Build 10 motorized models of different kinds of vehicles and machines while learning about belt drives, wheels, and tank treads.Models include a dune racer with tank treads that rambles over rough terrain, a four-wheel-drive ATV with a belt drive and high-grip tires, a conveyer belt, and many more.A 40-page, full-color instruction manual guides model building with clear step-by-step instructions.Additional information explores tracked vehicles: what they are and why they're advantageous in certain situations, like at a construction site or on the snow.The plastic building system is compatible with other kits in the Engineering Makerspace line: combine the pieces to design and create your own vehicles and machines limited only by your imagination.
