Children design and build the STEM robots of their dreams with Gears! Gears! Gears! Robots in Motion. This building set is inspired by the original robot series with special components for designing and building robots, cars and machines that move and transform. Children can follow along with the included STEM activity guide or use their imaginations to devise open-ended builds of their own. They can add rolling treads, spinning eyes and more. Every time they build a new robo creation, children will boost their early engineering, critical-thinking and other essential STEM skills. All included pieces work with all other Gears! building sets. Learning toy is perfect for children ages 5 and up.
