Fans off Wallace and Gromit will all remember two things about the franchise: the sort of creepy — but mostly delightful — stop-motion animation and Wallace’s Rube Goldberg-esque inventions. YouTuber Gregulations was inspired by Wallace’s Autochef breakfast-cooking contraption and decided to build his own robot to prepare morning meals.
Gregulations wanted his Autochef-9000 to churn out traditional full British breakfasts consisted of buttered toast, eggs, beans, and sausage. That was an ambitious goal, because each of those foods requires several steps to prepare. Gregulations’ solution was to, essentially, create one large machine that contains several smaller CNC machines. Each one is distinct and tailored to suit a particular food. In total — if you add up all of the different sections — this is a 12-axis CNC machine.
The Autochef-9000’s central controller is an Arduino Mega 2560 board. But even with the power and number of pins available, that wouldn’t have been able to handle everything. So it divvies out some tasks to Arduino UNO Rev3 boards.
As you would expect, this takes quite a lot of heat to cook everything. That’s why the Autochef-9000 contains several electric heating elements, which the Arduinos control via relays.
Users can order food using a touchscreen menu system or a smartphone interface. Autochef-9000 will then whir to life. It will open and heat a tin of beans, grab and heat a sausage, hard boil an egg, and toast and then butter bread fed from a magazine. Finally, it will deposit all of those items onto a plate.
There is a lot going on inside of this machine and Gregulations breezes past a lot of the technical details, but it is a joy to see in action. And unlike Wallace’s inventions, this one hasn’t caused any serious disasters (yet).
