Homemade Robots is a beginnerâ??s guide to building a wide range of mobile, autonomous bots using common household materials. Its 10 creative and easy-to-follow projects are designed to maximize fun with minimal effortâ??no electronics experience necessary!

From the teetering Wobbler to the rolling Barreller, each bot is self-driving and has a unique personality. Thereâ??s the aptly named Inchworm Bot made of aluminum rulers; Buffer, a street sweeper-like bot that polishes the floor as it walks; and Sail Bot, which changes direction based on the wind.

Randy Sarafanâ??s hacker approach to sculptural robotics will appeal to builders of all ages. Youâ??ll learn basic electronics, get comfortable with tools and mechanical systems, and gain the confidence to explore further on your own. A wide world of robots is yours to discover, and Homemade Robots is the perfect starting point.
