00:01I'm actually going to use my arms so I can high-five so many people.

00:07One hundred and six.

00:09You're going to high-five a hundred and six people?

00:11Yeah.

00:12Aren't you going to get tired?

00:13No, because my robot is going to do all the work.

00:16Alex was born without a fully formed arm,

00:18a condition that affects around 1,500 babies born in the U.S. every year.

00:22I'm here to see him get fitted with a new arm.

00:25We have come a long way in the development of prosthetic limbs.

00:29You might think of the earliest prosthetic as maybe a peg leg for a sailor,

00:34but it actually dates back much further than that.

00:37In fact, over 3,000 years ago to ancient Egypt.

00:40The thought was that our lives have a finite length,

00:43but that the afterlife is eternal.

00:45And according to the theology of Osiris, the body needed to be complete,

00:49because the soul would leave the body, in theory,

00:52and every night come back to replenish its energy in the body,

00:56and it was so important that that body be full.

00:59And so there are many instances of prosthetic noses, ears, toes, and limbs

01:05which were used in ancient Egypt to ensure that the body was complete.

01:09But a lot of those prosthetics weren't actually functional.

01:12So prosthetics developed from simply being aesthetic aids to actually becoming functional.

01:18Globally, there are an estimated 3 million people living without an upper limb.

01:24Over the last 10 to 20 years, we've seen remarkable advancement in the development of bionic limbs.

01:29The problem with these prostheses is they typically cost on the order of $20,000 to $100,000.

01:34Now here at UCF, they are building an arm which can be used and manufactured for much, much cheaper,

01:41like 1% of that cost.

01:44How did you get inspired to design an arm for children?

01:48I was on my way to work and I was listening to the radio

01:52and there was an interview with the person who developed the first 3D printed hand.

01:57And I went into my research lab and I said, you know, I have to get part of this.

02:01What can I do to help?

02:02And then we had Alex's parents contact us directly saying, can you build our son an arm?

02:07The arm itself is completely 3D printed and so are the joints between the fingers.

02:12So there's a cable which runs down the length of each finger and back into the hand.

02:17They would normally be connected up to this servo motor here.

02:20Now the idea is to trigger this motor via the arm of the person who's wearing it.

02:25So they would wear three electrodes on their upper arm.

02:28When the person wearing the arm squeezes their muscle, there's a little electrical pulse

02:32which triggers this motor to pull in 180 degrees.

02:36One pulse will close the hand like this and then another pulse will relax it so it opens back up.

02:42Our arm provides a level of self-confidence to the children.

02:45Whenever they're going to school, there's questions asked like,

02:47what happened to your arm? Did you get bit by a shark or run over by a car or something?

02:50After we gave them the arm, it quickly changed to, oh, that's a cool arm.

02:54How does it work? Where'd you get it?

02:56I like to do stuff on my arm.

02:58I like pick up stuff, hold my paper when I'm drawing.

03:01I actually bring it to school so I can actually do other stuff.

03:063D printing is relatively new technology, but it provides us a low-cost solution to be able to create things.

03:13So we can print something out and say it doesn't work.

03:15Just redesign it and print it out again the next day.

03:17We produce our arm for just about $300 now,

03:19whereas some of the prosthetics on the market can go upwards of $40,000.

03:23Insurance companies typically don't want to pay for it for kids,

03:25because every six months you're going to have to replace it as the kid grows.

03:28But this allows us to be able to reproduce an arm for about maybe $100 and just print out anyone.

03:33How important is the aesthetic design, the artistic design of the arm?

03:37We thought kids just wanted to blend in and feel normal,

03:40but we found it's much more about personal identity and expression.

03:43We want to make sure the kid is expressing himself or herself with the arm.

03:47Self-expression for a kid is very important.

03:48We have one sleeve right here.

03:50This one is actually themed around the Disney movie Tangled.

03:52We provided this for a little girl named Madeline.

03:54The design is so simple that it is easy to print out on location

03:57and put together even with very little technical knowledge.

04:00And also the functionality of the design,

04:02with only three electrodes actuating the one servo,

04:05make it so that people can learn to use it very quickly.

04:08And that, I think, is what makes it so powerful.

04:11Think I'll have any luck there? 50-50?

04:1350-50.

04:14All right.

04:17I can give it to you.

04:19Yep.

04:20I am excited right now about trying out and how to do some results

04:24and do some things I've never done before.

04:27I want to play video games with it and hug it to hands.

04:30How have you been able to crack this problem that other people haven't before?

04:35We have an incredible team of very diverse backgrounds.

04:40And so bringing all of our common experience together,

04:43we were able to find this type of solution.

04:45Our main base is in Orlando, Florida at the University of Central Florida.

04:49We have our designers in California.

04:51I'm here in Germany.

04:53And everywhere in between, we have people trying to help us and support our project.

04:58Although it's challenging, we're making it work.

05:00A lot of our communication comes through Microsoft OneNote.

05:03And we use this product to be able to share information through each other,

05:06specifically since Albert is in Germany.

05:08So that's a whole ocean away.

05:10I think the best part of OneNote is that you can edit it from anywhere in the world

05:13and have it simultaneously update anyone else on the project.

05:16So being able to get updates from my team and see the progress they're making

05:20enables me to help do my job here in Germany.

05:22What is the collective project?

05:24Microsoft is looking for students who are wanting to impact their community with great ideas.

05:29And they're looking to rally their communities and the world around them to help bring it to life.

05:33Our biggest needs right now is, one, we need funding.

05:36We need more donations to be able to make this a reality and make these children's dreams come true.

05:42You want to provide free arms to every kid who needs one?

05:44Absolutely.

05:45We don't feel like people should profit from a child without an arm.

05:48We're hoping for people to jump on board and help develop arms for their local area.

05:52If they want to help with design, they're more than welcome to join our project and be designing arms.

05:57They can be printing out arms and helping fit them for their local community.

06:01Or they can just send us advice on how to best tailor these for the future.

06:06We can use all the help we can get.

06:08Where do you want to see the limitless arm go?

06:10My hope for the future is to be able to increase the functionality of the arm.

06:14To encompass maybe an elbow or even an upper limb socket.

06:18And then be able to produce this on a larger scale for as many children in the world who need it.

06:24As each child comes to us, we really understand and appreciate the need for readily adaptable,

06:30readily deployable solution to each individual and unique biology.

06:34We're trying to get an elbow going for Alex.

06:38So he can have not only hand movement, but he can also move the elbow as well.

06:43To overcome that, we have to make this also bigger to be able to put another servo in there.

06:47We like ideas.

06:48We're not just, this is our way, this is how it has to be.

06:51Anything's possible.

06:52We like to broaden our field as well.

06:55I think we're just at the beginning of something really great.

06:58And I hope that with a little bit of help, we're going to be able to take this to the UN and UNICEF

07:02and really impact children all over the world.

07:04Thank you guys for making this big project for me.

07:07That's fantastic.

07:08Thank you so much for chatting to me.

07:11You're very welcome.

07:14This video was supported by Microsoft OneNote.

07:17In their collective project, they have identified student groups around the country

07:21who are working together using their software in order to change the world.

07:25And the whole point of the collective project is to bring people together.

07:28And you can get involved as well by clicking on the link in the description.

07:32You could help by providing new designs for arms by helping with software

07:36or even 3D printing in your own community.

07:38And that will help get more of these arms out to the kids who need them.

07:42So I really want you to get involved.

07:44Check out the link in the description.
