I feel like the biggest thing our friend Ian is proving here is that maybe we all got a bit carried away with trying to make "advanced" prosthetics when we could've been making much cheaper, simpler alternatives that also work much better at the same time. It blows my mind how barely functional some of these medically marketed prosthetics can be considering how outrageous the pricing can be at the same time, when Ian has been making way more functional prosthetics in his garage for these past few years for what I assume is considerably less money.
@@MosiahWhite Electronics are awesome, and can achieve much more than mechanics alone can when applied properly - but where mechanical solutions work, they work damn well
@@patrickhector Something funny I noticed (since I'm a programmer) while working on car projects with my mechanic friend: as a guy who works with mechanical solutions, he praises the reliability of software over mechanics. Yet, I always say as a programmer, "No way! Mechanics are way more reliable than software!" Hahaha. I guess it depends on your perspective ;-) But I'd 100% take Ian's solution here over some of the slow, more digitally based prosthetics I've seen online.
Honestly if i lost a hand right now I wouldn't use electronics I'd use a rope and pulley system or some kind of soft robotics. Especially because I'm training to be a welder and I don't think electronics would be happy with that lol.
@@MosiahWhite I figure for prosthetics mechanical solutions are more likely to become intuitive, just because they're inherently physically responsive and physical responsiveness is really important for muscle memory
In spite of all the CGI effects that we get nowadays seeing a mechanical device moving with the fluidity and intend of an actual hand absolutely amazes me. This prosthetic looks like something decades in the future and I am so happy it is poised to become an actual product.
@@seemi8053 Yup. Expensive, slow, and zero grip strength. Servo motors are not suitable for functional prosthetics. You need tendons and muscles, whether they be flesh or metal.
Using the backside of the fingers for lifting is genius! And those ceramic coatings are going to look super stylish! Especially if the chips showed in the video are the colors you're going to test, love the dark grey and orange together.
They are, orange for the drive components, distal link, spring, chain, driver, black on the distal, prox 2, winder top, and sockets, Grey on everything else.
You are extremely dedicated and innovative, and I can't wait to see how your work affects the world of prosthetics! I've been watching your videos for about a year now and in every video I'm just amazed by the engineering involved!
The one for Bryan, yes. It's getting close, but it's proving to be a completely different animal than the mechanism that I use on my partial hand. Also, where Bryan has been so long without the use of his finger, it's more of a zhu zhu for him than anything else.
Stumbled across one of your earlier iterations a while back and seeing the project pop into my feed every once in awhile always makes my day The hand looks amazing and you give a good example to anyone interested in mechanical engineering and design
Hey Ian, been lurking for a bit, but just wanted to say, the engineering on this and the continued improvements are beautiful, keep up the awesome work. Hope these make it to production and into the hands of people who can make use of them, I'm still awe struck with the level of utility and range of motion these are capable of, truly a functioning work of art.
I’ve always loved your complex but unpowered prosthetics as opposed to ones with motors like the bebionic because I can see yours just being so much more actually usable and feeling like a part of the wearer (with today’s prosthetic )
A great update video, and excellent to hear you're stepping back just a hair so that these updates aren't "hey guys, it's Tuesday, I sanded some of the pieces to fit tolerance and made sure the screws fit properly." Aside from that, I'm not very knowledgable on the sales side of things, but making everything as simple as possible sounds like the right idea to me.
this is absolutely crazy man, I've been really interested in your stuff for a while, you make me want to get into prosthetics and I cant wait to see what you come up with in the coming years.
This is the most steampunk thing I have ever seen. I love the design so much! Respect to you, Ian! One idea: Have you ever thought about going with a non five finger design? Maybe 5 fingers are not ideal? You could literally build the perfect hand from scratch and laugh at us 5 finger peasants. 😂
This is probably a case of "the correct number of fingers is the number you're used to" ngl, though maybe dropping the number to 3+thumb wouldn't be the worst idea for the sake of simplicity - as amazing as this hand is, it certainly doesn't take as full advantage of 4 fingers as a fully articulate bio hand does
That's not a bad idea, especially for people who didn't grow up with a standard hand. Without the ability to individually move fingers, especially sideways, only 3 or 4 fingers may be easier to do. Although, I would guess other than reducing the number of parts having bigger sturdier fingers would only be useful to people who would regularly be abusing the hand alot. Like a blacksmith or something. Hell, for a blacksmith having a metal hand may be better than bio hands! lol
I definitely appreciate an update that is meaningful to your progress. I enjoy your presentation style so I do selfishly wish you posted more often. Thanks for your effort!
cerakote is also GOATed in the EDC community. enviable bolt-action EDC pens, and now prostheses? i’ll let people who understand your described engineering ingenuity give you proper kudos, but what an a awesome update to an awesome project.
I haven't checked in on this project in a minute but I'd say this is definitely the state of the art of prostethetics. Since most "cutting edge" stuff uses materials that no one can mass produce like with aluminum and steel. Not to mention your prowess and passion for it.
You're an inspiration to aspiring engineers such as myself. Perhaps the coolest project anyone's ever worked on. I always appreciate your elucidation of the engineering and design process. In a platform full of channels that treat science and engineering like some magical thing that just happens, channels like yours and @engineerguy are paragons of the true engineering process and the rigors of science.
Hello sir new subscriber here from philippines.. my First born son got the same hand like you sir on his left. im interested of your works.. hopefully i can also make it for him.. thanks God he used you.
I love your dedication to this project. I have no need for it, but I grew up around WW2 and Korean War veterans who were happy to have the very limited claw-type prosthetic. One of my Grandfather's friends had both hands blown off in combat (he always said that it was a bank-robbery accident to avoid having to talk about what really happened). I wonder if anodizing would be an improvement to long-term durability. Having the parts made undersized to allow for the treatment (and possibly eliminating the need to file) could allow for a kit that only needs to be anodized at home to the color preference of the end-user.
could you build a mechanical second set of hands that attach under the forearms and biceps? have them pointed inwards and mechanically locking. could make carrying things easier for people who just have weakened grip strength. or even just help workers carry more items in one trip
Ian, did you ever do a video explaining your idea of a product? I mean, each amputee will have their residual limbs and whatever muscles and tendons are there, so the actuation range and the number of degrees of freedom will vary. Are you going to redesign each prosthetic for the specific use case? Not that this would be bad: to have a device that restores a lot of functions, behaves smoothly, has haptic feedback, no batteries, and a is gorgeous is mindblowing.. but not cheap
Man, for April fools you should do a parody of the Rockwell Retro Encabulator video but with your device. The way you're able to toss around terms for the bits and pieces of your device would suit it so well.
Brilliant ideas. One of your video inspired me to build my own design of prosthetic hand. I have just started to build a concept model. Hope we can share our experiences one day.
It's really cool to see you incorporating more features and techniques that augment the abilities of the human hand rather than just replicating biological features. Holding something heavy on the back of fingernails seems uncomfortable, but if you're designing those parts it makes sense to continue to make them good at grabbing on both the "pad" and "nail" side of the distal tips! I know you've gotten all sorts of "go go gadget" "add a wire stripper pinky!" (and that would be cool), but it's even more interesting to see what sort of grip positions might be useful even if they would be biologically uncomfortable or impossible
I think you'd have a lot of success partnering with some of the different Veterans charity groups who do work with amputee veterans. Great work as always!
I like the alternative solution to locking under load. I'm curious to hear after you've worn the new design for a bit if you run into any issues with larger objects being to bulky to easily get on the knuckles vs hooking the whole fingers around them.
It's mostly geared for roundish shapes +/- 1" in diameter. Since the weight still gets suspended about the back of the thumb and wrist, the weight is also a factor as to how well it works.
have you considerd that some individuals might want to hange using the prosthiesis, i do not think thhat this lock under lode will work for hanging from bars 😄. grate work overall.
This is fantastic. Would it be available in different configurations for different hand impairments? I wouldn't imagine a lot of people have your exact hand.
My understanding is that the moving hand parts would attach to custom molded parts that fit over whatever is left of your limb. I'd guess it should work for anyone who still has part of their hand past the wrist so that they can make the left/right and up/down motions he uses.
Will there be room in the future to possibly say for example have the tips of the fingers be swapped out with utilities? Such as ceramic safety blade, wedge for prying etc
The fingertips already have that feature. I have ones made from silplat 40, tpu with a concave on the back for general purposes, concave on the back that fits machine handles, and ones that are essentially claws. That was one of the advents that started with this series of devices.
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. Your kind cling to your flesh, as if it will not decay and fail you. One day the crude biomass that you call a temple will wither, and you will beg my kind to save you. But I am already saved, for the Machine is immortal… ...even in death I serve the Omnissiah.
Using chain, This design is very cool !! And be able to increase the strength to use chain, isn't it. I want to be able to do mechanical design like this hand. Am I able to tell you that I want to say ?
If aluminum does not work, 3D printed titanium is pretty darn good. I have had a few parts made in the material and it is as good as machined grade 5 Ti.
I looked at having the proximal 1's printed in titanium since they're under the greatest amount of load, and i may need to do so if i start to see excess wear or failure. But to have everything printed in titanium exceeds the price point that I'm trying to hit. It's super cool, but it's super pricey at the same time.
How much would the inclusion of the thumb change the overall design? Also, would this design be functional for each individual finger? Not sure if I worded the questions correctly, but I hope to receive some answers.
Amazing update. Your production quality has gone up since the last time I saw your hand, too. Cerakote is good stuff, but don't forget about Durakote, either! IDK if the industry has moved on or perfected the affordability od Cerakote, but last I read about the stuff (roughly 4 years ago) Durakote did most of what Cerakote could, but was simpler, didn't come in as many colors, and thus, was cheaper. A point of criticism, though: Your video is far too quiet. Looking up the metadata for this with right click>stats for nerds, it's over 18db quieter than baseline. TH-cam only compensates for videos that are too loud compared to baseline, but YOUR video (at least this one) is about 3x quieter than it should be, which is a pain when there's only so much someone can crank the volume up on their end.
Curious if I've thought about using zinc parts since they self lubricate or would they not be either cost effective or strong enough for ur application
Wow, your mechanical ability is awesome. You should be funded already. But our society places importance on sports players as opposed to people doing real things.
I know you had trouble with marketing the prosthetic as a medical device, but is it possible to instead market the kits as novelty, hobby, prop, or toy products instead?
What kind of coating thickness does Cerakote need? I.e., does that require a decrement in part thickness anticipating the coating, and potentially a doubling in part versions for coated and noncoated?
There was a meeting about that topic. The thickness varies by applicator. But plan for 0.0035"/side. So where the p1 and p2 cross (4 surfaces) , 0.020" will net you 0.0025" ×2 of clearance for the parts to pass each other and not drag. Rn I'm thinking that it's probably going to be 1 maybe 2 applicators that get the project, where you would send your fitted parts to them with colors. We'd have an expected price. And it would just be a line item expense. It's still super early, it might not be as finicky as I'm anticipating, but better to be on the lookout for this kind of issue to arise than not.
Using simple physics to achieve carrying heavier loads is something I've never seen elsewhere with motorized prosthetics.
