Beginning Robotics with Raspberry Pi and Arduino: Using Python and OpenCV

Build a Working Robot, Not Just a Theory

Most introductions to robotics either drown you in abstract concepts or hand you a prebuilt kit with no real learning. This book takes a different path. It guides you through building a small mobile robot from the ground up, using the Raspberry Pi for high-level control and an Arduino for real-time tasks. By the final chapter, you’ll have a rolling platform that can follow lines, avoid edges, and track a ball with a camera.

What You’ll Work With

The project begins with setting up a Raspberry Pi, installing Raspbian, and getting comfortable with Python. From there, you’ll learn how to read sensors, control LEDs, drive DC motors, and communicate between the Pi and Arduino over serial. The book introduces the GPIO interface, explains why an Arduino is useful for analog input and precise timing, and shows how to combine both boards into one cohesive system.

From Chassis to Software

Assembly is covered in practical terms: choosing a chassis material, mounting electronics, wiring motor drivers, and attaching infrared sensors. The code examples grow with the hardware, moving from simple Python scripts to a PID controller that smooths out line-following behavior. Even if your parts differ slightly from the book’s bill of materials, the concepts transfer to most hobbyist components.

Add Computer Vision with OpenCV

The final stretch introduces OpenCV on the Raspberry Pi. You’ll select a compatible camera, capture images, detect blobs and colors, and build a ball-chasing robot. It’s a satisfying combination of software and hardware that demonstrates how a little computer vision can make a robot feel much smarter.

Who Is This For?

The book assumes no deep robotics background, but it does move quickly. Some familiarity with basic programming or electronics will make the experience smoother. Hobbyists, makers, students, and educators looking for a structured, hands-on introduction to robotics will find the progression clear and motivating. Each chapter closes with suggestions for further reading, so you can deepen any topic that catches your interest.
