Okay, here's what I saw while watching your demo. You build this full scale, on a long winding track, at an amusement park. The central block is the passenger cabin. It uses the ability to move the cabin around while keeping it level, to dodge various obstacles around the track. Passengers thrill to the "near misses" with things as they zoom along.
That's cool it could be a wizard of oz ride during the tornado an the cabin could be dodging the cows an all the other debris in the storm. I'm not sure if that what you were talking about but I just thought you had a cool idea an threw my 2cents in 😆.
Here's the math if you are interested in... x is the coordinate along the slider pointing to the background, z points upwards. x = 0 is the forefront block. a and b are the distances between the forefront block and the two single blocks, respectively. 2 is an arbitrary coefficient, it's just an eye guess. The forefront block with 2 arms forces the main object to move on the plane: x - 2z = 0 The other 2 blocks force the main object to move on the planes: 2x - 2a - z - y = 0 2x - 2b - z + y = 0 Solving the system yields: x = 2 (a + b) / 3 z = (a + b) / 3 y = b - a So, the concept is: if you want to move the main block back and forth along the slider, you move all the blocks rigidly (that's easy to grab). If you want to move the main up and down (z axis) you move the 2 blocks in the background rigidly towards the back and the the forefront block to the front. See this at 0:08 . If you want to move the main object sideways (along the y axis) you keep the forefront block still and move the other 2 blocks in opposite directions. This is the less intuitive movement. You can see this movement better at 0:02, right at the beginning, and at 0:40 but it's combined with x direction movement so it's not so easy to grab. Have fun.

Extremely good point, this is the opposite of rigid, the shallow cut depths would destroy its efficiency. I don’t see how this is any better than a standard 3axis mill.
@Stein Mauer There's a difference between understanding its kinematics (it's a fairly simple idea from a kinematic point of view) and finding it unimpressive. Deriving 3D positioning from a pair of parallel 1D rails certainly _looks_ impressive. The relationship between the carriage positions and the movement of the end effector is not particularly intuitive, and the result of that and the relatively long jointed arms is movement that many people (including me) seem to find memorising.
I love this kind of innovation/thinking, this may already be a well known setup and I've just never seen it, but if it's not, well done! Your efforts are not unnoticed!
@@sumdumbmick as someone who uses 45° angles at my job everyday, this is not just a simple ole 45° and done thing. This is a lot of engineering, regardless if it was something already made, the quality at least seems better than whatever is coming out of China or the third world in terms of quality and material, and this is just a model.
larger scale, less travel, larger motors. i could see this as part of a ride vehicle motion system…sharpening the feel of a curve, problem with knuckle based is payload limitations…
It's amazing all the technology advancement, precision engineering, and scientific knowledge accumulated over thousands of years just make something that nature creates in a heart beat with no effort at all. With all the impressive things humans are making and it still is insignificant in comparison to what nature can produce.
I saw them right away, then paused and they looked like bolts to me... I ended up running it at .25 speed and saw them jiggling about. I am incredibly happy they are there.
Well, it's actually 3 movements to 3 axis. Quite charming pantograph. Heavy torque on joints. But what is so cool is that those 3 input movements are in one axe.
Awesome design!!!💪🏼 It would be awesome to use this concept to convert a manual milling machine to CNC… I can picture t-slot mounts for attaching the rails and a small vice on top… maybe light use only? Super satisfying to watch!
Nice job. I had a similar idea. Was basically thinking of putting that on the x-axis of a corexy 3D printer, but with the first sled split and a third added for tilt. Should be doable without wasting too much space.
@Unmannedair : That would be interesting. I think that by adding only one more actuator to the mechanism, you will only get tilt on one axis. The equivalent mechanism on a Delta setup is a Stewart Platform, which uses six linear actuators... I haven't seen anything that works using less. ua-cam.com/video/9OikCw-XKKk/v-deo.html
@@PiefacePete46 do you think that would be easier or better than just using a motor as a rotary like in a couple newer cnc kitchen or 247 printing videos? Which ever one is Stephan
@@travistucker7317 : Hi Travis, I enjoy Stephan's videos, but I had not watched some of his more recent ones. I just checked them out, and the rotating angled nozzle is pretty neat! If you are considering experimenting along these lines, that looks like a good starting point, especially as there is help and software already available. My own 3D printing experience is fairly basic, (but very satisfying!). I have an early Ender 3, with a BL Touch upgrade, and really only print things that I want in the workshop like brackets, mounts, knobs, hinges etc.. (I'm retired, the "workshop" is fairly basic! The reason I am familiar with the Stewart Platform is that I used to work for Air New Zealand in the Operations section. On a couple of occasions I got to look around the Douglas DC8, and Boeing 747 flight training simulators. The dummy flight-decks are mounted on six big hydraulic rams (same as a Stewart Platform), which moves to give the sensation of flight. Very impressive and convincing! ua-cam.com/video/RUwsrBkP6NA/v-deo.html
How accurate is the positioning? There’s 50% more joints than in a delta robot, so I’d expect a proportionate increase in sensitivity to slop in the bearings. OTOH, with high-quality bearings here, there could be almost zero play, so could be very accurate. Have you done any measurements or validation on the precision? (Looks super-cool, though, and it seems like you’re getting excellent speed despite the high moving mass.)
I’d also point out the delta pattern seems more suited for a contained up down movement, this thing would be great for a grab and move type machine since you get more lateral distance.
@@danrudmin6797 Thanks for the detailed reply! Ah, “prismatic” was the word I didn’t know for this type of joint; vocab word of the day 👍 Interesting point about the bending moment on the arms vs compression/tension in the delta. I expect you’re right about the cantilever shaft being the weak point in terms of stiffness. OTOH, easy to fix by making the shaft longer and extending the base to support it with another bearing at the top. That would make it very stiff; I suspect at that point that the timing belts would become the next weakest link. (Ball screws! 😆) 45lbs is really impressive(!) Do you have a particular use case in mind, or was this just an experiment/proof of concept? Kudos on the construction, btw; it’s gorgeous!
Hey, I clearly see this has potential at angular imaging, 3D FDM printing and precision bioscience work. Good job. I'll tag this in LinkedIn. Hope you get more visibility.
This looks like a fantastic printer head for new type of 3D printing, or mount for a swiveling laser cutter, or one mount of a flight simulator bracket, depending on how strong (maybe the only mount), or a packaging machine bracket, or auto manufacturing robot arm mount. Probably a lot of uses for this type of mobility if strength included. Bravo, nice bracket you have there.
That would be pretty cool as toolholder, just a bit tricky because the cables or tubes will wear out so fast with all this movement. And seem to only work overhead because of the belts which I assume also run the current to the motors in the bases. I can't think of a practical application really. As a tooling device it would be ok, but its not particularly stable because of the lever action. Neat machine anyways.
OMG! I CAN'T STOP WATCHING THIS! It is so visually pleasing, I can feel every synapse in my cerebral cortex being stimulated. This might be the greatest video in the history of mankind! 👍👍
Very nicely done! Is there logic behind the angles chosen? I understand it is basically the intersection of the 3 plane set forth by the arms. Are shallow angles better or worse? Or is it precision vs force kinda balance?
As a starting point, the angles were all orthogonal. If you imagine a cube angled so that the base belt drive axis direction runs through two opposite corners, then each joint would be aligned with one of the cube edges. So every axis is perpendicular to every other axis. But I modified it slightly for manufacturing reasons. To make the base of the back two arms identical parts, they need to be rotated 90 degrees from each rather than making a left-hand and right-hand version. This means they aren't perpendicular in 3D space, only the XY projection is perpendicular. You could easily mess with the angles of any joint to trade off thrust and resolution for speed and travel range. But I have a gut feeling that orthogonal joint axes will be optimal for most applications.
@@sghuisman Hi mate, I have a design for a dirt bike lift that I would love to have converted to CAD. I have back problems and working on bikes is my passion along with my son. My design gets the bike higher and creates a stable and functional service tool so I don't have to bend over. I can fabricate it but I haven't yet learnt a modern CAD program, would you be interested in doing that? If so, is there a way of a private message on youtube so I can give you my email without broadcasting it? If you're not interested that is totally fine and I hope you have a great day.
This would make pretty cool camera slider. You could probably build smaller/cheaper version with 2020 or 2040 aluminium extrusion, gt2 belts and nema17 stepper motors. 3D printed SLS Nylon or cheaper carbon fiber PLA could maybe work for those arms. Cool project!
I don't think any plastic type material is really suitable for this kind of platform. It will introduce some ability to deform and therefore add vibration and unwanted displacement. Motion systems like these are particularly vulnerable to flexible machine parts. Not everything can be 3D-printed, this is exactly why the designer opted to CNC machine those arms out of aluminium :)
@@MarinusMakesStuff Nylon 12 either carbon or aluminium fill is plenty stiff for this application and payload I'd use. Besides there are plenty of plastics capable of exceeding structural qualities of aluminium while weighing less. The bearings will take most of the beating anyway. But what do I know I've only been printing for 10 years.
@@ex1tium Nylon 66 with a 40% by weight fill of carbon fiber (significantly higher than any 3dp filament) has a modulus of elasticity of 24GPA, around a third of aluminum at 70GPA. With that said, rigidity if often more affected by mechanical design (large cross sectional areas, wide bearing spacing, etc.) than pure material properties.
@@ex1tium You're dreaming. There is currently no plastic that matches or exceeds the mechanical properties of aluminium. If you think there is then site the source and state it's tensile strength. ALU 6061-T6 for example has a tensile strength of 45,000 psi while the strongest plastic PAI has only 21,000 psi. It's impressive but does not compare to aluminium.
Yeah well I wasn't shooting for micrometer precision and 1000kg loads on this thing. I was talking about camera slider with payloads of 1-3kg. What I meant was that nylon would be good enough for my application. I think its pointless to argue about what material is better or stronger without discussing the application you're gonna use it on. Plenty of aluminium parts are being replaced by nylon precisely because they don't need that high tensile strengths, you can design stronger structures impossible to manufacture in CNC and you can save material with additive manufacturing. As for my statement about 'exceeding structural qualities' it was a bit misleading and I wasn't able to describe what I meant well enough. Plastics are getting closer and as I said whether you use plastics or metals depends on the application.
what is awesome is the person in the background that totally ignores the sound of the machine. It's probably one of thousands of runs of it and everyone got used to it, but this one unexpectedly ends up on youtube with millions of views and a jacket on a chair.
Man it's hard to see but there a 3 belts, the two easily visible ones are for the two independent arms that move separate one another, while there is also a hard to see belt in the middle connected to the pair of arms that are connected to a shared base. Man what a wild concept. I'd be curious to know what angles are used for each of the various arms so one could make their own. From the looks of it, it might be 45 degree angles but I'm not entirely sure.
Damn, engineers who invent mechanism like this are awesome aren't they, I've watch alot of those mechanical principle video where it show 3D animation of various mechanism, it's like the engineers can invent all kind of way to convert rotational motion to any kind of motion needed
Really cool, I’m looking at getting into C++ I’m really interested in making software control hardware. Can you tell me what coding language was used in this project? Thank you.
This is running G-code (same as most 3d printers and CNC machines) using an off-the-shelf Zaber controller that's already been all set up for the belt drives underneath.

Here's the math if you are interested in...
x is the coordinate along the slider pointing to the background, z points upwards.
x = 0 is the forefront block.
a and b are the distances between the forefront block and the two single blocks, respectively.
2 is an arbitrary coefficient, it's just an eye guess.
The forefront block with 2 arms forces the main object to move on the plane:
x - 2z = 0
The other 2 blocks force the main object to move on the planes:
2x - 2a - z - y = 0
2x - 2b - z + y = 0
Solving the system yields:
x = 2 (a + b) / 3
z = (a + b) / 3
y = b - a
So, the concept is:
if you want to move the main block back and forth along the slider, you move all the blocks rigidly (that's easy to grab).
If you want to move the main up and down (z axis) you move the 2 blocks in the background rigidly towards the back and the the forefront block to the front. See this at 0:08 .

It’s based on a Laval University patent and UA-camr Nicholas Seward also had a similar design idea: m.ua-cam.com/video/oBBhVcemVHc/v-deo.html
@Stein Mauer In a way you wouldn't understand
@Stein Mauer bruh tf 💀
@Stein Mauer bc the top stays level with the ground
@Stein Mauer There's a difference between understanding its kinematics (it's a fairly simple idea from a kinematic point of view) and finding it unimpressive. Deriving 3D positioning from a pair of parallel 1D rails certainly _looks_ impressive. The relationship between the carriage positions and the movement of the end effector is not particularly intuitive, and the result of that and the relatively long jointed arms is movement that many people (including me) seem to find memorising.
Incredible! Fantastic work!!
I love this kind of innovation/thinking, this may already be a well known setup and I've just never seen it, but if it's not, well done! Your efforts are not unnoticed!
yes, nobody's ever used a 45 degree angle before... such amaze.
@@sumdumbmick as someone who uses 45° angles at my job everyday, this is not just a simple ole 45° and done thing. This is a lot of engineering, regardless if it was something already made, the quality at least seems better than whatever is coming out of China or the third world in terms of quality and material, and this is just a model.
larger scale, less travel, larger motors. i could see this as part of a ride vehicle motion system…sharpening the feel of a curve, problem with knuckle based is payload limitations…
It's amazing all the technology advancement, precision engineering, and scientific knowledge accumulated over thousands of years just make something that nature creates in a heart beat with no effort at all.
With all the impressive things humans are making and it still is insignificant in comparison to what nature can produce.
so happy this got recommended how incredible to see these feats of engineering
Yes, YT and social media really needs to promote these kind of things more to inspire more people in science and engineering.
Took me a second to catch the googly eyes. Awesome work dude.
I saw them right away, then paused and they looked like bolts to me... I ended up running it at .25 speed and saw them jiggling about. I am incredibly happy they are there.
Very nice. Looks quite rigid too.
Such complex movements from a very simplified but elegant design is just beautiful.
This is engineering at its best.
101% agree
Well, it's actually 3 movements to 3 axis. Quite charming pantograph. Heavy torque on joints. But what is so cool is that those 3 input movements are in one axe.
My algorithm is spot on today. Love it. Nice work.
First upload from this channel in 13 years and it pops off a million views 😩💦💦💦 go off king
Awesome design!!!💪🏼 It would be awesome to use this concept to convert a manual milling machine to CNC…
I can picture t-slot mounts for attaching the rails and a small vice on top… maybe light use only? Super satisfying to watch!
VERY light use only. There's no rigidity in that mechanism. It'll vibrate like a tuning fork under any useable load.
There are already servo kits for that conversion. Much better
Too much torque on joints
Nice job. I had a similar idea. Was basically thinking of putting that on the x-axis of a corexy 3D printer, but with the first sled split and a third added for tilt. Should be doable without wasting too much space.
Would like to see that sketched up
Insert the Lebron lying meme: “I had a similar idea” 😂
@Unmannedair : That would be interesting. I think that by adding only one more actuator to the mechanism, you will only get tilt on one axis. The equivalent mechanism on a Delta setup is a Stewart Platform, which uses six linear actuators... I haven't seen anything that works using less.

@@PiefacePete46 do you think that would be easier or better than just using a motor as a rotary like in a couple newer cnc kitchen or 247 printing videos? Which ever one is Stephan
@@travistucker7317 : Hi Travis, I enjoy Stephan's videos, but I had not watched some of his more recent ones. I just checked them out, and the rotating angled nozzle is pretty neat! If you are considering experimenting along these lines, that looks like a good starting point, especially as there is help and software already available.
My own 3D printing experience is fairly basic, (but very satisfying!). I have an early Ender 3, with a BL Touch upgrade, and really only print things that I want in the workshop like brackets, mounts, knobs, hinges etc.. (I'm retired, the "workshop" is fairly basic!
The reason I am familiar with the Stewart Platform is that I used to work for Air New Zealand in the Operations section. On a couple of occasions I got to look around the Douglas DC8, and Boeing 747 flight training simulators. The dummy flight-decks are mounted on six big hydraulic rams (same as a Stewart Platform), which moves to give the sensation of flight. Very impressive and convincing! ua-cam.com/video/RUwsrBkP6NA/v-deo.html
Круто держит параллельно горизонтально плоскость, впечатляюще!!!!!
Естественно держит,он же на направляющих
What an excellent robotic bone demonstration. I'll take em all
Honestly awe inspiring and terrifying at the same time.
I feel like this would work well for 3d printing also just a cool mechanism
I see this being used as a type of cargo transport platform between two very tall and large shelves
I'm not sure. Take a look at the space requirements. Also the rigidity will be a problem. But nice concept!
How accurate is the positioning? There’s 50% more joints than in a delta robot, so I’d expect a proportionate increase in sensitivity to slop in the bearings. OTOH, with high-quality bearings here, there could be almost zero play, so could be very accurate. Have you done any measurements or validation on the precision?
(Looks super-cool, though, and it seems like you’re getting excellent speed despite the high moving mass.)
🤓🤜 *NERDS UNITE* 🤛🤓
I’d also point out the delta pattern seems more suited for a contained up down movement, this thing would be great for a grab and move type machine since you get more lateral distance.
@@danrudmin6797 Thanks for the detailed reply! Ah, “prismatic” was the word I didn’t know for this type of joint; vocab word of the day 👍
Interesting point about the bending moment on the arms vs compression/tension in the delta. I expect you’re right about the cantilever shaft being the weak point in terms of stiffness. OTOH, easy to fix by making the shaft longer and extending the base to support it with another bearing at the top. That would make it very stiff; I suspect at that point that the timing belts would become the next weakest link. (Ball screws! 😆)
45lbs is really impressive(!) Do you have a particular use case in mind, or was this just an experiment/proof of concept?
Kudos on the construction, btw; it’s gorgeous!

Dat some crazy smooth movement on all planes, what a design
This thing is AWESOME and with no heim/ball joints
Hey, I clearly see this has potential at angular imaging, 3D FDM printing and precision bioscience work. Good job. I'll tag this in LinkedIn. Hope you get more visibility.
This looks like a fantastic printer head for new type of 3D printing, or mount for a swiveling laser cutter, or one mount of a flight simulator bracket, depending on how strong (maybe the only mount), or a packaging machine bracket, or auto manufacturing robot arm mount.
Probably a lot of uses for this type of mobility if strength included.
Bravo, nice bracket you have there.
Wow. Seems pretty compact. I kinda wonder how stiff the business end at the top is
boioioioiiioioing!
And wether the geometry of the platform XYZ give rise to annoying mathematics and round corners.
This is the sickest victory animation I’ve ever seen
Why does this look so awesome
Combine this with a pan and tilt mechanism on the indefector and this would be an incredible camera motion system
I can see this being used in animatronics for movies, themes parks etc. So smooth!
That would be pretty cool as toolholder, just a bit tricky because the cables or tubes will wear out so fast with all this movement. And seem to only work overhead because of the belts which I assume also run the current to the motors in the bases. I can't think of a practical application really. As a tooling device it would be ok, but its not particularly stable because of the lever action. Neat machine anyways.
space walk third hand helper ?
OMG! I CAN'T STOP WATCHING THIS!
It is so visually pleasing, I can feel every synapse in my cerebral cortex being stimulated.
This might be the greatest video in the history of mankind! 👍👍
yikes
That is an awesome camera slider!!
Very nicely done! Is there logic behind the angles chosen? I understand it is basically the intersection of the 3 plane set forth by the arms. Are shallow angles better or worse? Or is it precision vs force kinda balance?
As a starting point, the angles were all orthogonal. If you imagine a cube angled so that the base belt drive axis direction runs through two opposite corners, then each joint would be aligned with one of the cube edges. So every axis is perpendicular to every other axis. But I modified it slightly for manufacturing reasons. To make the base of the back two arms identical parts, they need to be rotated 90 degrees from each rather than making a left-hand and right-hand version. This means they aren't perpendicular in 3D space, only the XY projection is perpendicular.
You could easily mess with the angles of any joint to trade off thrust and resolution for speed and travel range. But I have a gut feeling that orthogonal joint axes will be optimal for most applications.
@@sghuisman Hi mate, I have a design for a dirt bike lift that I would love to have converted to CAD. I have back problems and working on bikes is my passion along with my son. My design gets the bike higher and creates a stable and functional service tool so I don't have to bend over. I can fabricate it but I haven't yet learnt a modern CAD program, would you be interested in doing that? If so, is there a way of a private message on youtube so I can give you my email without broadcasting it? If you're not interested that is totally fine and I hope you have a great day.
@@craigdavies8099 hi Craig, I’m just an amateur so no way I can do that. I would if I could… good luck with your project.
This would make pretty cool camera slider. You could probably build smaller/cheaper version with 2020 or 2040 aluminium extrusion, gt2 belts and nema17 stepper motors. 3D printed SLS Nylon or cheaper carbon fiber PLA could maybe work for those arms. Cool project!
I don't think any plastic type material is really suitable for this kind of platform. It will introduce some ability to deform and therefore add vibration and unwanted displacement. Motion systems like these are particularly vulnerable to flexible machine parts. Not everything can be 3D-printed, this is exactly why the designer opted to CNC machine those arms out of aluminium :)
@@MarinusMakesStuff Nylon 12 either carbon or aluminium fill is plenty stiff for this application and payload I'd use. Besides there are plenty of plastics capable of exceeding structural qualities of aluminium while weighing less. The bearings will take most of the beating anyway. But what do I know I've only been printing for 10 years.
@@ex1tium Nylon 66 with a 40% by weight fill of carbon fiber (significantly higher than any 3dp filament) has a modulus of elasticity of 24GPA, around a third of aluminum at 70GPA.
With that said, rigidity if often more affected by mechanical design (large cross sectional areas, wide bearing spacing, etc.) than pure material properties.
@@ex1tium You're dreaming. There is currently no plastic that matches or exceeds the mechanical properties of aluminium. If you think there is then site the source and state it's tensile strength. ALU 6061-T6 for example has a tensile strength of 45,000 psi while the strongest plastic PAI has only 21,000 psi. It's impressive but does not compare to aluminium.
Yeah well I wasn't shooting for micrometer precision and 1000kg loads on this thing. I was talking about camera slider with payloads of 1-3kg.
What I meant was that nylon would be good enough for my application. I think its pointless to argue about what material is better or stronger without discussing the application you're gonna use it on.
Plenty of aluminium parts are being replaced by nylon precisely because they don't need that high tensile strengths, you can design stronger structures impossible to manufacture in CNC and you can save material with additive manufacturing.
As for my statement about 'exceeding structural qualities' it was a bit misleading and I wasn't able to describe what I meant well enough. Plastics are getting closer and as I said whether you use plastics or metals depends on the application.
Nearly perfect 3DMax plug rendering! Probs! Just a small frame drop ant 0:12. Good job :-)
what is awesome is the person in the background that totally ignores the sound of the machine.
It's probably one of thousands of runs of it and everyone got used to it, but this one unexpectedly ends up on youtube with millions of views and a jacket on a chair.
Looks like a robo-frog, impressed all the way through. Belts, complexity, precision, coreografi
What applications is this being considered for?
It's mostly for being shown on UA-cam
This would also be great for slow-motion shoots where you need fast, precise movements at high framerates

Man it's hard to see but there a 3 belts, the two easily visible ones are for the two independent arms that move separate one another, while there is also a hard to see belt in the middle connected to the pair of arms that are connected to a shared base. Man what a wild concept. I'd be curious to know what angles are used for each of the various arms so one could make their own. From the looks of it, it might be 45 degree angles but I'm not entirely sure.
i suspect its 45 degrees aswell, but im not entirely sure with the back arm
@Helperbot 2000 I think it's 45 degrees as well for the rear arms, just 45 degrees to a different side or axis of the moving base at the top
not 3 belts, there are 4 belts. one belt per "foot". you just cannot see the 4th belt because of the camera angle the video is shot at.
@@orion7741 no, the front two are connected together, its 3 belts
Thank you! I was looking for the third belt and your comment helped me find it.
We need more. I want to see what precision movements it can do.
Damn, engineers who invent mechanism like this are awesome aren't they, I've watch alot of those mechanical principle video where it show 3D animation of various mechanism, it's like the engineers can invent all kind of way to convert rotational motion to any kind of motion needed
This could be very useful for railway work or automated complex manufacturing, bravo
You actually genius idea
Or for something useful like sweet Halloween animatronics 😂.
Railway applications are absolutely genius. Nice work 👍
Really cool, I’m looking at getting into C++ I’m really interested in making software control hardware. Can you tell me what coding language was used in this project?
Thank you.
This is running G-code (same as most 3d printers and CNC machines) using an off-the-shelf Zaber controller that's already been all set up for the belt drives underneath.
Awesome, thanks for the reply! Shameless plug😅I am currently a cnc programmer at aerospace company and I am currently leasing a Hurco cnc mill from a friend of mine. when not at work, I machine all sort of components for individuals and companies. If you or anyone you know needs cnc machined components I would love to be of assistance.
@@danrudmin6797 Can you do real-time control of the machine using a Zaber controller?
@@Skooteh That kind of depends on what you mean by real-time. The controller logic and motor drivers are acting in real time. The communication from my computer to the controller is not real-time.
That movement is so cool
That’s a beautiful sight!!! Congrats!
After Peloton, this maybe my next exercise machine.
Less materials, same function. Cheaper and more efficient. Always a nice upgrade.
Unreal. Seems like a useful mechanism.
13 años sin subir un video y llegas al millon 👌😎

This is great because of its simple build and failure-free
Not sure what I just watched but it's so cute!
How a great idea can change the fate of a YT channel. 🎉😊
Exelente trabajo!,gran velocidad!.👏👏👏👏
Very nice. I've made one in CAD before but never built it
No idea what it is for and why it was built but that said, the uniformity and structure of its movements, is really cool
0:45 "Ayo checkout this" 😂😂
Did I just get stick bugged? LOL
The googly eyes were a great touch.
But in all seriousness, this looks like an extremely complicated and advanced piece of technology, but I have no clue what it is trying to accomplish.
Good job on your thing.
holy hell thats beautiful
I pictured a happy face on that top block the whole time it was putting on its best moves. Also I'm very interested in camera sliders so that was my point of reference in thinking what purpose this mechanism has.
This is amazing and beautiful... Put googly eyes on it
Look at this little guy dancing, he's so happy!
Triperton breakdancer. Nice job!
Nice.
There are a lot of possibilities with that there contraption!
I think we are looking at it upside down.
Beautiful piece of work! XYZ, two more axis to go...
oh right !. the engineer mating dance
Looks like it’s from the year 2362, sounds like a 1980’s printer. I love it.
Converting linear motion off axis to full 3D motion. Nice
Симпатично. Сначала показалось, что это на линейных двигателях, аж восхитился!
well done 👍 this will solve an ongoing problem for someone somewhere.
very nice! we use same actuators on robot transitions - but never thought to do this!
BEAUTIFUL 😍
Gives me the motivation to start my push-ups again 😁
nice upward motion and speed for a bottom clamping/pallet preposition application at first glance. for high accuracy you could use something like this as a preposition offset to correct pallet variations…or to index between stations in a cell…
This is going to be so useful next year when I try keeping those trick or treaters from taking more than one candy.
