Abstract—This paper presents the research, design, and fabrication of a sand drawing robot capable of rendering detailed images on sandy surfaces. The robot integrates a robust mechanical system optimized for navigation and stability on deformable terrain, addressing challenges unique to sandy environments. Advanced control algorithms are developed for precise movement and drawing execution, ensuring consistent line quality and pattern accuracy. A user-friendly interface allows for custom image input, which is processed through sophisticated path-planning algorithms to generate executable instructions for the robot. Experimental results demonstrate the robot's ability to accurately reproduce complex designs, highlighting its potential applications in interactive art installations and educational settings. This work contributes to the field of robotics in Vietnam and worldwide by enhancing the precision and reliability of autonomous robots operating in dynamic and unstructured environments.

Keywords—control algorithms, image processing, mechanical design, path planning, robotic art, sand drawing robot
