LEGO TECHNIC is designed to allow builders to create more advanced models with moving parts, like those built with LEGO MINDSTORMS. The Unofficial LEGO TECHNIC Idea Book: Vehicles offers hundreds of ideas and examples for building mechanisms with TECHNIC. This volume focuses on vehicles that can drive, turn, move things, and go backwards. The book is color throughout, with little to no text accompanying its diagrams. It begins by teaching readers about tires, rotation speed, and how to build a simple car with a motor, then demonstrates more complex actions, such as how to use differential gears; make a car turn or move items; add car suspension with rubber bands or springs; and go backwards and forwards and switch rotational directions. The Unofficial LEGO TECHNIC Idea Books are for anyone who wants to create a moving masterpiece, as well as those who want to make original robots with MINDSTORMS. It can also be used to demonstrate how machines work and to experience the fun of mechanics.
