Robotic Drawing Arm

The Robotic Drawing Arm project is a programmable, servo-driven mechanical system capable of sketching basic shapes and patterns on paper. Built using lightweight materials, servo motors, and controlled via an Arduino microcontroller, this project combines principles of mechanical design, electronics, and embedded programming.

Key Features:

Utilizes two to three servo motors for X-Y (and optional Z) axis movement

Custom arm linkages designed for coordinated drawing motion

Controlled via Arduino UNO with basic C++-style code to manage servo angles

User-defined patterns or pre-programmed shapes (e.g. square, circle, initials)

Calibrated for repeatable and relatively accurate pen placement

Skills Applied:

Arduino programming to control movement timing and angles

Mechanical design for stable arm movement and pen grip

Debugging motion errors through iterative testing and angle calibration

This project served as an excellent introduction to robot kinematics, precision control, and integrated systems. It enhanced both my coding confidence and my ability to bridge physical hardware with software logic, skills essential in robotics and automation.
