DIY cupcake machine (Arduino cooking robot) 

Perhaps the most joyful thing I've seen today. Thank you for being so educational, yet enjoyable.

I experimented with 3D printing peanut butter on my channel and what I learned was that the syringe has to be filled up with absolutely no air bubbles. Since air is much more compressible than water, the compression to extrude from the syringe will cause it to leak afterwards. Retracting the plunger of the syringe after extruding also helped against leakage. Thanks for sharing and happy holidays! 😊

"ohh, shit!", me: "yeah! Literally!".

This is one of my favorite channels, thank you for bringing it to the world!

I'm subscribed to so many high-quality channels, I struggle to add new subscriptions due to time constraints. But you've earned a spot on that list for me with this one video. I'm glad this was recommended to me!

Now try to use a robot arm to place the cup cake base and remove the product. You got a automatic cup cake production line :D

yes! robotic applications are very valuable for your channel, I know that it takes longer but it is worth it, good job!

There is so much hard work in this project! Well done!

I love your idea of feeding the microwave from below, with the rotating platform being the door. Would love to automate some of my own bachelor chow that way.

A truly amazing project! This is some startup level stuff! If u make a 2nd finished version of this, this could be a great thing! Also I shared this with my relative who is in the food industry. I probably shouldn't have shared this because now they r going to ask me to make this for them! Great video! Waiting for whats next!

I'm glad that I subscribed to you way before while I've been learning about robotics.

A week ago I was asked repeatedly what I wanted for Christmas. My answer was “nothing, I already have everything I want”. Boy was I wrong!

This project deserves a big thumbs up. Very nicely done and I appreciate seeing the failures and much as the successes.

Very interesting and funny project! Looking forward for more of such kind :)

Awesome looking forward to version 2 !

Классный проект! Надо было подглядеть как в пищевой промышленности решена эта проблема красивой формовки ингредиентов.

great project! and cupcakes look delicious!

this is awesome !

As soon as he said "There are several things which can go wrong with this Microwave" I'm like "um yeaaah!" :D

Intersting, thanks for sharing!

Awesome project! thanks for sharing :-)

man you are genius! you over-engineered the hell out of it 😂😂

Best RU-vid channel and you deserve all the cupcakes

Great to see you back 😊 Well done a successful cupcake machine, wishing you a Happy Xmas time 😊🎁😊

Definitely your most worthwhile endeavor so far! :)) With some fine tuning it's going to be a beast of a machine! May I suggest that you reverse the feed on all 3 tubes after dispensing each material. That may help with the dripping of unwanted material on the machine. Also pick a batter mix without chunks. Your next thing should be a cake decorating machine. There are already some out there, but once you master this task, you can combine it to create even more beautiful cupcakes! Great stuff. Every geeks dream to combine tech and junk food. Yumm! Maybe you could insert the cream topping dispenser down INTO the cupcake and make one like I used to buy at the store with cream filling!

Brilliant!!

Soo cool . Really a good projekt!

very very nice!! your videos really inspire me!

Awwwww. This project is awesome ! With few tweaks someone might start a cupcake business with this :D Fresh cupcake on demand

Great video!!! 👍👍👍

Super vidéo merci beaucoup !

You and Ben from Applied Science should team up to build the ultimate cookie perfection machine

Yummy 😋😋😋😋 Your automation is great

Another way of evening out the energy some microwave ovens use is by pointing the magnatron at a metal fan. That might help since you have such a small cooking chamber. You might also add a cooling fan station before the toppings.

The dough shooting out had me laughing. I can literally see how easily it could be implemented, great work.

Thank you good job

0:42 - Cheburashka as a symbol of happiness )))

You are a true genius ! Now we need a robot that eats the cake. 👍

Nice, subscribed! Congrats on the HaD post.

Great video!!

Superb!

17:21 That simply looks divine, If somebody would say it's from three michelin kitchen, I wouldn't even question it.

Побольше бы таких проектов!

Absolutely love it! I've been playing around with interfacing Arduino and ODrive for a huge project I have. Tons of fun and a lot of learning. Is there any chance you could make a video that really walks through the setup, further than the OdriveArduinoTest? Such as not only how to send commands for position, velocity, current but also how to read information such as encoder position, voltage, amperage, etc? Love your content and I am so glad you are doing this full-time and showing us more!

You are genius

very nice ^^ fun!

keep awesome ❤️

Wonderfull !

Like an "Easy Bake Oven" but way cooler!

Робот який готує кекс ,а далі вечерю,сніданок ,обід.супер)

Кулинарной индустрии брошен дерзкий вызов!

Had this idea long time ago - on site automatic food preparation. Imagine fast food joint but without any people, fully autonomous, In a van form factor, parked outside somewhere. You're welcome to use the idea =)

Food printing is still underexplored in the "Makertube" space. It's hard to get something working, but seems to be very popular.

I would love to see a workshop tour to see your setup and where you build these projects.

Wow I didn't know you work a couple of km away! 🤩

Интересная игрушка, даже можно попробовать сделать что-то похожее в серию и на продажу.. НО, всё оборудование пищевой промышленности должно свободно мыться, т.е. быть как минимум брызгозащищенным. Скорее всего для этого электроника должна быть в отдельном шкафу, а весь привод жен быть гидравлическим или хорошо изолирован от влаги. К сожалению очень непросто в такой схеме добиться влагозащиты. А идея прикольная и даже работает. Поздравляю!

Приветствую! Удивительно что напечатанный стакан не расплавился, так как тесто достаточно сильно разогревается в микроволновке во время приготовления. Я так однажды по дурости решил корпус, который печатался 24 часа, помыть от клея и просушить в сушильном шкафу настроенном на 50С°. Корпус пришлось потом выбросить.

Neat. They did really similar machine in my workplace last year. It also did use a microwave magnetron to cook the dought. Search for "cupcake mini factory vtt" and you can find some info on it.

hi you could try some rf gaskets on the bottom tray or some aluminum tape between the panels of the box

man, I love your channel! I would so love to build robots with servos and actuators, maybe even a servo 3d printer but they're so expensive! I would love to find a cheap alternative to driving servos for making inexpensive robot arms or other devices, but servos are prohibitively expensive and even "cheap" stuff like Odrive is $100+ so you'd end up spending upwards of $400 for two servos

nice want to do somthing like this for a longtime

For the dispensers, perhaps a vat with a linear auger would work better. You could have a larger opening for chunks and add a retraction step to the auger to cut off flow more precisely.

Adding a top cooling fan, I guess would be just enough

Great video. I would have used a heater oven, (loaded from the bottom like yours), I also suggest you move the base while the cupcake is turning to get a spiral. Impressive work.

Very cool but now I want a cupcake!

Сразу вспоминается "Красная жара" с шварцем ))))

Also you can pull backward surgine for avoid puddles on the rails

you could use a servo to rotate the cupcake and make any shape you want with the topping since you'd have 2 axis.

You should retract the plunger on the toppings to create negative pressure. Also adding a fan to cool the cupcake will help the toppings not melt. The microwave leakage could be from the hole for the motor under the cup. A normal microwave has another sheet of metal which yours lacks. The simple solution would be fixing a screen around the entire machine to keep people from getting their hands caught in the conveyor as well and that way you can shield the waves making it out of the microwave.

Impressive result. At the beinnging I was concerned about the miceo wave oven. But with all your security measures it seems to be fairly safe. For liquid topings you might use something like the "soda fountain machine" from the channel "the q". I guess their machine is not good solution for soda (because of the CO2-gas from the soda will push the soda out) but for your topings it should be a clean solution.

Nice one! I also started building a 6 DoF robot arm now - you might enjoy watching it :)

Почти готовый вендинговый аппарат получился. Супер!!

Also you can install rotating reflector into microowen chamber

13:15 😂🤣😂 Nice work!

It looks awesome 😎 Does the enclosure of microwave connected to the ground?

11:49 this reminds me some hard days in the bathroom

Really nice project !!! For the microwave, should you have a little oven ? much safe even if it's hotter. You could add a quality control at the end line with jetson nano :D For the topping, maybe some electro valves would avoir leaking :P

You could use a peltier cell to cool the surface so the toppings wont melt

You made the "Cupcake...in a cup" from Wall-E

I would really encourage you to put a conductive gasket between the platform and the microwave oven chamber. If you don’t have good electrical contact all the way around, leakage could be life changing (eyeball contents cook like egg-whites!)

Thank you for this Video :) I have one question: Why is the power supply for the Arduino so big? I would suppose it's the smallest power sink in your assembly.

epfl :D i like this! :)

I think you need a blast chiller in between the microwave and topping stage to cook the cup cale

when i see the tiny cupcake: "SUCCESS!!"

I was very suprised to see the coop prix-garantie in your hands xD do you live in switzerland? :D

3D printers have the same problem of dropping down unwanted material. They (try to) solve this by pulling back the material for maybe 4mm. So you might try to pull back the "pistons" for just a few millimeters after each usage by 2 or 3 or 4mm maybe. For the next cupcake you need to push the material by these extra millmeters down. But it is difficult with such liquid materials like the ones you need. You would need some tweaking and it might not really help. Maybe you get an air pocket on top between your "material" and the "piston"... Well, you could try it. If it helps, it's great. If it makes things worse, sorry, don't use it again. ... But the microwave is the really scary part of that machine... try at least to fix the microwave leakage, maybe it is in the ventilation holes, maybe at some other gap.

That's really cool! I'm only speculating but would having the microwave chamber's dimensions be proportional to the output wavelength help with the leakage?

Are the holes in the side of the microwave case small enough to stop the microwaves wavelengths? (Im not even sure that made scientific sense but I think theres a reason microwave windows use mesh)

Can you add a randomised surface to the inside of the microwave to act as a diffusing reflector? I think that the problem is the modes for such simple geometry are not very complex so you get that patterning of the energy distribution.

Have you considered making one of those "Modular Drink Machines" with a conveyor and a module for each syrup/alchohol/soda?

Hello, nice video! Do you have a link from the nema 17 Motor with a trapezoidal thread Nut?

I wonder if using a normal heat element (Nichrome wire) would help with cooking and get rid of the radiation danger

I'm glad you're using a microwave leakage detector. I like this project! As darrin husmann wrote> Perhaps the most joyful thing I've seen today. . Microwave leakage: You should check out how microwave ovens "seal" the cooking cavity around the door (which apparently doesn't seem to actually seal the cavity). These depend on half-wave shorted stubs to simulate a cavity "seal". Here's a very brief description: www.edn.com/your-microwave-oven-needs-a-choke-flange/ . Microwave Hotspots: Many ovens include a "stirrer" to constantly move standing waves inside the cavity (standing waves are the reason hotspots exist.) The hotspots still exist, but they are never in any particular place long enough to be a problem. The stirrer is located near where the microwaves are injected into the cavity.

do you have a link to the stepper motors with lead screws integrated?

What long linear rails are you using? From Igus?

13:28 One scientist one cup.

ah yes, the microwave death box

Maybe to improve your design, you could add little pans that catch dropping toppings and retract when the cupcake is in the right place

I think it would be better if you moved the dough feed step to the left of the microwave step

10:22 I THINK (don't trust me 100% i'm no expert lol) metal mesh (like what is used in the window) works? Either way distance like you did works fine, and uses no parts!
