Redesigning the servos for your specialized need was brilliant.

I looked at my hand over 10 times during this video

I'm jumping on this content train. Can't wait to see more

Immensely underrated channel. Will my dude, you make some high quality content. Please keep on going!!!

I worked on a similar design back in the 90s when I was just starting High School. I was 15yrs old. I started designing prosthetic limbs because I kept having recurring dreams that I lost a limb. Some times it was my hand, some times my hole arm, sometimes my foot or leg. I still fiddle with the spect, but and focusing on feet and legs now. Thanks for the inspiration.

Love how in depth you go into the fundamantals of how the joints work. Great vids as always!

Wow!!! Such an innovative approach... I love it! Can't wait to see how this progresses!

Amazing conceptual design and engineering. I've been following your processes and thoroughly enjoy your videos!!

this is fascinating, watching you think outside the box and modify the cheap parts to your needs is insanely brilliant, keep it up 👍

You have such a bright mind. I’m consistently blown away by your progress and creativity Keep it up!!!!

Massive Shout out to You and Your Efforts My Thumb Nerves inside are Buggered

Cool stuff man. Looking forward to seeing where it goes!

You're a hero, man - you're doing a phenomenal job, keep up the good work ❤

Brilliant work rearranging the gears! I agree, these cheap servos are great for modding since it's no big deal if you break one.

Dude you are making history with your designs, keep it going. Also i am working in the same field alone with a partner, just two med students, and we have made some incredible development in artifical muscles that are realiable and are really strong. Wish in the future maybe we could work together in a project.

Very fascinating, this is a problem that I've noticed in prosthetic hands for a while, and I'm glad to see someone tackling the problem

Well done! Looks promising for sure!

Wow...Yhanks for the inspiration. Loving what you are doing !

Great work there!!! Awesome idea!

Looks amazing dude!

as someone who is in the college process to get to a mechatronics degree, this is very informative and beneficial to learn as well as to reinforce the out of the box thinking that the field needs.

I am amazed :D cant wait for further updates

really cool work man

This dude probably has the best talent I've seen in the industry.

This is super interesting, im goibg into advanced manufacturing for the 3d printing aspect and you have opened up an entire new intrest with what 3d printers can do, like makibg the lines on the printer even smaller for extreme precision or something to that effect

this is what purpose looks like, we live in a truly beautiful period of time where anyone can obtain the resources that can enable an idea to be extruded into reality.

Such a cool way to go about this!

Man, I really like your job. Awesome!!!!!!!

Rearranging the servo layout was a great idea!

Well, that was a fast like from me, amazing content as always

You are AWESOME!! Someday I will try to do it!

insane skills!

:O Exciting to see you designing a servo. It's been rattling around my head for years too, ever since trying to squeeze as many servos into a small space as possible, eventually you just think... i bet i could do this smaller by specialising the types of servos. I figure if i'm making servos to actuate pulleys anyway, why not ditch the gears and just *use the pulleys for gearing.* ;) You inevitably get into issues of the pulley/spool bend radius being so small it damages the cable, so i'm using flat ribbon instead of cable.

Loco, sos mi ídolo, me encantó la idea

nice work

Nice stuff !

Great work, interesting take on how to get 2 axis of motion in a small area. Have you considered linking the splay function mechanically so that 1 input moves all 4 open/closed?

Super cool stuff :)

This need to be heavily funded

so fun to watch

Once your hand redesign is complete and functioning, would be very cool to see this CNC machined in hard metal, 7075? Titanium? Would be a literal terminator hand.

Oh jeez. Stepping up your game I see. Great job Will! This vid literally gave me a "why didn't I think of that... derp" moment. And now we have to find a supplier of raw servo metal gears until metal 3d printers come down in price and things get realllly fancy. XD

Next level dude. Complimenting the original servos as you improve them :) Really dig how your designs are so tailored to nature. Print quality is better too. Are you moving all the circuit boards out of the new servo unit and running wires to the motors? Makes sense if you've gotta run power anyways

Okay so.... just found a few videos about creating artificial muscles ... No not those hydraulic or pneumatic ones. The ones made from supercoiled plastic filament, like fishing line. The actuation works on heating the coils. When heated they contract, also they spring on their own accord, to an extent. I'm really looking forward to what you're going to build with these servos but I thought you might want to take a look at it as an alternative for the cables you're going to use or even as an actuator for really tiny muscle groups needed in the fingers. At the very least it may be something to work as an attention grabber for the video series.

It's can make a revolution in prosthetic. I can wish you strength to design such a useful thing for humanity.

This is making me like super tired I’m going to take a nap

Idk what any of this biology stuff but robot hands are pretty cool :)

Brilliant, we get a bonus MG90S teardown video in here too (I have one I need to try and fix so this is super helpful)

Oh, I'll just make a dual-servo from scratch! Brilliant!

Awesome!

Love this channel every vid so interesting

You know, this design process is absolutely brilliant. I hope it turns out as well as you’re hoping, since this could stand to help move forward research in limb replacement (if only to actually have a decent hand design!). This could also serve in all kinds of other robotics to spur some ideas into various creative servo redesign. I do wonder however, if this could be possible to apply to the exterior of a hand through similar design. I’m thinking along the lines of Arthritic patients who might have trouble with their hands, but still have them. If this could be possible; needless to say we would need to further miniaturize the servos while still keeping equipment integrity and range of motion. It would be difficult but not impossible. This way; should joint decomposition or bone damage impair movement, we could find a means of re-aligning the hand for an almost odd form of physical therapy (if only to keep muscle degradation low). It’s only an idea, but I’d need a hand figuring out how best to make the gauntlet without being bulky, since it would need to both act as an exo-skeleton in its own right AND be as gentle as humanly possible to the person wearing it, while keeping weight low. From how you’ve got your design, it fills my head with ideas. Ideas I’d need to figure out how to make. I’m currently getting a masters; just not in engineering or robotics, although I’m considering just picking it up because I want to understand it. History is my passion, but learning broadly is a part of said passion. A curious mind to the end. At any rate, this idea is simply brilliant, and I can’t applaud the level of creativity put into the design enough.

this is fkn awesome!

You got it right, there's only so much you can do with prefab. Sometimes you gotta tear it down and rearrange it~ :D

Amazing.

Great work, Will. Hey, I am artist, and find drawing hands a real pleasure and challenge. Try drawing them in different poses, as you continue to refine your design process. I feel that the form/factor really comes through in this, and you end up with a real, sorry, feel for the reasoning of the placement of the parts.

Nice! Looking good. Love the idea of re-building cheap servos in a new arrangement. Looking forward to the next video.

that was cool

Brilliant

Bravo!

Awesome

I want to know where I can find the brass gears and to say your design is looking good. Hope it works.

Nice work! Have you looked at “Twisted string actuators”?

Man I thought I was fairly decent on Solidworks but you're ability in AutoCAD is insane. I'm not worthy! I've fallen victim to the Dunning Kruger effect and I can't get up!

This is really cool. #18

Thats a master job, have you consider using electric muscles made with twisted fishing lines?

Please make more updates on your videos❤❤🔥

Mark 2 bionic hand let’s goooo

You ever look into the artificial muscle made from fishing wire? Look it up, super easy to make, cheap and easy to drive with a voltage regulator hooked up to an arduino

Which is the book you showed at 1:17 ?

you should dive in to those solid kinematics and soft robotics

Hey, im a Biomedical Engineering student and i was wondering why would you use servos instead of other mechanisms, for example pulleys

where are you buy gear ?

I have a question. Instead of designing something based on the human anatomy, would it be possible to design something not by the aesthetic, but instead designing a superior design?

I will be glad if you provide stl files for other makers to download and 3d print them!!

Hey Will, wouldn't it be easier, less "clunky" and I guess structurally stronger to print 1 part for all those 4 servos. Those parts are not moving (or move only slightly) on a human hand anyway. I guess that would make you to be able to use less "walls" and gain more place for servo gears, thus also making the whole thing thinner. I hope my English is understandable. lol :)

Nice, thank You. I will You See on discord

cool

what about miniaturising a strain wave gear reduction system to get it even smaller? they're reversable so you'd have everything you need in a much smaller package, if you could pull it off, that is.

Is there a bionic hand that doesn’t use gear? I don’t like to use gear because they waste a lot of energy

Je te suis depuis quelques temps, et j'admire le travail que tu fais. C'est des personnes comme toi qui révolutionne le monde. Cela pourrai aidé des handicapés et aussi la robotique. Continue et surtout suite ton idée.

How long before we can make a bionic #Pear! . omg, 1t's gonna be amazing :D

What is this a 3D software?

Hi Will, amazing work with the hand. I work in a 3D printing factory in Chicago and would love to help any way I can. Shoot me a message if you would like to chat.

Вау! that's cool! I have a great desire to assemble the same device. But I'm not good at it. Can anyone share blueprints?

you should try artificial muscles on your mechanic design

are you making this because you can or are you designing for prosthetics, because I think what you're doing is probably more advanced that what's available at the moment. Excellent stuff

Bravo 👍 :)))))))))

Imagine when he finishes he puts realistic looking skin

bruh this guy is a foken big brain

You should get a pop filter on your mic. Great video tho!

Sir can you help how to design for beginners like you sir please sir

Did you ever read: An Articulated Skeletal Analogy of the Human Upper-Limb Graham Paul Whiteley?

Wow.. here i am creating blocks in solidworks and thinking i am an engineer.

If AI takes over show them this video and they can see how much work mankind has put into constructing them.

Wish i had a 3d printer

Book name pls 🔥🔥

Is this open source.

Are you related to cole cogly

Soo cool,not bead idea.
