This kit contains multiple robotic parts that let you build 14 different, moving robots! They run completely off solar power, so you don't need batteries, and they have alternating polarity, letting them move forwards and backwards. The robots have movements based on their shapes, and some are even designed to operate in water! With the solar energy panel and clear gear-housing, the educational value is huge, teaching you about robotics and new power sources all at once! There are 2 different levels, for beginners and advanced builders, letting you build more detailed robots as your knowledge grows. Educational and entertaining for ages 10 and up. As we embrace the era of renewable energy, it's essential to explore how alternative energy sources can power innovative creations! Enter the 14-in-1 solar robot kit, an educational marvel that empowers you to construct a versatile robot from an array of parts. This robot is not limited to land, it can conquer water too! What makes this kit truly remarkable is that it harnesses the power of solar energy, eliminating the need for batteries. The kit offers multiple building levels, with level 1 designed for beginners and level 2 tailored for the experts. You have the ability to control the robot's direction by simply changing the polarity, effectively reversing the direction of its motors. Thanks to the transparent housing, you can peer into the kit and witness the intricate gears in motion, providing an engaging learning experience. The robot's head can be ingeniously stored in various positions, within the body, at the front, top, or rear. This versatile and eco-friendly kit not only promotes STEM learning but also fuels your imagination as you explore the endless possibilities of solar-powered robotics.
