What is it you ask? A Gough-Stewart platform is a type of parallel robot that has six prismatic actuators, commonly hydraulic jacks or electric actuators, attached in pairs to three positions on the platform's base plate, crossing over to three mounting points on a top plate. Devices placed on the top plate can be moved in the six degrees of freedom in which it is possible for a freely-suspended body to move. These are the three linear movements x, y, z (lateral, longitudinal and vertical), and the three rotations pitch, roll, & yaw. The terms "six-axis" or "6-DoF" (Degrees of Freedom) platform are also used, also "synergistic"
Excellent work! I have a similar design coming up soon in Fusion 360. I'll be using off-the-shelf linear actuators and u-joints though. However, following your steps in the video will make my life easier. Thanks again for such a fantastic walk-through.
If I may ask, why did you add revolute joints between the end plates and the u-joints? I believe there is no revolution required at these joints, or am I wrong? However, my model did not move when I had these as rigid joints. But I was able to move the top platform freely before adding the last linear actuator leg. I replaced these with revolute joints and I was able to move the platform again with all legs connected.
That's because the model wan't 100% accuracy enough. I think I am talking about serveral mm of error at the joins that avoid the rotation... that was something weird. At the end I just end up using the solution you see in the video!
Thanks Javier! I found a paper explaining this. Looks like at least one of the joints per leg should be a spherical joint, i.e. universal joint + revolute joint. www.scielo.br/scielo.php?script=sci_arttext&pid=S1678-58782012000200011
Awesome, that explains everything. It's curious when you are dealing with some design you start to discover some design patterns and features for your own. Thanks you man, really interesting to learn about.
good job, dude! But I'll give you 2 tips. 1. you should use fitting places to assembling process. It's so easy to add a cylindrical cut on platforms to corradial mate. It even can be with different radius because cylindrical mate works with the center of the circle. 2. Keyshot can place labels better than PS.
Hi Javier, Really nice modeling work. It's amazing so much was available in Fusion 360 back in late 2015. I've only used the rendering features a couple of times, but you got me thinking I should use it more. Best wishes, Kent
Thanks for your comment. Yeah Fusion 360 is really awesome. In this current model I used Keyshot for the final render, however the render inside Fusion 360 is getting better and better in every version. Fusion 360 is a really powerful CAD tool, so the people that are working in the current development are putting some many efforts in other parts of the tool such as CAM, drawings, simulation, etc.. Of course, I only care about the modeling part of it, that its growing bit less that others :-(
Have you looked at scripting in Fusion 360? I've tinkering with that today because the motion study interface is pretty limited. I'm using the Python interface, but looks like other languages are supported. I thought I knew someone who worked on KeyShot, but realized it was Bunkspeed, but then read KeyShot came from a split at Bunkspeed? I see you do ZBrush work as well. So many great programs out there today.
You are right, there are so many! Now, I am interested in SideFX Houdini, it's so powerfull and flexible. If you don't find something by default just make it by yourself. Also it supports Python scripting and Wrangle language, that it's like dealing with GLSL shader language in OpenGL. I really recommend you.
Yeah, that's a similar definition that you can get from Wikipedia. However, you can use for other purposes like as a neck for a Robot or a platform for motion capture in movies.
I don't remember exactly. Maybe five hours or so, it is basically repeating the same components over and over. The trick is that you have to know how to use the tool very well and extract those components into your mind before start.
Beautifull work ! How did you manage to copy the pods with the jonts ? When i copy / paste new a componment the joints are not copied so i have to recreate them .. Very embarassing .. Thx for the help !
jpdesvals I cannot remember, i think i used a component with all joints set and use just like you said the copy and paste method. However you can model it in a separate file and import it as an isntance. sorry man, hope this helps
Just look for Hexapod Systems through UA-cam and Google to look for for motion, assemblies and components. Of course there are some touches and details from myself, for the rest it's entirely functional.
Wow. That looks absolutely amazing! Would you be willing to make a in-depth tutorial on how to make this hexapod design? I noticed that you brought in some files from your SAMPLES folder like "sdcrew11" and cillindrival v4 v1". Are they your own design as well? If soWould you be willing to make a tutorial of them as well? Love the video!
I have downloaded the screw model from grabcad, I think so. But it's so easy to build for your own. The other one is for a Kitbashing folder I have. I would like to do some videos tutorials but I have to get some time to do the post-produciton etc..
How would you export the pieces to be animated in another package ? That may sound like a dumb question, it's the workflow I have in mind that contradicts with the workflow in Fusion.
There is no way to export the animation with bones or anything. There is an option using your Web Autodesk 360 account that allows you to export the model into FBX format. However, there is only the geometry, nor the materials or the animation. Sorry man! :(
One could export each piece as FBX to be animated in another 3D package if desired. Can I ask if you can simple post a screen capture of this Hexapod exported to polygons a strictly all quads, it doesn't matter what angle ?
Hey I come from a maya background but am interested in learning fusion360. How are you getting it to move the way it does at 9.05 ? is it some sort of rigging system where you're parenting pieces to other pieces or does it work some other way? Thanks!
Take a look at the ASSEMBLE section in MODEL view. You can add as many as-built joins and joints you want. Both types of joints are very powerfull and very simple to apply to components. There are plenty of tutorials about this topic. I prefer as-buildt joints, however some times you would need the other ones depending on the complexity of you model.
ttt w basically internet and intuition, knowing how pieces are done. And also the workflow to use. Each person decide this workflow, ie starting from sketches, basic shapes, putting all together, refining, etc.. it depends on your skills and speed
Hi man! There are a lot of tutorials at the offical "Autodesk Fusion 360" channel. Start firstly with the Seminars. In those there are a lot for tips for Beginners. After those tutorials you will have to keep working, working and working.... XD
As someone just learning fusion 360 This is damn impressive!
Mad skills! How long had you been drawing CAD before you were able to be this good?

Vilen Saatsazov thanks! Some amazing improvements in tools. This video is kinda old right now.
bro, this is sick!
Niceeeeee🔝😝
Stunning
great F360 modeling skill, thx for post
How long in real life
Inspirational work man!
buen diseño.... excelente video
Gracias Carlos!

Absolutely crazy! Wow!
awesome man most motivational video
Exceelent
What would this be used for? What's its application? Great video by the way.
It's called a Stewart platform and a typical use would be for aircraft cockpit simulators.
Yeah, that's a similar definition that you can get from Wikipedia. However, you can use for other purposes like as a neck for a Robot or a platform for motion capture in movies.
Si molto bello. Ma a cosa serve?
Master!! Awesome!!!
Very nice model! Would you also do the same video at a slower speed? I really like what you've done but had a hard time keeping up.
you can actually slow down the speed in youtube, go to the settings option in the video and change the speed to whatever you want :)
How long did all this take you? So impressive!

Keyshot can do really good labels.
yeah, you are right but I really like use photoshop for that!
Thank you for inspiring video! :)
wow ! thats so great !
thanks man!
Did you have a schematic for this? How did you know what each component looked like on such a detailed level?
Just look for Hexapod Systems through UA-cam and Google to look for for motion, assemblies and components. Of course there are some touches and details from myself, for the rest it's entirely functional.
Thanks; excellent work!
Just Wow!!!
very nice work!!!
I can't seem to import an assembly and have its joints work. I have to put each assembly together from scratch... Help what am I doing wrong
Wow. That looks absolutely amazing! Would you be willing to make a in-depth tutorial on how to make this hexapod design?
I noticed that you brought in some files from your SAMPLES folder like "sdcrew11" and cillindrival v4 v1". Are they your own design as well? If soWould you be willing to make a tutorial of them as well?
Love the video!
I have downloaded the screw model from grabcad, I think so. But it's so easy to build for your own. The other one is for a Kitbashing folder I have. I would like to do some videos tutorials but I have to get some time to do the post-produciton etc..
Lack of space for hydraulics ?
Yeah
How would you export the pieces to be animated in another package ? That may sound like a dumb question, it's the workflow I have in mind that contradicts with the workflow in Fusion.
There is no way to export the animation with bones or anything. There is an option using your Web Autodesk 360 account that allows you to export the model into FBX format. However, there is only the geometry, nor the materials or the animation. Sorry man! :(

This is sick
This AMAZING.
Awesome!!!
Nice video.... but that music until the 4th minute sounds like it's made by a tone deaf producer...
was thinking the same thing XD Awesome video tho!!!
free music

How many hours did it take to make ?
Hi Dhruv, I cannot remember right now. I suppose about 7-8 hours long, form start to finish.
That's awesome. Do you do this for a living?
I work as a freelancer. However I really like to pick Jobs related to Product Design.
Where or what resources did you use to learn Fusion 360?
ttt w basically internet and intuition, knowing how pieces are done. And also the workflow to use. Each person decide this workflow, ie starting from sketches, basic shapes, putting all together, refining, etc.. it depends on your skills and speed
Javier Santos were there any websites or UA-cam videos that were especially beneficial for you to learn?
Awesome
Is your own library?
It's just a Samples folder with Tests
Javier Santos where i get library like a inventor?
No idea man! In some CAD webpages you can grab some models for free.
I just started learning fusion, any good beginner tuts ?
Hi man! There are a lot of tutorials at the offical "Autodesk Fusion 360" channel. Start firstly with the Seminars. In those there are a lot for tips for Beginners. After those tutorials you will have to keep working, working and working.... XD
Nice
not a hexapod. it's called a stewart platform.
Drum bum you,re right man! thanks for the hint
Wow!
A beginner like me will gain little from this complex video, even at 1/4 speed. Nice work though.
Very Very naaais!
very cool :)
But it is pretty good for you
wtf happened to the music and the composer...... like fuck music theory
конструктор, не нюховший пороха
REALLY bad mix
Horrible music...
I can do better
no you can not
Awesome
