I did a few hands a few years ago (and actually should be working on one now...). What I ended up learning from the experience was that standard robot design approaches, and technologies, are quite limiting. For example hinges with axles through them take up too much space, servos being really awkwardly shaped etc. I think the way to crack it is to combine soft robotic actuators, bones which slide past each other, and elastic and tensile elements. Have you looked at tensegrity inspired models of the body? It helps to see how the body can be broken into different elements beyond the typical rigid elements+hinges approach. A hand that is underactuated but held together with elastic and tensile elements can wrap itself around an object it wants to grasp. Have a look at the hand design by Zhe Xu.

I made them mostly for robotic purposes as I want to build a whole humanoid robot at some point. There was some interest in prosthetics and I chatted with Openbionics back when they started. I also contributed to what became the Enable hand. Since then life got in the way, but also I've been looking at learning how biology approaches these problems and the pros/cons of biology vs standard engineering. There's a lot of cool research going on in soft robotics and programmable matter which could help us approach the design in a more organic way. There's a lot of ways that biology has made its mechanics optimised for it's role. I mentioned the gripping in the previous message, but there's stuff like passive dynamic walking, which helps explain why humans are much more efficient at walking than a robot like Asimo.

I've had a quick look at your videos, there's some fascinating stuff there particularly with your tensegrity spine, is that something you're still working on? I did this hand as a university project so there was a lot to cram into the year, but after seeing that project by Zhe Xu with the little crocheted joint capsules I've been really interested in that sort of thing. I'd like to be working on a new design now but as you say life is getting in the way haha. Let me know if there's somewhere I can follow your progress on your humanoid robot.

Good evening Will, I wanted to point out that it is precisely the discriminant between convergence and divergence of the metacarpal bones that is the biggest problem in designing and creating an artificial hand. The fact that you have correctly observed what is the natural mobility of the bones of the metacarpal, their semi-independence of movement and the different ability to articulate the last two fingers of the hand. All factors that must be calculated not only for size but also for exact structuring. The more they are similar to human bones, the greater the possibility that the limb responds naturally to its use. Congratulations, a greeting from a cybernetic lover.

Instead of bolting everything together, we tried to hold everything together with an elastic mesh.

I still have a few kilometers of flexinol in my basement if you're (or anyone's) interested haha.

Will, one option you may want to explore is sand casting using your 3d printed parts to create aluminum versions of them. This is a very impressive design and you could reinforce those areas by 3d printing then pattern casting them. Lost form casting I believe is the correct term. here is a wiki link en.wikipedia.org/wiki/Pattern_(casting) if you're interested. Excellent job on this gives me hope in the future that there are still bright minds coming up nowadays I have been a mechanical designer going on 20 plus years now and you have a rare talent from my experience. Keep it up and the sky's the limit.
@talatmahmood57875 жыл бұрын
I made something similar for my coursework in college and I used a similar approach of using servos and pulleys. But a big difference is my project had minimal set up and was controlled a different way. First of all I utilised the 3D printers ability to build supports, so in between my hinges the 3D printer had built supports and these could be "snapped" so that the hinge was now free to move. So I printed the whole hand except for the palm piece as a single print. The palm piece was printed separately so that I could easily thread the wires through the fingers and then later snap the palm in place. I printed the forearm like this also, so I could snap all of the parts together with no use for screws. I had only a basic open and close motion set up using a Myoware sensor so that when the user tensed their arm it would close the fingers. There were some pretty big issues with the design which I would change if I ever redesigned it along with the aesthetics, like yours looks a lot better than mine. Amazing work by the way, I really like the approach that you have taken. Keep up the good work!!!

Another thing I think that force /stress and torque of a human hand & fingers can generate Should be same for the robotic hand. Another thing I want to mention is that few years back I saw a video where all the cables at middle of the hand they were using a wooden special shape object to control all types of grips. So in that case my plan is to use lesser number of actuator to complete the project. Definitely what you have done so far is unbelievable work. I am very happy to see your this video.

You should consider using something like a flexible filament for the palm area with maybe strips of spring steel strategically placed to replicate the human palms movement. You also need to be careful to keep the lengths of the cable runs the same length, even if you actuate other things like the wrist. The cables should always be pretty taut. When designing linkages don't think about how the human body does it, you can't really do it that way because muscles are different than motors. Focus on the end resultant movemen. Overall the goal should be for design as simple and stiff as possible while still meeting your goals for realistic movement.

I'm not certain that this will be helpful, however for the finger curling I imagine you could use something along the lines of the turning mechanism in a longboard. I've seen some that use rather wonky looking angled plates, so what I'm imaging here is an angled slide channel in which the finger mech mounts. Additionally I would recommend adding a bit of elasticity to the 'tendons' with either actual elastic cores or spring and slack configs, I've seen this provide torque control and safety functionality with limited complexity on some hand models. Alternatively you could monitor the motor current and attempt to match it to the torque curves of the servos, but that's a touch complex for early prototypes imo. This very well may not be particularly important with the current mock-up, however down the line if you transition to more powerful motors/stronger materials you run the risk of either breaking the hand, the tendon's, or whatever the subject may be holding without proper limiting of some sort. Almost forgot: personally I f***ng hate traditional hobby servos, so I'd also suggest in any final versions upgrading to brushless motors with planetary gear sets and optical encoders, the hobby servos have very little power and typically use potentiometer as encoders which hurt reliability. Planetary gear sets are actually easier to design WITHOUT back-drivability than with, which means you don't need to continuously pump current into your motors to keep the fingers taught. I'd suggest using low profile bldcs, which may even make the lower arm bit more compact. Switching from the brushed motors should also boost efficiency a touch, not bad for something of this sort. Very well done tho, I for one am impressed by the level of artistry you put into it, beyond the engineering it is truly a work of art.
