exactly!!!!!! I want to see it in action!!!!

@@stefans.8027 Stay tuned, hopefully I will have some time to make a sequel soon!! 😊

I will have to get a bit of work done to show it off, but hopefully I will be there soon!!

@@swannschilling474 , I'm looking forward to it!

@@swannschilling474 I dont even know what this does I just wanted to see the mechanism to see

There is a 1:10 reduction ratio on each motor, so hopefully they will produce enough torque...I will hopefully get to do some precision and stress testing soon! 😊

@@swannschilling474 Good work! Waiting for the results :)

@@jaggar28 I am almost there, just some more tweaking and I will be ready to show the actuator in action!! 😊

Thanks a lot, still some work to do on the software side...but slowly getting there!

@@swannschilling474 so what can u do with it?

@@miclairmiclair876 It will be the end effector for my robotic arm, but it could also be a camera gimbal or a rocket thruster as someone recommended! 😁

@@swannschilling474 sweet I love it. I go ahead and subscribe. I forgot to, sorry

@@miclairmiclair876 thanks a lot!! Its really nice to see you being interested!! I will try to post more on this soon! 😊

Thanks a lot!! I will try to show it as soon as possible! 🤞😊

The new video is up...just in case you missed it!!

Thanks Will!! 🤗🤗🤗

That is actually what I had in mind when designing it...I will try to create more content on building the arm as I go!! 😊

I've been trying to design a robotic arm for about the past week myself, the fact that this was recommended to me now is insane! This really is an amazing design!

@@inconspicuoususername Hey, that is so cool!! Nice to be connected!! 🙂 I am actually building a robot arm myself and the good feedback on my design will make me definitely post more content!!

@@swannschilling474 I've already subscribed and can't wait to see more, but I'm afraid I won't be able to supply any meaningful feedback! I'm no engineer, and my design is relatively primitive and only meant to be hypothetical, really. I didn't even know what I was trying to design was called a spherical parallel manipulator until I found this!

@@inconspicuoususername Awesome!! So crazy it was still recommended to you right? 🙂 I will try to post more on this subject soon!

Thanks a lot!! I will try to put up more content soon!! 😇

I was the same. Really complicated thing with no idea what it is. 😂

@@MekazaBitrusty it is just a spherical joint, like a wrist or neck! It could also be used as a gimbal for a camera! 😊

Thanks a lot, happy to hear that you enjoyed the build!! 😊

Thanks a lot!! I am happy you like it!! Will make more content on this soon!! 😊

Thanks!! It was really fun to build!!

@@swannschilling474 is there someone I could message you ? I had a few questions about the motors your recommended

Thanks a lot!! Glad you like it!! Stay tune for more updates!! 😊

Thanks a lot!! I am super happy about the positive feedback!! I will put out more content like this soon, so stay tuned!!

Thanks a lot!! Happy to hear you enjoyed the assembly!!

Are you planning on doing any software tests in the future? Would be super keen for it!

@@SakaScribbles Yes I will!! Hopefully I will get to create more content on this actuator soon! 😊

@@swannschilling474 Amazing! Can't wait!

Thank you so much! The files for printing are available if you're interested to build one yourself! 😇

Thanks a lot!! Glad you like it!! I will post more content on this actuator soon! 😊

Thank you so much!! 🤩

They are just little inserts that hold the bearings im place...the design works well, but I am about to design V2. Let me know how everything is working out for you! 😊

Thanks a lot!! Happy to hear you like it!!

Thanks!! Glad to hear you enjoyed the build!! 😊

Thanks, I am glad that you like it...hopefully I can put out some more content on this actuator soon! 😊

@@swannschilling474 subscribed, keep up the content!

Thanks a lot for supporting the channel!! Glad to hear you liked it!! 😊

Thanks a lot! I am really happy this seems to be of interest!! 😊

It is just the ratio of the gears attached to the motor axis and it corresponds 1:10 in ratio to the disks number of teeth! 😊

Thanks a lot!! 😊

It could in theory be connected to the outside ring as the reduction ratio is 1:10 but it would also increase the overall size of the design...why do you think it would have more accuracy than being placed directly on the axis? Let me know your thoughts on this! 😊

Hahaha, glad you like it!! Its my favorite screw driver!! 😁

The kinematics will not be easy on this one, but an SPM is a generic joint so there is a lot of info out there on how to drive it!! Stay tuned!! 😊

It is backdrivable exactly like you said!! 😊

Hahaha, thanks for watching the video to the end and for this idea!! 😂😂😂 Yes it just barely fits!! 😂😂😂

Nice!! Please share!! I would be very interested!! 😊

That is actually a legit point, for something with a wide base this would cause a problem! But I build my gripper in a way that there is enough room, so in my case there are no issues! There are a lot of SPM design possibilities out there and it is always a good idea to adjust them to your needs... and yes one of mine was to make it look cool! 😁

@@swannschilling474 Well it does look cool for sure, so good job.

Thanks a lot...I hope I will be able to show somemore progress on the full arm soon! 😊

@@swannschilling474 I am thinking of a humanoid robot waist would be quite perfect with mechanism👍🤔

Thanks a lot I am glad you enjoyed it!! 😊

Thanks a lot, I am happy you like it!! I will try to create more content on this actuator soon!! 😊

They are reading the positions from the embedded magnets in the shaft ends. I used optical encoders on my Cycloidal Gearbox, they are super robust!

Happy you enjoyed the build!! 😊

I am glad that you like it! I hope I will have the time to build V2 sometime soon! 😊

Thanks, it is build on my old trusted workhorse the Prusa i3 MK2, great printer!! 😁

Thanks a lot for your positive feedback!! Glad you enjoyed it!!

Ha, you caught me!! 😁 I am actually not happy with the way I fixed the magnets...they are glued in and I would like to fix that in the future! That is why I skipped the mounting! 😋 Happy you took the time to observe closely!! 😊

Hey, thanks for your interest in my design!! The Orbita joint was one of my inspirations for building this...I will most likely release the files, but it is still early development so I will have to sort out some stuff before I do!! So stay tuned and enjoy!! 😊

Thanks, how is your Inmoov doing? 😇

@@swannschilling474 waiting for filament .doin the waist .

@@EDP1 Great to hear you are progressing!!

Hey, this joint is supporting unlimited rotation, since the reduction ratio is 1:10 it should work without an extra encoder...you can use a slipring to prevent cables to tangle up! But I will have to put some work in and see how far I can push this!

It is my swing on this actuator, but it is not my invention!! Check the Parloma Hand or the Orbita joint by Pollen Robotics for more actuators like this one! 😊

Thanks a lot! Stay tuned for more content, the github page for the boards firmware is in progress... Please feel free to share my video!

@@swannschilling474 ohhhh，This is my first time I have received a reply in KZfaq.I subscribed your channel.🥳

@@user-qx9el8fx2k Happy to hear I am the first one!! And thanks for subscribing!! 😇

It is supposed to be the end effector for my robotic arm! It transforms the three vertical axis into a 3DOF spherical joint!

Thanks a lot for your positive feedback! Yes it is my design, the PCBs were custom made by my friend, he is also writing the firmware!! 😊

This will be the next task to tackle!! I will keep the channel update! 😊

I will try to post a sequel asap, but I still need to get a few flaws sorted out...but making good progress!!

The PCBs are custom...but I also made a version of this joint using standard AMS encoders, it is slightly bigger because those do not fit on the top layer and need separate encoden layers! 😊

@@swannschilling474 Shall i ask if you are going to opensource them ? :)

@@mihaim2 I will most likely do so...but will still need to sort out the final tweaks in the design! So stay tuned!! 😊

@@swannschilling474 I am , I am :)

Hey, the design is two years old now and the motors became quiet expensive. So there would need to be some remodeling and also I never finished the custom PCB...but if you are curious and would like to work on the design you can find the files over here www.printables.com/model/323998-spm-3d-printed-spherical-parallel-manipulator

It will be the wrist for my robotic arm, but it can also be used as a camera gimbal...I will upload more content on usecase scenarios, so stay tuned! 😊

Its being printed on my old workhorse the Prusa i3 MK2, never failed me in years!! 😁

Thx glad you enjoyed it!

@@arunchandran5081 Not really but could be used for this purpose!

Funny! I was looking at your channel this morning! 😇 There are a few things that I would like to change...but the gears are working fine actually! I am trying to figure out the inverse kinematics atm and I am stuck! Did you get the math done?

@@swannschilling474 it's been a bit since I've worked on it. There is a good paper I may have... somewhere but the short answer is no, I don't have the kinematics worked out yet.

@@colbertbd let me know if you find that paper! I am having a github repo, if you would like to take a look you can check my progress. I am kinda stuck on the inverse kinematics... github.com/SwannSchilling/SPM_Kinematics

Yes I am planning to do so, and the good feedback on my design get me very motivated! Thanks a lot for the positive feedback!! 😊

The new video is up...just in case you missed it!!

Thanks a lot, I am just super happy that my design get such a positive response!! 😊 The tracks name is... Like That - Anno Domini Beats Super happy that you like it, its kinda hard to find good music to use!!

I will push more updates soon and will most likely release the .stl files! But I still need to do a bit of tweaking! The bearing sizes will not change, I can look them up so you can already order them from China?

@@swannschilling474 Yeah, i'd like to order them now! :) So it would be great if you can send me the bearing sizes (or types) Do you have an ETA on when you're releasing the .stl files? Thank you so much!

Hey, thanks a lot for your interest in my project!! 😊 There are a lot of different ways to tackle this problem, mine is for a robotic application...so there are probably more easy ways to design a gimbal! The board I am using is very cheap and also you can use its firmware, you dont need to flash it like I did! Would that be a good starting point?

​@@swannschilling474 Thanks for your advice! I'll look forward to the result.

Thanks for the positive feedback!! 😊

Thanks a lot for your interest!! You can find the hardware used in the description...also there is a follow up video showing the actuator in action!!

I am using it as end effector for my robot arm..you could use it as a gimbal, or a centered rotational point when observing things with a microscope etc.

@@swannschilling474 Someone else did a video on using it for microscopy. That's what got me to yours. I was going to comment on your other video that I was really hoping you'd use the accelerometer/gyro in the ps4 controller to mimic the orientation of it but I have no idea how nicely Unity on linux plays with PS controllers. Usually everyone says "get an xbox controller instead". Do you think Unity is the best choice for linux? I have a lot of things I need visualization for but so far I've been using the xorg libraries straight. Its a PITA. I've been considering Godot.

Hey, thanks for taking interest in my design! I will most likely release the files once I got the final version, there are still a few minor tweak that I will need to sort out So stay tuned!! 😊

@@swannschilling474 awesome :) and I understand that :) looking forward to the final version. keep up the awesome job :)

@@enricotempert I will keep the channel updated with more content and info about the availability of the print files!

Sorry I just now read the info in the description. Not meaning to rush you on the files

@@vaughnmonkey Thanks for taking the time to read the info!! Hopefully I will have time to work on more content about this soon! 😇

@@swannschilling474 I thought it looked something like that. Im studying to be an automation technologist, so its in my ballpark. Ill sub and follow your projects :)

@@magnuswf Sweet!! I will try to update the channel with more content soon! 😊

Which bearings are you talking about? Let me know if I need to fix a mistake in the BOM!!

@@swannschilling474 3 bearings on the 3 shafts of the 3 motors. then we see the first SPUR mounted using no extra bearings. then the other two spurs get mounted with 1 bearing each. so in total of 5 bearings are being used here instead of 6 as mentioned?.... am I right?

@@SaintAngerFTW its three bearings on the spur gears first layer, then two on the second layer and one on the third layer...it might be a little different because the uploaded printing files are having the encoders sandwiched between layers, rather than on top!

I did nor upload them yet, its still kind of an early stage design...but if I do not progress any further soon I might just upload them as they are? Thanks a lot for your comment, glad you liked it!! :)

@@swannschilling474 Please, please please upload as they are, I can figure it out, you can always label it as "version 1" and warn "work in progress" if its completion level is a concern for you, and then just post updates as you go. You made and edited a very nice assembly video 6 months ago, you printed and properly tested the design, even of there may be a few small things that could be added later this is a Lot more complete thing than 98% of the things one finds on stl host sites. I'd love to make this, I really would and would be happy to send you pictures/feedback on how it turns out if you like. I already have an fun application in mind. If there is Anything I could do to persuade you let me know. Thank you again.

Thanks a lot for your feedback!! This will be either the end effector of my robotic arm or a camera gimbal! It is actually quiet light, but might be to heavy for being build into a model rocket, but I like the idea!! Never thought of it!! 😁

Such a nice idea!! 😁

I will definetely post more on it!! So stay tuned!! 😊

Thanks!! Happy you like it!! 😊

@@swannschilling474 Subscribed for that! :)

@@Mato0092 Thanks a lot, I am making good progress!! 😊

My joint is meant to be used in a robotic application this is why I had to design it that way...but yes, you are right. Its a similar mechanism! 😊

Thanks a lot, I am just super happy that my design get such a positive response!! 😊 The tracks name is... Like That - Anno Domini Beats Super happy that you like it, its kinda hard to find good music to use!!

I have never seen something like that!! Your idea sounds great, please share your concept!! 😁

Yes exactly! You need an STLink because the board does not have USB to serial and we are using PlatformIO because it is offering native STM32 support! Still a bit to go on the firmware! Just Google SimpleFOC they are having a great Forum and are really helpfull with all stuff BLDC related!

Does that mean that you are using simple FOC right now and storm32 later? I’m doing the exact same project as you. A bldc spm!

@@constructiverealities. I guess your question is for Swann. I've used storm32 with simplefoc. It's quite hard getting 3 sensors working with it. For example spi needs a bit of desoldering if i remember correctly. I'd be interested to know if there is a particular storm32 board version that is easy to use.

@@constructiverealities thats great!! I will check an subscribe to your channel!! Maybe we can pool ideas on how to drive it! 😊

@@OwenWilliamsRobotics I did the same thing, I soldered directly to the board to expose the SPI port...but its not too complicated! There is also another board that already comes with the pin exposed! I can look it up if you are interested!

Hey, how are you planning to drive it, I would be interested in your approach! I might upload the files as soon as I find the time!

Hey I just uploaded the files, I would be very interested in how you will be driving your arm, so let me know about how your project is coming along! :) www.printables.com/model/323998-spm-3d-printed-spherical-parallel-manipulator

@@swannschilling474 wintergarten has gree licenses on his website

@@Sqwince23 thanks for the info, I will look it up!

Yes it is slightly different because it uses standard encoders, the ones in the video are custom encoders! The rest will be the same as in the video! Those motors are out of stock, I will have to make another version soon, which is using available motors! Sorry about that! Sometimes AliExpress is not the very best option!

@@swannschilling474 why is it made? What is the application?

@@KarlMiller it is made a be the wrist in my robotic arm, but could also be a camera gimbal or any other application that need a spherical joint! 😊

@@swannschilling474 it's easier for you if you answer the who, what, when, where and most importantly, why in the content of your video. If you are interested in accumulating subscribers, answer their questions before they ask (see how the Applied Science channel does this with his videos). Always assume the person viewing is an accidental viewer that would be turned into a subscriber if you can give them context for what you are trying to accomplish and reasons why you did the thing you are viewing and why you are putting it on KZfaq. I came across your video and thought the mechanism was very interesting but couldn't figure out how it would be used. Every viewer is a potential subscriber and you probably only have one chance to convert them.

@@KarlMiller Actually I never thought that this actuator will draw in so many viewers, it was mainly meant to be an assembly and instructional video...but I will make another on that goes deeper into how its assembly works and how to drive it! 😊
