How to Build Your Own Biomimetic Bionic Hand

[@rokaq5163]

I have a degree in robotics, so I feel like I have a smidge of authority when I say that your work, attention to detail and explanations are just perfect. You should feel immensely proud of what you achieved with this project, and I hope it brings you the attention and funding your talented self deserves.

[@deraid712]

Hire him so he won't rely on youtube income

[@derickayers5036]

My background is in construction, automotive repair and building, and also fabrication. My weakness is the programming process. Advice?

[@ruisuter6139]

​@@derickayers5036 do as many projects as you can... Iterate.

[@therustybiscuit6482]

As someone who does not want to build my own, I very much enjoyed the hypnotic assembly animations.

[@raidzeromatt]

As someone who does want one I enjoyed the series as well I don't know what I'll use it for.. But I know I want one

[@yxx_chris_xxy]

@@raidzeromatt I want two, a left one and a right one. I am a no-armed bandit robot.

[@trusnake733]

Will, I’ve been watching this project for 6 years, and I’m just blown away by the maturity of this hand you’re presenting here. Do you remember your hand wired boards, and telepresence glove phase? This is just something else now!!! I earnestly cannot wait to see what the community does to support this!

[@hjacobson22]

You just squeezed tons of arduous effort into a simple 15 minutes video. Bravo! This had to be a massive project!

[@AtzelTheManAnimations]

I'd Say that the wrist and thumb movements are the most accurate because most people can't usually figure out the thumb and the wrist is usually made the point of rotation of the hand instead of the bend, basically removing a lot of the functionality, The rotation comes from about a 3rd or half of the forearm. Good Job 👍

[@mtmzll]

I found your channel years ago when working on a similar hand intended as a proof of concept for a prosthetic. It was very helpful at the time to use as inspiration and allowed me to get through some difficult problems with that project. It is very nice to see your hand finally open to the world, I think you did such and amazing job and you are a very big inspiration, not only for the incredible results but for the determination you show to work on it. I hope there is much more to come.

[@idkanymore9059]

From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine.

[@yxx_chris_xxy]

Hail to the Machine God!

[@filmweaver2013]

Amazing work! Your work is a huge inspiration and omg! As an engineer and a blender user myself, I kinda understand the work that went into those blender exploded view animations, the time it takes to deal with stupid CAD to STLs, origin points, etc… and i can only imagine the shear number of revisions, failures, decisions, roadblocks… just, hands down, one of the most impressive projects by an individual creator!

[@atomatopia1]

I did a similar project with an InMoov arm! Wow is this one MUCH more complex and detailed. The sheer amount of effort you put into this project is evident and commendable. Thanks for the video and the great animations!

[@xxportalxx.]

My only immediate suggestions would be if the servos don't have enough torque to cause damage then use a script to drive them to end travel and use the pot readback to calibrate the end positions, if the servos do have enough torque to cause damage then you'd either need to run them very slowly or the better solution would be to have current sensors on the servo to identify when it hits end travel before damage occurs. I'm not sure if you're already tapping into the pot readbacks but it's a good idea to do so anyway as you can use that to automatically detect some faults, and it's a good practice to recalibrate occasionally to account for slip and wear. Im not sure if it's necessary but I've seen designs where the tendons had slack lines bridged with springs to create a bit of give in the joints for gripping delicate objects, rather than that you could also use a spring gear like assembly between the servo and the pully head (i.e. there would be a spring and hardstop between the servo and pully to allow some give if not at the end of the travel).

[@LincolnWorld]

Wow Will! KZbin is not worthy of this level of quality. Seriously, incredible work. The project itself, and the work you put into the video. I'd love to make one, but this is WAY over my head. Still very fun and inspiring to watch you do it, and I am sure elements of what I learned from it will help solve issues with my own projects by expanding my knowledge. Thank you for sharing this with us.

[@thatwannabe98]

Have you considered adding an option for patterns where you keep the hand on a constant livestream so that coders can test their written arduino code on it and see the results? That way, people who have a CS background can get involved in the project without having to go through the insane amount of construction.

[@TheInfamousDope]

Or a virtual one. They could probably simulate results on it instead of a crazy livestream rig

[@DandiIion]

Yo sick love to see someone actually support the community building their own like this.

[@mrpopcornlive3159]

I'm trying to become a bio engineer what should I know about the expectations

[@mvadu]

As someone who is following the hand, this kind of semi conclusion makes perfect sense.. May be someone with more resources can build upon to take it to next version

[@PerilousPaddy]

As someone whose hands are starting to fail this project couldn't have come at a better time, I'm really impressed with the wrist mechanism but don't like the fingers. Very inspiring, well done.

[@MrBerien]

I've started a similar (yet more simplified) project for my study and it's really inspiring and motivating to see how this amazing model is designed and functions! Thank you so much for sharing and good luck

[@wanrell]

Stuff like this always makes me want to get into robotics 😯

[@dmytrozota1904]

This is incredible work! I afraid to imagine how much additional time you put to visualize and render your work, beyond time the work took itself

[@danielc9312]

Very nice. I’ve been watching your videos for a while. This is great stuff. Thanks for sharing your hard work with us.

[@juancarlosreyes545]

I have been watching your channel for some time now. I am glad to see the progress you have made in building something truly outstanding.

[@gerryk101]

I like the way you visualized everything so that it depicts exactly how everything is put together 👍

[@calzone7961]

I've been following this project for years. I may finally be in a position to build one of these when the semester ends and I start working I will definitely get on this

[@proxyproxy3951]

I will attempt this on the holidays! Thanks for all your hard work

[@HaloWolf102]

8:17 In Blender, there are different quaternion and Euler presets you can select when rotating parts for animations. Press the N key, or bring up your side bar. In the Transform sub panel, under rotation there should be a drop down menu. This should adjust and help your Blender animations.

[@Square-Atom]

Instruction unclear, chopped off my arm and can't replace now

[@squa_81]

THANK YOU FOR SPECIFYING THE SCREWS. It will prevent some people getting screwed :)

[@alexanderblack44]

Will, it's so cool. I'm very glad that you are still working on this Holy hand!

[@johnhdn2667]

This hand has gone through a ton of useful changes and looks amazing! But dont worry, the guys in discord will do their best to make the older versions work as well. Maybe one day you can make a video of each hand and its development. Good work!

[@NakedSageAstrology]

Absolutely incredible work. Thank you for being such a gem to society. I am excited to build this and adapt it to my Centaur robot project.

[@hweeing001]

You are an angel. Thank you for uploading this video.

[@enocescalona]

makes me wonder if this could be used to revolutionize or at least advance prosthetic motorized limbs. It really looks good.

[@L3ZC]

Watching this before I could ever think of losing my hand. It look so amazing!

[@pro_suh6994]

IVE BEEN WAITING!! Thank you so much for sharing your incredible work and development witht the community! Truly a service!!

[@3xistism1.0]

congrats bro for reaching 100k subscribers I have been interested in robotics and was working on my own robotics hand, I needed some inspiration and stumbled upon your channel. I saw how talented you were and subscribed!

[@leoma3317]

Have been waiting and rooting for this Projekt for years now 🎉 i love it ❤

[@arcadealchemist]

i think the next part is creating syth muscles with Thermostatic wires and a electircally tempered electrolite gell that can be charged on and off to create conduction causing the wires to change shape form the heat. if the right metals are used and span thin so they "rotate and alter shap to create a contraction rotaition motion maybe then we will have progress and with time R&D maybe 3D printing the fibers and gell close and narrow making smaller low watage versions that could fun their own motor

[@libruhmoment6387]

do you think you'll use a finer print for the structure pieces? like the metacarpals and the knuckles?

[@SHEMZILLER]

I have a degree in mechatronics and your work is outstanding

[@SomethingSomethinNew]

Amazing material! I'm looking forward to seeing more!

[@thatwannabe98]

It’s probably the most articulated animatronic version of a human hand I’ve seen. It would be cool to test it to its limits in terms of speed and weight bearing to try to enhance it. (Edited for spelling)

[@CybrTwo]

man this would be so cool to mount onto my wheelchair. my disability makes me very short (3ft) and weak but i have semi normal arms. i can imagine using the hand tracking to open doors for myself or grab stuff thats normally out of reach or too heavy.

[@JKMV13]

This is really cool! Very impressive engineering you've done here. Someday, I'd like to make a similar project and pair it with a robotic arm. I'm working on the arm now. Approximately how much does the assembly weigh? Also, if you need some assistance with the kinematics/control of the hand, I'd love to help. I haven't done it for hands before, but I'm experienced in robot kinematics and is a subject I've been interested in for a while.

[@skoufix]

Wonderful work and thanks for sharing!

[@peterbarbieri2852]

fantastic the number mentioned means that we have to take care about the large number who are suffering andto make to try make their lives easier thanks

[@swannschilling474]

Thank you so much for all that great content!! That attention is well deserved! 😊

[@flash8050]

Hey Will ! It was amazing seeing your progress all those years and the hard work you put into your projects, videos and your job. I wanted to build this so I had to ask which wires and connector are you using for the potentiometer ?

[@rolandthsive]

The finger assembly has a little error in your video, The pulleys are alternatively arranged however in your video you have the free pulleys all on one side of the finger. which means the middle joint will never work.

[@aladinmovies]

This is amazing. I found this, in this video so much work done. Love your videos

[@MangaMan108]

Be me: binging cosplay videos KZbin: "Build bionic hands!" Me: Oh, scifi cosplay! Reality: This Mo-Fo pulling a Tony Stark, in a shed, with janky supplies.

[@arch9834]

This looks inspiring! Can you please post renders or photos of your bionic hand?

[@agelessstranger964]

Just found your videos. I love hobbyist robotics. What to build first?

[@chillchilli2671]

I can't wait till bionic hands are less complicated, customizable, and have the grip strength of a normal hand OR STRONGER!

[@TheSmokingMustache]

The complexity isn't likely to get too much better until way stronger micro servo motors are made, but the human hand and wrist are some of the most complex parts of the human body mechanically speaking. This design could likely have near to or normal human strength if the right materials are used, the pulley system he has gives the ability to greatly adjust the strength without increasing the strain on the motors so much they burn out. I'm very happy to see someone working towards building a much more usable and accurate prosthetic though =D

[@liamadamson]

I would like to ask, but don't really expect an answer. I know that this whole project is an attempt to bring this as close to a biomimetic hand and wrist as possible, and to look as close to human as mechanically possible with our current tech capabilities. What are your thoughts on making something that is less human, still biomimetic, but more alien, such as the right arm of the orokin from Warframe?

[@sebastianconde1341]

Hey! Please please PLEASEEE let me know how you did the digital clone featured at 1:53

[@eiderjosesilva6840]

Good morning! Great project, I'm from Brazil, I'm trying to develop one for sign language (Libras) but I have difficulty drawing in Solidworks, my printer is not the Bambulab, so I can't print the parts, is it possible to make the files available in STL or sldprt? Or a tip on how to separate the components and be able to print. Thank you.

[@christopherd.winnan8701]

Is there a chart of the different hand designs, similar to the humanoid ability chart maintained by Herbert Ong and Scott Walter?

[@antontrusov6951]

Hello. I think you will be able to do this: to get through the “uncanny valley” effect, I think it would be interesting to make a robotic face that would repeat a person’s physiognomy via video communication (Skype). Creating this would be a big step towards social robotization. And add AI-module will approve this

[@theocreates]

Omg that looks amazing but can you make next a arm for that hand

[@felderup]

considered using light springs to straighten the fingers?

[@rotem-whizzytherobotcreato1995]

nice, but what real world applications does it have? how can you sell it? how to make it commercial? it's just a cool robotics project

[@devnitrate]

The hand design looks really cool i might print it and not do the electronics for decoration.

[@yakirfrankoveig8094]

A little new to this chammel why do you use servo motors if you remove everything that makes them servo motors?

[@renren_does_programming]

So thats how Howard did it...

[@TrashGnome]

Thanks for all your help!

[@Nerd2Ninja]

So...after you're done building a hand, can you program it to build another hand?

[@blaqwyte9528]

Welcome back Will 1:28

[@Projekt_Nightmare]

couldn't each finger have one servo?

[@Pixe_GUM]

from the moment i understood the weakness of my flesh......

[@mangodude-nq6su]

Dude this looks sick!

[@kritikusi-666]

Halfway through, I just decided to cut my own hand, place it on the table, hook up a 220v directly to it and watch it animate. -JK obv. Great video though. But I think you are way overthinking this process. You could reduce the clunkiness and modularity of it by 50% You can print out the skeleton mechanics, use micro servos (they make heavy duty ones, depending on the weight you are working with) and then use translucent silicone to form the actual hand. Again, great video for someone learning. Good job!

[@noobdosjogos]

that thing's a beaut

[@juandiegoinfantebernal9813]

May I ask which software you used to create the assembly animation?

[@ianchan2624]

Very cool! Love ur style❤

Amazing work!!!

[@User-2737]

Hello Mr will it’s unlikely you see this but I would like to ask of you a favor, can you help teach me what you know about engineering for it is something I want to pursue as a career

[@victorgalvez927]

Will, I have an idea to add skin transduced pressure and feel sensors, if you are interested please contact me! ( i cant develop it alone)

[@kumardigvijaymishra5945]

What do you want the feel sensors to do that the pressure sensors can't do?

[@estishomeservices]

Is this something an amputee could actually wear?

[@tyleradams3490]

Thank you!

What is GitHub?

[@DeathTempler]

Built a full Inmoov arm-shoulder about a week ago to use on a Jetson Orin Nano(which took me a full week until this morning to get flashing). I'm gonna have a shelf full of AI controlled android arms soon lol. This is easily my favorite project to watch. Can't wait to see what people do with this one

[@christopherd.winnan8701]

Do JLCPCB or any of their many competitors offer a more suitable server, which requires less adaptation? Could they not offer a better design for this particular process?
