It features high-range LED eyes and moving arms.

The circuit you created, by connecting the battery compartment to the gearbox and the robot's head, allows for smooth flow of electric current when the battery is activated.

The "ON" switch activates the circuit and allows electric current to flow to the gearbox and the robot's eyes, bringing the Crazy Robot to life.

This happens because a battery always has two poles, a positive and a negative. The positive pole has very few electrons, while the negative pole has many electrons.

If the positive and negative poles are connected, electrons move to correct the imbalance, creating an electric current. The robot's head and gearbox can then convert the energy from the electric current into motion and light.
