Thanks! A new video is coming soon, I'll discuss more about assembly. I've found ir diffcult to film some of the fine details of the assembly because many small things go wrong and it takes a lot longer than anticipated
Awesome! I made an inmoov arm myself. I was wondering if you think the extra degrees of freedom for the thumb will be sufficient for an amputee, or should the fingers ultimately also have an extra degree of freedom?
That's great, how did it turn out for you? Extra degrees of freedom in the fingers is ideal but I believe the thumb is more important - it allows for better opposability to manipulate objects between the thumb and fingers. I could later on have motors in the forearm driving tendons for added degrees of freedom in the fingers
Mech Designs & SolidWorks Tutorials Pretty good! Still having some twitching issues, probably power supply related. Thought a big capacitor and small capacitor would handle peak current draw and filter out noise on the line.. I’m equipping it with a camera, and training a model to have it play rock paper scissors with humans at the moment. I had some other ideas with grasping of objects, but it doesn’t quite cut those tasks.
it's a nice design but the heel of the hand is actually thicker than the wrist. So you could put the thumb on the outside of the metatarsals and the run the motor through the hand. Then you might be able to put four more motors into the palm of the hand. I've been very interested in replicating precise human motion and find that virtually no one has been able to do it. there are so many misinterpretations of human emotion. It's very interesting. Also you might consider trying to rap a flex and extend or tendon around the same pulley. You would still need a knot somewhere I suppose. and I think you should go forward with the wrist design. There's such a wide lever angle that the same motor would be sufficient. it's very exciting but don't forget a raceway for the sensors. Hands need a lot of sensors. Those can be achieved with pager motors. But I like to think smaller solenoids will become available. It's a very delicate business trying to inform the skin, But that kind of sensing makes the hand really complete. I would love to work on the project. But I don't think Google allows people to communicate. Try to contact me if you can. THEUBIE
At this stage no because I just work on this when I have free time outside of work. In the future though it would be my dream to do this work full time amd develop things further
@@nohbellalremli3700 with some research and some patience I bet you'll figure it out! thats what I'm doing! but my project is something completely different, and not at all even close to bionics. but I find this stuff so interesting anyhow! but if you want to learn more on how it all works, the components and how to create your own, I can only suggest find either a study on the subject or try research on your freetime! :) as there is no golden tutorial out there to teach you everything, trail and error my friend! its part of the fun cheers!
Love your work! It's great to see this project coming together 😀
Great idea with the elastic cord, hadn't thought about that. Looking forward to seeing this all coming together
Such a smart design. You're really an inspiration
keep it up buddy! love the documentation!
Nice job...very impressive, it would be nice to see more about the assembly

this was very useful , thank you!
Nice work
Thank you so much sir
Amazing
great !!!!
Have you tried using a torch to blaze the surface of the 3-D printed material and see if it provides a nice glossy finish?

Hello. What material did you use for 3D printing the parts?
what is the difference between micro gearmotor and the servos in usage and control ? and which is better for prosthetics ?

i need to know from where i get on micro motor like it ..did you bought it from site or something other?
You can search micro metal gear motors, various suppliers sell them
Upto how many degrees can the micro potentiometer measure?
what 3D material did you use to print?
How can i get the pins of the finger please ? i need them for my project and live in germany
Check pins from accu.co
What materials is this you used when making the hand
Nylon from an SLS HP powder printer
Hi! Would You like to share details about this elastic rope?
Hi, its called polyester elastic cord
@@MahdiDesigns thank You :) and What about the motors? And Have You shared the CAD/STL files already?
They are N20 motors. No, I'm still developing this, i haven't shared anything at this stage
@@MahdiDesigns thanks for help!:)
what is the name of potentiometer
Bourns micro potentiometer
@@MahdiDesigns Upto how many degrees can it measure
@@Anonynnsn Datasheet says resolution is "essentially infinite". I found resistance changed with small increments of about 1 degree
My brother has polands syndrome on his right.. He has hypoplastic fingers and palm..can u make him a hand
At this stage no because I just work on this when I have free time outside of work. In the future though it would be my dream to do this work full time amd develop things further
can you share files and code
just learn
No sorry
@@MahdiDesigns can you do course how to write code
and how to design hand
@@nohbellalremli3700 I'll try my best brother
i want to know where to get that sensor and its name please i want to learn bro
