RUclips algorithm: Are you interested in robotics? Me: Er, I don't know anything about it, so- Algorithm: Ok lol anyway here's a dope video about a ball joint
Here are some additional details that you may want to include in your translation: The mechanism was developed by researchers at Yamagata University in Japan. It is called "ABENICS," which stands for "Active Ball Joint with ENgineering of Spherical and Saddle Gears." The mechanism has potential applications in robots, medical devices, and other machines that require precise positioning and control.
@@MasterCookies the movements normal but the idea of knowing how to manipulate several movements to get the final output movement is whats dogshit, its a fuckload of maths and not very visualizable in terms of mathematics

It's like the ball is threaded in the way a multi-directional screw would be threaded (it can engage or disengage clockwise or counter-clockwise, depending on pressure... generally impractical for screws) and then the driving ball joints are the single-direction threaded guide, but turnable so it can engage to turn the multi-directional threading on the ball. Very neat!
This video is quite dense in terms of information but it's so well explained through the animations, barely have to pause or slow down at all to understand it. Absolutely incredible design
This is so beautiful. It's so intuitive and makes so much sense but coming up with something like that is crazy! Now I'm very interested in the math behind it, are the driving rollers working on some weird core XY variant? What's the math behind roller input and output shaft position. I want to know it all :D
It probably doesn't actually know the angle each axis on the ball and calculates how much they will change depending on the speed, direction and angle of the driver gears and keeps track of that
@@kolterdyx I agree with you completely. I work for a company designing and testing precision motion control systems, and while it would be possible, and not too difficult to use motors with built in rotary encoders, the lack of encoder wires coming from the motors show these are running in open-loop with no position feedback. If you had motors with encoders and pair each set of motors on an arm in standard XY configuration(the 2 motors would be offset 90°), then you could do the trig calculations to calculation the physical travel/rotation of the ball. Then interesting part comes on how you want to handle the second set of motors on the other arm. You could either do the pain in the ass over, complicated route, of having all 4 axis running in sync to handle each command if your software will allow it(I've done it on hexapod systems, and it is a lot of math and an absolute pain), or assign roles for specific axis. I'd probably have one arm handle the XY rotation, have one of the motors on the other arm handle the Z rotation(the X and Y will need to be set to slaves axis of Z to rotate when it does, while still following their own commands). The 4th motor on the arm with the Z axis, I would have running constant low current to always be opposing a primary axis to prevent the backlash issue seen at 4:35(the jerking at the start of the movement is the driving motor is shifting the contacting fact of the ball's gear). While this is a cool concept, the backlash issue inherent to this design rules this out for any precision work, and the low contact area because of the possible tooth width means that with any load added, you'll see wear become a more serious issue. With wear, you will increase your already existing backlash issue, and at worse, break a tooth or one of the rollers on the motors. This will not reliably be able to handle loads, and if a tooth or roller face breaks or shears off, the load attached will come crashing down. Also the fact there is no simple way to add electrical limits to a system like this, means that any programming mistakes with this will likely result in damages. TL;DR: Yes to you, and sadly no to the design... it is cool though.
@@MinatoAsk "You could either do the pain in the ass over, complicated route, of having all 4 axis running in sync to handle each command if your software will allow it(I've done it on hexapod systems, and it is a lot of math and an absolute pain)," I was actually referring to IK there as it's the only way to run a hexapod system properly. But when there is only one rotational position you are controlling and all axis are at a set relative angle to each other, there's not much reason I see in trying to run IK. Plus I personally wouldn't trust IK in a situation like this for two reasons. Reason one is that this setup looks very prone to running into gimbal lock situations if you're not careful, and in precision systems, you don't want the system you be on the fly making alternate routes to free an axis is that situation. Reason 2 is that there is that with the arm attached, you have fairly defined physical limits that are not axis specific. On most systems with hardstops, you will have electrical or software limits that tell the stage, "stop you are about to go passed your safe limit and hit something". On this, you don't have electrical limits, and as the axis are always shifting orientation, software limits would be very difficult, and risk damaging the the system if something is missed. Plus as I stated in my previous comment, unless you sacrifice one axis to keep a slight opposing force to an axis, you will have unwanted backlash to deal with. While this wasn't really designed with precision in mind, that is just the priorities I have when looking at something like this. Even something not requiring very high levels of precision, like a simple parts picker on a PCB assembly system, that backlash and the wear the teeth will experience over time would make this a no-go in my book. This is just my opinion based on my experience, and the field I'm in. Others with a different background and priorities may look at this differently, but if everyone agreed on everything, the world would be a rather boring place.
@@Poptart133g very well written! Part of learning is learning the hard way first only to find there's easy way to do it, lol! I've deal with servo motor controls before and used IK, so yeah, maybe the alternative is better for this specific project
I was trying for long time to imagine a ball joint that would work like this, but with much more simplified mechanism. This could be revolutionary for robotics!

the main issue with a mobile suit is actually how it is powered. People have crafted power suits but they then have Massive wires coming out the back so they can't move around much.
@@rrteppo The power is needed in order to combine inertia with versatility. Improving strength-to-weight-ratios in all the electrical and mechanical parts could sort that out. So Graphene could probably do it.
I’ll one-up you. Graphene *will* be doing it once the draconian dynasties stops lobbying their pocket-scientists and politicians to file countless fallacious studies regarding the potential toxicity of graphene, and NCT more specifically.
I completely agree with everyone here, the presentation and execution of the project is something to marvel at. The system is mechanically redundant as you have more motors (inputs) than degrees of freedom. Although this shortcoming, I think that this is a wonderful showcase of engineering, and someone will find such an actuator useful someday.
Tbf dual motor/input for single linear/rotary axis are very common in machines as it allows to counteract mechanical backlash of the axis as well as more power without having to resort to a larger motor. Multiple small input gears into one large gear also allows for a larger than normal gearing in a single gear stage as it has more teeth engaged splitting the force (generally its problematic to have a large gear ratio as the teeth strength starts to be a limiting factor).
prosthetic elbows is pretty obvious is it not? 360 degree rotation would actually give amputees MORE freedom of movement than with a normal arm (although unless you're building out of titanium then it will have much less strength to weight)
If both drivers sat on the same plane then I believe that would be the case, however with both drivers mounted at a 90 degree angle then that singularity ceases to exist and also gives the joint a greater range of potential motion.
Amazing mechanism, amazing animation, and amazing music. Wth kind of sorcery is this??! Seriously, my toe was tapping uncontrollably through the whole video...
@@seennotheard8888 As the spherical Gear's teeth is not completely symmetric, there should be a limit of movement at certain angles. Hence I think he added a second drive unit for that reason, and to reinforce strength.
I was very disturbed by the SNAP motion of Driving Module 2 at 1:43, but upon deliberation, this occurs to me to be an animation or motion planning error. The 180 turn was completely unnecessary. So this does not speak against the design. With only two drive motors, one Driving Module, it will only be able to turn the motor around when it's on the singularity. So most of the time, it only has two degrees of freedom, which, figures, with two motors. The ball has 3 degrees of freedom though, and to utilise them fully, here 4 motors are necessary... this doesn't exactly sit right with me. Like, it's basically overconstrained, and it would only work because the tolerances are junk. Then it only gets shown mechanically with only one active Driving Module, and the second being an idler...
This could make an incredibly useful tool for driving and ratcheting. Could also make for an incredible device for cutting, milling, and amazing surgical operations.
You are right about the driving and ratcheting, but not the other uses. There is no way to get any services (cables, power, hydraulics etc) to the output arm, without restricting its motion in such a way that other, simpler solutions can perform the same job.
@@VidarrKerr Yup, that would work, but very low power. Or, and its thanks to your comment that made me think of using energy stored in the ball... Batteries for example.
@@dougaltolan3017 There can be a motor inside the ball too. Imagine that. edit: Think of the centripetal forces and things you could do. Also, look up how car differentials work and apply that to the gears that drive the ball. The possibilities are endless.
No one is going to point out the background music!? It's groovy as heck! Aside from that, I found this very interesting, especially how the different axes were added.
Amazing! Simply amazing! From one engineer to another, this is just so beautiful! And the cross-section literally made me nut! So simple and yet so modular! The usefulness of a ball joint without a ball (and the associated friction) is immense! I mean, do the teeth catch on each other? Is there a lot of shear between the individual bits (especially if they're not metal)?

@@lechatmax8804 If it were modeled in solidworks, this animation where there is animated geometry certainly wasn't modeled in SW. I am a 90th percentile user, meaning I have used most of the program and SW is never displayed here.

@@VidarrKerr Yup, that would work, but very low power.
Or, and its thanks to your comment that made me think of using energy stored in the ball... Batteries for example.
@@dougaltolan3017 There can be a motor inside the ball too. Imagine that.
edit: Think of the centripetal forces and things you could do. Also, look up how car differentials work and apply that to the gears that drive the ball. The possibilities are endless.
Bro this is the best mechanical animation I ever did see on RUclips! I must find out how to do this kind of stuff.
No idea why this was recommended, but wasn't disappointed - go go robo shoulder
Absolutely gorgeous mechanism! Also, great music choice! Love me some IDM
No one is going to point out the background music!? It's groovy as heck!
Aside from that, I found this very interesting, especially how the different axes were added.
Wow, a genuine step into smooth A.I movement
This idea is like the Clockwise-counter clockwise tightening bolt. I'd love to see this work for prosthetics.
This should be installed on the ISS. Canadarm could have a new friend.
Awesome Shoulder and Hip Joint
Dang, this is pretty cool. I'd like to see what come of this in 10 or 20 years
Whoever made this is a great individual
これはすごい球関節が完璧に再現できてる！
構造上モーターは肩の外側でも問題はないだろうし人体の機械化がさらに近くなったで！！

I'm immediately visualizing the applications of this in joints for androids
This is literally what Japan is for. Nice work!!
IF only they wouldn't of screwed up real bad with Fukushima.
Geez that animation was world class!
That is extremely well explained! Very nice invention!
really? You literally made 2 ball joints that turns 360, to make a bigger ball that turns 360? GENIUS!!!
This makes motions much more lifelike, I can see this being used in humanoid robots for shoulder joints and things like that.
I doubt it is too reliable for reasonable load. Viewing it perform with an arm and small load- it did seem like it skipped tooth a few times.
Nice explanation, awesome concept and incredible japanese electro bossa
the explanation looks like something out of a science fiction movie, yet it exists in real life
huge props to whoever desined this. im both fascinated and confused at the same time.
It is probably the dream of every mechanical engineer
this mechanism is really interesting i'm building a replica for my highschool and to show to my studants
Amazing! Simply amazing! From one engineer to another, this is just so beautiful! And the cross-section literally made me nut! So simple and yet so modular! The usefulness of a ball joint without a ball (and the associated friction) is immense! I mean, do the teeth catch on each other? Is there a lot of shear between the individual bits (especially if they're not metal)?
I would guess that it would be in a lubricant further down the track
What a time to be alive.
Would love to see a full robotic arm made with this. The ROM is very similar if not more mobile to a glenohumeral joint
No idea how I ended up here, but this is amazing.
It's fantastic, intelligent and innovative that I lack words to express how great this mechanism is.
The engineer that conceptualize this has so much spare time jeezuz
I can't imagine designer's face when he first time saw project plan sketch
The graphical explanation was amazing. Eventhough I did not major in mechanics I kinda understood the concept.
Very promising tech, countless uses.
mm yes the algorithm
it has it’s ups and downs
but *this* oh my, this is the best i’ve seen
may the algorithm bless you for the veiws and us for the godly content
I'm just imagining this mechanism on a humanoid robot for a shoulder.
Are you "watching" this video in braille? I mean, you wrote that comment using a computer and that pretty much requires you to see it.
@@anteshell I think you hit reply on the wrong comment thread.
and it gets stuck every other motion.
🔴 What Is Islam? ⚠️
🔴 Islam is not just another religion.
🔵 It is the same message preached by Moses, Jesus and Abraham.
🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
🔵 It reminds us that since God created us, no one should be worshipped except God alone.
🔴 It also teaches that God is nothing like a human being or like anything that we can imagine.
🌍 The concept of God is summarized in the Quran as:
📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚
🔴 Becoming a Muslim is not turning your back to Jesus.
🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
@@HaloWolf102 I think you're right. Don't know how that happened. :D
I had a very similar idea around 2012. The start of the concept was an omni directional, spherical, spiked wheel for use in tanks, as an alternative to using a continuous track. I had a different idea for the driving mechanism, though this one is smoother looking.
This is gorgeous and seriously brilliant
This is probably the most satisfying thing I've ever seen. Incredible!
Do this on a larger scale and you got insane Omni-directional wheels
A big carpet of little bobbles to mesh with.
irobot
omni-directional wheels only need 2 dof, this is overkill
@@gralha_ my point still stands
This is one of the greatest things I've ever seen. EVER.
Cutting edge engineering, math and materials. To be used as a advertising flag stand at a used car lot.
or killer robots
Mind-bending. Only the nervous loud noise it makes all the time seem to be an impediment for many applications.
what is the cad and presentation software being used, would be rad to learn!
solidworks
@@lechatmax8804 If it were modeled in solidworks, this animation where there is animated geometry certainly wasn't modeled in SW. I am a 90th percentile user, meaning I have used most of the program and SW is never displayed here.
ギアが球状歯車の回転中心付近に来た時のロール軸のキビキビした動きがなんかかわいい
Looks like this would be the perfect drive system for a force feedback flight stick for simulators :)
Hell, it would be perfect to drive a whole giant robot-arm based full motion flight simulator! :D
Ok this is by far the best use of youtube. My life just improved just watching and learning. I had to subscribe. Awsome.
Just trying to imagine the machinists' face when the engineer presented them this design.
Infinitely many angles, functions, and movements all created from simple angular motion
is it possible to use the output link as an input kind of like a joystick?
Would be interesting to test, I feel like there would be too much torque though. Kinda like trying to turn a gear that's meshed with a worm gear
Also, is this better than current joystick construction?
This is such an elegant design. I'm surprised no one thought of this before.
The fact that one drive can cause the central ball to 'slip' on the other axis means that it really does not have any 'holding' power.... meaning... any real force / torque on the end will cause slippage. But it is a nice design !
First and foremost, this is awesome tech! Just baffled my brain!
Also, the music is equally as cool, please can someone help me identify who the artist is and where i can hear this song/album?
I'm not able to find the source for the song but Moe Shop has quite a bit like this!
@@StormBurnX cheers
Best video on RUclips EVER! I wonder what is the step resolution on the movement of extended arm. Or it is analogous movement. This is really ingenious design and presentation. Thank you for sharing.
