This second volume of The LEGO Power Functions Idea Book, Cars and Contraptions, showcases small projects to build with LEGO Technic gears, motors, gadgets, and other moving elements. You ll find hundreds of clever, buildable mechanisms, each one demonstrating a key building technique or mechanical principle. You ll learn to build four-wheel drive cars, adorable walking bots, steerable tanks, robotic inchworms, and cars that can follow the edge of a table! Each model includes a list of required parts and colorful photographs that guide you through the build without the need for step-by-step instructions. As you build, you ll explore the principles of gear systems, power translation, differentials, suspensions, and more.

"Two new titles that are sure winners."

"Each model is built with pieces in a wide range of colours, making it easier to see what parts are used and how they are connected. Pictures from different angles of each build provide enough information to “reverse engineer” all of the contraptions for even the most inexperienced builder. Aside from the introduction the book has virtually no text. The images speak for themselves."
—TechnicBRICKs

"One of the amazing things is that even the most complex of the myriad ideas presented do entirely without programming, but are purely mechanically implemented, often under the aid of only one or at most two motors."
—Die NXTe Ebene

"Brimful of high quality images on beautiful glossy paper."
