Build a squid-like robot that moves on a flat surface. He will impress you with his rhythmic movements and his moving tentacles!
How It Works The battery causes the motor shaft to rotate. The weight on the shaft is on one side, so that when the motor is running the weight moves in a circular motion.
Thus, the robot's center of gravity is constantly changing, causing the robot to vibrate rapidly.
The vibrations cause the legs to rise one after the other and the robot to walk.
