# Pan-Tilt System Design and Implementation
## Introduction to Pan-Tilt Systems
A pan-tilt system is a mechanical assembly that enables rotational movement in two perpendicular axes, typically referred to as pan (horizontal rotation) and tilt (vertical rotation). These systems are widely used in various applications, including surveillance cameras, robotic vision systems, and automated tracking devices.
## Key Components of a Pan-Tilt System
The design of a pan-tilt system involves several critical components:
