+:::
+
+## Description
+
+This project is an end-to-end automated solver. It uses a smartphone camera to scan all six faces of the Rubik's Cube. The mobile application processes the images to identify the color configuration and calculates the optimal solution using the Kociemba algorithm. The resulting move sequence is transmitted to an STM32 microcontroller, which executes the physical rotations using six NEMA 17 stepper motors.
+
+## Motivation
+
+The goal is to integrate high-level software (Computer Vision and Pathfinding) with low-level hardware control. By using a smartphone as the sensor, I can leverage its high-resolution camera and processing power to simplify the hardware setup while creating a seamless user experience where a simple scan leads to a physical solution.
+
+## Architecture
+
+The system operates in three main stages:
+
+1. Vision Layer: Smartphone app captures and parses the cube's state.
+
+2. Communication Layer: Data is sent via UART (Serial) or Bluetooth/Wi-Fi to the STM32.
+
+3. Execution Layer: STM32 coordinates six A4988 drivers to perform the moves.
