would be a massive amount of data to learn if it wasn't math. I wonder if there's one or more "master cables" the other ones follow? How do they set a datum? Etc etc lol
You basically just position and orient your thrower/catcher thingy in virtual space, measure the length that the cables would be in that position and then use motors to extend/retract the real-world cables to the target length.
I'm sure it's more complex than that in reality but the math of actually figuring out how to control each cable to orient the thing is just a basic distance calculation.
@@BoJaN4464 Im pretty sure that it is also needed to calculate the line to the target location and the length of the cables at every point along that line, otherwise some cables could become slack and others too tight during the move. But still, its just some simple geometry and calculation that is very easy for a computer to do.
It is just math calculations. You know where it shoul be in the space in X,Y,Z position. Now you use math, matrixes and geometry to compute the vectors for cables and then you compute motor position for every cable. Is it quite simple. Math from secondary school.
@@andrejrajnoha3938 which sensor did you use to measure tension and keep it tensioned without any slackness?
@@fba132 only motor torque. No other sensors needed.
What motors are you using?
Cool vid
Robo bartender
Was this preprogrammed or ai real-time trajectory calculation!
Real-time trajectory is calculated and AI is not needed for this simple application.
This would be a very fun carnival ride if you just scaled it up
Except for the 10G of acceleration it's pulling! That's incredible
This vending machine took my dollar and now it refuses to give me my tennis ball
Wait brno? You mean Czechia?
wow
Ummmm, shouldn't it be: CableEndy tosser - cable-driven parallel robot (B&R Automation)?
Are you bro cant share code ?
Damn. What Ryan Faulkner said.
on commence par le trio mais vous les connaissez déjà (sinon c est insane)
First seconds look straight up cgi xD awesome
whats the background music name?

👏
Ouah 😳
why does it say "Fart" on the ball
So, if they have really strong strings - they have developed a new type of food processor. They call it.....FRUIT NINJA!!!
should be fast enough to juggle 2-3 balls. they could be droped in from the top by servos as per program. not as fast as my buddy jack who was able to juggle 5 balls AND still carry on a conversation, but impressive notheless.
Well, its not exactly perfect is it?
👁👁👍👍
Active damping on high rise
Sweeeeet
Who paid for this?
Very impressive, but it's not technically "Juggling". It is juggling only if there are more objects than there are "hands". So you need to find a way of introducing a second ball! The machine looks like it would be fast enough to do it. All the best.
Hello,
I'm a student at ECAM Brussels Engineering School, in MA2 Automation and as part of my final thesis, I'm working on a cable driven robot that can move in 2D.
I have already read a lot of articles on the internet, and I understood that the heart of the control of these robots is in fact a tension control in the cables. However, I was wondering if a control in the angle position of the motor (number of revolutions that the motor has to turn according to the desired length of the cables) was not possible? Have you explored this possibility? Would it be impossible to perform a position control and ensure sufficient tension in the cables?
Thank you in advance for your help,
Yasmine
Technically it is possible but I think it would be more complex to control angle position of motors and more possibilities of error, while adding no benefit to the system.
However don't listen to me or anybody saying "this is impossible" or "this is not how you do it, because..." This is your thesis, your opportunity to experiment and learn, so do this - study, experiment and learn, don't afraid to try something new and make your own conclusions. That's how we move forward as a species.
Good luck with your thesis :)
@@Leo3ABPgamingTV Hehe thank you for your answer! We will probably explore this possibility, hopefully we can learn something!
Best regards :)
Position control of motor angle is possible way how to easy do a cable robot and also if you do not have end TCP position sensor. Tension control is possible only if you have end TCP position sensor for feedback control the end position or to control tension in cables. This will be more precise, will avoid to loose a position and avoid instability. For the demo robots like this the motor angle position control is OK but you need to know if your end position is stable. Real applications without tension control will not be good and precise.
I am doing a similar project this year a 2 d cdpr if you are free can you give me some guidence
Pure comedy!
Pardon me, but though the inscription says that this is a six-axis, I don't see rotation of the head in this demo. Wouldn't that mean that it's really a five-axis?
In any case, it's a wonderful machine. I'm interested in using a similar method of actuation with an octahedral geometry to make an auto-pipetting robot. This far surpasses my expectations of what would be possible with such a cable-driven machine!
Thank you!
The robot algorithm can achieve 6 DOF. BUT, it actually depends how the cables are lead from the motor to the TCP. In this case in the video, my aim was to achieve good TCP stability and the best ranges in rotary axes A and B, but C was not really needed. As you can see from the top view, if I would try to rotate around Z axis (rotary axis C) the cables can pull the TCP only few degrees. And also, for the "juggling" with a ball this movement has no effect. Every construction type and rope fixing has some pros and cons.
take my money
I normally heckle robots I see here on RUclips, and they generally (in my opinion) deserve that heckling. I'm... not in much of a mood to heckle this one, though. It's shockingly fast and it's very well thought out and implemented.
OK, so there isn't much practical value in it... but this one is at least very entertaining. Because it's so fast, and its movements are so clean, and because it deals so well with acceleration. These things would be perfectly well suited to egg throwing.
There is a lof of practical application. Usually for big scale application. Building 3D printing, pick and place applications, painting, farming, virtual reality, windows or planes cleaning. You do not need to have cables leading from the bottom if you have a heavy object.
@@andrejrajnoha3938 You really sort of do, though, because the bottom cables lend stability that you don't have if you use only the upper cables.
If you used this approach for building 3D printing (which is a fool's way to build buildings, of course), then you would absolutely require at least four (insanely expensive) cranes and you'd need to guarantee that no humans could possibly enter the building site because (1) electronic equipment cannot reliably detect humans and (2) any intruders, if detected, would badly hinder the building process. So that one is unrealistic.
Painting is unrealistic because the 'bot couldn't detect whether it was doing an acceptable job. Likewise window cleaning... which would also require four overhead cranes under all-electronic control, a condition which is unacceptably unsafe. Electronic stuff fails. Stuff falls. People die.
Pick-and-place... I'll grant that, but the machine would be needlessly complex. We already have simple, reliable machines that do pick-and-place very well, and they don't require a great deal of extra energy to keep the cables taut like this machine does. If the cables aren't very, very taut, the contact head can't be held stable in a predictable position or orientation.
😲😲😲😲
выпусти ты его.
if quicksilver was a robot
why is this funny to me
egg please ~~
So what this means is... We have balls the size of houses with reinforced and protective packaging, so we can start fucking slingshot launching packages into another city. Where then the next city's slingshot CableEndy station receives/catches the package, thus launching it either back or on to the next city. Yes. LMAO
When the outlook of earth starts to look more and more like an atom everyday.
make it juggle
i'm sure darpa will find a way to put a a gun on that somehow
Hmmmmm. With just two simple linear manipulators one could for example make a fighter jets gun able to turn in a smallish cone to assist in aiming it or something.
Guns in jets are pretty obsolete tech, but still.
neat
now do it with an egg
lets see two of these play each other without feeding each other data...thats not happening is it?
OMG that is so fast

That's not juggling, it's catch. ;-)
This is the second time I've seen a robot like this and I still don't understand its purpose.

There are soooo many wet engineers in this comment sections!! xD
I am disappointed since robot cannot do diagonally
A přitom taková blbost co?
thumbs down for the loud music, rather hear the sound of the machine
Not exactly perfect as you say, but cool it is.
