DIY cupcake machine (Arduino cooking robot)

I have built the DIY machine (robot) which makes delicious cupcakes. Everything is controlled with Arduino. The two stepper motors are responsible for moving cupcake from dough station to the cooking station (microwave oven) to the topping station. At first the machine was not working properly, but I managed to adjust everything to make it work.

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

[@Skyentific]

Glad you enjoyed it! Thank you!

[@MultiUroX]

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

[@ConstantijnC]

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! 😊

[@Skyentific]

Very good point!!! Thank you a lot! And happy holidays!

[@ericlotze7724]

I think someone made a good "open source paste extruder". And i think the person making that "OpenPNP" thing also did peanut butter. and Happy Holidays ! Make a festive (tiny, non-homogenized) cupcake for freinds/family!

[@ericlotze7724]

And outside of the frosting pumps, everything else workedd great! Some minor tweaks and it should be near perfect.

[@donaldviszneki8251]

If the compressibility of the syringe contents is variable, maybe a force sensor is required along with some control software to be confident that the proper amount is extruded. In the 3d printing world, the term "linear advance" refers to compensation for static (non-variable) nonlinear extrusion volume, and it seems to work well for most people who bother setting it up, but I suspect they find their linear advance settings aren't as good if they change materials or other operating parametera.

[@DNIWEDONNOE]

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

[@contrerasisaac]

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

[@wallyhulea219]

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.

[@DudleyToolwright]

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

[@Jayang5540]

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

[@ZaufaneKlipy]

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

[@jpippar]

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

[@AdityaPrakash-kt3rf]

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!

[@ElectricGears]

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.

[@rdyer8764]

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!

[@ericlotze7724]

Could mix it with the drink machine idea i had, and just have a l o n g line that can make nearly anything. Maybe make it in "segments" that can be assembled on site? Either way a great thing to bring to a school/makerspace/makerfair for even food. "dinner and a (robotic) show" as they say!

[@ericlotze7724]

Also could put it in a food truck like " @ 1.5x playback everything - thank me later " was thinking.

Решена она мерзкими стабилизаторами и эмульгаторами. Лучше пусть будет неприглядно, но сохранит домашний рецепт.

[@SergejKolmogorov]

@@eugene-d я говорил про физическую формовку, а не изменение ингредиентов. Например больше давления и впрыскивание материалов в массу печенья, а не брызганья ими с высоты.

Thank you good job

[@brandonbreault6243]

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!

[@vengion1379]

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

[@Skyentific]

Agree! :))))

[@morkovija]

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 =)

[@MrGatlin98]

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

[@iloverobotics113]

[@ericlotze7724]

Like an "Easy Bake Oven" but way cooler!

[@ericlotze7724]

I always thought they were like a motorized "conveyor belt oven" like some pizza places have, but they were simply a heated tube, this is MUCH more like what i was thinking up as a kid, amazing build !

[@sungjinrobotec9041]

very nice ^^ fun!

[@PhG1961]

Wonderfull !

[@vmened]

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

[@nikimminen]

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.

Also you can install rotating reflector into microowen chamber

[@wpirkl]

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

[@satibel]

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

[@lesto12321]

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

[@prokradima]

Кулинарной индустрии брошен дерзкий вызов!

[@DeanRockne]

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.

[@l3d-3dmaker58]

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

[@BeefIngot]

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)

[@almostanengineer]

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

[@louisvandendriessche534]

nice want to do somthing like this for a longtime

[@jayroefrengarciaespinoza6902]

great, can you tell me please how do you did it?, code, material, 3d models,etc. i´m a mechatronic engineer and i want to know more

[@alekseikhudoshin4481]

13:28 One scientist one cup.

[@mashurshalehin4972]

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

[@Skyentific]

Yes, this could help!

[@ingusmant]

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

[@DanielSMatthews]

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.

[@Skyentific]

Great idea!

[@synchro-dentally1965]

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?

[@Skyentific]

Thank you. If you made them proportional, this can create standing wave inside microwave, and this will make the heating extremely inhomogeneous.

[@jones8185]

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

[@dervideogucker8734]

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.

[@Skyentific]

Great question. The answer: this power supply is not only for Arduino. It also powers: 1. fans in microwave; 2. relays; 3. silicon guns.

[@dervideogucker8734]

@@Skyentific I supposed something like that ;) Thank you for your answer and have an amazing holiday!

I do't know if you remember, but in a previous video of yours I mentioned that I preferred Cartesian robots to robotic arms because they are easier to develop. You have just proved my point. Or can you make a cupcake maker using those robotic arms from the other videos? 🤔

[@rodstartube]

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

[@frohlmusic]

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.

[@Skyentific]

Здрасте. Этот стакан напечатан в petg, а он держит более высокую температуру, чем PLA. Плюс бумажный стаканчик, наверно немного изолировал температуру. Я сам очень боялся что он расплавится, но он все выдержал достойно :)))

[@user-fy2uy1yr7r]

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

[@michaegi4717]

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.

[@Vlad0304UA]

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!

[@Skyentific]

Spasibo!

[@ericlotze7724]

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!

[@andrethetechnerd6407]

What long linear rails are you using? From Igus?

[@chrisBruner]

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.

[@Skyentific]

Thank you. I would also prefer heater oven now. The advantage of microwave: for microwave cooking time is around 60 seconds, for heater oven around 16 minutes.

[@chrisBruner]

@@Skyentific I figured that was why you went with microwave. Maybe make an assembly line system, with long oven, :) New cupcake every 16 minutes.

[@konserv]

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

[@Skyentific]

Of course!

[@robertj9511]

13:15 😂🤣😂 Nice work!

[@excitedbox5705]

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.

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!)

[@ericlotze7724]

Most projects have been called "bar bots" and have cocktail ingredients, but they can use anything really, could even make one for a fancy coffee (all the flavor syrups + an espresso and coffee machine "in line" ) or a soup!

[@ericlotze7724]

Most use peristalic and/or "srynge + leadscrew" pumps i think? That or an airpump + sealed bottle.

[@brettd5884]

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.

[@brettd5884]

Someone is reading the EDN article.... It was highlighted in their weekly newsletter. B)

[@ericlotze7724]

8:40 This could be relevant to microwave (or X-Ray ;) lol ) sterilization of things. I was looking into "x-ray food irradiation" and i never thought of a mechanism like that for "sealing" the container? I was thinking some sort of complex "air lock" like system, but simply having it "be the bottom" works well it seems!
