World Record Domino Robot (100k dominoes in 24hrs)

  • 0:00 - 0:01
    This is Dom.
  • 0:01 - 0:03
    He's a friendly little robot
  • 0:03 - 0:05
    that's super good at only one thing.
  • 0:05 - 0:07
    Setting up a butt-ton of dominos
  • 0:07 - 0:08
    really really fast.
  • 0:08 - 0:10
    It's taken five years to get to this point
  • 0:10 - 0:12
    but according to our initial tests,
  • 0:12 - 0:14
    we have hopes that he might be more than
  • 0:14 - 0:16
    ten times faster than the fastest human.
  • 0:16 - 0:18
    So today we're gonna put him to the test
  • 0:18 - 0:20
    going head to head against he world's
  • 0:20 - 0:21
    foremost domino expert,
  • 0:21 - 0:23
    who unfortunately is a mere human.
  • 0:23 - 0:24
    Then we're gonna attempt a
  • 0:24 - 0:26
    Guinness world record and he's gonna try
  • 0:26 - 0:28
    and fill this entire warehouse
  • 0:28 - 0:29
    with a mural
  • 0:29 - 0:30
    of a hundred thousand dominos.
  • 0:30 - 0:32
    And for context, setting up a domino mural
  • 0:32 - 0:35
    that size would take a team of seven
  • 0:35 - 0:36
    skilled builders one full week.
  • 0:36 - 0:38
    Dom here, is gonna attempt to do it
  • 0:38 - 0:40
    by himself in 24 hours.
  • 0:40 - 0:42
    Now I know what you're thinking,
  • 0:42 - 0:43
    "Big whoop Mark,"
  • 0:43 - 0:45
    because as a kid you might have had a toy
  • 0:45 - 0:46
    that looked like this.
  • 0:46 - 0:47
    Or even this custom robot
  • 0:47 - 0:49
    KiwiCo made me that can drop
  • 0:49 - 0:50
    twenty dominos in a row.
  • 0:50 - 0:52
    So isn't a bit overkill to utilize
  • 0:52 - 0:53
    an autonomous robot,
  • 0:53 - 0:55
    a half mile of Hot Wheels tracks,
  • 0:55 - 0:57
    and a high speed robotic arm?
  • 0:57 - 0:58
    And I get it because our designs
  • 0:58 - 1:00
    look like this where we were just trying
  • 1:00 - 1:02
    to hack a Roomba when we first tried to
  • 1:02 - 1:03
    tackle this problem
  • 1:03 - 1:04
    exactly five years ago.
  • 1:04 - 1:08
    But then pesky details with scale arise
  • 1:08 - 1:10
    like for starters, just how much
  • 1:10 - 1:11
    100,000 dominos is.
  • 1:11 - 1:14
    So the robot will need to come and reload
  • 1:14 - 1:16
    at least 1,000 times.
  • 1:16 - 1:18
    But how exactly do you reload it?
  • 1:18 - 1:20
    And how would it know exactly where
  • 1:20 - 1:22
    to drop each domino and what color
  • 1:22 - 1:23
    it should be?
  • 1:23 - 1:25
    And how do you make it so reliable,
  • 1:25 - 1:26
    that it doesn't screw up once
  • 1:26 - 1:29
    in a 100,000 drops of a domino?
  • 1:29 - 1:31
    A system to reliably tackle issues
  • 1:31 - 1:33
    at scales like this is just going to be
  • 1:33 - 1:34
    inherently super complex.
  • 1:34 - 1:36
    Like ten times more complex
  • 1:36 - 1:39
    than my automatic bullseye dartboard,
  • 1:39 - 1:40
    which to this point was probably the most
  • 1:40 - 1:42
    complicated build on my channel.
  • 1:42 - 1:43
    So after failing off and on
  • 1:43 - 1:44
    for three years,
  • 1:44 - 1:46
    I was doing a Q and A at Makerfaire
  • 1:46 - 1:48
    and I told the crowd if anyone wanted
  • 1:48 - 1:50
    to help me with the brutal challenge
  • 1:50 - 1:51
    to hit me up afterwards.
  • 1:51 - 1:52
    And to my absolute delight,
  • 1:52 - 1:53
    two freshmen from Stanford
  • 1:53 - 1:55
    and a software engineer from
  • 1:55 - 1:56
    The Bay Area,
  • 1:56 - 1:57
    all took me up on the challenge.
  • 1:57 - 1:59
    So I hired them and two years later,
  • 1:59 - 2:00
    here we were.
  • 2:00 - 2:02
    Now before I show you how it all works,
  • 2:02 - 2:04
    I just wanted to put him in a head to head
  • 2:04 - 2:06
    competition to see how good he really was.
  • 2:06 - 2:08
    And for that we need the undisputed
  • 2:08 - 2:09
    heavyweight champion on YouTube
  • 2:09 - 2:11
    for all things dominos,
  • 2:11 - 2:12
    Lily Hevesh.
  • 2:12 - 2:15
    Lily, you are known on YouTube as
  • 2:15 - 2:16
    The Queen of Dominos right?
  • 2:16 - 2:18
    People do call me The Domino Queen.
  • 2:18 - 2:19
    And for very good reason,
  • 2:19 - 2:21
    with over 1.2 billion views on
  • 2:21 - 2:22
    her channel,
  • 2:22 - 2:24
    you've almost certainly seen
  • 2:24 - 2:25
    one of her incredible creations
  • 2:25 - 2:27
    over her 12 years on the platform.
  • 2:27 - 2:28
    She's so good,
  • 2:28 - 2:30
    she's even got her own line of dominos
  • 2:30 - 2:31
    you can buy in stores.
  • 2:31 - 2:33
    Ok, so here's the challenge Lily.
  • 2:33 - 2:35
    I want you to set up like 300 dominos
  • 2:35 - 2:37
    right now and let's see how long it takes
  • 2:37 - 2:38
    a human to do that.
  • 2:38 - 2:39
    Ok.
  • 2:40 - 2:41
    Clock starts,
  • 2:42 - 2:43
    Now.
  • 2:44 - 2:46
    I got to do two hands.
  • 2:47 - 2:48
    If you need me, Lily,
  • 2:48 - 2:50
    just sitting here reading my newspaper.
  • 2:50 - 2:53
    For you kids at home a newspaper is like
  • 2:53 - 2:55
    a boring ipad made from trees.
  • 2:57 - 3:00
    That's actually pretty fast.
  • 3:02 - 3:03
    Oh no.
  • 3:04 - 3:07
    Disaster, the foibles of being human.
  • 3:07 - 3:10
    Ok Lily are ready for this?
  • 3:10 - 3:11
    No.
  • 3:11 - 3:12
    I've seen enough.
  • 3:12 - 3:13
    (Failure to whistle)
  • 3:13 - 3:15
    I actually don't know how to whistle.
  • 3:15 - 3:18
    This, is the Dominator.
  • 3:18 - 3:21
    Oh my god
  • 3:21 - 3:23
    Wow
  • 3:23 - 3:24
    I love the eyes.
  • 3:24 - 3:26
    A good set of googly eyes will go
  • 3:26 - 3:28
    a long ways.
  • 3:28 - 3:31
    Ok boy, let em down.
  • 3:31 - 3:33
    I suck at dominos, Lily,
  • 3:33 - 3:36
    but i'm good at engineering which means
  • 3:36 - 3:38
    I'm actually really good at dominos.
  • 3:39 - 3:41
    We even showed off
  • 3:41 - 3:43
    the Dominator doubled-stacked
  • 3:43 - 3:44
    the middle row for you.
  • 3:44 - 3:45
    That is impressive,
  • 3:45 - 3:47
    that is seriously impressive.
  • 3:47 - 3:49
    This technique of laying down
  • 3:49 - 3:50
    a tile of 300 dominos at once
  • 3:50 - 3:52
    was really the key that helped us crack
  • 3:52 - 3:54
    the scale and reliability issues.
  • 3:54 - 3:56
    And its probably my favorite part about
  • 3:56 - 3:57
    the Dominator,
  • 3:57 - 3:58
    besides his wiggly tail of course.
  • 3:58 - 4:00
    Here's Josh to explain more.
  • 4:00 - 4:02
    So these 3D printed funnels here,
  • 4:02 - 4:03
    which allow us to drop all 300 dominos
  • 4:03 - 4:04
    all at once.
  • 4:04 - 4:06
    And the mechanism that drops those into
  • 4:06 - 4:08
    the top of this tray
  • 4:08 - 4:09
    we'll show that in just a second.
  • 4:09 - 4:11
    And if we remove these funnels here
  • 4:11 - 4:12
    we can see that the dominos are
  • 4:12 - 4:14
    precisely placed in their locations.
  • 4:14 - 4:16
    This allows us to place 300 dominos
  • 4:16 - 4:18
    exactly where we want them all at once.
  • 4:18 - 4:20
    And they don't fall out because of what we
  • 4:20 - 4:22
    call the Connect 4 mechanism under here.
  • 4:22 - 4:23
    But if we trigger the servo,
  • 4:23 - 4:25
    then it slides that Connect 4 tray over
  • 4:25 - 4:27
    and drops them all at once
  • 4:27 - 4:29
    making for some gratuitous, beautiful
  • 4:29 - 4:31
    slow-mo shots.
  • 4:43 - 4:44
    And so while this looks very cool,
  • 4:44 - 4:46
    obviously dropping from that height
  • 4:46 - 4:47
    wouldn't be effective.
  • 4:47 - 4:49
    So we lower the whole platform down
  • 4:49 - 4:50
    on this ball screw.
  • 4:50 - 4:52
    Then set them right on the floor,
  • 4:52 - 4:54
    which turned out to be incredibly reliable
  • 4:54 - 4:56
    So Dom took the W in round one.
  • 4:56 - 4:58
    But now it's time for the endurance round.
  • 4:58 - 5:01
    Ok, first one to 10,000 dominos wins.
  • 5:01 - 5:03
    Lily, you ready?
  • 5:03 - 5:04
    I'm ready.
  • 5:04 - 5:05
    Dominator, you ready?
  • 5:07 - 5:08
    Start
  • 5:13 - 5:14
    Oh my god
  • 5:14 - 5:15
    Wow
  • 5:15 - 5:16
    I aready failed.
  • 5:16 - 5:17
    That's great.
  • 5:24 - 5:25
    And to Lily's credit,
  • 5:25 - 5:27
    she was actually insanely fast.
  • 5:27 - 5:31
    Just not, you know, robot fast.
  • 5:31 - 5:32
    So unfair,
  • 5:32 - 5:33
    so unfair.
  • 5:33 - 5:35
    On top of that she had to handle a very
  • 5:35 - 5:38
    large distraction with emotional maturity
  • 5:38 - 5:39
    of a 9 year old.
  • 5:40 - 5:43
    Yep, I think I'm doing pretty good.
  • 5:47 - 5:49
    You're doing very good for a human
  • 5:49 - 5:50
    I'll give you that.
  • 5:51 - 5:52
    Oh no
  • 5:52 - 5:53
    Woah
  • 5:57 - 6:00
    No what, no what Lily?
  • 6:00 - 6:01
    Get out, Get out
  • 6:02 - 6:05
    Aaaaaahhh
  • 6:05 - 6:06
    That feels so much faster than
  • 6:06 - 6:08
    it probably looks.
  • 6:08 - 6:09
    How's Lily doing?
  • 6:09 - 6:10
    Tired.
  • 6:10 - 6:12
    And so while Lily's output slowed down
  • 6:12 - 6:12
    considerably,
  • 6:12 - 6:14
    Dom's did not.
  • 6:14 - 6:16
    And I should mention we sometimes call him
  • 6:16 - 6:17
    Dom but that's just short for his
  • 6:17 - 6:18
    legal birth name,
  • 6:18 - 6:19
    which as noted before,
  • 6:19 - 6:20
    is Dominator.
  • 6:20 - 6:21
    Cause you know like
  • 6:21 - 6:22
    domino
  • 6:22 - 6:23
    Dominator
  • 6:23 - 6:25
    whatever, it all works.
  • 6:25 - 6:27
    I'm gonna head to the bathroom.
  • 6:27 - 6:30
    Oh, Lily has to go to the bathroom.
  • 6:30 - 6:31
    I'm human, right?
  • 6:31 - 6:34
    Dominator do you have to go
  • 6:34 - 6:35
    to the bathroom?
  • 6:35 - 6:36
    Didn't think so.
  • 6:40 - 6:42
    9,000 perfectly laid dominos in a little
  • 6:42 - 6:43
    over two hours.
  • 6:43 - 6:45
    Actually 9,000 and 1,
  • 6:45 - 6:48
    we got a bonus domino out there in
  • 6:48 - 6:49
    the middle of this field.
  • 6:49 - 6:51
    May or may not have been on purpose,
  • 6:51 - 6:54
    but now we can say that it's over 9,000.
  • 6:54 - 6:55
    It was a pretty clear result
  • 6:55 - 6:56
    and Lily, of course, was gracious
  • 6:56 - 6:58
    in her defeat to the machine overlords.
  • 6:58 - 7:00
    So all that was left to do now,
  • 7:00 - 7:02
    was to knock em down.
  • 7:06 - 7:08
    Yes! That was satisfying.
  • 7:08 - 7:10
    So we went head to head with
  • 7:10 - 7:12
    the world's foremost domino expert
  • 7:12 - 7:13
    and came out on top.
  • 7:13 - 7:15
    And now it's time for the real challenge.
  • 7:15 - 7:16
    To attempt a Guinness World Record,
  • 7:16 - 7:18
    and see how quickly we can fill
  • 7:18 - 7:20
    this entire room with a mural,
  • 7:20 - 7:22
    of over 100,000 dominos.
  • 7:22 - 7:23
    Alright buddy,
  • 7:23 - 7:24
    you got the game plan,
  • 7:24 - 7:26
    now you just got to get out there
  • 7:26 - 7:27
    and execute.
  • 7:28 - 7:30
    Godspeed little fella, Godspeed.
  • 7:37 - 7:41
    300 dominos down, 102,000 left to go.
  • 8:05 - 8:06
    So we're about six hours in
  • 8:06 - 8:08
    but more importantly,
  • 8:08 - 8:10
    We just got our first Goomba.
  • 8:10 - 8:11
    It's beautiful.
  • 8:11 - 8:14
    Back to work Dom.
  • 8:15 - 8:17
    And the best part of working
  • 8:17 - 8:18
    really hard for a few years,
  • 8:18 - 8:19
    is that the last 24 hours
  • 8:19 - 8:21
    are super relaxing.
  • 8:24 - 8:26
    And with that tile placed,
  • 8:26 - 8:28
    we are officially half way done.
  • 8:28 - 8:31
    With over 50,000 dominos put down,
  • 8:31 - 8:33
    and just a little over 12 hours.
  • 8:33 - 8:36
    And Dom, woah easy boy,
  • 8:36 - 8:39
    just showing no signs of slowing down.
  • 8:39 - 8:40
    So this is a good point
  • 8:40 - 8:42
    to explain the rest of the robotics system
  • 8:42 - 8:43
    It all starts over here
  • 8:43 - 8:45
    with the loading station that
  • 8:45 - 8:46
    Josh and John Luke spent a lot
  • 8:46 - 8:47
    of time optimizing.
  • 8:47 - 8:48
    The dominos are loaded by color
  • 8:48 - 8:50
    on these conveyer belts
  • 8:50 - 8:51
    and then a Kuka robot arm
  • 8:51 - 8:53
    grabs them and places them in one of
  • 8:53 - 8:55
    300 loading shoots made from 2.7 miles
  • 8:55 - 8:57
    worth of Hot Wheels tracks.
  • 8:57 - 8:58
    And you could load Dom directly
  • 8:58 - 8:59
    with the robot arm,
  • 8:59 - 9:01
    but this is much faster because he doesn't
  • 9:01 - 9:02
    have to wait,
  • 9:02 - 9:03
    he just comes in here to the
  • 9:03 - 9:05
    docking station and the lower
  • 9:05 - 9:06
    platform slides over so the bottem
  • 9:06 - 9:08
    layer of 300 dominos gets loaded up
  • 9:08 - 9:09
    all at once.
  • 9:09 - 9:11
    And we also had a back up loading system
  • 9:11 - 9:12
    using a tray just incase at any point
  • 9:12 - 9:14
    the robot arm wasn't working.
  • 9:14 - 9:15
    Besides the Hot Wheels tracks,
  • 9:15 - 9:17
    there's a ton of 3D printed parts
  • 9:17 - 9:19
    throughout the build that we either
  • 9:19 - 9:20
    printed ourselves or, if we were in
  • 9:20 - 9:22
    a pinch, my friends at MatterHackers
  • 9:22 - 9:23
    helped us out.
  • 9:23 - 9:24
    So that's the loader,
  • 9:24 - 9:26
    now how about the Dominator himself?
  • 9:26 - 9:27
    How does Dom know exactly where to go
  • 9:27 - 9:29
    in the room to drop a domino?
  • 9:29 - 9:31
    So we preprogramed the route for
  • 9:31 - 9:32
    all 102,000 dominos.
  • 9:32 - 9:34
    So the robot knows exactly where to go
  • 9:34 - 9:35
    right from the start.
  • 9:35 - 9:36
    Then as we're driving around,
  • 9:36 - 9:38
    we use these indoor GPS sensors
  • 9:38 - 9:40
    to track the position of the robot
  • 9:40 - 9:41
    so it knows roughly where it is
  • 9:41 - 9:43
    and then as we get closer the place
  • 9:43 - 9:44
    where the dominos need to drop,
  • 9:44 - 9:46
    we use these IR cameras that are
  • 9:46 - 9:47
    tracking markers on the ground to make
  • 9:47 - 9:48
    sure the robot lines up perfectly
  • 9:48 - 9:49
    every single time.
  • 9:49 - 9:51
    So the vision from the beginning was that
  • 9:51 - 9:52
    we could set Dom up
  • 9:52 - 9:53
    we could turn off the lights and leave,
  • 9:53 - 9:54
    and come back the next morning
  • 9:54 - 9:56
    and you've got like a full field
  • 9:56 - 9:57
    of dominos set up.
  • 9:57 - 9:57
    He could work all night in the dark
  • 9:57 - 9:58
    just fine.
  • 9:58 - 9:59
    Alright now how bout these
  • 9:59 - 10:00
    super cool wheels?
  • 10:00 - 10:02
    So these are called omni-wheels
  • 10:02 - 10:03
    and they're awesome because they let you
  • 10:03 - 10:04
    translate it any direction you want.
  • 10:04 - 10:06
    So this is way better than like your car
  • 10:06 - 10:08
    where if you need to move a little bit
  • 10:08 - 10:09
    to the left or right,
  • 10:09 - 10:11
    you have to make like a five point turn.
  • 10:11 - 10:12
    So with these guys you can move any
  • 10:12 - 10:14
    direction you want to adjust for small
  • 10:14 - 10:15
    corrections in the placement
  • 10:15 - 10:15
    of the dominos.
  • 10:15 - 10:17
    These wheels are powered by these
  • 10:17 - 10:19
    clear path, brushless DC server motors.
  • 10:19 - 10:20
    These are like the gold standard in terms
  • 10:20 - 10:21
    of speed and accuracy.
  • 10:21 - 10:23
    And they allow us to slide the robot
  • 10:23 - 10:24
    around by even just a couple millimeters
  • 10:24 - 10:25
    a time,
  • 10:25 - 10:27
    which is super useful when we're trying
  • 10:27 - 10:28
    to make real fine adjustments for placing
  • 10:28 - 10:28
    the dominos down.
  • 10:28 - 10:31
    Now obviously that's just the uppermost
  • 10:31 - 10:32
    tip of the iceberg tip.
  • 10:32 - 10:35
    But Dom's brain is over 14,000 lines
  • 10:35 - 10:36
    of code all from scratch.
  • 10:36 - 10:38
    So if you want to go way deeper into
  • 10:38 - 10:39
    the technical details I'll
  • 10:39 - 10:40
    put a link in the video's description,
  • 10:40 - 10:42
    where I'll just put it all in one spot.
  • 10:42 - 10:44
    Now back to finishing the second half.
  • 11:14 - 11:16
    So the Dominator has been running
  • 11:16 - 11:18
    just under 24 hours.
  • 11:18 - 11:21
    And this is a bit of a momentous tile here
  • 11:24 - 11:26
    It's a me Mario.
  • 11:32 - 11:36
    102,300 dominos are on the floor
  • 11:36 - 11:37
    succesfully.
  • 11:37 - 11:39
    This is the last 300.
  • 11:39 - 11:41
    I think this is a moment.
  • 11:41 - 11:43
    You guys get back over here.
  • 11:43 - 11:46
    Josh and Alex, let's observe it.
  • 11:46 - 11:49
    Don't blow this Dom, you got it buddy
  • 11:49 - 11:50
    finish strong.
  • 12:00 - 12:01
    We got it.
  • 12:01 - 12:04
    Just over 24 hours,
  • 12:04 - 12:06
    to lay all the dominos.
  • 12:06 - 12:07
    Gentlemen
  • 12:08 - 12:11
    It feels really fulfilling as an engineer
  • 12:11 - 12:13
    to see the design prosses yield results
  • 12:13 - 12:14
    like this.
  • 12:14 - 12:15
    And speaking of the engineering
  • 12:15 - 12:16
    design prosses,
  • 12:16 - 12:18
    my month long creative engineering course
  • 12:18 - 12:20
    where I teach this process,
  • 12:20 - 12:21
    and where you watch me make three builds
  • 12:21 - 12:23
    from scratch, and you make
  • 12:23 - 12:24
    three creative builds of your own.
  • 12:24 - 12:26
    Is once again open for enrollment for
  • 12:26 - 12:28
    a bonus Summer session right now.
  • 12:28 - 12:29
    So go to
  • 12:29 - 12:30
    monthly.com/markrober
  • 12:30 - 12:32
    or use the link in the video description.
  • 12:32 - 12:33
    And I'll see you in class.
  • 12:33 - 12:35
    So now with everything set up,
  • 12:35 - 12:37
    the final step was to knock em down.
  • 12:37 - 12:39
    You can see John loading in the Mario
  • 12:39 - 12:40
    pipes because they were going to be our
  • 12:40 - 12:41
    trigger mechanism.
  • 12:41 - 12:42
    The way that works is we've got four
  • 12:42 - 12:44
    Hot Wheels cars glued to the bottom of
  • 12:44 - 12:46
    this platform that rides in these
  • 12:46 - 12:48
    parallel Hot Wheels tracks.
  • 12:48 - 12:50
    Then you slap a green sliding shell on top,
  • 12:50 - 12:51
    and a motor at the end
  • 12:51 - 12:53
    pulls the cart along the tracks with
  • 12:53 - 12:53
    a string.
  • 12:53 - 12:55
    Then the shell contacts the lever arm
  • 12:55 - 12:56
    at each pipe like this,
  • 12:56 - 12:58
    which causes them to roll forward
  • 12:58 - 13:00
    down the ramp hopefully into the dominos.
  • 13:00 - 13:01
    Ok now I'm nervous.
  • 13:02 - 13:05
    I wasn't nervous, now I'm nervous.
  • 13:05 - 13:06
    OK
  • 13:06 - 13:07
    3
  • 13:07 - 13:08
    2
  • 13:08 - 13:09
    1
  • 13:09 - 13:10
    Go
  • 13:15 - 13:16
    Yes! Two!
  • 13:17 - 13:18
    Three!
  • 13:19 - 13:21
    Four!
  • 13:21 - 13:22
    Five!
  • 13:29 - 13:30
    Oh my gosh
  • 13:42 - 13:45
    Got em wooo!
  • 13:45 - 13:46
    Yes!
  • 13:46 - 13:48
    Awesome!
  • 13:49 - 13:50
    Holy cow!
  • 13:51 - 13:54
    Wooooaaah!
  • 13:54 - 13:56
    Oh my gosh
  • 13:57 - 13:59
    And in the end Dom was 50 times faster
  • 13:59 - 14:01
    than the skilled domino builder
  • 14:01 - 14:02
    and he got himself a world record
  • 14:02 - 14:03
    to show for it.
  • 14:03 - 14:05
    Although to be fair to us organisms,
  • 14:05 - 14:07
    It was in the non-human category.
  • 14:07 - 14:08
    And at that point after five years,
  • 14:08 - 14:10
    we were just so relieved to be done,
  • 14:10 - 14:11
    we got a little carried away carried away
  • 14:11 - 14:13
    celebrating the champ with
  • 14:13 - 14:14
    an appropriate sendoff.
  • 14:23 - 14:25
    Six year old me would be so stoked
  • 14:25 - 14:27
    to know that I would eventually build
  • 14:27 - 14:29
    a robot that could set up all the dominos
  • 14:29 - 14:29
    for me.
  • 14:29 - 14:31
    So if you want the same feeling of making
  • 14:31 - 14:33
    things with your hands to do cool things,
  • 14:33 - 14:35
    but you don't want to wait 35 years.
  • 14:35 - 14:37
    Then my friends at KiwiCo have got
  • 14:37 - 14:38
    the answer.
  • 14:38 - 14:41
    In fact, this is an actual mini version
  • 14:41 - 14:43
    of the Dom I designed together with them
  • 14:43 - 14:44
    just for this video.
  • 14:44 - 14:48
    I mean how awesome and adorable is that.
  • 14:48 - 14:49
    He's like the protégé.
  • 14:49 - 14:50
    The Dom Jr.
  • 14:50 - 14:52
    They got an incredible team of designers
  • 14:52 - 14:54
    that work on each project and honestly
  • 14:54 - 14:56
    if I wasn't making YouTube videos
  • 14:56 - 14:57
    I think I would apply to be on their team.
  • 14:57 - 15:00
    Then all the concepts are contested
  • 15:00 - 15:01
    and then its delivered right to your door
  • 15:01 - 15:02
    every month,
  • 15:02 - 15:04
    so you can foster your creativity
  • 15:04 - 15:05
    and make your abilities in a fun
  • 15:05 - 15:06
    and natural way.
  • 15:06 - 15:08
    So for example this domino machine box,
  • 15:08 - 15:09
    inside you've got all the supplies
  • 15:09 - 15:11
    you need to put it together.
  • 15:11 - 15:12
    You've got simple instructions.
  • 15:12 - 15:14
    And then a booklet with more info
  • 15:14 - 15:16
    like a Q and A with someone you might know.
  • 15:16 - 15:18
    And this is the tinker crate line
  • 15:18 - 15:19
    But they've got eight different
  • 15:19 - 15:21
    subscription lines each catering to
  • 15:21 - 15:23
    a different age group and topic.
  • 15:23 - 15:24
    So if you want to support my channel
  • 15:24 - 15:25
    and feed your brain while having
  • 15:25 - 15:26
    fun at the same time,
  • 15:26 - 15:30
    go to kiwico.com/roberdomino
  • 15:30 - 15:32
    or use the link in the video description
  • 15:32 - 15:33
    to get an excusive offer.
  • 15:33 - 15:35
    so thanks to KiwiCo for being so great
  • 15:35 - 15:36
    to work with, thanks to Dom
  • 15:36 - 15:39
    and Dom Jr. for just dominating,
  • 15:39 - 15:41
    and of course thanks to you for watching.
  • 15:41 - 15:42
    What do we do now?
  • 15:42 - 15:44
    We're about to clean it up.
  • 15:44 - 15:48
    Oh there we go, a cleanup robot.
