Real Iron Man Prototype Arm, Powered Exoskeleton

[@hacksmith]

Very cool! You might want to move the mounting points of the pneumatic muscles further away from the elbow -- you're losing a lot of potential strength and power because of the lever arm!

[@JamesiosoHo]

the Hacksmith Thanks for the suggestion. I tried to keep the geometry somewhat similar to that of a human arm to get more range of motion.

[@tankolad]

Jamesioso Ho Just use a pulley. Simple as ;)

[@Yzyenthusiast]

If you made the muscles both ways .both pneumatic and hydraulic.it could lift more

[@maddenmadness]

the Hacksmith Is this basically what your nano suit arms are going to be like

[@hacksmith]

Hack Masters Similar but for my nanosuit it's just going to augment my natural skeleton -- dangerous yes, but I'm only planning on doubling my natural strength... so the way I see it, if I were to workout reaaaaaaaaally hard, I could do that normally (maybe) and that would just mean I'd get bigger muscles, so by that logic, my bones should be able to take it ;-)

I dunno if anyone has mentioned it, but for the love of god don't forget a hardware limiter on the joint angles. they demonstrated pretty well in iron man what happens when an armour bends more than the person inside it :P (nice job btw)

[@aurelianspodarec2629]

The weight is on your feet though. Anywas, you need to make a construction that can lift 400kg with one arm like if it was 1kg, and then throw it like a baseball with the force to penetrate a house.

Yes. There is a latex tube inside that inflates.

[@eduardomayoral254]

ill be shure to credit you for the design idea im creating a full body exo skeleton ☺✌

[@northmustang5220]

+Jamesioso Ho || I don't mean to pick at your creation, but the whole idea of an exoskeleton is to almost entirely if not entirely take, in this case, the weight of the object being lifted, off of the operator; So it really isn't completing its task when you have to use any of your strength to hold it up... Basically all it's doing is making it easier on your arm. Again, not picking, just giving you, or anyone else reading, something to think about when making an exoskeleton.

[@JamesiosoHo]

I agree completely. For a exoskeleton to be truly functional, one must transfer the weight to the ground via an entire suit. I merely created an arm for the kicks of it and to learn about the operation. Thanks for your insight tho. :)

[@IraQNid]

You'll aggravate your carpal tunnel the way that metal band pinches across your wrist like that. I see that as a serious design flaw. The other flaws that I see are the use of unprotected air lines. Should anything happen to one or more of those I would expect the related controlled surface or mechanism to suddenly fail. Which could be catastrophic if being used to lift heavy objects.

[@FrankLopezx]

+IraQ Nid YUP! one of those air muscles pop its a wrap for that body limb not to mention the weight drop of the load all on your body at once, def going to strand some tendons or or bone issues specially if your own body cant deal with the sudden load that you will be forced to "catch in mid air" if i was him i will work on a robotic dummy to be the test subject and use pressure sensors/force sensors on the dummy and monitor the info on the terminal window

[@pixelbrickbuilder768]

@@FrankLopezx im not knowledgeable on this stuff but could you build a whole suit so that weight supports itself? There would have to be a way to put in a fail safe device too. I wanna build one of these one day and just wanna learn more about that

[@pixelbrickbuilder768]

@@FrankLopezx what if you had sone kind of cable attatched that connects the two pices, and locks if it is suddenly pulled on know what i mean (sorry for my lack of knowledge on the subject) like my dog leash is that way or even a seatbelt, when you pull hard( or it snaps and the system fails) the wire catches it and its the same as before except you cant control it and it gives you time to set the object down and fix it

[@carlhass13]

I have an idea. Is it possible to, instead of steel or aluminium, construct the frame using carbon fibre?

[@yeah9071]

The hardware isn't the challange of the exoskeleton, anyone can do that. The challange is the software for it to work in coordination with the human.

[@JamesiosoHo]

you are correct.

[@sanlistonmadzima]

+Jamesioso Ho No He is incorrect. Making the software is difficult, sure, but no more difficult than taking initiative and actually building a working model to prove the concept, like you have done. Don't let bitter people on the internet discredit you of your hard work, Jmaesioso Ho.

[@shawnbroz8212]

+waytoomanyllamas u dont understand both of them ,hahaha , thats not bit, its truth

[@Rubysh88]

+waytoomanyllamas dude, building robots is relatively easy, making the software that will control it will always be the hardest part, it requires allot of calibration, inverse kinetics maths, the process of input data like getting information from sensors and know what's happening, etc. Really, the hardware seems harder because it's usually the only thing people see, but anyone with some electronics and microprocessor programing (e.g arduino) knowledge can build a robot, the limit is in the budget... and software. Programming an conscious A.I would be much bigger and harder step than building one of those huge robots from pacific rim.

[@sanlistonmadzima]

Ruben Fernandes Maybe you guys are right. I have only recently started programming so maybe I am overlooking the challenges that may be faced to build the required software to operate the exoskeleton.

[@EamonOBrien3]

this is awesome man! i'm working on a similar project and it would be fantastic if you could make a video explaining more about how you made it. I'm really curious about those air muscles.

[@DKSful]

Im doing a similar thing for my project, do you think a digital mini compressor used for inflating car tyres would also work?

[@Rubysh88]

next step, add either muscle sensors or pressure sensors on the inside "walls" so it can detect your arm pressing and move with it.

[@FrankLopezx]

+Ruben Fernandes what your referring to is called electromiography

[@Rubysh88]

+Frank Lopez yeah , even tho i personally like more the pressure alternative because you have to add electrodes, sometimes with gel, on the skin and its kinda annoying and messy every time you want to use it. With a precise pressure sensitive inner wall, you could just get inside the "armour" and use it even with clothing, it would for detect that the user is trying to move his arm (or anything else) because it would press the inner wall. For example, the processor would know that the user is raising his feet when the soles pressure decreases and the knee sensor detects an increase in pressure. Of course, we would have to program all possible sensor combinations.

[@huntersihelp]

+Ruben Fernandes that's what I was thinking. If I build one I want to eventually put pressure sensors in it. It seems like the smartest way to go about it.

[@FrankLopezx]

Ruben Fernandes yah you dont say lol but yes your logic is sound, i should take no more then 15 20 mins copy and pasting most functions and variables, luck with the debugging tho lol RIP

+Robert Cornelius Wouldn't that be nice? Lol

[@bhanuprakashpadmashali4298]

You can make the muscles yourself for cheap

[@BrookNBones]

Not being critical at all. It's a good design, but I'd step away from pneumatics and move towards hydraulics instead. I believe you'd get more force behind your bladders you are using for muscle contractions. You might need to change your lines to a braided line or one made for hydrolic systems when you move to higher pressures, but at low pressures the bladders and lines you have now should be fine and be able to perform better than pneumatic systems as liquids don't compress yet air does.

[@BektostheBlackBlade]

I agree. If this is for minor workloads then that's great but for heavy workloads (extreme example: 1 ton of concrete) then hydraulics are the way to go.

[@xilw3r]

more force yes, but hydraulics is messy, heavier, is more complicated. I was thinking high reduction planetary gears powered by small bldc motors in tandem. On the other hand pneumatics can also yield a pretty nice suit if you can find a portable pump putting out a decent pressure. In the future Im hoping for muscle imitation polymers which change shape due to electric field strength.

[@BektostheBlackBlade]

Hydraulics are messy if not properly sealed. And yes they WILL ALWAYS leak, no getting around that. But I'm not familiar with planetary gears or the muscle imitation polymers. I'll need to look into those.

[@BrookNBones]

I've no experience with planetary gears, other than what I've seen on KZbin. In each of those cases they failed because the user tried to get by with plastic 3D printed items to move or apply force to an object that weighed more than the gears could handle. Or they were using home made cast gears that they built themselves after making a 3D printed model as an example. They failed just as the printed versions did because they weren't using a forged item that was tempered for strength. Though I believe they would be to heavy and unyielding to the user. That's just my opinion though. Like I said I have no experience with them.

[@BrookNBones]

***** My only concern with air, while I know it's faster, and can with proper equipment be powerful, is it's not possible to get that power out of such small equipment. Sure, air bags lift train cars and buildings. But those are huge bags that work off of both volume and pressure, sometimes just volume. A small hydraulic system could do speed, and power without a lot of mess and cleanup if everything was housed and connected correctly.

[@Haziqisgoodname]

Good Design! If I might ask.. What is your justification In using air pressure as the base of your design?

[@Doc_89]

Very impressive, now use the hose system but switch out the pneumatics and instead use hydromatics. There should be an increase in power output since fluids dont compress, but there is the added risk of breakage and malfunction if you cant regulate the pressure though.

[@JamesiosoHo]

I will try that. All I need is to compress the fluid with air in a sperate container.

[@EvilMastermind]

I wonder why none of these people add a button to the ring by their wrist so when the user moves their arm up or down it actually starts up the suit while the user has the button pressed.

[@JamesiosoHo]

because if you hold something in your hand, the button would be pressed and the suit wouldn't hold the weight...

[@ashleycompton6761]

[@richie6799]

the hacksmith made something soo much more impressive

[@TheAwesomeBubs]

Tjis is sick james

[@waynefilkins8394]

That's kinda cool but air muscles aren't the way to go. You have to wear an air tank or w/e on your back and they are super bulky yet have a lack of range of motion. It looks like you somewhat fixed the ROM problem by attaching it further down the forearm, which was pretty smart, not sure if that is enough for real-world activities though. If you were moving super heavy stuff you would be quite limited and all that strain would go onto your muscles when you weren't in specific positions. With all that said, this looks really cool and you made it more compact than I have seen before. This is way better than the hacksmith guy's attempt at it.

[@vegastandalone7762]

14-17 kg...this is weight that most of the people can lift with one hand. But it is good start and you always can make it better.

[@sonithakurani1523]

U could also use small pulleys in your arm

[@robertperry8132]

looks like that bottem beam that connects the lower part of the bicep support is digging into your arm when you have it flexed you should do a curved connection that way It wont cut your arm off if the thing messes up. but idk I didnt make one Ill have to make my own and get back to ya

[@JamesiosoHo]

That is true. It does hurt a bit when flexed. Thanks for the suggestion, version 2 will not have that problem. :)

[@robertperry8132]

hehe thx. I never made something that versitile but I do think about being comfortable. Ive been working on prototype exoskelintons for a story I made and plan on turning in a film once I get a decent amount of money in bank but I got alot of mechanisms planned out and it offers mobility and comfort along with and additional rig for armor plating to be attached protecting vital functions and for operators organs your nanosuit design basically simplifies it but it more losly resembles looks like that guy that was lifting weights with his version also maybe I need to perfect my designs Cause Im kinda not too satisfied. then again I decided to throw them out one day not thinking that I needed them. but I memorized my work i put alot of thought into it

If u made an entire suit u would have to create a system to counter the weight cause here in ur video ur body is being used as the fulcrum so a suit would have to counter the weight distribution and momentum and why not make the wrist and hands fingers etc ull have to scale down ur framing hinges etc but can be done with a lot of work

[@williamhan5567]

Thats really good

[@austinalvarez3124]

im not 100 percent positive but if you added a wrist with air muscles it might take a little weight off the biceps and you could lift more

[@12101DyM]

In the end it can only lift as much as your back and legs can support, using those bladders to lift is a clever idea. I have questions Are they full of air or fluid? Where is the compressor? How much pressure does it take to lift a certain mass? Do you have any plans to create a back brace so you won't be limited by the strength of your abdomen?

[@Guds777]

I would rather use hydraulic system. More power density. Air can be bit bulky and loud. Closed loop hydraulic system can be quite effective.

[@multimargejta123]

add forearm muscles, for more range of motion

[@parullakhani7261]

[@kevinj4812]

the metal you used is a bit soft. i noticed it looked like it was bending when you lifted the air compressor. You could get very similar results if you used Linear Actuators (uses electricity). It would also be a LOT lighter (wouldn't need to carry the air compressor with you). Try using a high performance plastic like PEEK. Used the stuff in a few turbine projects on my large 3d printer (it's 6.5 cubic feet build area). I'm quite interested in taking your arm to the next level and applying it to a more full functioning exoskeleton.

[@JamesiosoHo]

The linear actuators on the market today are expensive and quite slow. The air muscles used in this project are less than 40¢ a piece.

[@kevinj4812]

Jamesioso Ho the actuators i found that were very responsive were Solenoid type actuators with HAL sensors in them (to send back positional data to the MCU). I forgot which company makes them, but i got a few samples from them about 6 months ago. I was considering using them in a 3d printer, but they weren't accurate enough for that unless i rewrote some of the firmware for the controller. You're right, they're not cheap, but they are very lightweight, and there are UAV/Drone batteries now that have an amazing Power to Weight Ratio. The one's i'm using can deliver nearly 3600 watts continuously for about 15-20 minutes. That battery weighs about 1.75 pounds. So i'm guessing it's considerably lighter than the air compressor :)

[@JamesiosoHo]

Thanks. I will check out a few actuators and see if they are suitable for my needs. Could you send me a link to those solenoid actuators?

[@xiaoli5668]

[@huntersihelp]

I have practically no knowledge on engineering, or exoskeletons etc.. But wouldn't you get more power from the artificial muscles (I forget what you called them) if they went farther down on the arm? Or maybe have 2 muscles going down further. Like what if you had them stick out a bit more at the top, and extended them downward more towards your wrist, that way if it worked (which I don't know if it would), it may give you more motion, and possibly more power...?

[@JamesiosoHo]

you would trade range of motion for torque. The power stays the same but you get more curling stregth instead of motion.

[@huntersihelp]
