Dude you are making history with your designs, keep it going. Also i am working in the same field alone with a partner, just two med students, and we have made some incredible development in artifical muscles that are realiable and are really strong. Wish in the future maybe we could work together in a project.

Neat! Are you using those ones made from supercoiled plastic filament, like fishing line? The simplicity of design, yet broad capabilities are amazing.

I worked on a similar design back in the 90s when I was just starting High School. I was 15yrs old. I started designing prosthetic limbs because I kept having recurring dreams that I lost a limb. Some times it was my hand, some times my hole arm, sometimes my foot or leg. I still fiddle with the spect, but and focusing on feet and legs now. Thanks for the inspiration.

:O Exciting to see you designing a servo. It's been rattling around my head for years too, ever since trying to squeeze as many servos into a small space as possible, eventually you just think... i bet i could do this smaller by specialising the types of servos. I figure if i'm making servos to actuate pulleys anyway, why not ditch the gears and just *use the pulleys for gearing.* ;) You inevitably get into issues of the pulley/spool bend radius being so small it damages the cable, so i'm using flat ribbon instead of cable.

Once your hand redesign is complete and functioning, would be very cool to see this CNC machined in hard metal, 7075? Titanium? Would be a literal terminator hand.
@magnumopus90584 жыл бұрын
Calculating for a round bar of 7075 with 10 mm diameterr 50 mm length it would weigh 11,09 grams, after machining it would drop to about 8 grams i suppose so i guess its doable

@davidthorp014 жыл бұрын
Man I can’t wait for that, do you KNOW how creative I could get if I could just assemble my ideas, instead of relying on machining or other limitations? Plus it’d be on hand and I wouldn’t need to wait several days if I had to special order something. If they sell the servos themselves, surely we could either see if they manufacture the gears on their own or what company supplies them? If you don’t have to order the servo as is, we could restructure the design as needed without worrying about a bunch of plastic hulls, discarded wiring, or motherboards How do current Metal 3D printers go about working? Like is it liquid hot metal in templates or something like a molding process?

Okay so.... just found a few videos about creating artificial muscles ... No not those hydraulic or pneumatic ones. The ones made from supercoiled plastic filament, like fishing line. The actuation works on heating the coils. When heated they contract, also they spring on their own accord, to an extent. I'm really looking forward to what you're going to build with these servos but I thought you might want to take a look at it as an alternative for the cables you're going to use or even as an actuator for really tiny muscle groups needed in the fingers. At the very least it may be something to work as an attention grabber for the video series.

You know, this design process is absolutely brilliant. I hope it turns out as well as you’re hoping, since this could stand to help move forward research in limb replacement (if only to actually have a decent hand design!). This could also serve in all kinds of other robotics to spur some ideas into various creative servo redesign. I do wonder however, if this could be possible to apply to the exterior of a hand through similar design. I’m thinking along the lines of Arthritic patients who might have trouble with their hands, but still have them. If this could be possible; needless to say we would need to further miniaturize the servos while still keeping equipment integrity and range of motion. It would be difficult but not impossible. This way; should joint decomposition or bone damage impair movement, we could find a means of re-aligning the hand for an almost odd form of physical therapy (if only to keep muscle degradation low). It’s only an idea, but I’d need a hand figuring out how best to make the gauntlet without being bulky, since it would need to both act as an exo-skeleton in its own right AND be as gentle as humanly possible to the person wearing it, while keeping weight low. From how you’ve got your design, it fills my head with ideas. Ideas I’d need to figure out how to make. I’m currently getting a masters; just not in engineering or robotics, although I’m considering just picking it up because I want to understand it. History is my passion, but learning broadly is a part of said passion. A curious mind to the end. At any rate, this idea is simply brilliant, and I can’t applaud the level of creativity put into the design enough.

Great work, Will. Hey, I am artist, and find drawing hands a real pleasure and challenge. Try drawing them in different poses, as you continue to refine your design process. I feel that the form/factor really comes through in this, and you end up with a real, sorry, feel for the reasoning of the placement of the parts.

Hey Will, wouldn't it be easier, less "clunky" and I guess structurally stronger to print 1 part for all those 4 servos. Those parts are not moving (or move only slightly) on a human hand anyway. I guess that would make you to be able to use less "walls" and gain more place for servo gears, thus also making the whole thing thinner. I hope my English is understandable. lol :)
