Absolutely underrated channel. Very nice work.

[@Skyentific]

Thank you!

[@nexgen6305]

Thanks you dude my creativity Is More fly when i watching your videos

[@SamuelRobotics]

You’re the motivation to everything i do 😍

[@Skyentific]

Thank you a lot! This kind of comments motivate me! :)

[@SamuelRobotics]

Skyentific your videos motivate me!

[@geripapaable]

Skyentific... the tipical channel which when pop out a new video i click on the like button before i watch it, because i already know it will be awesome. Man you are a great!

[@MrEngineer_]

thanks to your passion and knowledge of mechanical systems ,electronics and many other technologies...u gained a subscriber ,cheers!

[@veremenko]

Субтайталс фо зыс видео шуд би ин сырылик. But honestly awesome job, love watching your detailed review of the mechanisms you build.

[@jackgeorge6288]

Hey, I’m in my first year of a mechatronics (robotics) engineering degree, channels like yours and James Bruton get me super excited about building this kinda of stuff in the future, I’ve already got plans of what I want to do and learn over the holidays in between each semester and I can’t wait. Thanks for uploading stuff like this it keeps me looking forward

[@sofuckingannoying]

Man, I wish arduinos and 3d printers existed when I was in college. We are now in the golden age of hobby engineering.

[@yannmegard25]

thanks man, you are slowly solving all questions. But that is concrete building up. I'll keep tuned for shure.

[@laljiahir5193]

Future is bright

[@ransombot]

Don't comment on all the things I watch but I wanted to say thanks for your videos, you inspired me to take on the challenges of designing some things I'd never have tried otherwise. Wish I could afford the things your using but I learn a lot & google a few things better because you give me some nomenclature I'd never know otherwise. Your a huge help thank you.

[@georgegal6756]

Awesome work! Congratulations !!

[@mmawad100]

A genius mechanical designer keep it up thanks for showing us that art.

[@unionse7en]

i commend and respect you MORE for showing your design failures, people learn much more that way! #keepsitreal

[@tobynmanthorpe]

Satisfying movement!

[@stambo1983]

Great work as usual!

[@Skyentific]

Thank you!

[@ElectronDust]

Very nice and clean design. I like it very much. Hope you'll make the movements smoother once you're getting into hardcore-programming-mode.

[@FilterYT]

I like the orange one with grey sides,

[@AdityaPrakash-kt3rf]

Even though this is an alternative shoulder, the sheer beauty of this build is amazing! Hope you complete this robot!

[@vakhtangtsikolia9317]

I look forward to when you take up the 3 laws of robotics

[@3dmechanicaldesign]

Thank you sir .👍👍👍

[@robertgray7961]

Nice work! Thanks for sharing your pile of reject parts. That makes me feel a little better about myself. ;)

[@diegomedina2929]

You make amazing videos and amazing robots!

[@RubixB0y]

Great job on the second robot shoulder! It's helpful to see a comparison on second way the arm could be implemented with more safety in mind and a different method of controlling. This new arm seems very powerful, but in my unqualified opinion, I like the idea of having the belts on the low-torque end of the planatary gearbox. So I'm happy that you're continuing on with the o-drive version. I know it's a safety hazard, but seeing the motors, belts, and gears spinning is so beautiful!

[@Alex-xh1zi]

That pile of old prints shows how many hundreds of hours you've poured into this. Great work!

[@TheTotalGeek]

I love the way your design is so clean. Brilliant.

[@enott]

Ты абсолютный идол!💪💪💪

[@alexeymaslov3865]

Ардуино - навсегда. Спасибо за видео.

[@teslastellar]

Well done 👍

[@paulxander5970]

Dude, you rock.

[@brian8687]

I aspire to have your abilities at creating such stuff someday; You motivate me.Thanks for that

[@deepakforyou]

It's a great channel.. 👏👏👏

[@TheTugge]

You have designed something remarkable here. I'm quite inspired from your work and maybe i will build something like this some day. Great stuff and I really enjoy to watch you videos!

[@klausnielsen1537]

6:02 I can tell that you are happy with the progress. I think it is well deserved, you move forward at great speed. Wonderful!

[@localhawk1]

I like the size of the new parts!

[@mohamedelsheraiy]

Great as usual 👍

[@marcalcivill8326]

Amazing work, you inspire me with every video, thanks!!

[@Skyentific]

Thank you for such kind comment. Really appreciate this.

Your effort is amazing. I love learning from your videos!

[@HassanOmariprofile]

as always, very impressive and amazing design, thanks for sharing 👍👍👍👍👍

[@QuanrumPresence]

This is really amazing, an inspiration to make robots. THanks for posting, I hope you get a lot of subscribers

[@derasor]

Your work is so slick! beautiful.

[@pixlfactory]

Мааааn, you are crazy!!! You know that right? Keep up the good work!!!!!!

[@alcryton6515]

Great video

[@zeuss194]

This guy is the one man army of the engineering departement

[@GregBakker]

I'm loving this series of videos. You make the experimentation look effortless; I know it's not!

[@tatoaraoz]

Amazing information you spread!!

[@rvjenya]

Thank you so much for your amazing videos. You are making a clear explanation in robotic. 👍🌟

[@NurdRage777]

You need wider (+Y axis) grears and belts to get higher torque spec :) Nice video, thanks for sharing the knowledge.

[@Chris-bg8mk]

Need to close with a heavy metal track and the three of you nodding to the beat! You make beautiful robots sir! You could make a beautiful tracking mount for telescopes and other aiming projects!

[@larrykrepp7428]

Splendid

[@alfiolocatelli5093]

What an amazing work! I prefer the quasi-direct configuration, seems like more industrial, belts are not exposed and dust dont engage motors! (I hope you change idea with the configuration to go ahead 😂) .

[@vladimirtatarchevskiy5886]

It's awesome!

[@3rdaxis649]

I like the 3rdaxis;)

[@Hesponge]

You should maybe print a wrench with 3 pins going in the screw holes to tighten the idlers, judging from the tension needed in the pulleys.

[@DanTheHero00]

Thank you for everything!

[@jbrownson]

Thanks for sharing your work

[@juanfranciscochiriboga2884]

Hi ! I love your videos. You had inspired me to make my first robotic arm. Great video as always

[@badrmoutalib7368]

I'm learning so much from this. Thank you sir .

[@KhalilEstell]

Awesome work! Was looking at the same actuator and found your channel. Great content!

[@АлександрАлександр-б3г2б]

Восхитительно!

[@MechaMiguelWorkshop]

I love your job man, awesome content !!!!!

[@Flare1107]

I have a design suggestion you may want to consider. If you'd like to consolidate the mass to the base. You could use the same bevel gear design, with a bit different power transfer method

[@YetiFell]

Instead of adding a rotation limiter, maybe you should consider slip rings. Power over slip rings is easy, data/CANbus is not as trivial but still can be done. Freely rotating joints enable much better kinematic motion planning (best for base and flange)

[@WhiskyLima]

Awesome! Look forward to the next video dude!

[@BebenX]

So excited! Love your work!

[@besthealthyyou]

Love your content, such passion for robotics! I'm currently experimenting with a planetary harmonic drive actuator 3d print design, 100:1 ratio with small profile.

[@viniciusnoyoutube]

Nice!

[@nosferatuohnezahn6630]

THIS IS HUGE!!!! How much hours do you spend to Plan and build stuff like this ?

[@Skyentific]

A lot. Really a lot. Here I spend more than a month in total. :)

[@OtherDalfite]

Building circuits can take weeks, not even to mention planning the mechanisms and the housing. To come up with a whole project like this in only a month is something only a pro could hope to accomplish. Great job Skyentific

[@yf6595]

@@Skyentific salute

[@icebluscorpion]

this arms would be good for a spider build or an improved version of spot XD

[@TheAmerTV]

Perfect design I do like it so much. I do have one concern is having all the load on the bevel gear will decrease the max load that can be handled to the teeth max shear load. however if its well built it might be enough.

[@rizalardiansyah4486]

Indeed, but sometimes its better to break some 3D printed gear rather than some expensive servo motor due to overloads.

[@dinoscheidt]

When you have time, you should do a video about your 3d printer and printing workflow. I am constantly amazed by the quality of your 3d printed parts - and as someone who owns a 3D printer too - its not straight forward to get that level of consistency.

[@RoboticalHeart]

Wonderful work. This is one of the best DIY Robots related channel in KZbin. I see you're using Prusa i3 MK3S 3D printer. Do you recommend going for Ender 3 V2 as a cheaper alternative ?

[@souadsouad3697]

Nice

[@heinerle07]

Exactly! :)

[@zhiyanghe9727]

Amazing video! What 3d printer do you use for printing the parts?

[@juancarlos-bq6ew]

A lot hard work 👏

[@Goodwill345]

This is a lot of work you have done, you are such an inspiration for the entire robot community. I wish you all the success and I am hoping to buy your robot arm for Thanks Giving. What will be the payload, if you can do 1.5 kgs at the end effector arm length then sir you have winner. Then comes cost, for most of us it has to be reasonable. Let us say all the parts+labor+design charges+premium+testing cost+packaging cost+ shipping? May be if you decide to mill aluminium for some parts then that cost. Overall we are ready to pay for all that. If you open source or license your design then more people will jump in to help the community to keep the cost down for the end customers. You are the boss, hopefully everything is in the works. I just want to say 5000$ will be too expensive. 3000 for DIY would be a Gods Gift to the world. But you are the boss we don't know how difficult it is. I think it is difficult otherwise everybody would have done it. I prefer the bigger quasi direct arm that you have. It is a little bit big but for that load it may be acceptable. I wish you good luck, your success is our success Thank You

[@olegpetroff6186]

великолепно!!!

[@mindprobe3587]

Present sir

[@EngineeringSpareTime]

Really neat design! Always enjoyable to watch. I like the idea of using a differential transmission. How do you plan to accommodate for the split of torque in axis one and two in accordance to there relative speed/ acceleration in your motion control? Have you thought about preloading the bevel gears with an additional gear to reduce backlash - more complex design, but might be worth it!? And what about a master an slave design to power an axis? Using two smaller motors to drive one axis: using both for acceleration and then both with an offset in torque to “clamp“ the gears (++lower backlash, - higher cost, - more difficult to design the control algo, -less power density)

[@tommasorizzi6932]

Fantastic video!! Can you make more video about the program of the robot, in particulary about inverse kinematics??

[@philiqp3]

Since I saw your videos i wonder what I coul d do with a robot arm, I can't have just for fun... I'll find for it a thing to do.

[@Alex-xh1zi]

I want to see an arm wrestle between these two versions!

[@CharlesFormanWonderUnit]

You are the best!

[@figbig1338]

Молодец земляк. Так держать удачи.! Для куки есть разработки?

[@diegomoreno7704]

You're awesome

[@dantesk1836]

I'm putting one or several comments. ;)

[@gerlofdeboer4552]

Very Inspiring ! And may I make a suggestion to improve the lifetime of the gears drastically ? For daily operation the travel of the output axis could be limited to 360 degrees or so. But if you nevertheless could design the cable management in such a way that you could allow the output axis to rotate to say 3 times 360 clockwise and 3 times anticlockwise, then you could create 6 different 'modes' for the shoulder. And you should than modify your gear set in such a way, that in each mode you have a new 'fresh' set of teeth meshing with each other. Was it not a general rule in gearbox design, one gearwheel with uneven number of teeth should mesh with a gearwheel with even number of teeth. In that way, wear is evenly distributed over all the teeth.

[@yosso770]

Hi Skyentific, Thank you for all the great information, love your work! in a previous video about robot arms you talked about how the best movement would be to move like a human, now I understand you mainly talk about industrial type robots arms but I was wondering if you can touch on the topic of artificial muscles like HASEL actuators and using them to create lifelike robots I will be attempting to make mini silicon muscles like they show in their paper in the near future, Love your work great stuff!!

[@sfahadrizvi]

As a new subscriber I am sorry I missed your channel for such a long time. You have some really informative and well made videos. What 3d printers do you have and CNC machines. Also it is also very interesting to know how long does the prints took and settings. Also a small time lapse on the top corners of the prints might be interesting to people who like time lapses. Great work :)

[@elcrackent13]

Hi SKYENTIFIC, i have a question for you. What should be the route to learn robotic online? Also I have a suggestion, in this channel you have a community that would be very interested be teached from a Master like you. Regards

[@rc-micro]

Looking this great video I’ve got an idea, you could use the top part of the older shoulder as an elbow and you already have an 5dof robotic arm !
