Day 1&2: Alex - atomisadev/cubert GitHub Wiki
Hey all, this is where I'll be documenting my progress on the design/fabrication portion of the build. My name is Alex, and I am really excited to get started!
Below is the rough proposal for the mechanical aspect of the build. This was the first step of the planning and is obviously very vague. But, here it is, to give you some context:
Design Process Overview
Structure
Lightweight PLA 3D printed see-through web-design cage encompasses the rubik's cube, with a hole in the center of each face for where the servo motors will go. There will be an armature piece on each face that directly connects from the servo output to the centerpiece of the rubik's cube face, either completely replacing the center piece or encompassing the center piece
Unique Adapters
An adapter will be designed and fabricated for the servo output, as well as an adapter for the centerpiece on each rubik's cube face. Purdue ECE did it by creating new center pieces that mounted to the rubik’s cube and also could mount to the armature.
Wire Routing
The cage will have sides to which all the wires will be fastened
Potential issue(s)
The main issue I'm foreseeing with this design is figuring out the adapters and figuring out a way to make the rubik's cube easily removable from the cage.
V0 Adapter
The first step for me was to design a temporary adapter that would serve as the connection from the servos that spin each side to the actual face of the Rubik's Cube. I'm currently using the Purdubiks machine as inspiration, with the idea being to create an adapter that directly interacts with the interior of the center dot. I'm using a random 3-D model of a speed cube for reference for now, as I don't actually own a Rubik's cube yet, but I'm really hoping that the kind person who modeled the cube modeled it true to life. Enough yap, this is what we're working with currently:
Bear in mind, this is just meant to be a proof of concept to me that my idea works. This will become much more refined once more details are finalized. but this is what we have for now.
