**Product Description:**
The Crab Bionic Robot is a type of multi-legged robot that mimics a crab's movement. In this experiment, the motor provides power to drive the spiral rod and the large gear, which in turn drives the rotation of the shaft, allowing the eight legs to move forward alternately. The multiple legs of the crab robot greatly increase its flexibility in movement. By coordinating the movement of its legs, the robot can maintain its body level, adjust its center of gravity, and enhance stability to prevent tipping over. This DIY project aims to inspire children's curiosity in science, encourage hands-on learning, and keep them engaged away from screens.
**Note:** Two AA batteries are required for operation. Please excuse slight manual measurement errors.
