# Pan-Tilt System Design and Implementation
## Introduction to Pan-Tilt Systems
A pan-tilt system is a mechanical platform that enables rotational movement in two axes: horizontal (pan) and vertical (tilt). 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 basic components of a pan-tilt system include:
