Thanks Subham. I don't have blueprints for this, but can share a lot of pictures I took during the build. If you reply with your email address I will share my Dropbox folder with you. Cheers :)
Hi Peter ! It's me again, thank you so much for the info on your 1st generation Arduino arm you have sent me, it has helped me learn A TON as I'm barely beginning to learn about the Arduino and how it works. It's been very influential for me to learn more and become a better maker. I'm also amazed to see this 2nd Generation arm shown, it looks so cool ! (Would be awesome to see it used as part of a Terminator replica) It's coming along very well now that you've added the rotating wrist movements, great to see that you're aiming for improvements ! Would you happen to have any info for this arm to send ? I would love to learn more about it and how it works (: Please upload your 3rd arm when it's complete, I'm very excited to see what changes you make ! Keep it up!
Thanks for your kind words Sanchees3! My apologies for the late reply - if you'd like more pictures of the build for this metal hand, let me know and I'll add your email address to the Dropbox folder. Cheers! Peter.
Hi Saul, I've just added you to my Dropbox folder containing a bunch of pictures and a different video of the metal hand. Hopefully this will show you a bit more about how it was built. The 3rd hand was going well, however I've been sidetracked with a 6 wheel drive Mars Rover that I'm building out of metal and 3D printed parts. I'll be uploading videos of it hopefully before Christmas. Anyway, good luck and enjoy! Peter.
Sir wonderful project :) i would like to know the load bearing capacity of the motors used in your project. In general the micro servos has a load bearing capacity of around 3kg how much weight can your prosthetic hand carry? Please do reply sir
Hi Vaishu, thanks for your kind words. The micro servo's I used don't have much of a load bearing capacity, therefore the hand can really only carry a heavy screwdriver. For heavier loads I would consider gearmotor of some kind, however once you use a gearmotor you need to have position feedback like an encoder along with housings, so it can get a bit messy. Cheers and good luck!
Hi sir, do you have a complete illustration of these? Perhaps a cad illustration? I wanna figure out how you connected the wrist to the arm.Your project will help a lot with our robotic arm. Thank you!
Hi Sydney. I have many pictures that would help you - just send me your email address and I will share my Dropbox folder with you that contains them all. I didn't use CAD for this hand, only trial and error and a lot of metal manipulation. Cheers! :)
+Afrah Farah Hi Afrah. There are 2 servos that operate the wrist, and yes they are hard to see in the video. The first servo is actually located on the long aluminium forearm section - you can see a black rectangular shape with what appears to be wires branching out from it near the orange bench clamp - this is the servo that rotates the hand. It is joined to an aluminium cylinder that houses the tendons, and the cylinder then connects directly to the wrist assembly. The second servo is built into the wrist assembly at the base of the hand - again you can see a black rectangular shape next to a shiny aluminium bracket - this is the servo that bends/flexes the hand up and down. It is anchored to the aluminium cylinder mentioned above. Hope this helps! :)
On the wooden version of the hand, the thumb swiveled on a screw, but how was the additional movement of the thumb achieved in this adaptation of the hand?
***** Hi Lucas, I used the same approach with the whole thumb assembly swiveling on a small bolt. I anchored the swivel tendon to the bottom section of the thumb assembly, then routed it back to the servo. The thumb opening/closing action had it's own tendon and servo, just like the wooden version. It's essentially the same, however this hand took a lot longer to make as I custom made nearly all the parts.
hello sir me again x) i was wondering if you could explain to me how exactly you got all five fingers to move? what power supply should i use or anything that i could consider , my version has movement but only 4 fingers with a 9v battery supply , thank you
Hi Cody, did you get a chance to have a look at my Dropbox folder - it contains a lot of information as well as the code regarding how all five digits move. What specific problem/s are you having with your project? Cheers, Peter.
hi im still unable to get 5 finger movement, your code is complex to my understanding , ide rly like to start out with an open and close sketch that allows 5 finger movement, im not sure what it could be, i have sufficient power also updated my ide i still dont get 5 finger movement xD
Hi Cody, it's worthwhile having a look at the resources available online - there are a lot around servo control. For what you want to do, it sounds like you just need to get 1 servo programmed and tested for 1 finger, then just copy that code for the remaining fingers. Good luck!
I have really enjoyed watching your robot hand progress. I saw in your first video that you mentioned that you're currently on the third generation. have you got any videos of the third generation hand? I've got lots of questions - why two servos for the thumb? What are you currently using for your finger hinges? These servos look smaller. What servos are you currently using?
Hi Nick, thanks for the kind words. Yes, I'm currently working on version 3 at the moment - still have a lot to do, but it's coming along nicely. As soon as it's ready, I'll post a new video! Ok, two servos for the thumb - one to swing the thumb assembly up so it faces the fingers, the other to then close the thumb in flexion. This allows the 4 fingers and thumb to close together in a human-like grip. I used spring-loaded wall anchors for the knuckles as they self close, although as you can see in the video they tend to jam up a bit. The servos are micro-servos that are used in RC Helicopters - they have lots of torque and are relatively inexpensive. Version 3 does away with servos altogether, using motors and encoders - something that's taking a little while to get working. :)
Peter Ohlmus Are you switching to DC motors so that you can wind the lines rather than pulling them with servo horns, to reduce the physical space used by the horns, or some other reason? The wall anchors is a great idea. I wondered how you were getting them to return to position.
Hi jhunphillip123, if you reply to this comment with your email address, I'll give you access to the dropbox folder containing a lot of details, pictures and code. Cheers! :)

hi i think this is fantastic would you consider a full length tutorial? im building a robotic hand as well with arduino and need a little help in doing so xD
Thanks Cody. I would've considered it a few years ago when I made the hand but I've moved onto other projects. If you're interested, I can share my dropbox folder with you - it contains images and information about the build of the hand - just reply to this comment with your email address. :)
Beautiful
Good work

Yes, I'm using the DC motors in a completely different arrangement to save space and for more torque. All actuators will be contained within the palm.
Sir,I'm interested with the design, is there any way for me to see the mechanics and coding for this hand? like the design and everything?

What kind of servo motor this?
Just regular, cheap micro servos :)
@@PeterOhlmus it is 180 degree rotating servo or 360 degree rotating servo motor?
@@PeterOhlmus how many degrees servo motor what do rotate for this project?
@@saravanakumar2765 standard 180 degrees is fine.

You realize, this is the first step towards Judgement Day.
sir,thank you if you design a robot leg pls post

Great job kid.
i want that code is it possible
