Pi 5 Robotic Painter Arm
Pi 5 Robotic Painter Arm: Build a Precision Drawing Robot with Inverse Kinematics
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Program a 4-DOF robotic arm to draw intricate patterns, logos, or your own digital art using waypoint-based trajectories on Raspberry Pi 5. This kit merges mechanical assembly with computational geometry, teaching inverse kinematics for precise pen positioning—exactly what you need to prototype a pick-and-place artist or a CNC pattern generator.
What You'll Build
You’ll assemble a fully functional robotic painter that translates digital coordinates into physical strokes. Load a vector design, and the arm plots it on paper with sub-millimeter accuracy, controlled by your own Python scripts. It’s an AI-ready platform you can extend with computer vision to draw what it sees.
What You'll Learn
- Inverse kinematics for 4-DOF arm trajectory planning
- Servo control via PCA9685 and pulse-width modulation
- Sensorless homing and calibration for drawing repeatability
- Integrating Pi 5 with NVMe storage for real-time path data logging

Who This Kit Is For
Ideal for CBSE Class 11–12 students diving into mechatronics, B.Tech ECE freshers preparing for a robotics internship, or Smart India Hackathon teams prototyping an automated drawing system. Also perfect for ATL labs and university makerspaces at VIT, NIT, and BITS Pilani exploring inverse kinematics.
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.
What if I get stuck during the build?
The AI companion provides immediate visual guidance; if you still need help, our WhatsApp chat connects you to a human expert who has built this exact arm.
Can I use this arm to draw from image inputs?
Yes, the NVMe SSD gives you enough headroom to add a camera and OpenCV later. The AI companion includes pointers for extending the project that way.
Does the kit include the pen or drawing paper?
The pen holder is included; you supply your own pen and paper. We recommend a fine-tip marker for crisp line quality.
How precise is the drawing?
With proper calibration, the arm achieves sub-millimeter accuracy and repeatable arcs—enough for intricate mandalas, PCB layout marking, or calligraphy experiments.
Waypoint-based trajectory on Pi 5 controls 4-DOF arm to draw patterns — inverse kinematics for precise pen positioning.
