Homemade Robots is a hands-on beginner’s guide for using common household materials to build a wide range of mobile, autonomous bots. Creative and easy-to-follow, all 10 projects are designed for maximum fun, with relatively minimal effort – no electronics experience necessary!

From the walking Wobbler to the rolling Barreler, each bot is a self-driving mechanical wonder with a unique personality. There’s the ingenious Inchworm Bot, made out of aluminum rulers, and Skitter, a street sweeper-like bot that buffs the floors as it moves. There are bots that press their own switches to change direction, and a Sail Bot that adjusts its pathway based on the wind. But for all their differences, every one of the book’s bot projects has the following things in common:

  • They are quick and easy to build with readily available materials
  • They are easy to understand and don’t require a microcontroller or computer code
  • They are expandable, allowing you to mod them with more complex controls later

The author’s hacker approach to sculptural robotics will appeal to builders of all ages, who will learn basic electronics, become comfortable with tools and familiar with mechanical systems, and gain the confidence to further explore the wide world of robotics waiting to be discovered.
