Thanks everyone for your feedback & nice words! I designed this arm at University & have now been working as an engineer for several years. With my improved skills & experience I am hoping to design a new and improved prosthetic arm. I would like to make this new arm more durable and actually attach it to an amputee. Subscribe to the channel and stay tuned for this in the future.
@@bill8065 I guess so! Besides just some early concepts I haven't done much work yet on a new arm but I'm hoping to start designing in the next few months and document the progress on RUclips
It is amazing all the work you did and I hope you are still working on. I have started to research more about this to try to help my young cousin which unfortunately just lost his arm in an accident. I know it is going to be hard for him to adapt but thanks to people like you there is going to be more possibilities for him and millions of people in this world. Thank you!
@@efraingutierrez9766 Thanks for your nice words. I am still working on this, there are some new videos of the new design on the channel. Best wishes to you and your cousin
Sharing own experience and information is precious behaivour. Thanks a lot bcz your video helped me to solve my own problems about my prosthetic arm project.Great job .
Awesome job!!! I'm super impressed you took on such a project for an undergraduate thesis! How you fit the time and effort for such a big project amongst your other modules in a final year has blown my mind, no wonder you achieved a high distinction. Well done sir!
Awesome article, I built some robotic arms back in the day so I want to just comment that the further towards the hand you move the servos (or any weight) the more leverage this weight has on your servo elbow motor reducing its load capacity. Ideally if all the motors could be moved into the shoulder region that would significantly lighten the load. I understand that having room for everything was a problem & influenced the design. Well great job and hope to see more from you in the future.
Thanks for such an insightful video in this topic. I have just been given this for my final year project and had some ideas similar to this. i feel alot more comfortable now going into this, except the electronics part with me being mechanical. brilliant video once again. Thanks!
Dude thank you for this video, I'm trying to go to college for robotics engineering and this video helped me understand a lot of components to your design. Helps a lot!
You're very welcome, it's seriously impressive work. I'm reading you thesis now, the amount of information and research you have done is extrodinary and fascinating. The amount of time you must have put into this project is very admirable. Can I ask what you are doing now? Did anything come from this project?
@@KieranMeadows Thanks so much! I put in a lot of time to this project, probably the eqivalent of full time work for about 9 months. Some students continued this work in later years to write their own thesis'. I work as a robotics/mechanical design engineer now, it's great. I actually do more advanced and robust designs now but I can't really share the details of the models I make at work. Darpa (US military) is doing amazing things with prosthetic arms. All the best man 😊🙏
First of all, let me congratulate you mr. Hussein, it is so incredible that you could do all of this for your thesis proyect, I mean its awesome, I´m thinking in doing a prosthetic limb, so allow me to read your thesis to learn about your experience and see what I can do, thanks :)
Hey sir thank you so much... I'm a mechanic engineer student from India i seen this video and i want to do the useful things for people who are handicap and this video is very useful for me. U done very awesome job.
Thank you so much this help me very much for my final year project. I have taken refrence of your design and I have design some attchment so it can be attached below elbow to amputees. But the problem it's weight is much. Practically it is not comfortable for amputees but I did it for educational purpose. Without your information It was not possible to complete my final year project. Thank you So much Once again, you are doing great work. Keep it up👍🏻😊
Many Thanks for publishing this video description of your project. It informs my design for a full robot. (I am looking at incorporating some of the ideas ). This is a retirement project, so something I'm doing at the opposite end of my career to your own project.
You are doing great work keep up . I'm 26 year old men I don't have right hand (below elbow) D and I'm looking forward to your research and progress you will change a lot . Thank you
Hey whats up? Check the company OPENBIONICS, they have affordable below elbow printed prosthetics.... they are stylish and very functional. Hope it helps you!
Im in a class named gate for kids who do better in school and our project is to create a hand that is able to pick up a piece of paper. Its random but its inspired me to become a bio medical engineer
Thank you I'm trying to design a prosthetic arm for this character for this short story I'm doing for a contest. I'm gonna go buck wild serious like I'm actually in engineering university doing this for a thesis thanks again for the help!
Great work sir. It is nice that you put so much details in the thesis and even share the models here. thank you so much for sharing this... God bless you
I've been trying to build a bionic arm, but most resources are scattered on the web. But this video made more sense than all the papers I've read. Thanks, man!!!!!! (and could you help me with my bionic Arm project? I'm having a lot of trouble getting it done )
Hello! I am 17 years old, I and my friend are working on a prosthetic arm project for Intel ISEF. Your design of the arm is really interesting and useful for us. Can I contact you via email to learn how you made your model? It definitely would be really helpful. Thank you so much!
First of all great work... Your work helped me with starting my final project. I am having a bit of trouble with the ADC as in writing it in my code. I'm use a PIC microcontroller as I'm not allowed to use an arduino (easy to use). I have gathered the EMG data using a data acquisition board but can't seen to implement it correctly in to MPLAB. can u please help me with this? Thanks
Thank you! It has been quite a long time since I have used mplab or a pic micro, so I can't remember too many details. I would suggest starting small, look up tutorials and write a small segment of code, test it, make sure it works then build up from there. Good luck!
im not a robotics person, however i have to research bionic arms because my character for a project has one, it helped me alot with understanding the arm
This dope! I’m currently a senior and I’m trying to decide what career to take. I want to build my own bionic prosthetic and I’m not sure what engineering path would lead me to that. I’m thinking either ME, EE or BME but I’m still not sure I would love your opinion on what is best
Hi i am came across your project i saw the video of prosthetic arm working. I also am doing a project using emg sensors and i find it hard for programming ,can you please me the program you used for this project so it might be helpful as a reference to me.
Hey man great project!! I saw the google drive folder, but I was wondering : What standards should this hand follow to comply with professional standards?
This is amazing Mahdi (thats your name right? I stalked you thesis lol) Im current a 3rd year Mech at UQ. Would like to get into Biomedical devices. I also love tinkering and getting hands on like you (no pun intended) so this is a huge inspiration for my final year thesis which I have to start thinking about soon. Not sure if I could do a full prosthetic arm like you can, but your project shows whats possible if you have a crack at it. Awesome work mate, keep doing what you do
Hi, that is my name 😁 Thanks for the comment. I would recommend just starting small like a finger/hand, or the equivalent for your project. Then depending on how you're going for time you can build upon that. Best of luck
Hello Sir , thank you for sharing your amazing work with us , can you tell me if the CAD you did is originally yours or inspired from open source models ? thank you
Yes it's my original design. I did research other designs snd projects first though. You can read details in my thesis on my website, link in video description.
Hi! I really enjoyed your work! I'm also doing a project on myoelectric forearm prosthesis, and was wondering... how you approached the coding/programming- my friend suggested machine learning but i dont have time to do that and lack knowledge, do you have any suggestions? Also, how do you increased the degree of freedom? I have a limited budget and would like to use myoware, but to increase the DOF do you think it's possible with only 2 sensors? Thank you for your time:)
Hi, thanks! I would suggest looking up arduino tutorials on how to control servo motors, its not too difficult. You can also look up tutorials on reading an arduino analogue to digital converter. With those two things you can read the myo sensors and use that to command the motors. Machine learning isn't necessary to start with. DOF means how many different movements you have, you can always use more myo sensors to control the additional degrees. Best of luck!
@@MahdiDesigns thank you so much for your reply, very useful!! Also did you consider the biocompatibility of the materials you used, ie mechanical properties of the materials you used? If not, how would you have evaluated the biocompatibility of the materials used and the over all prosthetic device? ☺️
Do you happen to know the problems that would occur in using your left hand’s pressure of holding a writing utensil and being able to use it? Like is there a way to capture the the movement it takes for a hand to hold it and develop a code for it and have that used for when certain muscles are activated at one time?
I'm not sure I fully understand but many muscles work together to hold a pen for example. The sensation of touch/pressure provides feedback to allow the brain to make micro adjustments. A prosthetic hand needs many degrees of freedom and some form of feedback to the user to manipulate objects in a similar manner
Hi mahdi, nice work but the Thesis Paper link isn't working can you provide me with another link if you can. As I'm working with a similar project and I need to read it. thank you.
Hi, really love your work I’m doing something similar and I want mine to have that proportional action where the grip strength depends on the voltage, what would you suggest I do?
Nice, that would be cool. You might want to smooth the EMG signals, either with a circuit or maybe just reading say 10 times and averaging. The raw signals can be noisy. Also, with low end hobby servo motors you can't really control the torque. To the best of my understanding you can only control their position and they will use their max torque to get to that position. With DC motors and your own controller you can however control the torque, so you could use the EMG signals to proportionally adjust the torque. I may do something similiar to this on the new project I'm working on as I'm using micro DC motors with motor control driver boards (motor drivers from Pololu). Hope this helps
Hi Sir i'm from algeria and i've a neighbor who needs an arm and i decided to make him one but i dont know how to start i' like your work and if only can give some help starting by telling me what i need to buy plz and thx
Your project is incredible. The way you've managed to build a proper working prototype from scratch with the amount of information and research is just simply amazing! If you don't mind can I have the entire code of your project? I checked the drive, but I didn't find it! Thanks and congratulations on guiding other students!
Thanks a lot! Unfortunately I no longer have the code, this project was quite some time ago. I suggest looking up how to control servo motors with arduino
Hey man, first of all, great work and thanks for sharing it. I'd like to work on something similar creating my own model, is there any chance you can send me your SLDPRT files to get started?
Hi, i printed your project for a high school robotics project, and i was just wondering how the 'tendon locking point' works, within the finger. Is it a separate piece, or just a certain way the finger was threaded? Thanks!
Hi, that's awesome, I would love to see a photo. I looped the "tendons" through the tip of each finger. There are two small holes which allow you to loop through. Best to loop multiple times so it doesn't slip, you could even use a drop of super glue to really make sure it doesn't slip
Hey! First of all awesome that you've built this arm. It looks awesome. I would like to ask you though.. Is this suitable for someone who has no underarm and wants to use this as an actual replacement, or is this more a part for a robot? I know that u could probably use it as a prosthetic, but I dont see those things amputees have on the insides of the arm to control the movements. How do you intergrate them into the design of this arm? Or do you know who explains this online? You would really help me out since I myself am born without my left underarm, and want to built this myself. Thanks for the video, it's really helpful! Cheers!
Without an underarm would be more complex. Essentially the more that is missing the more complicated the prosthetic arm replacement is in terms of design & control. This model was just a prototype, it wasn't developed enough to be used in the real world. However, an amputee in theory could still control this prototype using electrical pads on nearby muscles. The United States Military does advanced research on prosthetic arms. Search DARPA Prosthesis. In the future the technology will continue to get better and hopefully become more affordable for the people that need it =)
first of all great work u did here, i am working on a similar project like this. i wanted to know how did u classified 6 different motion using only 2 emg sensor??
i am strated a concept model same like this but a Paralysis hand going to be present in side the prosthetic hand cover. can you tell me motion capture sensor you have used...
i am currently in the stage of printing, logging and redesigning your prototype would you want me to send you a log of my observations once it is completed as this should hopefully serve to improve the quality of your future projects?
Wow that's amazing! Great work. Sure that would be awesome. If you like I can also upload your files for others to access and learn from. My email address is mahdihussein.91@gmail.com
hi do you have the solidworks sketch. can you give me the link of the sketch in solidwork if becouse my universete bring me this hand for a virtual proyect but i don't have the measurements please help me
Great work, i am doing same subject right now. I need help on one issue related printing.Merely, i have printed all the parts except bicep Stl file . i have printed that part twice, but during printing it cracks .Would you please guide me related to that problem.
Firstly, I was getting a crack during printing of bicep stl file. Fortunately, i solved that problem and now all the parts are accurately printed in their original form.
What a nice work! I'm from Brazil and for my graduation Thesis I will be doing something similar to your project! I'm really excited for it, but I have one question regarding the independent movement of the fingers. How can you control the fingers independetly, when you have only two EMG sensors attached to two muscles? Wouldn't just your biceps muscle control the thumb and the forearm muscle control the remaining fingers? Or do you regulate it depending on the signal power coming from the EMG sensors? Thank you very much and if you have some time, I would be happy to receive an answer from you. Cheers!
Hi, sorry for the late reply. The fingers I controlled all together at once so not independently. You could also incorporate signal power into control in different ways. Solidworks models uploaded now, see latest video
@@kevinperera6129 If you have Solidworks (maybe you can access it at school) I would take some time to do some of the in built tutorials. When you have some basic skills start trying to model objects you find interesting. You can also buy am arduino (they are cheap) and look up youtube arduino tutorials. Just start small to develop basic skills. You could initially start by designing your own prosthetic finger and using a servo motor to control it. Good luck!
Im a freshman in highschool and im interested in starting a project like this! In the future I would like to be in bio medical engineer.my school has a 3d printer i can use. how can i get started?
Bro i am a doctor. And i want to get involved with this. I want to start creating. So can i know where to start? And how about progressing from there after.
That's great. This is design engineering work. You could start learning CAD modelling (Fusion360 is a free program) and also electronics and software (arduino is a good place to start). Perhaps with your medical knowledge you could find some engineers/designers and collaborate
Hello sir, it’s so inspiring to see your video. I’m also in university and my project is to build an adaptable prosthetic arm using 3D printer. I was wondering if you would mind to share your research paper with me cause I’m in my first year of engineering and really don’t know were to start. Thank you for considering my DM
Hi Mahdi firstly it is very usefull video for me we have a group for final thesis and we want design prostethic arm like you but i have a question for about project How did you position emg sensors ? How can you determine points of arm? Thank you again have a good day
Thanks Ahmet. The ground electrode is place on a bone, such as the elbow. One of the signal electrodes is placed in the center of the muscle and the other is placed near the base/start of the muscle. In one of my videos you can see the emg electrodes on my arm. Best to test with an oscilloscope to see how different positions affects the signal. Hope this helps

@@MahdiDesigns Great, thanks. So did you wrote the whole code by yourself or did you implemented the one which I can find on Google?
@@sahiljagtap1958 I wrote it myself, it's really not that complex. Just very basic servo motor control
@@MahdiDesigns oh ok, thanks for the suggestion!
Can you share all the videos shown in 17:11 need it as soon as possible for assembly
Hey man, first of all, great work and thanks for sharing it. I'd like to work on something similar creating my own model, is there any chance you can send me your SLDPRT files to get started?
Hi Solidworks Files now available for download. Please see latest video
can you tell me how much cost it will take to complete the project
Hi, i printed your project for a high school robotics project, and i was just wondering how the 'tendon locking point' works, within the finger. Is it a separate piece, or just a certain way the finger was threaded? Thanks!
Hi, that's awesome, I would love to see a photo. I looped the "tendons" through the tip of each finger. There are two small holes which allow you to loop through. Best to loop multiple times so it doesn't slip, you could even use a drop of super glue to really make sure it doesn't slip
Hey! First of all awesome that you've built this arm. It looks awesome. I would like to ask you though.. Is this suitable for someone who has no underarm and wants to use this as an actual replacement, or is this more a part for a robot? I know that u could probably use it as a prosthetic, but I dont see those things amputees have on the insides of the arm to control the movements. How do you intergrate them into the design of this arm? Or do you know who explains this online? You would really help me out since I myself am born without my left underarm, and want to built this myself. Thanks for the video, it's really helpful!
Cheers!
You can use EMG inside the device or an external myo arm band. I guess that's the plan here.
Without an underarm would be more complex. Essentially the more that is missing the more complicated the prosthetic arm replacement is in terms of design & control. This model was just a prototype, it wasn't developed enough to be used in the real world. However, an amputee in theory could still control this prototype using electrical pads on nearby muscles. The United States Military does advanced research on prosthetic arms. Search DARPA Prosthesis. In the future the technology will continue to get better and hopefully become more affordable for the people that need it =)
bro w are working on the same sensor but we are getting the values over 600 when we give power to the senor
plz help
try reducing gain
first of all great work u did here, i am working on a similar project like this. i wanted to know how did u classified 6 different motion using only 2 emg sensor??
Mahdi Hussein ok thank you that helps alot
Just 4 motions using two emg sensors if I remember correctly. The fingers were all controlled together
For degrees of freedom, meaning mobility, he used the elbow as one, the wrist as another point, and then an additional one for each finger.
@@eduardochavez8820 very much false read the thesis for the correct answer
hello thank you so much for your stl files i was need only wrist rotation mechanisme for my hand thank you
hello mahdi thank you i find in your link
Hi Solidworks Files now available for download. Please see latest video
i am strated a concept model same like this but a Paralysis hand going to be present in side the prosthetic hand cover. can you tell me motion capture sensor you have used...
Hi, I didn't use any motion capture sensor. I used EMG muscle sensors to control the movement
i am currently in the stage of printing, logging and redesigning your prototype
would you want me to send you a log of my observations once it is completed as this should hopefully serve to improve the quality of your future projects?
Wow that's amazing! Great work. Sure that would be awesome. If you like I can also upload your files for others to access and learn from. My email address is mahdihussein.91@gmail.com
I have decided to make this project for my final year engineering, would you help me in this please
Hi, I want to ask you something, in your solidworks drawings, there is no connection between pinion and servo motor. How did you connect them?
I believe it was just a press fit onto the star shaped pinion, maybe also some glue or epoxy. It was just a prototype design
hi do you have the solidworks sketch. can you give me the link of the sketch in solidwork if becouse my universete bring me this hand for a virtual proyect but i don't have the measurements please help me
Hi Solidworks Files now available for download. Please see latest video
Hiii thanks a lot this video and your thesis was so helpful... Can you please share the code you used in this project?
Thank you! Sorry I no longer have the code. I would suggest researching how to control servo motors with Arduino
Great work, i am doing same subject right now. I need help on one issue related printing.Merely, i have printed all the parts except bicep Stl file . i have printed that part twice, but during printing it cracks .Would you please guide me related to that problem.
All parts that you have 3D printed were accurate??
Firstly, I was getting a crack during printing of bicep stl file. Fortunately, i solved that problem and now all the parts are accurately printed in their original form.
Hi Solidworks Files now available for download. Please see latest video
cool project i hope you can improve more light weight
Sir, please provide with the locking pin (screw) details used to join finger sections
Thank you sir
Just cut sections from a spool of 3D printer material
What a nice work! I'm from Brazil and for my graduation Thesis I will be doing something similar to your project! I'm really excited for it, but I have one question regarding the independent movement of the fingers. How can you control the fingers independetly, when you have only two EMG sensors attached to two muscles? Wouldn't just your biceps muscle control the thumb and the forearm muscle control the remaining fingers? Or do you regulate it depending on the signal power coming from the EMG sensors? Thank you very much and if you have some time, I would be happy to receive an answer from you. Cheers!
Hi Gabriel, did you control the fingers independetly? I want to develop a prostetic for a little boy. Thanks!
Hi, sorry for the late reply. The fingers I controlled all together at once so not independently. You could also incorporate signal power into control in different ways. Solidworks models uploaded now, see latest video
@@MahdiDesigns Thank you a lot!
hello you still have the code that you used for the prosthesis? I have to do a project and I need the code to do it,
if you could do me the favor
Hi, sorry I don't, I suggest learn about Arduino
Im a Mechanical Engineering student, I'd like to create a prothesis. What did you use for the control program?
I used a PIC microcontroller but i would suggest learning and using arduino
How would you suggest I get started with a project like this
@@kevinperera6129 If you have Solidworks (maybe you can access it at school) I would take some time to do some of the in built tutorials. When you have some basic skills start trying to model objects you find interesting. You can also buy am arduino (they are cheap) and look up youtube arduino tutorials. Just start small to develop basic skills. You could initially start by designing your own prosthetic finger and using a servo motor to control it. Good luck!
Im a freshman in highschool and im interested in starting a project like this! In the future I would like to be in bio medical engineer.my school has a 3d printer i can use. how can i get started?
I would start by learning a free CAD software like fusion 360. Arduino is also great for learning programming
assembly doc is exploded. i couldn't find configuration manager on solidworks 2018.
Can you make video step by step how to make that without 3D printer
Where to get the code from?
I want to make this in solidworks(as a project)
how can i do this with stl files?
someone please help
Hi Solidworks Files now available for download. Please see latest video
Bro i am a doctor. And i want to get involved with this. I want to start creating. So can i know where to start? And how about progressing from there after.
That's great. This is design engineering work. You could start learning CAD modelling (Fusion360 is a free program) and also electronics and software (arduino is a good place to start). Perhaps with your medical knowledge you could find some engineers/designers and collaborate
I need this cad sketch I can't make the payment process
What did you use to connect fingers with each other?
I used 3mm 3D printinf filament but you could use any kind of materiap rod
How do you connect the wire of the Horns? (Sorry for my englisch)
Small holes in the horns, loop the rope through and tie knot
Hello sir, it’s so inspiring to see your video. I’m also in university and my project is to build an adaptable prosthetic arm using 3D printer. I was wondering if you would mind to share your research paper with me cause I’m in my first year of engineering and really don’t know were to start.
Thank you for considering my DM
Hi Mahdi firstly it is very usefull video for me we have a group for final thesis and we want design prostethic arm like you but i have a question for about project How did you position emg sensors ? How can you determine points of arm? Thank you again have a good day
Thanks Ahmet. The ground electrode is place on a bone, such as the elbow. One of the signal electrodes is placed in the center of the muscle and the other is placed near the base/start of the muscle. In one of my videos you can see the emg electrodes on my arm. Best to test with an oscilloscope to see how different positions affects the signal. Hope this helps
@@MahdiDesigns Thanks a lot Mahdi
Brother could you tell me where or how I could get the digital files.
Can you access them through the link in the description?
