Sound-Activated Walking Crab STEM Kit – Build, Paint & Watch It Walk

This sound-activated walking crab STEM kit combines building, electronics and painting in one project. You assemble the laser-cut wooden parts, connect the electronic components and decorate the crab in your own colors. Clap your hands or make a sound and the built-in sound sensor sets it walking.

Key features

• Laser-cut wooden parts
• Built-in sound sensor triggers the walking motion
• Connect the electronic components yourself
• Paint and decorate the crab as you like

Wiring up the sensor yourself makes it clear how the crab knows when to move, and the painting step means every crab looks different. It is a good pick for builders who want a project that is part engineering, part art and fully interactive at the end. A rewarding project for kids who like both building and decorating.
