+# Mobile Drawing Robot with Automatic Canvas Calibration
+A mobile drawing robot that reproduces digital images on a physical canvas using automatic border detection.
+
+:::info
+
+**Author**: Denis-Dumitru Sarca \
+**Github Project Link**: https://github.com/UPB-PMRust-Students/acs-project-2026-Denis-bit
+
+:::
+## Description
+
+This project consists of a mobile robot capable of drawing digital images on a physical surface. The robot receives a processed drawing path from a PC and follows the generated trajectory using a differential drive system.
+The drawing area is delimited using a black border placed around the canvas. The robot uses IR reflective sensors to detect this border and estimate the available drawing surface. Based on the detected canvas dimensions, the input image is scaled so that it fits inside the physical workspace.
+The robot uses two powered wheels for movement and a third caster wheel for mechanical support. A servo motor controls the pen mechanism, allowing the system to lift or lower the pen while following the drawing path.
+
+## Motivation
+
+Thought it would be a fun way to start my journey in embedded development. I also find it useful in different scenarios, since it has the automatic drawing surface detection.
+
+## Architecture
+The system is divided into two main parts: the PC application and the embedded firmware running on the STM32 board.
+The PC application is responsible for image processing. It loads the input image, converts it into a simplified drawing path and scales the result according to the canvas dimensions detected by the robot. The generated path is then sent to the microcontroller through a USB serial connection.
+The STM32 Nucleo-U545RE-Q board receives movement commands and controls the hardware modules. It drives the two DC motors through a motor driver, reads encoder feedback for position estimation, reads the IR sensors for black border detection and controls the servo motor used for lifting and lowering the pen.
