Realistic Robot Arm: Meet the Modular Prosthetic Limb!
Вставка
- Опубліковано 15 жов 2024
- This realistic robot arm and hand was one of the coolest things we saw at the DARPA Robotics Challenge event--it's a technology that's already being field tested on patients. We chat with Michael McLoughlin, Chief Engineer at the Johns Hopkins Applied Physics Lab to learn more about the challenges of building a modular prosthetic limb that has the same dexterity as a human hand, and its potential applications.

Thanks for watching!
Very natural and stable design. It's really impressive. The control method is something to be concerned, though, but some amazing research has already decoded that too to the most natural level of control. The following years will sure be amazing.
A lot more impressive than the last robot video, considering this one is actually doing something and has a purpose.
Different type of robots - this is for human application, and the other is for human extermination ;3
The true art of engineering.
Wow! That is the most impressive robot/prosthetic hand-arm demo I have ever seen by far. Incredible!
Holy shit, this is actually really impressive. Much better than most of the robotics you see. Other things are really more like puppets, this is actually something that could legitimately serve as a replacement arm and hand. Great job Johns Hopkins Applied Physics Lab!
Very cool. If I had an arm amputated this is what I would want, its the coolest prosthetic arm I've seen so far.
Wow this looks really organic. Once the neural mapping thing comes along this technology can really help the people with missing limbs.
It's black with white and gold acccents...
*Icarus by Michael McCann starts playing*
This is pretty impressive. Give it another 10-15 years and it might be possible to mass produce to the populous. I know I'd want one.
Great videos from Tested! And I like it very much to see further resourses in the descriptions.
I want to see someone using this. Neural mapping with prosthetic limbs always interest me.
Really nice to see that the fingers can also move sideways to a certain degree.
This is pretty impressive. I recently learned that neuroengineering is a real field of study. I'm now debating on learning neuroscience after getting my bachelor's in computer engineering.
WOW. Veterans and other people in need of this will be very happy.
This is really amazing, the development for these is going so fast.
I can definitely see that in maybe 50 years in the future people would actually want to get these instead of their human arm/hand to increase the functionality.
Engineering improves so quickly
I like the big red stop button for when it malfunctions and starts crushing your unmentionables.
I wish you went to the Virginia Tech version, I go to school there and that'd be really cool to see it on tested!!
Very good but just like the others u have seen you have not used the palm mussels which if you had would have multiplied the force and allowed for better movement
Which competition is he talking about? He says "In this Competition" at 1:40. Is he speaking competition in general? or is there any specific competition where robotic hands are tested.
this is the most decent prosthesis out there right now
I saw something similar on the Hannover Messe 2015. Very impressing.
P.S. Yes, DX:MD is comming!
Wow, that much power without a tendon system? If it is holding something at the limits of the motors power, how long til they burn out?
How do they send signals from the arm back to the brain, or is that even possible? For example how do you know how soft or hard something is?
Give it to people who try human transmutation
Underrated comment. Here, have a reply.
if its humanlike, can the ringfinger be extended from a fist like the middlefinger can? or does it behave like a human hand via programming, ie. limiting its movement.
if i were to have such an arm, i would not necessarily want to have an exact analog of the arm i have now. i could have anything i wanted to imagine, make a fist backwards, have a lighter in my indexfinger or all sorts of other crazy stuff... two thumbs opposing each other on each side of the hand? why create an exact replica if i may think or want something completely different potentially better?
Since it's modular, I want to see them make a claw attachment like the sort of claws they use on mars rovers or factory robots.
On a side note, I noticed how the forearm was hollow. Could that be used as storage space for alternate utility hands? Like a drill hand?
THEY PLAYED US LIKE A DAMN FIDDLE
like a Damn fiddle !!!
+That Guy ThatWearsClothes Damn Fiddle!!
Such a lust for memes ! WHOOOOOOOOOOOOO ??!!
They played god
Jax whacks hacks across their backs.
One step closer to robots taking over!... COOL!
Cyberdyne here we come!
rb hws Cyberdyne all ready exists and are producing exoskeletons. :) www.cyberdyne.jp/english/
Kristoffer Grannas the real cyberdyne is google
Doan08 yeah you are right :)
rb hws KANEDA!
rb hws better Skynet than Ummah, at least skynet I can respect
1:28 This kid just saw a chilling vision of the future. A robot stomping on a human skull was involved.
So with the chip that's implanted into the brain, what would happen if said person had a seizure? Would the robotic arm also react? My understanding is that the brain itself remains fine, it can't communicate to the body, so because this thing is tapping straight into the brain, wouldn't that mean that they could still control the arm? Really interested in this.
Holy crap! If you ever study the kinematis of a human thumb, you would know this one's is very very very impressive!
Mr. McLoughlin looked so heartbroken and confused at the beginning, like "Who are these people? Te-Tested, what? What the f**k's going on...?"
But this almost makes me wanna lop my own arm off to get a replacement... almost, I say. I'm imaginative, not stupid :D
Well, not entirely, anyway...
This was the most realistic. Looks like a real arm shape.
My question is though can we ever truly have mastery control of prosthetics without surgery to the brain? Because the amount of control between the two is pretty incredible.....
What if you run out of battery power right when you're in the middle of something?...
Hey guys I was wondering if u can make a Tron identity disk and/or the suits from Tron. It maybe an old movie but I think u guys can make it look awesome. 😀
anyone else half expecting the robot to give him the finger in the last scene? :P
great tech. Im finishing my EE course this year, so hopefully work on something like this one day...
nothing is stopping you from starting a robot project right now. Just do like 5-10 hours one day a week on it and you will progress. That's what I'm doing.
I bet theres gonna be Big Boss-arms for sale from MGSV when these hit mainstream. :P
But THEY PLAYED US LIKE A DAMN FIDDLE
Do they have a forarm or hand only model
cool, but likely very expensive with custom BLDC motors.
so, possible design using stepper motors (fairly common / affordable):
fingers, 6x NEMA-14;
wrist, 2x NEMA-17;
curl/shoulder, 3x NEMA-23.
weight: approx 6 lbs (for motors, for 5-fingers)
( leaving out most intermediate calculations, etc... ).
strength:
approx 35lbs grip (with a 1s open/close time);
approx 50lbs wrist turn/deflection (2s);
approx 40lbs curl and lift strength (4s over full range).
cost: approx $187 for motors for 5 fingers, approx $175 for 4 fingers.
cost would be lower if motors are bought at bulk prices (approx $130 for the motors).
other materials, probably would need a frame for the arm (likely plastic and/or aluminum), and likely some pulleys and thin steel cable (these motors would not fit in the joints, so would need to work via pulleys).
power required: probably around 200W peak (all motors going at the same time at full power, assuming motors running at 12v at rated values).
or such...
Brendan Bohannon Yeah, i'm assuming you can also get a TON more power out of a stepper too.
***** vs BLDC? overall wattage vs size and weight is likely fairly comparable (it mostly has to do with heat), and these aren't particularly large steppers (the finger steppers are more like what would be found in a printer, and the larger ones are more like what would be found in a bench-top CNC).
typically, BLDC motors are designed for high-RPM low-torque (so are "weak" in this sense), whereas steppers are typically designed for lower-RPM high torque (so, they turn a lot harder but tend to be slower).
commodity steppers mostly are likely to be a fair bit cheaper than custom-made high-torque BLDC motors.
ultimately, how quickly and with how much power a load can be moved comes down to wattage. more watts means more power.
some of the larger motors listed could peak about 100W, or about 1/8 HP, so probably pretty good. rated power is closer to about 36W though (generally, the area between rated and peak is ok for short bursts, but above rated the motors will get very hot).
of course, a lot of watts also means needing a good power-source, so this would need some fairly powerful batteries (random thought of someone sticking in multiple cordless power-tool batteries).
Brendan Bohannon Haha, I appreciate the great explanation but I don't really need it (I do a lot of robotics). But yeah, I guess i'm just influenced by cnc steppers and over estimate steppers in general. We take a lot of caution around cncs, there's too many stories of people having their hands crushed.
***** yeah. big steppers are pretty powerful, and can easily do some damage. little ones are not quite as powerful, and most of the types I had listed are not all that big.
Brendan Bohannon Just curious, but what's your background? It's always a pleasure to meet people who don't find this stuff boring.
oh shit deus ex is coming.
Xiu Greyson Deus Ex?
Cmon, even your avatar image
It's for Big Boss
Punished Jack big boss had it in the 60s dues ex is in like real soon like our time soon.
Xiu Greyson 80's actually
Xiu Greyson I know... TPP is actually in '80s
It was a joke
Punished Jack the hand that bigboss is using is from peace Walker and the kgb dude had it for a while. yes its the 80s but still
Can it detect when it has received damage?
Was anyone else just waiting for the robotic hand to give someone the finger?
I was.
Jonas Lundh Bet it was the first thing they made it do.
Yep
i was

Goddamn guys hold your horses this is still a WIP. There are many other sensors there that we haven't mapped out or have functionality to, those being: proprioceptors and nociceptors (including thermoreceptors). Despite having motor functionality down like it ain't no thang, the sensory stuff needs some work. We still have the problem of phantom limpane, plus the person can't tell how their arm is oriented if they don't look at it. Once we have both of those sensory modalities communicating with the PNS (or CNS via microelectrode patch) then we gotta figure out how to prevent the immune response and glial scarring from occuring, otherwise the patient has to either get multiple surgeries over their lifespan or have to deal with always having a weak immune system. Once that is done the next step is figuring out portable power. It may seem simple the way this arm was presented in this video but goddamn it's a huge complicated project but major leaps were made in the field of robotic prosthetics thanks to APL's work.
But how FAST is it? He mentioned typing on a keyboard, but I just have a hard seeing, from the speed of the "demo" that it would much use for typing...
How's the batterylife?
It would of been nice to see someone use it.
Any one know where to find Norm's shirt? or the artists name?
Interesting, could be of great use.
Man they should have put servos in so that it could curl 1000 lbs and pinch 200 lbs LOL. That would be awesome.. like Will Smith in iRobot and how he has the super strong robot arm. This is amazing work.
Spacemonkeymojo The robo arm may be able to support that but the body wouldnt be able to.
***** we'd probably rip our own arm out since the limb is essentially using your arm as the anchor poin
Te Amasin Spoderman Yeah, exactly. You'd need that whole side of your upper body to be modified to suit it, at least. Imagine what we'll be able to do when full body prosthetics are available.
+dino seen They'd make you wear a half top skein with a buckle. Quite practical but you'd need to be able to KNOW that you'd be able to carry it and it would be balanced, which could be another issue...
Shadows_Assassin "a half top skein with a buckle." I'm afraid I'm not familiar with that. What is it?
Was that John the Fisherman standing with you at the end?
That is beautiful, I would even go as far as to calling it 'sexy' but, there is one important question. Does it come in red?
This is cool. and with it being compact, it will eventually be applicable.
But I believe the real breakthrough (and possible Nobel Prize winner) is going to be with the interface between Brain and prosthetic. If one can find a way to directly translate neuron firings to mechanical-electronic binary instructions and vice versa, in a near 1-to-1 performance (minimal lag) then we could be in the age of Deus Ex (video game) by then. Hopefully it comes within our lifetimes.
surft direct nervous tissue connection has already been done, and the brain implant option the guy was talking about involves implanting a silicon chip into the parts of your brain associated with movement. so yea already done.
that's not to say the the chip is the best way. its actually 15 years old and the brain develops calluses over time, reducing its effectiveness. newer designs include a very promising silicon dust that will capture a more accurate picture as well as not suffering the degradation.
+surft Within the last month one man did get a prosthetic hand with a connection directly to the brain. Apparently its touch sensors feel almost natural.
I can't help but think that there's a lot of empty space in that forearm that could hold some cool stuff, like a swiss army knife or a lighter...
really cool !
Getting closer and closer to the arm in Treasure Planet. I feel like that's the end goal for me.
That's amazing. Its strong, but can it hold an egg without breaking it?
So cool!
Amazing.
? is if the person was born with no arms how well would this work could it have the reaction time as a non robotic arm for playing video games
"hmm oohKay..." Hahahaha!
so will this arm be customizable to look like MGR Raiden's arm, or any cool videogame arm? because you know a lot of people now will want to have a Bionic! AAARRM!!!!
I couldn't stop saying wow
Decoding the brains movement signals, are we already there?! Ultimate VR input device anyone? Now we only need a save way to paralyse your real body or something.
''Snake? Snake? Snaaaaaake!''
Who can dislike this????
thank you
Does that arm change behavior in someone with a 'complex' brain sensor that takes different psychotropic drugs?
Now that's a real question. I bet it wouldn't be able to read the brain waves or it would freak out lol
Dread Naught Imagine it to be programmed to slap yourself each time you smoke, that would be a way to finally stop doing it ;-)
+Dread Naught I'd image the arm would learn and differentiate the signals, although that may still be serious issue...
can u give me 3D file about this robot hand ?
Is the hole in the arm a cup holder lol
Link up with Boston dynamics and put two of these on their Pet man! Boom, the first terminator is born! Oh wait...
I guess you could say that arm would be quite *handy* to have.
The T01, only a hand but a killing machine. This can be used for any military use.
By Skynet.
As soon as those arms have the fine motor control to use controllers keyboards and any other intricate acts they will have been
perfected
Winry Rockwell wood love this. :-D yay references.
the robot is like.... where is my freaking head?
so I've been having trouble with my arm and if I ever have to chop off my arm a least it will be someone normal
Can I get one of these that's like, 20X stronger but the same size?
Designed for Cyberdyne Systems Model 101
If i lost a limb i'd wait until they made one that looks like the Terminators arm
When I read "modular" I thought you could replace the fingers or the whole hand for other things.
Are you Vietnamese and your first name is LOC ?
Imagine soldiers with this technolgy 😲
Here come the terminator model T1's
The arm will be better in Red...
Awesome
BIG BOSSU'S ARM!
I remember the episode of the big bang theory...howard and his "accident"...well there we go
YAY! T-800 is comming!!!
Come on man. John(s). As in Johns Hopkins. Don't forget the S
We are so close to being able to make the Iron Legion from Age of Ultron.
that is so cool i wonder if Obamacare covers for that.
Nope. Prosthesis isn't generally covered by medical insurance - Plus this device would cost $200,000+ custom made for a patient, not including the surgery.
My stepbrother needs this from the wrist to fingers.
Jeez, I can hear the Terminator 2 theme by just watching that thing.
Imagine the iron man like capablities o_o
Like if it was incredibly strong, and could take extreme force.
It could destroy our shoulders because of the arm's strength sending a shockwave around our body. And since our shoulder is the nearest point of impact, it's at risk of breaking.
just before this roll ads watched a new film about the terminator ;)
damn. how high does my r&d team have to be to get one of these?
A robo arm?
*Proceeds to chop arm off*
