There's always a point where it's time to stop talking and start doing.

I can't imagine how anybody passes a problem

that they know that they can fix, and doesn't try to fix it.

PITTSBURGH, PA

I feel an absolute obligation to serve.

Military service in my family goes all the way back to

the Civil War and World War II, Vietnam,

The mythology of my family

started with my grandfather, his pocket knife.

I always wondered what the heck did he ever cut with this thing?

There was never a moment where I thought I wouldn't become a soldier.

I did two tours in Iraq as a helicopter pilot.

I knew he was an amazing pilot.

He was the top of his class in flight school, so

I was always very confident in his piloting abilities.

He always reminds me of that as well, when we're driving.

I'm right at home in the chaos.

You've got three to four radios, ground guys talking, wing men talking,

In an instant your brain needs to be able to shift,

but then I got injured.

And that caused me to lose my ability to fly.

He was literally pulled out of Iraq and dropped home with three kids.

One day you're a soldier, and then over night

they rip off that tag and slap veteran on your chest.

And they don't really tell you what veteran means.

What is a veteran, what is it going to be to be a veteran?

Before I went in the military,

math was the thing where people were like:

"Hey, you are really, really good at this."

It's the thing that helps me understand the universe.

I thought: "Okay, I'll go get a physic degree of some kind."

He couldn't do it, he couldn't get the math right

and he said things were just getting jumbled up in his head.

I was diagnosed with traumatic brain injury,

some people call it concussion syndrome.

I missed math, I mean I loved just doing math

for the sake of doing math.

And so, I retaught myself a new way of doing math.

I went back and started from literally elementary school level math,

addition and subtraction type stuff.

I applied to Pitt and was accepted to the engineering program

and wanted to see if I could be involved in some engineering

helping veterans, and helping the people I care about.

A roast with potatoes and bacon.

Is that my job?

That's your job for the time being here.

The fact that my son has autism is just one little part of me.

But almost his entire existence is defined by that autism.

Tristan is pretty much non verbal.

-What? -Tristan.

Okay, if you're done buddy, you're done.

I'm sure that he has dreams and aspirations just like everybody else.

It's hard to want so badly to know what they're thinking

and to not be able to.

I found there was a field called rehabilitation engineering.

It's technologies that improve people's quality of life

and their independence.

I thought: "Man, if my son's ever going to be independent,

he's going to have to have these kind of things around him."

I you look up rehabilitation engineering,

the first thing that pops up is a place near Pittsburgh,

and I thought: "Man, I got to go be a part of that."

Human Engineering Research Lab (HERL) UNIVERSITY OF PITTSBURGH

It's kind of like Willy Wonka and the Chocolate Factory

except for it's robots instead of Oompa Loompas.

Our vision is a world where everyone with a disability

can participate on a level playing field

to their greatest extent possible.

The human, the right thing to do is to make things

not just able to be used, but to be used

with the same sort of joy or ease as I do.

We want to lift people up to be at eye level

with the person they're having a conversation with.

Climb a curb without it being this huge, drawn-out, dramatic thing

because the curb cut is not anywhere nearby.

To create an arm that can open a door, but also grab an egg.

To help transfer someone from a chair to a bed or to the toilet.

I had to prepare the software to support the research that we do.

We were incredibly inefficient on the computing side,

so the biggest change I think that I've helped to make is

to sort of standardize the technologies we use,

so that they're not a barrier.

Android is this underlying platform that you can just do anything with.

It has such an active community of people designing and innovating,

so that we can bring in somebody else's tools to solve a problem,

so that we don't have to learn a new technology each time,

we can just start working.

The type of person that I think has a propensity to join the military,

has a feeling of service and commitment

to something greater than themselves.

That's it.

Okay.

All the way up?

I have to remember to hit the right button.

You ready? Let me know if you need me to slow down.

Sometimes you get so close to the process itself.

Everything is wires and ones and zeros and

all of a sudden you get to the subject trials.

You have a human being come in and start using your product.

You see the potential for it to change your life

and all of a sudden it's this big wow moment.

I realized the service doesn't end when you get out of the military,

it just changes.

Debby?

They're so tough, my children.

They're so much tougher than I am.

Every now and then, I'll see them solve a problem and I'm like:

"Man, if they can do that, they're going to be just fine."

Those moments come to me and I feel such peace all of a sudden.

Will I ever get to talk to my son?

That's something I think about every day.

Of course I'm hopeful.

And that's part of why I became an engineer,

it's part of why I got into this field,

is that I'm not going to sit around and wait

for somebody else to fix the problem.

There's not a minute to be wasted

thinking about anything, but the good things that we can do.

To all those using technolog to build a better world
