# 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 astronomical telescopes.
## Key Components of a Pan-Tilt System
### Mechanical Structure
The mechanical design of a pan-tilt system typically consists of:
1. Base platform for stability
2. Pan axis assembly for horizontal rotation
3. Tilt axis assembly for vertical rotation
4. Mounting interface for payload attachment
### Actuation System
Most pan-tilt systems use either:
– Servo motors for precise angular control
– Stepper motors for open-loop positioning
– DC motors with encoders for continuous rotation
