This channel is criminally underrated. This is incredible

when i was a kid i used to study my hands to see just how they worked and what all the muscles did. this project seems like alot of fun and its cool to look at.

Wow, all of that organic mobility with only two external servos so far pulling the tendons! Really amazing work, keep it up :)

Just looking from the intro, that is one slick assembly. Imagine making the final out of cast/machined aluminum.

honestly your cad drawings just look like art, plus there functional too, well done man, well done

If i ever lose an arm/hand, im going to this dude first

I like where this is going, the fact that you are looking for a more organic hand is refreshing, I mean why reinvent the wheel? Congrats for your progress so far!

Your 3D modelling skills are legit the best I've ever seen. I can't even imagine how many planes you must have, and how long you spend to make each component.

Making a replica of a human body makes one truly realize how well engineered the human body is... Makes one appreciate for what they've been blessed....

I honestly cannot understand how this channel has as few subs as it does. Will what you're doing here it amazing and I wont lie, I kinda want to build one to have on my desk like a terminator arm. I wish more people were subbed to this.

I'm in awe of the beautiful complexity! You must have learnt so much during this project beyond the many details that you've shared.

This is fucking amazing I’m losing my shit at how calm you are about this achievement

commenting with "amazing work" "incredible content" just to make the system recommend your channel/work to more people!

I’m so out of my depth watching your videos but the are mesmerising. I genuinely can’t wait for each update. Get excited when you post. It’s so fascinating to watch

Not only do I love your videos, and think you're a genius.. but now I imagine listening to them in a big boomy god like voice imagining a god like creature doing a youtube about designing humans, and it makes them twice as good.

You deserve more patreon backers!! Someone get this man a CNC machine!

This should be the highlight of KZfaq 2020 in robotics... great work man!! Amazing!

If anyone deserves a Carbon M2 3D printer, it's this guy.

This is one of the coolest series of videos I've been keeping up with. The movement of the palm/wrist looks very natural so far. Love it!

You are a serious inspiration to my son who’s 12 and into robotics and ai. Thank you for your videos. Cheers from Vancouver!!!

there is something relaxing about watching the steps of the production process of building a hand.

That looks wonderfully elegant. Awesome.

Dang. The shapes of those linkages may be mainly to prevent collisions, but they look SICK.

Impressive design as always. Thanks for keeping us updated.

I've been building mechanical things and designing CAD for years and this still totally blows me away. This guy is actually a genius.

thats sick! Keep going dude. I've been amazed by your videos for quite a while and would love to see more.

I just amazed with every new video! Big thank you, good luck and let's hope that this concept will be very useful.

Such an inspiration and motivation for a personal project. Thank you so much for your work

outstanding as always. Really looking forward to the full prototype

this is definitely the best and most organic looking prosthetic hand i have ever seen, i wait for this series ever week

Everything looks amazing your channel is an insperation to all thank you Will Cogley.

Concerning the long screws it might help to consider bicycle spokes as a replacement. You can buy a tool to roll on the threads for very little money to make any length from normal spokes and set them in place with spoke nipples. There are spokes with straight heads, too. I've done this before and it works

Amazing work and faszinating project ! Just keep developing, this is awesome !

nice editing and voiceover. learning from you how to do awesome devlogs on robots before I actually start mine. thanks

I've been watching you since the beginning, Will. I just keep seeing things that impress me. You're quite the engineer!

Interesting! I really look forward to continuing!

Nice work!

Incredible work.

Hi man! I love your designs. It always looks so intrincated and complicated but beautiful at the same time. Thanks for sharing this prototype and well done! I´m totally inspired by this kind of projects :)

Looking great mate

Great Job Will

I love the research you've done on this

This is easily my favorite channel

This is some slick engineering!

Can't wait when artificial muscles are compact, cheap, powerful and reliable enough for such projects. I bet they would save you so much headache, and also make fingers more springy (which on pair with skin softness is quite important for grabbing stuff gently).

It’s unreal what you are doing here. Love it. If I had the money to support you I would

I thought even getting to this point would take a lot longer! Looks great!!

Awesome work!

I like to think this sort of design is what will get us to robotic prosthetics that can actually compete with flesh and bone

This is incredible ! Thank you for your work !

Any chance of a 3D modeling video or timelapse? Because I'm still trying to wrap my head around how you design complex shapes and mechanisms on CAD.. haha

Again, just an amazing job!

Love this so much

Your machines are beautiful.

Earned yourself a sub, friend! I’m more an electrical guy, but this is some really interesting successive mechanical design.

lookin good, amazing content as always, and I guess the hand is ok too.

Great video as always 🔥

Amazing work keep it up

Hi will! The build on this project is super interesting, but I am wondering if you can show more of the process of designing those amazingly complex parts that make up the 3D printed parts My background is in SolidWorks, and it seems like you use fusion 360 so I am very interested to see how you design your parts Thanks! Keep making amazing projects and videos!

This....is....aaaamazing! you are making strides in this! Oh and to see if this can get printed in metal or aluminium in the future or some kind of composite material.

Как всегда - потрясающе. Нужно собирать свой чпу, и делать рычаги из дюраля)

Cool job!

For the really long screws, you might look into using threaded standoffs to span the gap and then a short screw in each end, opposing each other. If you used a ball-head allen wrench or torx, you could even tighten it down with the wrench off-axis. A thought. Amazing work, really enjoy watching the progress on this project.

You doing good.you inspired me lots. I'm mechatronics student your video help me lots.

You're inspiring me!

Good job! Keep up the good work! And if you can, i challenge you to make a bionic hand that is so powerful and so strong, you can use it in arm wrestling competition!

Will, have you considered adding a barrel adjuster to your servo connections, to allow you to adjust the tension on each cable ? Although standard barrel adjusters may be too bulky for your narrow ptfe sleeves, you might find that a vented screw in a socket head form is just the ticket.

this channel is so underrated

That's so cool!

In the note of cnc machine, you can get an okay mini one off of amazon for a few hundred usd. I have one and while it can mill steel it is high rpm but really slow feed rate and a decent amount of coolant. On the note of cable tension, what about a mini double eye bolt to tighten the tension? Like how engineers use then to tighten cables for cross support for buildings? That or use a self tightening slip knot.

Idk why you're doing this but it's impressive

As expected and with no surprise, here‘s the request to share your design. I‘ve been trying to wrap my head around the DLR wrist design but you obviously figured it out. Can you share pleaaase?

Nice!👍

amazing!

I pushed the bell but did not see an update:( keep up the great work

Brilliant...

If you will use dynamixels or similar smart servo, it has current sensor. Current propotional to torque, so additional sensor may be not necessary.

Have you considered more compliant methods of joining everything together? Real hands aren't held together by anything as rigid as a steel bolt. Connective tissues like tendons and cartilage have a bit of compliance. Then, of course; everything is wrapped in skin. To simulate tendons, you could make attachment points that have short, strong springs attached to them, then pairs of springs can be connected with a short cable like lock wire, so it's like using lock wire to bind everything together, but there are springs at either end to give it a bit of compliance. You could also make a glove that fits over the hand and anchors to various points on the skeleton to keep things more-or-less in the right place relative to each other.

Could something along the lines of a wooden platform with spots to anchor actuation motors, with soldering style "helping hands" and other mounting positions be a possible testing platform?

Hi, your work is amazing. I'm developing a humanoid robot based on real anatomy concepts in order to achieve all human body's DOFs and Neural Network based AI. I'm developing an hand too, very similar to yours in concept, but totally different on the engineering side due to my choice of using air muscles as actuators instead of servos, in order to give an ulterior "organic look" to the robot (the hand body volumes, as well as the rest of body ones, are given by the same muscles that accomplice the motion, exactly like it would be in a real human body/hand, which would feel less or more stiffier depending on the muscles that are in traction resulting in a more realistic feel at the touch e.g. a realistic feeling handshake). The only part where servos are needed is in the eye motion mechanism where I'm using mg90s servos due to a lack of space. Given the very little space I'm working with I need to integrate the servo's gears and motor in my custom parts, in order to re-arrange them as needed and eliminate the useless stock shell volume. I was wondering if you could share the servo housing dimension, distance between the gear's axys, would be enough. I'm working with an FDM printer, and I'm really struggling to achieve the correct tolerances and dimensions. I'm waiting for my Anycubic Photon Mono SE to ship, and I'm sure that the extra precision and fidelity of resin print will help a lot, but meanwhile I don't want to stop working on my project, and I could really use an hand. :)

5:00 Maybe a parallel/delta type deal there? Do they even make em that small? 😂 Btw this robot hand project blows my mind. Nice!

Could i suggest adding an insex screw with a drilled hike thru to use in the white plastic thing on the servo to be able to tighten the wire. Like the handbreak wire on a bicycle.

hey man, congratulations, excellent job you have achieved with those designs and structures, what program do you use for 3d modeling? and how will you control the large number of actuators that will generate so many degrees of freedom?

could you design some sort of small joint lock that allows the joints to lock into position and withstand more load than the string could, for actions such as carrying a heavy bag? Some sort of clutch maybe

Node channel sounds kinda like the same guy...🔥🔥🔥💯

Incredible work! Please add 'mantis blades' to the to do list after this current design goes alpha

It's alive 😱

Great work and i learn real much from your designing. STupid Question in Bad english, would it help when you use in the Actual Movement of the wrist springs to get some weight / tork from the pulley and get so faster movement and a little more weight that the hand can handle?

best concent in youtube

You work like an animatronic artist in FX industry, the perfect combination for obtain a prosthetic hand that could to pass like a real hand, including the silicon cover... Does it the objective?

Top video

What CAD software is being used here? Really cool to see the parts all linked up and moving together like that in the software

Hi. Incredible work! Does anyone know where to buy good quality servos? I found that cheap ones from aliexpress are totally garbage :(

Someone get this guy on Tested.

1:06 you should have that part 3d printed in metal or cnc via a 3rd party . i feel it is a superior design

I was wanting to build a hand. Not biomimetic just robotic but that research led me to your videos and they are amazing! I was planning on using a VR hand tracker to try to control my hand. It would be cool if you have that a try. No point in doing all this work for biomimecry if you can't move it in a natural way.

You need to partner with a machinist with a desktop metal milling machine, preferably in your own town. Or make a milling machine yourself. There are plenty of KZfaq videos on how to make one. I'd recommend a fixed gantry epoxy granite design.

Did you see my comment about using compliant vectoring mount as a wrist? Although, looking back, it seems it might be a little large to be used on your hand.

I love your work . can you guide . how to start this

Once you're finished, you should wear glove over it in order to emulate skin. It would look awesome (if it fits, that is).
