Editor's Pick: Build a moving robot from scratch with your kids—it's a rewarding experience. No batteries needed; it runs on sunlight, crawling on the ground or floating on water. The included instructions have simple and advanced steps, so kids around 7-8 years old can follow along and build on their own, while older kids can take on more complex designs. Once built, you can switch up the models for more fun.
