A fun coding-free beginner's guide to basic robotics. The book's 16 simple and entertaining robots can all be built using only common materials, basic tools, and some basic electronic components. Readers will use a computer fan and a cake tin to make a nervous bot that vibrates across the floor, build a rolling barrel robot using a paint can and servo motor, and make an unpredictable rolling bot from an over-sized tennis ball and a scrubbing brush, plus plenty more.
