LEGO Cinnamon Hearts Candy Catapult

LEGO Cinnamon Hearts Candy Catapult

Kristal, can you get me a cinnamon heart? Can’t you just build a robot to do that
for you? Hey Everyone, Jason here. Last year LEGO released a new robotics programming
kit called the BOOST, and I finally found some time to build something with it. With February here and Valentine’s day coming
up, we had some cinnamon hearts around the house and I thought it would be a fun challenge
to try to build a catapult to launch them at us while we were sitting on the couch,
and as you saw in the introduction, it actually worked out surprisingly well. So, let’s take a look at how it works. There is a hopper at the top of the machine,
which has a hole at the bottom, so the cinnamon hearts can fall through onto the conveyor
belt, which is driven through these gears here from one of the internal motors of the
hub. And the conveyor belt transports the cinnamon
hearts into this channel, where they fall into a hole underneath the light sensor, and
the light sensor detects when a cinnamon heart is present to stop the conveyor belt so that,
in theory, you only get one cinnamon heart at a time. That hole is part of a shuttle that moves
back and forth, which is controlled through the external motor here. And the shuttle actually performs two tasks. The first is that it pushes the cinnamon heart
onto the catapult to load it up, and the second is that it launches the catapult when it retracts. And, hopefully I can find that later. The catapult actually works through the coordinated
effort of three separate mechanisms. The first are these elastic bands here, which actually store the energy used to fire the catapult. And we can see them in action if we just manually
fire it. The second is this lever here, which actually
pushes the catapult down and it’s driven from the other internal motor of the hub,
through these gears here, which gear it down enough to actually be able to do it. It actually takes quite a bit of force to
push the catapult down. And the third, of course, is the shuttle,
which holds the catapult down while the lever retracts, and then releases the catapult to
fire it. And we can see all that in action here. So when we put all that together, whenever
you want a cinnamon heart, you can just run the program and it will trigger the entire
sequence. Ah, I missed. I will be posting building instructions for
this model, hopefully within the next week, and you’ll be able to find those over at, as usual. I might also make a building video for this,
just so it’s a little more clear how it all goes together. All the pieces you need to build this come
in the BOOST, so if you have this set, you’ll be able to build it. Except for the cinnamon hearts of course,
and if you’re not a big fan of cinnamon hearts you can probably repurpose it for any
small candy. You might just have to change a few things,
like the hopper and maybe how the light is mounted, just to accommodate whatever you
put in it. I had a lot of fun building this model and
playing around with the BOOST, there’s a lot of things I like about it, and some things, not so much, but I’ll save that for another video. As always, thanks for watching, keep on building, and I’ll see you next time. Are you ready.
I’m ready. Again!
Okay. Hahaha. There was two. Okay, hold on.
So many cinnamon hearts. I know, we’ve got some issues right now. Did you get it?
I got it. It hurt my tooth.

  2. 0:43 how many takes did you do?

  3. Now make one for beer cans.

  4. As usual, really amazing!

  5. I’ve been trying to develop a model that can build minifigures for me😂, let’s just say it’s a long work in process, awesome video though

  6. Hey YouTube, you should add option, when i like the video so much I can add more than one like 😀 JK well done, please keep building and making videos. Thumps up!

  7. He was reading sariel's book!

  8. How did you get Renée Zellweger for this vid? (It's a joke)

  9. Hi there, awesome building and story too 😂👍

  10. "Hope I can find that later" lol

  11. Very cool. Looks like an actual factory machine

  12. Very nice model, but the best thing is your comedy!

  13. Suuuuure, you could just "get up" and "take the sweets out the bowl" but where's the fun in that

  14. your builds are amazing but the best part of your videos are always the scenes in the beginning!

  15. This is brilliant!

  16. Lol, impressive :)🐼👍

  17. I'm french and i don't have a good english but… It's a beautiful catapulte.
    You are crazy man it's just perfect. You are the boss of the lego

  18. That was the most casual catch I’ve ever seen

  19. Чувак ты просто ленивая задница !!!!! Блин я ТЕБЯ не понимаю , а так постройка вполне приколная , можно использовать как котопульту :3

  20. Jason: im too lazy to grab a cinnamon hart. I'm not to lazy to spend a couple of hours to develop and build a robot to transport them to me.

  21. Just awesome 👏👏👏😱😱😱

  22. Please keep doing Boost stuff please!

  23. That's brilliant!
    I take it that the way the whole unit shifts slightly every time it fires was a conscious design choice to give added challenge when trying to catch the candy? 🙂

  24. Can you build one to launch fries to my apartment from McDonald's? Actually, no. Best not.

  25. Is there a rapid fire feature?

  26. Never heard of this LEGO BOOST set, how new is it?

  27. I wonder how many try’s it took you before the cinnamon hearts actually landed in your mouth

  28. Funny how crystal tries and tries to catch the candy and Jason nails it on is first try.

  29. AN INFERIOR MACHINE! Can it launch a 90kg cinnamon heart 300 meters?

  30. Thats some REAL Fun 😉 I didn't expect the box to be as large and full as Mindstorms ! We love what you build, J & K ^^ Keep on !

  31. I'm definitely going to build this with my BOOST kit; looking forward to instructions!

  32. this is a great build but it would be much better if it was a trebuchet

  33. That’s awesome! Great work!

  34. Mindstorms?


    Lego's new Crappy Mindstorms™?

    well, they paid me for it, so yeah I guess

  35. I love your creations, but I love your videos more. 🙂

  36. Necessity is the mother of invention.

    In this case, the “necessity” is our couch potato time.

  37. great. now my fictitious kids are going to launch candy all over the freaking house.

  38. Very creative and fun contraption!

  39. I'd love a building video, please do one

  40. I absolutely LOVE your sense of humor that you put into these videos! It's half the reason I watch! Love it man! Keep it up! Easter next? 🙂

  41. Your work never fails to impress!

  42. inb4 you thinking of le sexy time, but the bae says: "can't you just build a robot to do that for you?"

  43. Look at this guy, and why for age old 7-12?

  44. Programming interface looks so, so bad. I know it's designed for kids to be able to use, but man does it kill it dead for me.

  45. Where does your inspiration come from to "invent" mechanism like theese?
    how much does it take fo finish something like those?

  46. Can you please do a tutorial for it ?😁😋😁


    Do you know Paul irl?

  48. The dude can build a Lego robot. But can't reach for candy…

    Love it

  49. Wow! Great video. We subbed your channel. Pls sub back .Thank you so much.

  50. I like that you are doing a skit at the start it was really good

  51. Are legos food safe?


  53. i like that you're reading sariel's book volume two

  54. How to build this machine? Super!

  55. 0:58 nice acting 😛

  56. do a working lego type writer

  57. *builds a robot to fling candy into his mouth instead of putting the bowl next to him

  58. That's impress I've. 🙂

  59. Very creative video, and funny intro!

  60. Hah, this is awesome!

  61. +jkbrickworks hey, what was that book you were reading on the couch??

  62. I love your vids keep up the good work

  63. You're great creative engineer, but how can it help people in life? is it usable?

  64. Have you’re LEGO set!!!!!!!

  65. 0:59 it didn't even land in his mouth!

  66. Hey I have about 100 lbs of mixed LEGO parts from around 2005-2012 that I’m looking to sell, I also have a decent sized tub of figures and another tub of around 200 instruction manuals. Anyone know of someone that’ll buy some of it? I’m looking for about $10 per pound, but am willing to drop that if you’ll buy enough of them

  67. I built it

  68. If you don't really care for any candy, I bet a stud would fit in there just fine.

  69. If you make a building video for this model, can you also include the programming on the app? I noticed a few buttons to set it up but hard to see from that angle which buttons and the proper order.

  70. He makes the best Lego creatins!

  71. Gawd I hurt my füt

  72. Create more machines of lego boost obs +1 subscribe

  73. That looks cool! I have lego boost, but I lost the pieces for it! My mom is nice and will let me get a new one once my sister gets her paycheck! And i will build that!

  74. You are a damn genius!!!

  75. Upload more plz if possible

  76. Those catches looked fake

  77. You have Lego WeDo 2.0?

  79. Hi can you connect two external motors to boost?

  80. Eres increíble muy increíble Te felicito
