How to Build a Robot

Two motors, one sensor, and a machine that roams — in plain English.

Always wanted to build a robot but bounced off the jargon? This 72-page guide walks you from zero to a finished two-wheel rover that drives itself and dodges obstacles. Every part is explained piece by piece — Arduino, motor driver, sensors, power — with illustrations, a full wiring diagram, and complete working code explained block by block.

Inside: the parts and what they cost, kits vs building from scratch, 3 budget builds (under $50, ~$100, ~$200), the step-by-step first build, line-following and remote-control upgrades, a 12-row troubleshooting table, and battery and soldering safety. PDF ebook, instant download after checkout.
