what do gears do in fnaf universe

In the Five Nights at Freddy's (FNAF) universe, gears are an essential component of the animatronic characters. They serve multiple purposes, including:

1. Animating the animatronics: Gears are responsible for the movement and articulation of the various parts of the animatronics, such as their arms, legs, head, and jaws. They allow the characters to perform their intended actions and appear lifelike.

2. Mechanism synchronization: Gears help synchronize the movements of different parts of an animatronic character. This coordination ensures that the animatronic's actions, such as waving or dancing, are smooth and realistic.

3. Facial expressions: Gears also contribute to the facial expressions of the animatronics. By controlling the movement of the facial components, such as eyebrows, eyelids, and mouths, gears create different emotive expressions.

4. Sound effects: Gears are sometimes linked to additional mechanisms, such as sound devices. They help generate specific audio cues and effects when the animatronics move or perform actions, enhancing the overall experience for visitors or players.

It's important to note that while gears play a significant role in the FNAF universe, the lore and mechanics of the animatronics in the games might differ slightly, especially as the series progresses and new characters are introduced.
