This is a five-in-one building set: a solar car, a wind-powered car, an obstacle-avoidance robot, a transmission tank and a glider. Each model is assembled from plastic parts with a small screwdriver, so kids get hands-on wiring and gear work rather than a snap-together toy. It suits ages 8 to 12 and works well as a family project or a classroom STEM unit. Compared with single-model robot kits, it offers more variety, but the builds are simpler and the solar car depends on direct sunlight.

This STEM kit has 5 build-it-yourself projects: a solar powered car, a wind powered car, an obstacle avoidance robot, a transmission tank and a glider. Kids assemble each model themselves and learn about simple machines and physics along the way.
The components are made with odorless, safe materials. A mini screwdriver and step-by-step instruction manuals are included to help with assembly. The kit is designed for kids ages 8-12, and it works for parent-child activities or as a classroom STEM project.
The kit comes in a gift box. The obstacle avoidance robot needs AA batteries, which are not included.
