KiwiCo Jumping Robot STEM Kit – Robotics Building Set for Kids 9+

Jump into hands-on science with the KiwiCo Jumping Robot kit

This engaging STEM project invites kids to assemble a spring-powered jumping robot and watch it leap with every switch. By combining building, testing, and play, this kit turns simple physics into tangible, shareable moments for curious minds.

What you build and how it works

The central mechanism uses a spring driven by cams. The exterior can be premade or personalized with blank body parts. When placed on a flat surface and powered, the cams extend and release the spring, launching the robot into the air. This setup invites experimentation: changing components can alter height, distance, and movement style.

Two ways to learn and play

• Real-world science: explore potential energy, kinetic energy, and how energy transfers during a hop.
• Build it yourself: assemble the cams, connect the spring mechanism, and snap on the exterior for a custom look.

Creative customization and exploration

• Use the blank body parts and home art supplies to personalize your robot and express style.
• Compare how different designs affect the jump height and trajectory in friendly test sessions.

Size, safety, and family-friendly learning

Designed for ages 9 and up, this kit emphasizes clear steps and guided activity. The parts are sized for small hands and careful assembly, making it suitable for independent projects or guided teamwork.

What to expect when you open the box

Inside you will find the spring mechanism, cams, premade exterior, blank body parts, and simple art supplies. The setup is straightforward and paced to support either solo exploration or collaborative building with a friend or caregiver.
