Robot 4-U is turning STEM into STEAM. That's because, aside from science, technology, engineering, and math, the company's day camps work in a touch of art: the point isn't just to solve problems, but also to get creative. During sessions, children build imaginative projects such as moving artworks or individually controlled robots using carefully placed motors, circuits, and infrared sensors. The end result is a dynamic creation—flowers that rustle in the wind, perhaps, or butterflies that tap dance—which children can enter into an art display or a racing, dancing, or battle-bot challenge.
