Build unique robots that are powered by the sun — batteries not required! Using a compact solar panel these cool little bots harness energy from the sun to power an electric motor to get moving. Build a drummer robot that marches along beating a drum, an armadillo robot that does somersaults, a solar bug that crawls on six legs, a tank robot with tread-like feet, and more! The 44-page, full-color manual guides solar power pioneers through model assembly and offers fun scientific facts about the real-life applications of solar technology. After learning about the amazing amount of energy the sun has to offer, what solar-powered inventions will you dream up?
