Meet the Tumbling Hedgehog: a cute kit that lets you build your own robotic pet hedgehog. It features 127 pieces and a sound sensor that can be used to program the robot to react to different sounds. This hedgehog can tumble, roll, spin around, and bristle its spines when you make different sounds.
This robotic hedgehog also has light up eyes. By building this robot, you will learn about motors, gears, sensors, and other components.
