Uploaded New Starting point file for Left and Right hands. Files feature numerous changes including:

-Revised Thumb mounting point, for better printability and reduced clean-up.
-Revised Fingertips so elastic and control string can be attached more simply.

You can download the assembly and parts manual here on Thingiverse "Thing number 64720": thingiverse.com/thing:64720

Both right and left hand files are now available. Due to the large number of individual parts, the easiest way to access the STL files is to extract them from the .thing file using Makerware. To do this, delete everything on the build plate except the part you want to convert back into an STL, then click file "save as". Under the "file type" drop-down menu, select the ASCII STL option.

An updated version of the complete hand file (2.5) and thumb mount (2.5) are now available as of 2/4/13. The new version includes:

-improved function developed after further experimentation with the hand. It also includes improvements to the hand's aesthetics courtesy of Chris from Anthromod.

-an improvement to the cable guide for the thumb mount, as well as the addition of a bungee anchor on the thumb mount.

-The addition of extra mounting holes on the thumb mount

-The inclusion of the cable guide/anchor blocks used on the "Gauntlet"

_________________________________________________

The device in its current state can be assembled by using 3mm nuts and bolts in the holes provided. The fingers have guide holes in the top and bottom. The holes in the top are for return cables (Robohand used bungees) and the holes in the bottom are for control cables

Notes on printing:
We advise that the thumb mount and hand mount bar/wrist hinge be printed at 100% infill for maximum strength as these parts are subjected to the most mechanical stress. For the rest of the components, our expiriments suggest that 20% infill is sufficient. All of the parts were printed with a layer hight of 0.2mm.

This device was then mounted on a "gauntlet" made from thermoplastic. When the wearer bends their wrist, it causes the cables to be pulled and thus flexes the fingers. we have completed a manual for assembly. This will be available on our blog..

Using Makerware, it could be scaled to fit a wide range of individuals. The only thing that would need to be changed is the size of the bolts purchased from a hardware store. The design is open-source and in the public domain. We encourage anyone who can make use of this design for any purpose to do so :)

The parts shown in the pictures were fabricated using a Replicator 2 that was given to our project by Makerbot. Thank you Makerbot!!!

miguelnavarrete on Jan 27, 2014 said:

Hello
I managed to print all the components listed, but how do I print a thumb mount for a left hand? The one here is for a right hand
Also, I couldn't find the files to print the wrist brackets and the bridges.
Thank you

CoreyHettinger on Jan 31, 2014 said:

I figured it out Miguel, just download the Left Hand Starting Point 2.6 file and it has all the parts that you need in one place, just open it on the Makerware software that is free to download and scale to size and then print.

CoreyHettinger on Jan 30, 2014 said:

I am having the same problems, I really need the updated print files for the bridges and wrist brackets, I am also making a Left hand, It is for my younger adopted sister sister.
Thank you

ariana on Dec 4, 2013 said:

I'm a senior in high school in an engineering class and i'm going to do this for my senior project. Is there any way I could email you along the way to have you as a mentor to this project? Thanks! -Ariana

jspatz1 on Nov 24, 2013 said:

There appears to be a mixture of scales for parts in the latest Righthand 2.6 thing file. The proximal_phal and the anth_hand_mount_fixed are at a larger scale than the rest of the parts, so they do not fit.

orgemd on Nov 24, 2013 said:

Thankyou for this project - it is wonderful! I am in the process of making one for my sister. I was wondering though if there is a technical reason for the equal length fingers. I was planning on making the the finger lengths match those of her other hand. If you already tried that, however, and found it leads to some problem so that the hand mechanics stop working, then I would rather know to not go that route. I do understand that I will not be able to just scale the parts, but will have to redo the 3D mesh to change the length. Also, is there any chance you can post a vendor/part number for the threaded brass rod and the the brass cable lock? I have not been able to find those parts.

Thanks again.

-David

Das ist eine großartige Leistung die Sie dort gebracht haben.
Seit meiner Geburt fehlen mir an der Linken Hand die kompletten Finger, genauso wie den Jungen in ihren Video.
Ich habe hier im Deutschen TV einen Bericht über ihre Erfindung gesehen und bin seit dem ich es sah vollig begeistert und möchte auch eine solche Prothese haben .
Die Möglichkeiten die sich mir dadurch allein im Arbeitsleben eröffnen sind grandios!
Ich danke Ihnen dafür, dass sie dies erfunden haben .
Bitte kontaktieren Sie mich

You are awesome! I have a son who is 9 adopted at 3 yrs with no fingers on the right hand and a partial thumb. He saw this and now wants one! My father had the same limb difference and while quite capable always wondered what it would have been like to have fingers. I have contacted the USA site as I have no idea on how to proceed.:}} Great job!!

Nik180 on Sep 22, 2013 said:

I downloaded the robohand and i cant seem to find all the pieces, the ones that go down the forearm, and the two pieces that go's on top of the hand and arm, that the string goes thru. I am trying to make this for my friends son who just lost his fingers in some sort of farming accident. Please help

Hope this helps.... It has assembly instructions for it but it was kinda hard to find...

farieda on Sep 21, 2013 said:

Good day, I have a daughter that was born 26 weeks premature. When she was 2 1/2 months old I picked up that she had floppy wrists. She is now 3 turning 4, doctors still have know diagnosis for her but was wondering if this robotic hands would work for her? She's been for a nerve conducting test about a month ago and they found one of her three main nerves in her arms but not in her hands. Everything is developed but is unable to write, catch a ball, etc.

rjmehra on Sep 18, 2013 said:

Unless I'm mistake some pieces are missing. Looking at the instructions, and many images of this, there should be some longer pieces that go down the length of the hand/forearm. Just curious, sorry if I'm wrong.

scorbi on Aug 21, 2013 said:

Dear Mr.Rich. First of all, I very admire your creation, what an amazing work. I just wonder could you make an instruction in making the hand cap as well as the gauntlet? I would like to contribute something for my local, however the assistance from an occupational therapist is not likely alway available. Best regard.

RevBuddyLove on Jul 31, 2013 said:

Hey, do we have a part list associated with a vendor for easy ordering? I'm not sure how to go about getting these non printable parts.

robohand on Aug 16, 2013 said:

All hardware is imported from the USA. You should be able to find it.

Claudio10 on Jul 30, 2013 said:


Hello, My name is Claudio, I'm from Buenos Aires, Argentina. I have a son called David of 8 years old, who used to use a mioelectric prosthectic hand since he have 3 years old. That was heavy and at the end he didn't like to use it anymore.
I was praying to find something light and versatile, and yesterday looking for in internet I found your creation and I felt impressed. So, I thougt this can be the solution!
Now I would like that my son use your robohand.
I appreciate all your work done and how your work can help a lot of people around the world.
Please how can we get in touch.
I'm very interested.
Thanks

robohand on Aug 16, 2013 said:

email [email protected] please include photo's of your sons hand/arm and the above information.

alextheapples on Jul 26, 2013 said:

Hey, on the ABS Robohand Assembly Manual there are a list of materials that we need to build this hand and it says that you can purchase a start up kit and a growth kit. i tried to find the start up kit with no luck. Can someone send me a link to the start up kit?

Also, for the bungy cord in the ABS Robohand Assembly Manual does it have to be a certain thickness?

Thanks.

Mysabre73 on Jul 19, 2013 said:

This is amazing. Thank you for the work you do. You are bringing hope to people who otherwise would be without. This condition is new to me. I don't know anyone with it but I am moved by your work. Thank you.

Kulitorum on Jul 10, 2013 said:

There is only one "string" per finger? - How does the fingers "open" ?

robohand on Jul 10, 2013 said:

On the top of the finger. bungee cord. which returns the finger to the open position Bottom "pull string" this closes the finger. Cheers

susyanddavid on Jul 10, 2013 said:

Hello, I live in Guatemala and a have a 1 year and 7 month old daughter who has stubs in her left hand, she has her thumb and the index finger but smaller than her right hand and stubs on the other three, I found Richards story and was so amazed to see it, I've been wondering if it's possible for my daughter to use the robohand at this age and if there is a way for someone to help me and how to acquire it. I appreciate what all of you do here!!!

CafeBikeGirl on Jun 20, 2013 said:

Hello, I believe the appearance and dexterity of the hand could be improved by modifying the following design to fit the arm as yours does:

I have messaged the creator to recommend his involvement.

kojote on Jun 19, 2013 said:

For those of you without Makerware to open the .thing format - just rename it to .zip and unpack it - it contains the single .stls for all parts

jerristone9 on Jun 18, 2013 said:

I meant to say that my son is now 20 years old.

jerristone9 on Jun 18, 2013 said:

My son, who is not 20 years old, was born without fingers and most of bones in his left hand. He did not have amniotic band but his fingers did not form. He has a fairly functional thumb. We have always wanted a hand like this! I don't know if I am clever enough to make one but ... I want to . Where do I begin?

kojote on Jun 19, 2013 said:

To start - find a Fablab or Makerspace or Hackerspace in your area.

Good point to start would be here: http://hackerspaces.org/wiki/L...

Ask them (politely) if someone is willing/able to help, maybe by printing the files or assisting you with the assembly.

Corona688 on Jun 8, 2013 said:

You don't actually need a Makerbot to install MakerWare. It is not license-keyed and does not care whether you have a makerbot plugged in or not.

phredgsanford on Jun 8, 2013 said:

donstratton"s post x2. I have a Makergear M2 and I'd like to help out/use this as a real world example for my students. Please make it as easy as possible for nonMBI users to contribute.

kojote on Jun 19, 2013 said:

You can download Makerware and export .stl Files from there too afaik . but I'll nudge Richard to also releasing all files as .stl

donstratton on Jun 5, 2013 said:

One small observation... there are a lot of 3D printers that could do this work, and Makerbots are just one of many, so tying this in with Makerbot software seems rather limiting. I, as the owner of a Lulzbot, apparently cannot do anything other than print the example STLs. Am I missing something?

kojote on Jun 19, 2013 said:

working on that - gimme a moment

mjhmilla on Jun 5, 2013 said:

In October I will be teaching between 50-100 graduate engineering students about multibody dynamics. I'd like to point them at a meaningful project, and this hand certainly qualifies! They will be able to simulate and predict the kinematics and loads the hand is subjected to as it moves, and even some stability properties. I'd love to work with you to design a project that will help your efforts. Please get in contact with me if this appeals to you - matthew.millard at uni-due.de

robohand on Jun 6, 2013 said:

Hi Matthew. It is open source. So you can do so. other guys have done what you planing to. they did however use some of the fee's charged for teaching and made a donation that resulted in two kits that were made up and sent to help people. if you do have some good idea's and they work for enhancing the hand. pls post it back as a remix. It is possible to make things better and this will just benefit everyone. please do keep costs in the forefront of this too. the idea is to make it as cheap as possible and functional. within the reach of the less fortunate. Cheers Rich

dreamingdigital on May 20, 2013 said:

Hi everyone
My name is Francisco from Spain. My nephew was born with amniotic band syndrome and he is mising the fingers of one of his hands except for the thumb. He is 3 now. He asked the other day why he couldnt have another hand to play like his twin sister so I started looking and found Richard's project. I'm looking for help from someone who have a printer to make the parts, of course i would cover all the costs involved but i need someone with the hardware and expertise to make the parts so i can build it for him, if there is someone out there please contact me on [email protected]
Thanks in advance
Francisco

funsolid on May 22, 2013 said:

Hi Francisco and Rich. We would be very pleased in helping you as far as we can. We are very interested in collaborating since we knew this project. I´ll contact both of you by email cause I´m sure we will need Rich´s help and advice. [email protected]

robohand on May 21, 2013 said:

Hi Francisco, I sent you a mail. will help with pleasure. Regards Rich

GatorALLin on May 20, 2013 said:

Hi, love this project...... Just wanted to say that I was searching on Indiegogo and could not find you with the search of "Prosthetic" or "Hand" and think you should add those critical tags there. I just made a donation there as well. Keep up the good work. I have a Replicator2 and lots of PLA material and would love to print a few extra sets of parts if that would help anyone. Just request a color and where to ship the parts or any other details. I just got in some glow in the dark PLA and a few bright colors in.

bauerwer on May 19, 2013 said:

Simply awesome! My son was born with no left hand and the lower left arm stops shortly after the elbow. I wonder if this would work with an extension that sits in the arm (held up oever the elbow. Most likely, the impulses for the finger(s) would be a problem. The nerves and bones are present in the small lower arm piece, but could those be used to trigger the gripping?

robohand on May 19, 2013 said:

Hi, I have a set of arm extensions . they are not plastic or printed tho. Send me a mail to [email protected] then maybe we can get a design down for your son. cheers Rich

amitnpujari on May 16, 2013 said:

Hi guys, excellent work! I need your help in start making robohand in the UK. I have sent you an email at [email protected] and [email protected] It would be great if you could reply. Thanks!

AWESOME MATE!

Tactyle on May 10, 2013 said:

You mention in the video that with this prosthetic hand you could ride a bicycle.
I have a question about that; Is it possible to hold the bike handle with the prosthetic hand while using 2 fingers to pull on the break?
Would such an action simply make the hand led go of the bike?

Austin on Nov 5, 2013 said:

Hmm, it would probably be safer to re-cable the bike so both brakes are on one hand. I did a quick search, and found a number of models for sale for just that purpose (where one level accepts both cables).

Toby22 on May 10, 2013 said:

Very impressive!

Zoopers on May 10, 2013 said:

This is absolutely amazing. Completely awesome! I would love to print one of these for someone that needs it.

colinfizgig on May 10, 2013 said:

Fantastic! I reached out to you by email about my son Charlie. I'll download these files and start printing today to see if I can give you some feedback. Thanks for all your work.

GarrisonTECH on May 9, 2013 said:

I have been on the Thingiverse for about a year and have seen some really amazing functional "things" here, this is the tops!

I have a student in my class that has one hand that would be very interested in this.

Thank you for your hard work on this project.

kojote on May 13, 2013 said:

Would love to see some pics of the finished hand afterwards

OpBots on May 9, 2013 said:

You sir, are my hero!

The idea of using 3d printers to aid in the making of prosthetic has been a dream of mine, and you are truly an inspiration to my cause.

THANK YOU!!!

To everyone offering assistance – thank you very much. We would like to try and co-ordinate where everyone is all over the world so please send an email to [email protected] with what type of assistance you can offer, where you are on the globe as well as your contact information. Thanks!

NoobixCube on May 9, 2013 said:

I wonder if this could be adapted for use by someone with fingers, as a power assist glove. Mum has MS, and sometimes her fingers don't feel like moving when she tells them to.

robohand on May 9, 2013 said:

Hi. thanks for the positive comment. To answer the question. if you look through the thingi's you will see the start of the exoskeleton. if you are a 3D print bof and script. I will most certainly assist you with some design plans in Sketch form and you can then get creative. Limitations are in a box. throw the box away before you start. Cheers

koolhandkc on May 9, 2013 said:

this touched me. i'm compelled to design a "glove" made of a sugru or oogoo substance to give it a more human feel and look. hmmm. i guess i need to give it some thought. outstanding post robohand! this is what the creative commons community is about.

robohand on May 9, 2013 said:

Yip! a lot more thought. There were to main objectives with this. Affordability and function. once you have managed to find medical silicone which is "not poison" and you have a medical practice no to buy it. it will become clear why I would go this route. I always say. if it ain't broken don't fix it. Cheers and thanks for the post. Rich

This message is specifically for lakefern, but it could benefit others.
Try this website, they may have a solution: http://bcove.me/z8mykift
They created a full rig for a child who could not move her arms, and now she can.
Hope this helps.
I'll pass this website and the other one along to anyone that needs either of them.

Dunno why Richard hadn't posted it yet, but they are running a Funding Campaign right now that could use your help: indiegogo.com/projects/robohan...

lakefern on Apr 13, 2013 said:

this is amazing! my teacher is the co founder of a foundation called the getty owl foundation. they are funding devices for SMA (spinal muscular atrophy). if you could figure something out as a sort of exo-skeletal pair of arms for people with SMA then contact me. Thanks!

dulanto100 on Apr 8, 2013 said:

Hi there! so impressed!!
I am a school teacher, teaching technology, using Inventor autodesk, have recently acquired a 3 D printer from makerbot, would like very much to use this hand as a project for the class, have a graduated student who needs this wonderful device, could you please give me manual, assembly instructions etc.
for such projects. Thank you

socheltree on Mar 20, 2013 said:

I live in Bellingham Wa. My 9 year old son was born one-handed. I am very interested in trying to make one of these for him, but have never worked with 3D printing. I'm sure you're flooded with requests for help, but here's another one. :-)
If you could contact me I'd really appreciate it!

robohand on Apr 29, 2013 said:

Hi. Apologies there is a chap in Bellingham that can help you with the printing of the hand and possible the assemble there of. Let me know if we can assist you. Please send me a mail and I will send you his details and make contact for you at the same time.

If Richard didn't contact you yet (busy busy man) lemme know. My email is [email protected] - i live in Germany but i have contacts to all over the US and people capable of 3dPrinting. Would love to help

NCPete72 on Feb 15, 2013 said:

My 5 yo son was born with a left hand nearly identical to Liam's right from symbrachydactyly. This device is amazing. I've located a 3D printer here in North Carolina and I've down loaded the files to my jump drive. How can I get assembly instructions? And I may be mistaken, but are the specs for the gauntlet included? I want to produce one of these for my little guy so badly; I cannot wait!

robohand on Mar 20, 2013 said:

Send me a mail to [email protected] I will send you the assembly manual. Cheers Rich

robohand on Feb 15, 2013 said:

NCPete72 - Please contact me at your earliest opportunity. We've been swamped with a large amount of work, and the tutorials & further constructions are under development, but I'd be happy to work with you directly while we get the instructional materials finished.

Please email me at [email protected] and I'll let you know what the next steps are and provide you with guidance on how to assemble and fit the device for your son.

If you can do so today, I will be able to give you a response within 24 hours as I have some time blocked off on my schedule for answering emails.

Thanks!

tuficn on Feb 10, 2013 said:

I'm a 15 year old who is really interested in making these and giving these out in my community for free. Can I use it to build robotic hands and present them to my school on how I was able to make them and give them away? (it's a free project and I'm building my own 3D printer and showing things you can do with it)
Thank you!
PS. I will give you all the credit of the design and all!

kojote on Apr 29, 2013 said:

Sure you can build them - it's licensed under Creative Commons. Good luck

katrie1055 on Feb 10, 2013 said:

When I saw this I nearly died. My grandson was born no left hand caused by ABS (Amniotic Band Syndrome) and his name is Liam. I just think you guys are awesome and hopefully someday my little baby will be able to use something like this. He does remarkably well now but as he gets older and really starts to use his hand/s, this would make things so much easier for him. Thank you for what you do and don't ever stop!

momhand on Feb 7, 2013 said:

This is so crazy cool! My son, adopted from China when he was 2, was born with missing fingers on his right hand (symbrachydactyly). He is about to turn 7 in a few weeks. I'm not really sure how we could do this, but just the possibility is so amazing! Thank you!

robohand on Feb 15, 2013 said:

Greetings Momhand!

Please contact me via email and I can speak with you further about how we might be able to help. I can't say for sure if there's a way to adapt it, but we're willing to take a look and at least try :)

Please email me at [email protected] and I'll send you a response with next steps & some questions that will help us get a better sense of what the possibilities may be.

Thank you!

This is very inspiring, and not easy - Excellent job. I am honored to be working on a highly advanced prosthetic hand & arm for wounded veterans. However, it won't be for everyone, and isn't meant to be. The (fortunately) small market and unbelievable volume of paperwork keeps many companies from even attempting such feats, which is really infuriating. Please keep doing what you are doing - helping kids & inspiring so many others.

cool

ThePlanetMike on Feb 1, 2013 said:

Have you considered making a design that actually is "his" hand by using the free program, 1-2-3D Catch, to 3D scan his other hand, then mirroring his fingers to make the new hand? It may not be worth it if the grippy thimbles work well, and it would be hard to incorporate your already excellent design, but I do think it would be possible. It might offer him a more natural look if he cares about that now or in the future. Let me know if you'd like to discuss how that might work. I'd be happy to help.

You are changing the world and are an inspiration for us all to emulate. Thank you!

Parenting, You're doing it right.

Thats Great! There should be more things like that!!!

This is so inspiring!

Absolutely brilliant! I think this begs the question, where are the Thingiverse Awards? :)

jasonwelsh on Jan 26, 2013 said:

wow that is hard to compete with, I mean helping kids and adults with missing fingers. The next thing will have to be a printable fusion reactor to top that.

Screwing the company that makes these things for huge dollars + huge insurance costs + insurance premiums screwing the next poor kid... I love this stuff!!!

Stephenwinter on Jan 26, 2013 said:

Wow, You helped thousands.

Forgetful_Guy on Jan 26, 2013 said:

You guys rock! And I am sure you will keep rocking in the future. I wish you all the best. I am studying to be a mechatronics engineer, and one of my ideas for the future (job-wise) is also development of practical affordable prosthetics. I admire your dedication!

thecrazy on Jan 26, 2013 said:

Wow, there should be a website dedicated to open source prosthetics designed to be 3d printed. Very cool stuff your doing.

I think there is one, but I can't find it...

I like this device. Very neat. I am working on a plastic pin set for this so I can mess around with it without using metal hardware. Probably won't hold up to heavy use but should be fun as a desk toy. Can you post your source file so I can work on improving your design?

robohand on Jan 26, 2013 said:

Certainly. I'll upload them within the next day or so and send you a message when they're available. Just a heads-up though: The files are in OpenSCAD & my code is rather disorganized and lacks documentation at the moment. Rich and I made many changes on the fly with the focus being on getting Liam's hand ready for him ASAP, so I have yet to take the time to clean it up.

If you don't mind wading through the messy scripting, however, we would very much welcome anything you can find to improve! :)

unknownhand on Jan 25, 2013 said:

This is good:). I have another boy in mind for it too. His name is Power and he lives in the Philippines. His left hand was malformed at birth. Quite cool.

robohand on Jan 25, 2013 said:

Excellent! This is exactly what we were hoping for! Other individuals using this design to help either themselves or people that they know. Do you know Power personally? If any of what we have learned by creating this for Liam could be of use to you in adapting the design for him, please let us know. Send a message to us at [email protected](Ivan) and [email protected](Rich).

Thank you!

Great work! I guess that seeing that nice smile on the boy's face should be the best reward you can get!

robohand on Jan 24, 2013 said:

fma - you are absolutely correct :) The greatest moment is when Rich and I were working together with Liam in South Africa. The moment Liam realized that his wrist motion powered the device, he exclaimed "It copies me!!".
