Build a Pantograph Drawing Robot with Arduino Uno – Precision Motion, Scaled Drawings

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a robotic arm that traces your drawings, then scales them up four times larger on paper. This pantograph drawing robot uses two servo motors at the shoulder joints of a parallelogram linkage – precisely the same geometry used in industrial plotters and miniature CNC machines. You’ll code smooth, synchronized motion and watch your digital designs come to life as physical ink-on-paper artwork.

What You'll Build

You’ll assemble a breadboard circuit around an Arduino Uno, wire two MG90S servos as pantograph shoulders, and mount acrylic rods to create the drawing linkage. The 0.96-inch OLED displays live joint angles, and two potentiometers let you manually calibrate endpoints. By the end, you’ll have a working robot that holds a pen and replicates any line art you define in code.

What You'll Learn

• Coordinate two servo motors in a parallel kinematic chain to produce smooth, scaled pen movements
• Implement inverse kinematics for a pantograph, converting drawing coordinates into servo angles
• Read analog values from potentiometers and map them to servo positions for real-time calibration
• Use an OLED display and Arduino libraries to create a live diagnostic interface for debugging motion paths

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate project is perfect for CBSE Class 11–12 students exploring mechatronics for science exhibitions, B.Tech ECE/EEE undergraduates tackling kinematics coursework, and participants in the Smart India Hackathon or ATL Tinkering Labs. If you’ve built basic Arduino circuits and are ready to combine mechanics with code, this kit bridges theory and a tangible, demo-ready robot.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
