12-in-1 STEM Kids Solar Powered Space Robot Science Kit

EDUCATIONAL SOLAR POWER ROBOT - The mechanical scientific solar-energy 12-in-1 creative transformation DIY engineering kids toy set helps develop a solid strong STEM (Science, Technology, Engineering, Math) learning foundation for boys & girls ages 8+ and up. The sun powered environmentally-friendly toy does not need batteries and help children learn about the impact of solar renewable kinetic electric energy green technology, cultivate problem solving skills and early child brain development. 2 SOURCES OF POWER - Charge and power the engineering robot toys utilizing the solar-power panels added with the toy kit. Without using batteries, the robots uses green technology from the solar panel to collect heat energy from the sun and transform it into electric kinetic energy that drives the mechanical motors so each machine gear can operate smoothly.
