LEGO® INSPIRATION FOR ALL AGES
This book in the LEGO Technic™ Non-Electric Models series features 141 motor-free devices for you to build and operate. Each project includes full-color photographs from multiple angles and illustrated Technic parts to help you follow along. The models range from basic mechanisms that showcase the power of gears and rotation to moving vehicles that demonstrate linear, oscillating, rotary, and reciprocating motion.
The Technic models in Simple Machines require no electric elements or sensors. Instead, they operate with cranks, chains, cams, rack-and-pinion gears, rubber bands, weights, and flywheels. As you explore these projects and develop your building skills, you’ll be inspired to create your own mechanical marvels.
This Technic guide is part of a series, and the brainchild of master builder Yoshihito Isogawa. Each book in the series is filled with vibrant photos of Isogawa's unique non-electric models, which will fire up the imaginations of LEGO builders of all ages.
Imagine. Create. Invent. Now, what will you build?
