When I first clicked the video I was blown away at first glance, this project has insane potential, please dont give up!
Thank you for sharing. Learning from other's "mistakes/failures" helps everyone improve on their first try. Very helpful.
Its great to see this design in the video and how you constructed this arm. I am more interested in the prosthetics field, but I would love to make an electronic arm myself; and I have from scratch a long time ago. I am still working on designs to this day, and you are just a great inspiration for me to keep doing this. Keep up the good work. 👍
This must have been frustrating but your progress is actually amazing! Respect for pulling through and sharing the project with all of us! Love it ^^
Good to see your ideas around having motors in the hand itself. I've often thought the hand should have some of the motors in the hand itself to make the most of the space and reduce power loss from cable transmission. Interesting project, will follow.
You are really making a change in the way we think about robotics. I thank you for that.
Amazing work so far! I'll be following your work closely from now on!
Brilliant design, truly professional grade. I could only image a fully built robot made by you.
Hey Will,
BTW great job! This is one step closer to your goal of a final product. I would like to try this and modify it on my own to maybe improve it. If I can I will come back with helpful feedback. I'm speechless at how awesome this design is! Keep up the good work!
appreciate the honesty and realistic view on everything, thinking of doing something similar for my senior year project and this was a good inspiration!
Your project was very ambitious and highly successful. Overall amazing and inspiring! Well done!
thaks for showing what most people don't see in great and successful ideas or projects, all the way you have to go trough in order to success, they just see a finish good but never thinks about how hard is the effort invested, you are the kind of people that this world needs, greetings from Mexico!!
This video has been really inspirational in my final year orthotic project, so thank you for posting it! I cite this video in my work!
Man, this is still great! I didn't get very far with my first attempt at a prosthetic arm really similar to yours. The CAD model looked pretty, but it needs a lot of work. I respect you for sharing this, especially since it wasn't working perfectly. Mine barely worked at all! I am yet to get a chance to redesign and re-try one, but I really want to. I hope by now since this was a few years ago, that you've made good progress!
Very good video, don't be bummed about it not turning out as good as you expected on the first try, first try is always a learning experience. Thankyou for sharing this, even if you consider it a failure; I for one would rank this among the best robot hand tutorials on youtube, because it demonstrates not only the craft of building but also the design process in action (love the ongoing evaluation). Until we meet again, keep building. :)
Excelent work. The result was not bad at all, you did a great job and a great video too. Thank you for sharing!
Great video and a great effort of building this arm. Congratulations and continue the good work.
Kudos to your dedication..! Great work. Keep pushing.
I appreciate your time and afford that made this video a great lesson for beginner like me. Keep up the good work!!!!!!!
I think u mean "effort" instead of "afford"
Dude! good job! i'm actually excited to make my own now! i got the palm of my hand printing right now, i'm surprised out compact your arm is. great work.
Nice video keep doing things like this!
You did an amazing job.....this is how you and others will learn. Fantastic!!!!!! Well Done!
This is amazing. Keep working on it. You hardwork will never go waste. Keep it up😃
What an amazing work , sir . I am planning forward to do something like this in my college .Thanks a lot
Excellent Video !! Seriously inspiring... Keep sharing such projects.
Glad you posted your failure here it could easily be fixed and rebuilt. Thank you for sharing!
NICE , NEVER GIVE UP , I LOVED IT
Thanks man for this video , appreciate you for the effort and "never give" up attitude
Very inspiring video - it's packed with good design ideas!
Brother don't be too hard on yourself man. I proved how clear and concise the tutorial was. I am in love with the design, but most importantly you taught me a lesson of perseverance and dedication. For that I am eternally grateful my friend👍🙏🤖👀🛠📖
Wow great job, this is awesome!
Excellent job man, seriously this is awesome, i am going to try to build open this design!
Excellent work. You learn more from your failures than success. Thanks for the video.
Well mate, all I can say is WELL DONE!
You have accomplished what I am looking to do (Hands, Arms, Legs, Feet et al). It is NOT a small feat to print and build a piece of human anatomy. You should be congratulating yourself for your tenacity alone :)
Being 'old school' (a dinosaur lol) I will do it without electronics, electric only. 18 volt cordless batteries, limit switches, ABS, simple, rough, but effective.
My hat goes off to you big fella. Keep going, you have a very bright future ahead of you should you choose to seize the opportunity...
Best of luck Will. Keep up the great work!
GREAT video exactly what I was searching for.
Thx
Great effort!! Hats off👌👏👏
very good! I enjoyed your video and the work involved to make it and the hand!
Nice work!
I like it not bad for a first attempt!
Do not be hard on yourself! Kreep up the great work, u rock!
ha, my logo looks the same as the guy before me. I was just gonna say that you really learned a tremendous amount about unexpected problems, unintended consequences methods of failure, modes of interaction. That's a huge model. You could probably develop equations for the things that go wrong based on how complex it is.
that said it's an amazing effort, and it'll be interesting if you keep the momentum on new designs.
One interesting aspect is that the fingers and thumb have and wrist have specific pivot points. They're kind of tricky to find. virtually no one gets it all correct.
So many curves and twists and angles are truly amazing. Wonderful video.
Thanks Will for this tutorial. I was looking for an arm which is cheap to build and I found the one.
Great video. I'm planning to do something similar in the future. Even though your attempt did not meet your expectations, I learnt a lot of techniques, ideas and prob saved me from a bunch of mistakes (Failure is the key to success!). Thanks mate
I am glad you found it useful, I would be interested in seeing your work when finished!
same bruh i was going to comment this word for word
Please help me im from Philippine.
@@WillDonaldson pls help me i need robotic arm my problem is no money.
keep at it some times its best to walk away for a while then come back to it with a clear mind
Keep up your good work .
I'm looking forward to.
Hi Will. Although you consider this project a partial failure I'm sure you can see that many ppl here consider it a success. For me, you have offered some unique and, I believe, valid design ideas which I will consider in my own projects. I agree 100% that the need for a functional wrist joint is important and your solution of the ball and springs is indeed inspirational. Thanks for sharing. We are ALL just working on the shoulders of giants. (and for the record, those giants had many, many failures on their way to success.) Keep the faith.
Great video, It's telling me everything I need to know. Thank you
Great work, don't give up, if you make some changes it will work...I learnt many things from your work.
Great work sir
That project was amazing keep on trying 👍👍👍👍👍👍🙂🙂🙂🙂🙂🙂😆😆😆😆😁😁😁😁😄😄😄😃😃😀😀
Thanks for the video, it is not a failure, it is just an initial step for success
It is called a prototype buddy sometimes prototypes don't work propelly ☺️
success and all good videos on youtube suck... you showed the short comings too that enlighten a careful viewer and a curious student and makes him aware of what all problems people might face while creating something. you did a fantastic job. thanks
Prototyping is all about learning as you go and modifying. Sometimes before you build.
Thanks for completing the original design and sharing so we can all learn.
I have some ideas of my own which I have concentrated on for many hours to have 2 types of clutches related to each joint in legs, hips, ankles. With combinations of Brake Clutch to LOCK each joint in place. And Drive Clutch to engage the pulley to the shaft. With free rolling pullies on each joint to get to the lower ones. I noted none of the joints move more than 45 deg + 90 deg = 135 deg. So the DRIVE mechanism for each drive shaft to the clutches also only engages for 135 degrees. Meaning Nothing but the motor turns more than that. Another drive shaft and clutch for reverse direction. Each clutch is about being moved by a lever in progression via programming to engage drive, disengage brake and so on. In effect ONE MOTOR could be used to drive all the cables to all the joints. And could spin fast to be a stabilising Gyro with a gear box for torque for the 135 deg movements. It a very interesting puzzle to consider.
Tesla was able to design prototypes in his mind and modifying them before building. Though of course such things take practice to build the mind skills.
I like the idea that wrist is interesting. From personal experience power of the grip is not from the hand but from the forearm. 4^th & 5^th metacarpals (full Boxer's fracture) and a growing list... Think open along with wrist up/and so below to close. On the wrist pieces make it so the small side goes to the ball. Maybe scrap the springs for curved telescoping about where Tib./Fib. are on top and bottom respectively. To accommodate for your lines (tendons).
Really cool knowledge. Physical therapy along with the correct workout. After 9 years. Start to feel like Doctor Strange. Hope this was helpful.
Damn that's wicked cool
Omg its amazing i want to be your student from Brazil! Thank you teacher!
Hey just a thought, you don’t need to use a servo for each finger, you could have a single servo control multiple or all fingers. Depends on how much force you’d expect though.
great video, i will start as well projects like this
great work! keep going with this, it is awesome. i'm working a similar project. good luck
I’m so proud of you. You have no idea...

Got em 👌
very nice thank you for uploading this video helps alot :)
As a disabled person with an incomplete right hand. I think the focus should be lower forearm or just above the wrist prosthetics such as what u did. Creating a circle or half rounded flexi mould for the wrist on your design and taking the black outta cabling and internalising it.
All in though great first attempt
great project.......more!!
Good job
I feel like you should revisit this so you can prove to yourself and fix all the flaws in your design/electronics. This was amazing by the way. But it can be excellent if you're willing to spend more time on it and fail thousands of times over and over until you solve each flaw in your robotic hand.
kEEP IT UP, it looks amazing..
Thank you
Great video.
Its great man. I really appreciate your hard work for making this thing happen. Actually I'm also planning to build an affordable prosthetic for the amputees under a major research project in India. I hope to take your valuable advice some day.
Excellent work. To me the question "is it all worth it", never factors. No matter what challenges or difficulty, my end goal is to make a more functional prosthetic which can benefit people. I give up,I let them down. So it's just another challenge to me if I can't solve something
GOOD WORK
well done ,keep up :)
Servos for the thumb in the palm, others in forearm? Great video, more informative than edited triumphs.
thank you
Great video!!!!!
superb bro
I dont consider it failed, success is a process, now you know the issue, you can address it. nice video. the community thanks you.
As a robot i aprove your creation
Nice effort
amazing. i like it. thanks i will learn from this.
Hi !! Thanks for this excellent video ! I can understand how difficult it must have been ! I want to build one too! If we compare to the anatomy of the forearm, all strength to flexing the fingers comes from muscles in forearm and those for the finer movements are in the hand. So if we place the motors accordingly , would be great ! Also the circuitry could be outside the forearm .. like having a separate brain for the arm!!! But all this is just theory as of now
Tanks very much Master..
Good..I'm is Ciamis West Java Indonesia.
Muy buen trabajo, me ha encantado
All the best
How familiar those feelings...
This is a great projected you must have lots of patients I have a muscle wasting condition which is starting to effect my hands more on my left hand then the right hand but it it will get progressively worse. I will hope to fined a glove like this to help.
Thanks for the support! Unfortunately this is not a medical device, merely an experiment. If you are interested there are other open source robotic hand projects online that may be more functional in a real life situation
Good Job!!!!!!!
this shit was dope!
This design like great Although I would Def change a couple things myself, I'm building a andros now a year and I'm currently doing toes and fingers as well as orbital socket and it is a challenge, keep up the good work my man the only a few of us who are no bodies but can take on projects like this.
If I may spend more time in fusion 360 with this model and play around with your caliper once you get this done printer model orientation will be the best next thing to play with, in other words don't keep positioning your model the same way on the printer and STOP using support only use raft
Nice video
Great!!!
Thank you for posting this video Will. Been looking for something like this to try with the FormBox. Have you ever tried using vacuum formed parts for the hands?
I've never used a vacuum forming machine, in the future I may experiment with one. It should be possible to make the required geometries, however my concern is that the plastic walls may not be thick enough to maintain structure integrity, also inserting axles may be tricky in vacuum formed parts. But as I say, I've never actually tried and could be wrong. It may be possible to make a hybrid hand of both 3D printed parts and vacuum formed parts
That's a great idea. A hybrid could work beautifully.
If i had a 3d printer i would have definitely tried this
I had this in my mind for las t 6 months
Is amazing
you deserve to be subscribed bro you don't afraid to post your mistake on TH-cam great
btw I really like the design of the 4 springs at the wrist
I want to help poor people to provide them cheap prosthetic or free
for their living and I'm now working on this project how to make a arm which works like normal the servos are really very slow I want something like our muscles hope that we can build this
very well job ....
could you tell me how can i make some edits on Fusion 360 file like open it in SolidWorks and make some edits ??
I'm always looking for ideas for robotic hands. Just meant as constructive comments: I would personally drop the background music. And perhaps explain things in more detail. Just my thoughts for whatever they might be worth.
Fix the weak thumb by supporting the rotation with a metal tube epoxied into the thumb base and ball bearings in the palm. That way the motor shaft doesn't have to resist bending stress.
Metal gear servos!
Eliminate the servos' housings and design the plastic parts to directly hold the motors and gears. It'll be stronger and less bulky.
Those are good ideas. I agree, the shaft of the servo which the thumb is currently attached to is too small and weak. I also hadn't considered directly putting the motors and gears in the hand without the plastic cases, that should be a fair easy modification to save space
great 👌
