Do you have the printer files for yourself or could I use them my little brothers Arm and leg is weak and I would want to use this exoskeleton stuff to help him regain some muscle and be able to use his limbs normally
In this video there is no augmentation, that's why it's called "wearability test", in order to check if there is discomfort or not. All the other updates with the addition of preloads and detailed log of the project are on my IG if you are interested
@@nozzle_torino Well hell, I can answer your question without even trying it on. If it's just a wearable test, then I can guarantee that it ain't comfy. Here's what I recommend: Line the interior surfaces with foam rubber... problem solved, question answered. When I get mine built, I'll show it to you and demonstrate that function followed form. And I ain't got no metal dep 3D printer, but I've still got lots of dumpster crutches!
@@nozzle_torino Just one more curiosity and I'eave you alone. As I asked before, what exactly is the mechanism in the upper body for power augmentation? It's gonna be augmented, yeah? It looks totally bad ass, and it looks like you've demonstrated 'wearability, so are you gonna print one with metal dep next? And one more thing .. How exactly do you achieve a 30% - 40% power increase? I'm gonna use torsion springs, ratchet springs, extension springs, and spear gun rubber, all installed at strategic locations.
@@kaxtorplose yes there will be, this one in the video was a very first version of the exo. The printed pieces are hollow so that elastic bands van pass through it and act in parallel to the muscles. Depending on the band added the supported movement can be flexion or extension. In any case then I switched to the lastest version which is much more simplified in order to save printing materials and weight. Regarding the 20/30% that's achieve with proper preload of the springs/bungee so that they create a certain torque about the joints (based on the torque our joint already produces for normal actions). At the moment of course I don't achieve that % because of structural limits of the material I'm using but that's all I can do at the moment not having a workshop of the funds to make it out of metal. Hopefully later on things will change
Part 1 If you don't mind sacrificing some of the intricacies of your printed parts and instead focus on much simpler shapes which still function exactly like your printed pieces and would still provide the exact same functionally for a much simpler form, you can bypass the 3D printer altogether and just build it as a functional exosuit made out of aluminum struts sourced from aluminum crutches. I live in a college town, near the campus of UNT - and at the end of every semester, t's time to go dumpster diving for aluminum crutches that athletes use when they get injured. After they've healed up at the end of the semester and it's time to go live with mommy and daddy for the summer break again, I can find several pairs of high quality aluminum crutches dumpster diving for crutches in order to source my FREE ALUMINUM! Geez, ain't jocks and meat heads retarded? Dumpster diving for aluminum crutches in Denton, Texas is a consistent event + one which I refer toa as Crutch Dumpster Season! I've sourced at least a dozen pairs of crutches in this manner over the past six years, but unfortunately most useable aluminum goes to waste, as I use them up creating prototypes of different types of bionic boots. I also lose a lot of aluminum by prototyping lower body unpowered exosuits.... mostly by using hinge shaped torsion springs, mounted on a comfortable, sturdy material, with the spring mechanism fitted at the back of the knee to provide a MAJOR increase in lower body performance..., and like my actual jumping boots, this rear mounted torsion spring is something I can build for practically nothing! I'd still probably want to build a structure which can be strapped to the thigh and calf, because building extra support into your bionic machines is always a no brainer. As for my attempt at building a passive upper body exosuit, I'm still figuring out the design. I've got all of the main mechanisms designed, and support structures worked until my sketches (it's WAY EASIER for me to sketch out DIY builds, as oppressed to using Blender and/ot CAD, and/or 3D Studio Max - the main software I was trained on, which is pretty ironic, considering that I have an AA in Computer Animation!

What they said was, 'THROUGH THE FUCKING STRATOSPHERE!" NOT "Through the roof..." THROUGH THE FUCKING STRATOSPHERE, AND GETTING DANGEROUSLY CLOSE TO THE KARMAN LINE!" Which is a proposed conventional boundary between Earth's atmosphere and outer space set by the international record-keeping body..." YADA YADA YADA BLAH BLAH BLAH. I let out a cavernous yawn. "Yeah, I know what the Kármán line is..." Suddenly I was filled with renewed vigor! "Say, do you guys have a Space Force?" The two officers turned away from me with their heads touching. They were whispering. Finally, after about 5 minutes, they turned back around to face me. First Officer - "I'm sorry, but there's no Space Force -" The other officer, the uh... Subordinate Officer interrupted his Superior. Subordinate Officer - 'Yet!" The Ranking Officer looked as of he'd take gray pleasure in throwing the other one with his bare hands. I was THIS CLOSE to telling them that the Start Wars Prequels were gonna SUUUUUUCK!" But I managed to hold that one in. First Officer - "The point is, there's no Space Force RIGHT NOW, and there are no plans for one." Subordinate Officer - "Well, that's the biggest lie you've upchucked ever since you failed the Astronaut Corp selection process." Before these two proceeded to engage in nuclear combat, toe to toe, o Brooke the tension. "I wanna be an Astronaut in the Space Force!

Subordinate Officer - "(Whispering) He's not serious, is he?!" Superior Officer - I'm afraid so. Here's as fruity as a nutcake, unfortunately. It's our task to forcibly TAKE the SMARTEST MAN ALIVE and put him on a submarine. Obviously the safest place for long term storage..." The Superior Officer turned back to me. Superior Officer - "Plus, you actually know that neutrons decay after about 30 minutes, unless..." I was feeling randy. "Unless they're held together in the atomic nucleus, bound to protons by the string nuclear force, but in the presence of a moderating material like water, or BORON, those neutrons obtain critical mass and a chain reaction begins, first releasing a blue..."

Superior Officer -"God help us all..." That's what the recruiter said, I swear! "God help us all ifwe run out of fissionable material in 30 years instead of 50!" Heh. This guy came to my house PREPARED! "So hopefully you can understand - what am I saying? Of course you understand! After all, you ARE one potential recruit amongst a mere handful of recruits who have the smarts, the talent, and the skills - plus the scarce screwdriver skill for when you're playing with a ball of plutonium inside a boron shell, just to see how much stray neutron radiation can be safely be extracted from a 15 pound ball of plutonium..." I'd had enough of this guy. "That would be Louis Slotin, sir, and the fact that he happens to be dead at this very moment is because the damn klutz dropped the screwdriver, which had the effect of sealing the boron moderator,, generating gay neutrons and also a CRITICAL MASS, and giving poor Louis a deadly dose. He didn't last but a couple of weeks after that the entire ball of plutonium sent a deadly dose of fast neutron through the plutonium, through the boron shell, and straight through Louis. It was obvious that they wanted me trained up post haste on the nuclear reactors installed in aircraft carriers and submarines... And I almost calved and joined the Navy, until I began hearing stories of suicides, exclusively aboard Boomers and Wolf Pack Attack Subs Back to the exosuit. My design will require a waist mounted brace to act as a load bearing device with two, maybe four pieces of aluminum tubing for housing the spear gun rubber running through the direct center of the back, a few torsion/locking ratchet springs mounted at each elbow, and possibly a block and tackle mechanism for distributing the spray gun rubber onto the shoulder mechanism for easy transfer of forces at virtually any angle, more torsion springs for my back knee powered device, plus two leg armatures... NOT THAT I FEEL AS THOUGH I'LL NEED THEM, BECAUSE INJURING SERIOUSLY MY LEG OR MY KNEE IS SUCH A REMOTE POSSIBILITY, I CAN CONFIDENTLY SAY - "THAT WON'T EVER HAPPEN!" But by far I've fucked up the most crutch aluminum by hammering the cylindrical struts too hard with a hammer on order to flatten them. I've ruined struts with cracks that appear at the flattened ends, and of course the Bane of the Self-Taught Mechanical Engineer, just flat out fucking up the build because my design turned out not to be CRAP. So the moral of the story is this: If you can't afford a metal deposition printer, you can spend about $200.00 U.S. on about four pairs of 300 pound rated aircraft grade aluminum alloy crutches at CVS, but in actuality you can get them at practically any pharmacy. You could probably get them for the least amount of U.S. Dollars, UK Pounds, Euros of the European Union, Deutch Marks, Turkish Lira, Russian Rubles (LOL), a U.S. Silver Certificate, that hyperinflationated crap in Venezuela that they keep printing in order to finance this and that (could somebody please tell Venezuela, that's not how you fix hyperinflation? By printing so much money that every citizen is an instant billionaire when they get paid at the Coca Cola bottling plant? Anyway, by purchasing aluminum crutches (or by finding them in the dumpster) you can save money that you'd use for attempting to fashion truly complex parts with CAD and printing parts using a 3D printer that uses PLA, which is worth its' sight in gold, apparently. See here, now. I've been watching your channel fairly non-stop since I discovered it yesterday because and every time there's a new video (especially the 'wearability' video), I'll discover yet ANOTHER part which can be simplified to extreme levels, while retaining the original purpose of the party without sacrificing a single erg of the practical usage as demonstrated by your 3D printed parts which you'll either wind up throwing away, out possibly recycling the PLA (can they do that yet?) probably also sell them for a lot less at the Walmart pharmacy. Working with Crutch sourced aluminum s a lot of work, because you'll need to hammer the shit out of long pieces of aluminum tubing in order to flatten them so the struts are closer to 1/8th of an inch thick, which is the thickness you want off your buying bulk aluminum plate. If you Google "aluminum plate" or "aluminum tubes", your can find bulk aluminum 1/8" plate, around 12"X24" for less than a hundred bucks. If you shop around, you can find metal supplies which source their aluminum for even better prices. And: 1601 alloy aircraft grade aluminum is what you'll want. As for your force multipliers, you can order any length of spear gun rubber and cut it to the correct length in order to slide through the tubing on the back and onto a block and tackle or you can design an all-direction freely swiveling U-joint which can give complete freedom of movement at the shoulder, then attaching the spear gun rubber to a study point, using your back as the main load bearing mechanism. The 'muscle'for the forarms uses a ratchet spring at the elbow, and an expansion spring mounted at the video asking a diagonal which swivels freely at each of the four corners. It's the 'parallelogram' structure which uses an extension spring mounted from one corner to an opposite corner which provides the power for this unpowered upper body suit I'm gonna start building at some point this year. First I'll need to finish my latest pair of Bionic Boots with all off the kinks worked out.

NOT THAT I FEEL AS THOUGH I'LL NEED THEM, BECAUSE INJURING SERIOUSLY MY LEG OR MY KNEE IS SUCH A REMOTE POSSIBILITY, I CAN CONFIDENTLY SAY -

But by far I've fucked up the most crutch aluminum by hammering the cylindrical struts too hard with a hammer on order to flatten them. I've ruined struts with cracks that appear at the flattened ends, and of course the Bane of the Self-Taught Mechanical Engineer, just flat out fucking up the build because my design turned out not to be CRAP.
So the moral of the story is this:
If you can't afford a metal deposition printer, you can spend about $200.00 U.S. on about four pairs of 300 pound rated aircraft grade aluminum alloy crutches at CVS, but in actuality you can get them at practically any pharmacy. You could probably get them for the least amount of U.S. Dollars, UK Pounds, Euros of the European Union, Deutch Marks, Turkish Lira, Russian Rubles (LOL), a U.S. Silver Certificate, that hyperinflationated crap in Venezuela that they keep printing in order to finance this and that (could somebody please tell Venezuela, that's not how you fix hyperinflation? By printing so much money that every citizen is an instant billionaire when they get paid at the Coca Cola bottling plant?
Anyway, by purchasing aluminum crutches (or by finding them in the dumpster) you can save money that you'd use for attempting to fashion truly complex parts with CAD and printing parts using a 3D printer that uses PLA, which is worth its' sight in gold, apparently.
See here, now. I've been watching your channel fairly non-stop since I discovered it yesterday because and every time there's a new video (especially the 'wearability' video), I'll discover yet ANOTHER part which can be simplified to extreme levels, while retaining the original purpose of the party without sacrificing a single erg of the practical usage as demonstrated by your 3D printed parts which you'll either wind up throwing away, out possibly recycling the PLA (can they do that yet?) probably also sell them for a lot less at the Walmart pharmacy.
Working with Crutch sourced aluminum s a lot of work, because you'll need to hammer the shit out of long pieces of aluminum tubing in order to flatten them so the struts are closer to 1/8th of an inch thick, which is the thickness you want off your buying bulk aluminum plate.

As for your force multipliers, you can order any length of spear gun rubber and cut it to the correct length in order to slide through the tubing on the back and onto a block and tackle or you can design an all-direction freely swiveling U-joint which can give complete freedom of movement at the shoulder, then attaching the spear gun rubber to a study point, using your back as the main load bearing mechanism.
