Assembly of 3D Printed Prosthetic Hand | From Thingiverse

The original files and designs are at www.thingiverse...
This is a project I have been working on for around a year and a half now, and this is close to the final product. However, before it is completely done I will need to touch up on the code and find an amputee to test it out. The overall price is a little under $100 for shipping to the US, it uses 2 servos (1 for the thumb and 1 for the other 4 fingers) and is controlled by a Myoware muscle sensor. I used some more powerful servos for added strength, but standard servos can also be used. The materials are:
Servo
www.banggood.co...
Battery
www.pololu.com...
Flexible Nylon Paracord to pull finger back
www.paracordpla...
Arduino Nano
www.banggood.co...
Rubber Sheet
www.ebay.com/it...
Fishing wire anywhere
I strongly support any improvements or modifications to the arm, if you have any I would love to check it out! You can E-mail me at grossrc46468@gmail.com also if you have any questions you can ask me.

All the code used in this particular video can be found at my partners GitHub page here: github.com/tt-anderson

@inso5078 5 лет назад

I've tried many different types of joints to connect all the segments of the fingers, and you just skipped that part and used it as both a joint and a spring. Which seems like a pretty smart idea, but I think it would look and work better if you added something for positioning the fingers, so that they would stay exactly in line.

@ryangross6886 5 лет назад

What I've found is that although they sometimes do get misaligned, they immediately get realigned when pulled shut. Then they open back up perfectly straight.

Thank you! I checked out your video and it's really cool, I got the arduino nano board at m.banggood.com/ATmega328P-Arduino-Compatible-Nano-V3-Improved-Version-No-Cable-pnew-959231.html And the board fits in the screw sheild which can be found here m.banggood.com/NANO-IO-Shield-Expansion-Board-For-Arduino-pnew-963967.html You can get all the files and other material URLs at my Thingiverse page in the description, and I was also wondering if you go to MIT?

@TheJp0996 7 лет назад

How much is this video sped up and how long did it take you to assemble?

@ryangross6886 7 лет назад

It took me about 2 hours to make the entire arm having all the pieces and tools present. The servos both go to pins 8 and 9 like you said and the battery power goes to VIN (+) and GND (-) and the muscle sensor goes to the 5V pin the GND pin and the A3.

@kibyjohn2368 7 лет назад

Hello I am Czech and I want to thank for this video because I have a deformed hand and I can not move my fingers, and this video inspires me to make my hand, Otherwise, I think we will not have to buy a prosthesis on your hand or foot, just print it in a 3D printer :-))

@jcookev 7 лет назад

Hey Kiby, were you able to create your own prosthesis? If you haven't solved your problem yet I would love to help you get a 3D printed prosthesis as part of a project I'm currently working on! Best of luck! :D

@briellejeffries272 7 лет назад

How successful do you think this particular hand it at picking up objects. What would be the weight limit? Also, is there any way you can control each finger separately and not just all the fingers and then the thumb? Replies would be greatly appreciated, thanks.

@ryangross6886 7 лет назад

This hand is very good at picking up objects with the opposable thumb, the weight limit is around 6 or 7 lbs. even though we haven't officially tested it yet. As for the control, each finger can be controlled individually except the ring and pinky finger which move together.

@markwenk9035 6 лет назад

how long would the battery last? would an all day application last?

@see3d958 4 года назад

I am assuming a all day application should last, but there is a reason that the battery is recommended to be rechargable. An idea would be to charge the battery while you sleep, then attach it onto the arm in the morning.

@edwardlyles1098 3 года назад

Sorry I am not understanding something. So when attached to the amputee how do they make it move?? thinking about making one and need to understand before I start

@eliseysytyi1561 3 года назад

You need to flex the muscle to move the prosthesis.

@limalshaji6788 2 года назад

So super super basic run down of this, if they didn’t have a hand, they would utilize a different muscle, like a bicep or a for arm muscle, and through the flex of the muscle, the muscle sensor will read and interpret that, thus causing the hand to clench/release depending on the code

Although I've never formally tested the grip strength, it is surprisingly strong. More than strong enough to grip a soda can or water bottle for example.

Does this hand follow your own hand's movement?! Or what kind of sensor do you need to get for that ability for the hand to follow your own arm's movement?! Really curious and NEED as much as info possible!! Also any possible way to find the thumb of the humanoid hand?!

@ahonisunar7622 7 лет назад

really new to engineering, so i'm really confused, thank you so much for the video.

@Frank-yb4zd 7 лет назад

the sensor is called the MyoWare Muscle sensor. you attach the sensor to any muscle on your body, and when the muscle is flexed, it outputs a signal.

I use a myoware muscle sensor which has electrodes that clip on, then the electrodes are placed over the muscle that is going to control the arm. I have a very basic setup right now where you simply put on the electrode and when you flex, the robotic arm closes.
