[0:00] This is the world's greatest
goalkeeper because it's a robot.
[0:05] And it's really, really fast.
[0:07] - And this is Ronaldo, the
world's greatest soccer player.
[0:10] - Cristiano Ronaldo!
[0:11] Ronaldo!
[0:12] Ronaldo!
[0:14] - So the question becomes what happens when the
world's greatest player faces off against the
[0:18] world's greatest keeper?
[0:19] - Woo!
[0:21] - Now to even get to this point, I
had to survive the toughest of coaches.
[0:25] - Don't cut the corner.
[0:26] - The strongest of legs.
[0:28] - Let's go!
[0:29] - A lot of failure and a little blood.
[0:32] - Look at my hand.
[0:33] - But all that started for me right here at the
most iconic football stadium in the world when I was
[0:38] invited to play in the Sidemen
charity match, and I came ready to play.
[0:42] - Leftback.
[0:42] Mark!
[0:45] Biggest stage of football we can ever play.
[0:46] 90,000.
[0:47] - My second favorite moment was
when Speed tried to outspeed me.
[0:51] - Great challenge from Mark Rober.
[0:53] - Because my first favorite moment
was when I got to take a penalty kick.
[0:56] - Rober! Yeah!
[0:57] - And score a goal in front of
90,000 of my closest friends.
[1:01] Now to say this was a dream of a
lifetime would be an understatement.
[1:05] I've been playing soccer my whole life, starting
at 5 years old, and that's the kind of moment you
[1:10] only dream about as a kid.
[1:11] The problem was, now that I realized how good
that felt, I couldn't shake the idea that somehow I'd
[1:16] missed my life's calling to compete at the
highest level with the likes of Cristiano Ronaldo.
[1:21] Now normally because I'm generally uncoordinated,
[1:24] when I need to compete at the highest level, I
just rely on my brain, which means I know what it
[1:29] feels like to be a world-class
bowler, a world-class field goal kicker.
[1:32] - That's my boy!
[1:33] - World class darts player, jigsaw
champion, domino layer, and golfer.
[1:38] And so while that was a reliable plan B, if I was
ever gonna have a chance to actually compete in a
[1:43] sport with my raw athletic
talent, this would be my best shot.
[1:46] So with the cheers of Wembley still ringing in
my ears, I made my way back to the pitch to meet up
[1:51] with the one person I knew could prepare me for
the debut of my professional career, the goat of
[1:56] American soccer himself.
[1:57] - Mark, what's up bud?
[1:58] - Landon Donovan.
[2:00] How we doing?
[2:01] - And I cut right to it, asking if there's
anything I would first need to know before going pro.
[2:05] - Okay, so you're training twice a day on the field.
[2:07] - Got it.
[2:08] - And then an hour to an hour
fifteen in the gym every day.
[2:10] - OK.
[2:11] - After that,
[2:12] Calf raises.
[2:13] OK, 30 minutes a day, you're at home, calf raises.
[2:16] Every time you're running, ball
at your feet, ball at your feet.
[2:18] Forget about your ice creams
and your treats and your desserts.
[2:21] Lots of stretching, yoga, that's pilates as well.
[2:23] Talking to a sports psychologist.
[2:25] Keep your heart rate low
while you're doing all that.
[2:27] It's cutting, it's sprinting.
[2:27] Keep your hips mobile.
[2:28] Running, jogging.
[2:29] It's massage.
[2:31] 6 more things you
[2:31] - Could you just write this down for me.
[2:33] - Just read my book.
[2:34] - Oh, does it come in audiobook?
[2:36] - Yes it does.
[2:36] - It does?
[2:37] OK good.
[2:38] - Let me see what we're working with.
[2:39] - So we started by running a five drill
gauntlet to see if I had what it takes.
[2:43] Starting with the simple exercise of
kicking a ball straight up in the air.
[2:46] - Easy enough.
[2:48] Oh boy.
[2:50] - No, every time you mess up, you gotta take a lap.
[2:52] Lap.
[2:53] - What?
[2:53] - Apparently this is a pretty
common training technique for soccer.
[2:57] - Don't cut the corners!
[2:58] - My bad!
[2:59] - With every mistake meaning
a full lap around the field.
[3:01] - Try again.
[3:03] - Oh!
[3:03] - Take a lap.
[3:04] - Ah!
[3:04] - Drill number two was testing my aerial attack
where I had to practice heading a ball lifted up
[3:10] to Ronaldo's max jump height at 9.5 ft.
[3:17] - Was it close?
[3:18] Must have been good, right?
[3:19] - Lap.
[3:19] - Agh!
[3:21] Soccer's hard.
[3:22] - Test three was the banana kick,
[3:23] - Just like this.
[3:24] - Where we had to put spin on
the ball to bend it into the net.
[3:30] - Oh.
[3:30] - Not bad.
[3:31] - I got a not bad.
[3:33] - Not good.
[3:34] - I got a not good.
[3:35] I know, I know, I know. Lap.
[3:36] - Faster please.
[3:38] - The next two tests involved speed and accuracy.
[3:41] - So just like this.
[3:42] - This one we had to bomb a ball into
the goal from halfway down the field.
[3:45] - That's pretty...
[3:47] - So I gave it a shot and
actually made it pretty far.
[3:51] Away from the net.
[3:52] - Oh!
[3:53] - Lap.
[3:53] - Dang it!
[3:54] - But I was feeling optimistic about the final
test because that was aiming at targets at a much
[3:58] closer distance.
[3:59] So I was pretty sure I was running my last lap.
[4:02] - Don't cut the corner!
[4:03] - I barely cut.
[4:04] - All right, Mark, four targets, four balls.
[4:06] - I just had to hit the top right.
[4:09] - Oh, hit the post.
[4:11] - And then the top left, and then
the bottom right and the bottom left.
[4:15] - Oh!
[4:15] Is that even possible?
[4:22] I mean you could have just said yes.
[4:24] - Lap.
[4:25] Let's go.
[4:28] Corner!
[4:29] - It's like a foot, Coach!
[4:31] Ugh.
[4:31] - I love the effort.
[4:32] I'd, uh, I'd stick to science, bud.
[4:34] - Oh.
[4:36] - So with that resounding end to
my professional soccer career.
[4:39] - Thanks Landon.
[4:40] - It was time to start thinking
like an engineer and initiate Plan B.
[4:44] And so after consulting with the team
for a little brainstorm, this was Plan B.
[4:47] - If I want to be the best soccer player in the
world, I'll first need to defeat the best soccer
[4:51] player in the world.
[4:52] In other words, I need to switch positions and
make it impossible for Cristiano Ronaldo to score
[4:57] a goal on me by building the
world's greatest goalkeeper.
[5:00] But there's a problem with that.
[5:02] - Ronaldo kicks the ball at 80 miles per hour.
[5:04] So it will reach the goal line
in just a quarter of a second.
[5:07] Now for a goalie centered, then the
maximum distance he has to travel is 12 ft.
[5:10] That means he'll need to yeet himself to 40 MPH, then
slam back on the brakes to 0, all within 250 milliseconds.
[5:17] That's literally half the time it takes to blink.
[5:20] - In other words, I'm gonna need some really big
motors and a bunch of fancy cameras to track the
[5:25] ball so we can predict the
trajectory after only a few milliseconds.
[5:29] - For the fancy camera part, we got
ourselves 12 high-speed infrared cameras.
[5:33] So while a normal camera sees me and Ian and
anything else that's randomly in the background,
[5:38] those 12 cameras only see
one thing, this soccer ball.
[5:41] And that's because if you look real close on the
soccer ball, we've got these little gray stickers
[5:46] called retroreflectors, whose surface is made up
of tiny little glass spheres that bounce any light
[5:51] right back at the light source, like you see
with those markers on the road, or with road signs.
[5:55] So these cameras blast the scene with infrared
light, and because they can only see infrared, the
[6:00] retroreflectors glow super
bright relative to everything else.
[6:03] So when you compare exactly where the center of
the bright spot is in all 12 images, and then do
[6:08] some really complicated math, you get a 3D
position of where the ball is down to the nearest
[6:13] millimeter, 500 times per second.
[6:15] For us, that means 6
milliseconds after being kicked.
[6:18] We now have 3 data points that we can draw a
line through to predict where the ball will end up.
[6:22] In other words, by the time Ronaldo's kick has
traveled exactly this far, the goalie robot will
[6:27] already know exactly where it
needs to be to block the shot.
[6:30] So we first needed to validate our tracking
system by recording a kick that was faster than 70 MPH.
[6:36] And apparently Ian got Coach Landon's scouting
report because when I showed up there were two D1
[6:40] soccer players already there to
take the kick instead of just asking me.
[6:44] - Ian, I specifically remember
telling you, I can do that for you.
[6:46] - I remember you saying that, I do.
[6:48] - But I'm nothing if not a team
player, so I volunteered to get in goal.
[6:52] - I'm so confident not only am I gonna block your
shot, but I'm gonna get it's speed at the same time.
[6:56] Please don't hit me.
[6:57] What have I done!
[7:02] Medic!
[7:04] Look at my hand!
[7:05] - But it would take a lot more than that to keep
Mark Rober down because it's not about how many
[7:09] times you fall, it's about
how many times you get up.
[7:11] So I cleaned my wounds and
courageously stepped back in the line of fire.
[7:15] - Let's see what you got.
[7:18] 66.
[7:20] - That's not bad.
[7:20] - Which was good but not quite fast
enough, so we had to keep trying.
[7:26] No! Wow! 67!
[7:28] - Which I'm assuming will be good enough for the
top comment, but not good enough for our top speed.
[7:36] - 71!
[7:38] - We now had the data to verify our design would
actually work, which meant we were finally ready
[7:43] for a 10 second build montage.
[7:58] - Well this is 1 to 1, no?
[7:59] - Yeah, that checks.
[8:00] - Here's how it works.
[8:01] Those cameras we talked about all plug into a
computer that figures out super quickly in real
[8:06] time where the ball is going to end up, and then
it sends that answer to the pair of 50 horsepower
[8:11] motors right here and here.
[8:12] Then each of those motors is attached to a
belt that whips our carriage-mounted goalie to the
[8:17] exact spot the ball will be plus
or minus the width of a human hair.
[8:20] So all that was left to do now
is to see if it actually worked.
[8:23] - You wanna try to take a shot?
[8:25] - Do you wanna try and block a shot?
[8:26] Hands away from the keyboard.
[8:28] Here we go.
[8:32] Oh wow, OK, Mark Rober.
[8:36] - Better luck next time, Mark Rober.
[8:38] - Now to appreciate how tricky that is.
[8:39] There is a ton of data with over 5000 camera
frames updating the goalie position in real time
[8:44] every second.
[8:45] The only problem was this warehouse was basically
in the middle of nowhere with zero internet, so I
[8:49] hit up my besties at T-Mobile, and they hooked
us up, which meant we were firing on all cylinders
[8:54] thanks to the best network in the US.
[8:55] For my second shot, I tried to
get tricky with the off-speed kick.
[8:59] - Bring the heat.
[8:59] - Three, two, one.
[9:02] Wow!
[9:02] - There's no fake outs.
[9:04] - You coded the Panenka, dang it!
[9:06] There's no fooling this guy.
[9:07] - You wanna go again?
[9:08] - Finally, in frustration, I just
reverted to raw power with a kick
[9:13] that would make Coach Landon very proud.
[9:15] So while it wasn't yet perfect, it was
certainly looking very promising, even if I'd already
[9:20] identified a couple weaknesses.
[9:23] - Oh. Hey,  we weren't ready, redo, redo.
[9:25] - So to make sure we had truly worked out all the
bugs before facing Ronaldo, we decided to gather
[9:29] real world data by heading out to a
local high school for some actual competition
[9:33] in the form of five shooters of increasing
difficulty culminating with the final boss
[9:38] Deestroying, AKA the
strongest leg on the Internet.
[9:42] - What's good?
[9:45] - And we kicked things off with what was
certainly the most intimidating opponent to date.
[9:50] - How fast can you kick?
[9:51] - Really fast.
[9:53] - Well, guess how fast Mark Rober can move?
[9:55] - How fast?
[9:56] - That fast.
[9:56] That's faster.
[9:58] All right, Science Bob, do the honors.
[10:05] Better luck next time, Jonah.
[10:08] - OK.
[10:08] - Now in hindsight, I do admit my round one
sully against Jonah might have been a bit extra.
[10:13] - That's right.
[10:14] - But regardless, it's on to round two versus Tory.
[10:17] - All right, Tory, what's your strategy?
[10:18] - Corners.
[10:19] - Which corner would you say?
[10:20] - Left.
[10:21] - She's going left.
[10:22] - No!
[10:22] - Tory, best of luck.
[10:24] The concentration.
[10:27] Tory! That was a good effort.
[10:29] Well played.
[10:30] - And with two of six down, I think it's worth
pointing out now that we were out in the field, I
[10:34] once again asked T-Mobile for an internet hookup,
and that's when they suggested, why don't you just
[10:38] run the entire robot on 5G?
[10:40] And I said, well, in order to stop Ronaldo,
it would need to start moving in less than 10
[10:43] milliseconds, and that's 1/40
the time it takes to blink once.
[10:46] So there's no way wireless can keep up with that.
[10:48] And they said, actually, it can.
[10:49] And I said, wow.
[10:50] And sure enough, it actually worked.
[10:52] So like before, the camera sees the ball, but now
when the computer picks up where it's going, that
[10:56] signal flies through Google Pixel rocking
the tensor chip, ensuring super fast 5G speeds
[11:00] wirelessly through the air across
T-Mobile's portable private 5G network
[11:03] straight into the robot all in less than 10
milliseconds, which means by the time your brain
[11:08] could even register the ball's moving,
this robot has already moved to block it.
[11:11] Which is wild.
[11:12] Our third opponent Kazushi came
in hot making some very bold claims.
[11:16] - How fast can you kick?
[11:17] - Like 70 MPH.
[11:19] - Really?
[11:19] Kazushi.
[11:20] I'm gonna ask again now that I'm holding a
radar gun, how fast can you kick a soccer ball?
[11:24] - Like 60.
[11:26] - Man, they just called your bluff.
[11:28] - All right, Kazushi, let's
see your 60 mile an hour blast.
[11:31] - Alright, actually like let's go 55.
[11:33] - Okay, 55.
[11:36] Oh wow! Wow!
[11:39] - Yeah Let's go!
[11:41] - Unfortunately my goalie couldn't keep a
clean sheet due to some accuracy issues.
[11:45] - For the record, 54 MPH.
[11:47] - But failure is part of the process,
so I took note and graciously moved on.
[11:51] - Get out of here, Kazushi.
[11:53] He walks at 2 miles an hour.
[11:54] I know that.
[11:55] - Our 4th kicker Xenia stepped
up and just ripped a real beauty.
[12:01] - Yeah! Let's go!
[12:02] - How did that save that?
[12:03] - No chance!
[12:05] Xenia, what the heck?
[12:07] You broke my left arm.
[12:08] - That's my bad.
[12:09] - I think it might have actually hit the post.
[12:12] - Honestly, that's better than scoring.
[12:13] I broke it.
[12:14] - Xenia, get off my field.
[12:15] - My robot counterpart was definitely starting
to fall apart, but my hope was he could keep it
[12:20] together for at least a few more saves.
[12:22] - Are you a lefty, Neo?
[12:24] He's not even saying, oh, Mark, he's tricking you!
[12:27] - Let's go, Neo.
[12:28] - He is left-
[12:28] No, he's right!
[12:29] - Let's go Neo!
[12:30] - Boo!
[12:30] Yeah, let's go!
[12:32] - Good save.
[12:33] - We got good news and bad news.
[12:35] We blocked the shot, but we seem
to be losing material on each one.
[12:39] - You're falling apart, man.
[12:40] - Neo, this is for you.
[12:41] That's a piece of me.
[12:42] Better luck next time, Neo.
[12:44] - Robot Mark Rober was on his last leg, but there
was no time to tend to wounds when the final boss
[12:49] was waiting.
[12:49] - I've watched all these boys compete.
[12:51] I've seen them do their thing.
[12:52] - Yeah, but we've also been
calibrating and learning ourselves.
[12:54] - I know, but you haven't
seen a leg like mine before.
[12:58] Calibrate all you want!
[12:59] - First video of yours I saw, you bombed
what would have been like a 70 yard field goal.
[13:03] - Its light work.
[13:04] - The wind was a tailwind.
[13:05] - How do you know? Were you there?
[13:06] - I can see your shorts doing this.
[13:09] I've heard enough talk.
[13:10] Now I want to see the action.
[13:11] - So I gave him 3 tries.
[13:13] Simple rules.
[13:13] Best of 3 wins.
[13:15] - You're not gonna ask my strategy.
[13:16] - I don't need to know your strategy.
[13:18] You just kick it real hard.
[13:20] - See if you're ready for this Mark.
[13:24] - (laughing)
[13:25] - Right at me!
[13:27] Oh, come on!
[13:28] - I wanna test the body, see what the body has.
[13:30] - 65 miles an hour, by the way.
[13:32] - Not bad,  I'm just warming up.
[13:33] Let's try to hit 70 right here.
[13:36] - Yeah, oh boy!
[13:38] (laughing)
[13:40] - He blocked it though!
[13:40] - He blocked it!
[13:41] - But he's hurt.
[13:42] You gotta substiute him.
[13:43] - I knew we should have used better glue.
[13:45] - I broke his robot, bro.
[13:46] This man spent months designing
this thing, building this thing.
[13:49] He was bragging about carbon
fiber this, steel foam this.
[13:53] - I think we might require a goalie swap.
[13:55] - So after a quick substitute of my critically
injured goal keeper, it all came down to this -
[14:00] the final shot.
[14:00] And with the score tied, it was winner takes all.
[14:03] - I think we need to move you closer.
[14:04] - Closer?
[14:05] - Robo goalie is optimized for the penalty kicks.
[14:08] - Let's see how optimized he is.
[14:09] - Alright.
[14:16] Let's go!
[14:18] - And with an absolutely heroic effort, literally
destroying himself to get an extra foot of reach,
[14:25] he made the save.
[14:26] Well, almost made the save.
[14:32] - Optimized, huh?!
[14:33] - So we have some strength issues.
[14:35] To be fair, I feel like
the tracking is working well.
[14:38] - Yeah.
[14:38] It's been there every time.
[14:39] - But what do you think our
chances are against Ronaldo?
[14:42] - If you fix the strength issues?
[14:44] I think he's got a pretty
good shot against the GOAT.
[14:45] - While these real world tests were encouraging, it
was clear we still had a bit more work ahead of us.
[14:50] Ronaldo kicks even harder than D, so we clearly
need to level up the robot's strength and durability.
[14:56] - Dang it, he kicks hard.
[14:57] - But even the speed and
accuracy would need some work.
[15:00] For the strength issues, we knew from the
beginning this would be a huge challenge because
[15:04] the goalie needs to be strong enough to
withstand an 80 mile an hour kick, but the bulkier and
[15:08] stronger something is, the
harder it is to move it quickly.
[15:10] - But it's a trade-off, just like how it's harder
for me to move this big heavy bowling ball back
[15:15] and forth versus this
lightweight, flimsy little ping pong ball.
[15:18] - So to solve that, we just use an old trick I
learned at NASA where you sandwich a piece of
[15:23] dense foam between two sheets of carbon fiber.
[15:25] - And now you've got something that's really
lightweight, weighing less than a gallon of milk.
[15:30] And yet...
[15:31] ...it's also super strong.
[15:38] Abs baby.
[15:39] - But this solution had one
critical oversight, our attachment point.
[15:43] When we looked at the footage in slow motion, it
was clear before the ball even made contact, the
[15:48] damage had already been done, and that's
because we had to pull so hard on the goalie to get it
[15:52] moving that fast.
[15:53] We were peeling off the bracket and
the whole back face in the process.
[15:58] So we reinforced the attachment of the bracket
by adding 4 large diameter shear bolts and a carbon
[16:04] fiber crossmember, and once we ran a test to
simulate running the goalie with the old method
[16:09] versus the new method it was clear
this would make a huge difference.
[16:14] To solve the accuracy issues, we doubled the
number of cameras to 22, which means we've doubled
[16:19] the number of eyes looking for the ball stickers,
so we no longer have the issue where we sometimes
[16:23] would lose sight of the ball.
[16:25] And finally for the speed, we just pushed the
motors to 250% of the standard power levels, which
[16:30] doubled the robot's speed to 41 MPH.
[16:33] So with all those fixes in place, it was time for
one final test to see if we were finally ready to
[16:37] face Cristiano Ronaldo.
[16:41] And the early indicators pointed to yes, we were.
[16:43] - The brain is not meant to see
things that large moving that fast.
[16:48] - It triggers your get out of here now response.
[16:51] - But just to be sure, we
collected a few more data points.
[16:58] - I think I'm really liking our chances.
[17:00] I think this is ready for the pros.
[17:03] - And with that, let's go.
[17:05] We were off to Portugal.
[17:09] - Did you get it?
[17:10] - And it turns out Portugal is a beautiful country
filled with really cool people, but unfortunately
[17:15] we had no time to enjoy it because we had only
one day to prepare to face off against their most
[17:19] famous countryman.
[17:21] And out of the gate disaster struck because once
we got to the field and set things up, our goalie
[17:26] robot was basically missing every shot.
[17:30] - Wait, did it move?
[17:31] - No.
[17:31] - But did you want it to move?
[17:33] - Yes.
[17:33] - Oh...
[17:34] - Something is wrong.
[17:34] - We couldn't get a good read on the ball
position because there was so much noise in the tracking
[17:39] signal, and this was really
confusing because we hadn't changed anything.
[17:42] - I wonder what that noise is from, it was
so clean when we're in the states, right?
[17:46] - I'm kind of surprised.
[17:47] I'm looking at sources of variability.
[17:49] - And so as we stepped through all the sources
of variability one by one, when we looked at the
[17:53] graph of the ball position from all the cameras
and zoomed all the way in, the ball seemed to be
[17:58] wiggling up and down just a tiny bit, about 1500
times per minute, even though the ball itself was
[18:02] perfectly still.
[18:03] And 1500 wiggles per minute coincidentally was
the same RPM frequency of an engine you would find in
[18:09] a forklift that happened to be moving all
around our field for the previous 3 hours.
[18:15] And that meant the motor vibrations were
traveling through the tires through the ground and ever so
[18:20] slightly wiggling all 22 of our cameras, causing the
super delicate tracking system to basically be useless.
[18:27] And so as soon as we cleared out the forklift,
sure enough, the signal cleaned up perfectly and
[18:32] we got back to blocking shots smooth as butter...
[18:36] ...for the most part
[18:38] So while Ian stayed back to tackle that final bug
in the code, I headed off to a Portugal World Cup
[18:44] qualifier game to do some last
minute recon on their star player...
[18:49] before he would come over to meet
our robot goalie after the match.
[18:52] Now, to be honest, I didn't learn much about
Ronaldo's kicking game, but I did learn that his
[18:57] fans are very loyal.
[18:58] - Would you be willing to
unsubscribe for Ronaldo for me?
[19:00] - Absolutely not.
[19:02] - Because I'm only 5 million subscribers away
from passing him on YouTube, and suffice it to say
[19:06] - No, no, no.
[19:07] Absolutely no.
[19:09] - No.
[19:09] - I would not be getting myself
any closer while in this country.
[19:13] But the good news is I know of another country
that has 5 times the population of this one, so do
[19:19] your thing Argentina.
[19:20] Now seeing that I was mere hours away from the
greatest showdown of my life, I headed back to the
[19:24] field to wait for Ronaldo to finish
his game while I ran one final test.
[19:28] Because this is a super
complicated robot that took a year to build.
[19:31] But if you want to know what it feels like to
build an epic robot of your own, well, you're in
[19:36] luck with Hack Pack where you get a really cool
robot in a box delivered right to your door and it
[19:40] will work right away with no programming required,
unless you want to get creative, levelling up your
[19:45] robot's capabilities by tweaking the
code, which we make really easy to do.
[19:48] Like with this desktop lamp that has its own
personality or this plant tank that will drive
[19:52] itself around the house to find the perfect sunny
spot as well as letting you know when it needs water.
[19:57] But then if you're just getting started on your
journey of learning how to build anything you can
[20:01] dream up with Build Box, you get a really
fun mechanical toy each month where you build it
[20:05] alongside me and I teach you all
the cool physics that make it work.
[20:08] On top of that, each month your box has a chance
to contain the platinum ticket, and if you get it...
[20:14] ...then you're coming out to CrunchLabs
to build and play with my team for a day.
[20:17] So if you're a kid and you're looking for
something to put at the top of your Christmas list,
[20:21] or you're just looking to be the household hero by
giving it to someone else, head to CrunchLabs.com,
[20:26] where we're giving away two free boxes for our
holiday special, and where you'll find we finally
[20:31] completed our trilogy of creative engineering
subscription box options now ranging from ages 6
[20:36] to 106.
[20:36] And now that the game was over, it was time to
face Cristiano Ronaldo, the greatest soccer player
[20:42] of all time, a legend on the field, and
[20:44] - Oh my gosh, he's right here
tying his shoes right in front of me.
[20:46] - All of a sudden this was real.
[20:48] It was happening and I had to
show him that I meant business.
[20:51] - All right, Cristiano, I will bet you 5 million
subscribers that you cannot score on me in goal.
[20:58] I'll give you 3 tries even.
[21:00] - That I don't score?
[21:01] - Yeah, and you won't score.
[21:02] - OK.
[21:03] Let's go.
[21:04] - OK.
[21:05] - Now, of course I didn't think I was gonna stop
all of them, but considering my lifetime of soccer
[21:10] experience I wondered if I
had a shot at stopping one.
[21:13] I mean, he is Cristiano Ronaldo, but I've
been training my whole life for this moment.
[21:17] - Oh.
[21:18] Oh wow.
[21:19] Oh, that's not good.
[21:21] - OK, obviously I wasn't gonna
be able to block all of them.
[21:23] - I'm not even wearing gloves.
[21:26] - Or even 2.
[21:27] - That was like an inch gap.
[21:30] - OK.
[21:30] - But now,
[21:31] - Now I know your tells.
[21:33] - I had a shot at getting one
[21:34] Because having seen
Cristiano's form hitting both the left,
[21:39] and the right,
[21:40] I had a chance to study his body language to
figure out which direction he was going to...
[21:45] - Again, the same.
[21:47] - Really?
[21:48] - Yeah.
[21:49] - Oh wow!
[21:51] You even told me.
[21:53] That's disappointing.
[21:54] - One more?
[21:55] - No,
[21:56] I actually have something
else I want to show you over here.
[21:58] - It was time to introduce Ronaldo to my guest
of honor in front of half the Portugal national
[22:03] soccer team he brought over with him, no biggie.
[22:05] - All right, Cristiano, when I said you couldn't
score on me, I meant you couldn't score on my robot.
[22:11] - And I held for applause, as did my robot,
but Cristiano seemed less than impressed.
[22:17] - It looks big, huh?
[22:18] - Yeah, he's a little bigger than me.
[22:20] - Yeah.
[22:21] - You want to see how fast it moves?
[22:23] - Yes.
[22:23] - OK, Ian, we good?
[22:26] Let's show him.
[22:31] Do it one more time!
[22:36] - Very fast.
[22:36] - It's really fast?
[22:37] The robot is better than me.
[22:40] - Oh let's try.
[22:40] - Ronaldo was game.
[22:42] - Here we go.
[22:42] - I wanted to get started
pretty far away from the goalie.
[22:45] - You're too far away, get closer.
[22:46] - Oh yeah, I am still warming up.
[22:48] - All right, Cristiano, we are ready.
[22:49] - OK.
[22:50] - It was time for Ronaldo to
face some cold hard engineering.
[22:57] - Let me do that another one just to see.
[22:59] - And his first kick didn't offer him up any clues.
[23:01] - Do you have a strategy now?
[23:02] What do you think?
[23:03] - We need to... I don't know.
[23:05] Let, let me try again.
[23:09] - That was fast.
[23:10] - It will have to be force.
[23:17] - Oh!
[23:19] - So is he better than me?
[23:20] - Yes.
[23:21] - Ronaldo kept trying to go out at full force and
quickly realized this was not going to be an easy fight.
[23:27] - I like that you're stretching now.
[23:29] - Yeah, the beating's coming.
[23:32] - But the only thing taking a beating
[23:36] was Ronaldo's standing amongst his teammates.
[23:38] - Do you want to try?
[23:39] - Yeah if you don't score we will?
[23:40] - So I took a shot on my own.
[23:41] - If you keep going, you might tire him out.
[23:43] I don't know.
[23:46] I'm just kidding.
[23:48] Until he gently suggested I shut my mouth.
[23:51] Oh!
[23:52] - Which left quite an impression.
[23:54] - Wow, that would have broken a nose.
[23:56] - The goalie robot looked to be unbeatable, which
was a huge relief because when shipping the robot
[24:01] over here, one of the carriage rails got
slightly damaged, and this meant sometimes it would stop
[24:05] short of the goalpost on
kick's place to the right.
[24:08] But thankfully...
[24:10] it didn't seem to be an issue after all.
[24:12] - You think he could be on the Portuguese team.
[24:13] - Yes better than Diogo.
[24:17] - It seemed like his theory was that the
cameras were tracking his body to predict the ball
[24:22] direction before he kicked
it, so he ran a simple test.
[24:27] - Oh Panenka!
[24:31] The stutter!
[24:32] But then he seemed to have a new plan.
[24:33] - This ball has a sensor.
[24:34] It sees the center of the ball.
[24:37] - Because he stopped using his kicks to try and
beat the robot and started using his kicks to try and
[24:43] find a weakness.
[24:47] - I'm going to try something different now.
[24:50] - That had potential!
[24:52] - It's the little gap in the corner there.
[24:53] Got to try and put it there.
[24:57] I hit it here.
[24:58] - Oh OK, I'm getting nervous.
[25:00] - Let me try again.
[25:00] - OK, OK.
[25:02] - Last one.
[25:03] - Go to the top again.
[25:04] - That's what I'm going to do.
[25:06] - All right, ready when you are.
[25:33] - The funny thing about lifelong dreams is they
always involve a bunch of unexpected twists and
[25:38] turns on the pathway up the mountain that
often end up being some of the best moments.
[25:43] - This is some amazing stuff though.
[25:45] - And, and even when the view at the
top isn't exactly what you first pictured
[25:49] - Thank you, buddy really appreciate it.
[25:51] - And very good, very good evening.
[25:54] - it means you can now see a bunch more mountain
tops you could potentially climb next, but those
[25:59] will have to wait for another video.
[26:00] - Jeez, these NASA people...
[26:05] - This holiday season, if you want to have a ton of
