   # webcube Rubik's cube assistant on Flask webapp. This webapp accepts the six faces of your cube and gives you the voice instructions as a response. Demo -> [Link](https://www.linkedin.com/posts/yash-indane-aa6534179_machinelearning-flask-python-activity-6805902901546901507-dN6M) ## Requirements This webapp requires a lot of extra modules and packages to be downloaded, It is recommanded to follow this order : ``` $ yum install python3 -y $ yum install gcc-c++ -y $ yum install python3-devel -y $ pip3 install flask $ pip3 install Pillow $ pip3 install numpy $ pip3 install joblib $ pip3 install scikit-learn $ pip3 install scikit-build $ pip3 install opencv-python $ yum install opencv opencv-devel opencv-python -y $ pip3 install kociemba ``` ## Usage Navigate to `http://<IP>:<PORT>/input`. This webapp runs on port no. `85` by default, but can be changed in the `app.py` file. To use take edge to edge and centred pics of the cube. Start with `Red` face with the `White` face down, and take pictures in the order `Red -> Green -> Orange -> Blue -> Yellow -> White`. After this click `get solution`. While listening to the instructions face the `Red` centred face with the `White` centred face down.  ## Running the container ``` $ sudo docker run -dit -p <PORT>:85 --name <NAME> yashindane/webcube:v1 ``` ## Running the container using podman ``` $ sudo podman run -dit -p <PORT>:85 --name <NAME> docker.io/yashindane/webcube:v1 ``` ## Arm64v8 machines ``` $ sudo docker run --platform linux/arm64/v8 -dit -p <PORT>:85 --name <NAME> yashindane/webcube:linux-arm64v8 ``` Code for arm64v8 version -> [link](https://github.com/YashIndane/webcube-arm64v8) ## Working The six images of six faces have there respective `data_uri`, which are submitted by a form when you click `get solution`. This `data_uri` are converted to images and saved. Next the function `order` from `order_image.py` renames and creates new images (format example face_0.png to face_5.png), according to images that have central tile colour matching in the order `yellow -> green -> red -> white -> blue -> orange`. Naming images in this order is required for the cube to be solved. A cubestring is formed after predicting the tile colours and getting there respective notations. ```py colour_mappings = { "red": "F", "green": "R", "blue": "L", "yellow": "U", "white": "D", "orange": "B" } ``` The cubestring is passed to the `kociemba.solve()` function, which return a string containing instructions for solving the cube. Kociemba is a Python/C implementation of Herbert Kociemba's Two-Phase algorithm for solving Rubik's Cube. Read full documentation of Kociemba here -> [Link](https://pypi.org/project/kociemba/) the instructions are decoded to human voice instructions. This instructions are then written to the `output.js` file, which outputs this instructions as voice. ## Building docker image build docker image by -> `$ docker build -t <username>/<repo-name>:<version>` I have also uploded already build image for this webapp on Docker Hub -> [Link](https://hub.docker.com/repository/docker/yashindane/webcube) ## deploying the image in Kubernetes create a deployment by -> `$ kubectl create deployment <deploy-name> --image <username>/<repo-name>:<version> ` Scale the deployment if necessary and create a service by -> `$ kubectl expose deployment <deploy-name> --port=85 --name=<service-name> --type=LoadBalancer` ## Prerequisite browser settings ### 1. Remove chrome managed by your organisation (Optional) Visit this link -> [link](https://www.youtube.com/watch?v=DaLaWChdyug) ### 2. Edit chrome flags for camera access Navigate to `chrome://flags/#unsafely-treat-insecure-origin-as-secure` on chrome browser and add `http://<IP>:<PORT>` inside `Insecure origins treated as secure box` and click enable and reload the chrome page. After usage just remove the entry and click disable.
