Хм, спасибо за идею о внутреннем контуре в виде повтора циклоидального диска, я почему-то все делал просто круглой полкой, из-за чего нужно было части корпуса собирать вместе с дисками, и потом диск было сложно извлечь.
Sir, why do you mark the cyclo part? I rotated the top cyclo by 180 deg.but the output holes are not lining up like yours. What have you aligned the dots to? Thanks.
Hi Petar, I am currently building your robot but I was wondering how much payload it will be able to handle. Can you make any estimate on that? Thanks for the nice build! Cheers
@@source-robotics Great, thanks for the fast response! Indeed I have a pile more questions but most of them I will figure out on the way I am sure :) One thing I was wondering though is how I would control the six motors as it seems on the documentation websites of your robot, that you stopped selling the pcbs that you had designed for it. I thought of resorting to this option called "GRBLDuino MegaShield" ( www.tindie.com/products/eccentricwkshp/grblduino-mega-shield-grbl-11-arduino-cnc-shield/ ). I would love to hear your thoughts on that or alternatives to it. In your "CM6 Cobot - Motor jog demo" I saw some other driver(?) assembly in the background, so maybe you use something else these days? Cheers!
@@source-robotics Also all the circular print patterns give me a hard to to find a good way to print with nice adhesion. There just is too many small circles that dont stick. Maybe you have a pro tip for that?
@@source-robotics I work with a ender 3 pro. I also use PETG as advised by your website but I stick to 0.2 layer height for everything. You mention to vary between 0.35 and 0.2 I think but I didnt know when to use what, so I thought 0.2 should be good. I can barely believe that you didnt use supports on the big parts. I am printing the joint 3 cover right now and I didnt dare to just rely on bridging. Especially because I think PETG is inclined to warp on the larger parts when using a lot of aggressive cooling. Maybe I am wrong on that though, dont have that much experience in printing yet.
What i don't understand is why you don't put a pinion from the eccentric and make the pinion turn once using the.cyclodial to make a 1 to 1 ratio increase torque ruclips.net/video/9l9QMz67J0c/видео.html You put the pinion where the cyclodial moves one tooth and make the pinion turn once making the pinion have more torque Why wouldn't you do that
Here's what i think I think if you make a 6 to 1 And put 6 off centers so there are 6 points that move 6 rings one tooth and you put one ring around the 6 rings so the one ring does a full turn when the motor turns once that you will make a 1 to 1 ratio increase torque I believe that is what God intended a cyclodial to be used for Because anyone can make 12 teeth move 11 and the 11 goes up by one tooth or 100 moving 99 But 6 off centers moving a outer ring once when the motor moves once cannot be done any other way Please try what i suggest

As an electrical engineer, designing gear boxes terrifies me haha.. Awesome work
www.otvinta.com/cycloid.html
You will cry?
Excellent Work. Greetings from Venezuela.
Nice work, I hope you have time to create additional assembly videos.
Bro can you plz tell the backlash , and can u do show some torque test video. ...? Although bro. Great work👍🏽😁
Bravo, svaka čast!
Nice video, I'm glad you share this one. Just wanted informations about this component for knowledge, I'm not engineer.
How big is the reduction of this box?
Nice work Petar. Do you have an Excel Sheet with the formulas about how to design the cycloidal reducer? Thx

Hello! Long time fan. What is the estimated total cost of your robot?
Nice! what is the backlash ?
Amazing work. One question though, does the reduction, 12:1 or 10:1 affect the output torque ?
@@source-robotics okay, thank you
Do you think using a skate bearing (8mm id, 22 od) would work? I have a lot of those.
Is there any guideline or books that can help me with these gearboxes design?

1 kg at low speeds. If you have any more questions about build feel free to ask!

What printer do you have? I printed all parts with PETG and 0.35mm layers. Also no support, you can use bridging for most of the stuff.

GD&T my friend
Where can I buy it?
You cant. The whole robot made with these actuators is open source so you can build your own.
No "money" shot of it working.
Well my expectation is to see how it works...

Why wouldn't you do that
Are you how to mechatronics?
I wish! :P
Here's what i think
I think if you make a 6 to 1
And put 6 off centers so there are 6 points that move 6 rings one tooth and you put one ring around the 6 rings so the one ring does a full turn when the motor turns once that you will make a 1 to 1 ratio increase torque
I believe that is what God intended a cyclodial to be used for
Because anyone can make 12 teeth move 11 and the 11 goes up by one tooth or 100 moving 99
But 6 off centers moving a outer ring once when the motor moves once cannot be done any other way
Please try what i suggest
