What if you could have fresh pasta, cooked and ready, with the push of a button?
I learned the other day that Pancakebot is a real device. It prints and cooks custom pancakes from your photos . It’s on sale for $299, which is pricey, but a pretty amazing price for what it does. Today on the beach, in my usual hungry daydreaming, I wondered how difficult it would be to build the same thing for fresh pasta. Below is my short conceptualization of what it would actually take to build something for that.
Concept: Robot that makes and cooks fresh strand pasta on command.
Budget: $300.
Steps:
- Robot takes ingredients (water, flour, eggs?, salt?) and mixes them into a dough.
- Robot rolls dough out into a thin sheet.
- Robot cuts dough into strands of a specified width.
- Robot pushes strands into pot of boiling water and cooks to al-dente.
- Robot removes and drains pasta.
For the purposes of this bot, we’ll confine the robot to a single shape of pasta, and ignore saucing and anything after the cooking of the pasta.
Let’s work this up and see how we might go about completing each of these five steps.
Trigger and centralized control: We could probably start the process using an API hooked up to an arduino, which would manage the whole process.
Cost: An off-brand Arduino and accompanying electronics might run us $40-50. We’ll budget $50.
1. Ingredient Mixing: The easiest way to build this would have the human pre-portion the incredients. If that happens, then we could probably do the mixing using a $25-30 simple mixer on Amazon. We could control this step using either an Arduino with some hardware modifications to the mixer, or some sort of smart-home electrical outlet (Maybe another $20).
Cost: Mixer plus smart-home or Arduino control. We’ll budget $50.
2. Rolling the dough: Traditional mechanical pasta-rollers can be had on Amazon for around $18. Automating this should be a matter of hooking some type of motor up to the crank on it.
Cost: Let’s budget $40 for the pasta roller plus whatever motor units we need.
3. Cutting the dough: My intuition on this is to use something like a bench knife ($5), hooked up to a servo motor (< $10).
Cost: Knife and motor should cost around $15.
4. Cooking the pasta: This is one of the more complex parts. For heating the water, I think some sort of hot plate should suffice. The problem is, very hot elements are not something I want to mess around with. This is the one area where I’d feel uncomfortable digging into the electrical innards to make it work programatically.
Cost: Not sure. Hot plates are available at just about any price-point, but for safety and heat-control I’d probably go for something in the $30 range. I’d also need a pot and a collander. This $16 collander looks promising and there are plenty of nice pots for $20 or less. Let’s budget $70 for this step.
5. Getting the pasta in and out of the pot: For getting the pasta in and out of the water, I’d use some sort of rig tied to the collander. The pasta cooks in a pot in the collander, and when it’s near done, the rig lifts the strainer out of the pot and into a ceramic bowl.
Cost: I’m not quite sure how I’d do this, but I think $30 should be plenty for this step.
We’ll also have to figure out some way of moving the dough from the mixer to the pasta-maker, and from the pasta-maker to the pot.
So, where does this leave us? Most of these ideas are totally doable. Getting the cooking time and temperature right, and getting the steps to work together would take some time and error. The only big challenge is finding a safe way to heat the pasta on command.
In this simple brainstorm I budgeted about $255 for the whole shebang. If we can figure out those safety issues, this should be buildable.
