Wall Drawing Robot

Açıklama

Wall Drawing Robot (XY Plotter) – ESP32 CNC-Based System This is not just another 3D model. This project presents a full-scale wall drawing robot concept — a vertical XY plotter using a suspended V-frame gondola system, capable of turning almost any wall into a drawing surface. Powered by an ESP32-based CNC controller, the system operates as a simplified two-axis CNC machine, converting vector graphics into real-world drawings with high precision. How It Works Dual-motor XY system (top-mounted) V-shaped suspended gondola structure Gravity-stabilized drawing head G-code driven motion (CNC principle) ESP32 controller for motion control and communication The system translates XY coordinates into cable or belt movement and executes drawing paths in real time, similar to large-format wall plotters. What You Get 3D printable mechanical parts Assembly concept Demonstration of drawing capability Important This release includes mechanical design only. To make the system fully functional, additional components and development are required: Motion control firmware Calibration parameters Kinematics conversion (XY to cable length mapping) Electronics setup and tuning If you have experience with CNC or plotter systems, you will recognize that this is typically the most challenging part of the build. Why This Project Is Interesting Enables large-scale wall drawing Suitable for creative automation or mural applications Low-cost CNC concept using a lightweight structure ESP32 allows wireless…
