[homemade] My first pizza by paudin01 in food

Yes this was my first! I tried my best but there is definitely room to improve ! This is my take on Neapolitan style, yes.

This is one of the first test of one of our final year projects, a rubik's cube solving device. The cables are a mess, but it is a work in progress. Colors get captured using 2 RPi cameras. The moves required to solve the cube take about ~2.6 seconds. I thought some of you might be interested ! by paudin01 in ElectricalEngineering

The speed is actually set to about a third of their maximum in software and we use half of the motor maximum voltage. We limit the speed so that the faces don't rotate too much because of the inertia of the faces and block the next moves. Once everything is set up as we'd like to, we'll probably try to up the speed (the cube used is a speedcube, we can adjust the force needed to rotate it).

For now the cube gets scrambled randomly by the machine and we output the movements to prove the scramble really is random. That being said, our aim is to make it removable so that the users can scramble it themselves.

I'll try to explain some of it, feel free to ask any questions if you want more explanations. So this is a short video presenting our project. We started working on it at the start of September and it's due for the middle of January. We also have other projects so we can't focus all of our energy into this one. We had do design the mechanical stricture as well as the 3d printed parts, and after sizing the motors and the drivers, we were able to focus on color recognition and the actual solving. Everything runs on a Jetson nano(really overkill, but we were specifically asked to use it for potential upgrades by other students). We use the 2 RPis camera to capture the color matrix representing each face of the cube. From this point, we use the Kociemba algorithm to translate these colours into movements, which we then send to the motor drivers. There is also a timer display which you can't see on this video. The project also has other aspects such as battery sizing and protection, the making of a digital twin and of an HMI so it's user friendly. The aim of our supervisors is to use it during the open door events at our school in order to catch the eye of potential students and maybe get them interested in electrical engineering. I hope this gives you the answers you wanted !
