Thames & Kosmos WindBots 6-in-1 Engineering STEM Kit | Build 6 Wind-Powered Bots, No Batteries/Electricity Required | Explore Wind Technology, Gear Ratios & More | Full-Color Manual & Experiment Guide

Build six awesome bots that move without any batteries or electricity.

The secret behind these fascinating machines is one of the oldest power sources in the world: wind! A full-color manual guides you in assembling six models one at a time from over 130 pieces.

Build a big-wheel tricycle, quadruped, soaring machine, drilling monster, walking robot, and even a wind-powered yacht.

To make them all go, the kit also includes the pieces to build a hand-processed wind generator.

As you build and experiment, you will learn about how gears transmit power and torque.

Also learn about wind as a power-generating technology — past, present, and future.
