WindBots Robot Kit

Building a robot without batteries is a breeze with this wind-powered kit! Make 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! Start cranking the generator and watch them go. Put together your 6-in-1 robot in a snap—no need for glue. Easy, snap-together assembly is guided by a detailed 52-page manual. Learn about gear ratios and wind-power tech as you 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-powered 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. A full-color manual guides you in assembling six models one at a time from 100+ pieces. Caution: Contains small parts. 7" x 11" x 4". Ages 8+. Imported.
