Pan-Tilt Platform for Precision Control Applications

# Pan-Tilt Platform for Precision Control Applications

## Introduction to Pan-Tilt Platforms

Pan-tilt platforms are mechanical systems designed to provide precise angular movement in two axes: pan (horizontal rotation) and tilt (vertical rotation). These platforms have become essential components in various industries where accurate positioning and tracking are required.

## Key Components of a Pan-Tilt System

A typical pan-tilt platform consists of several critical components:

– Base structure
– Rotation mechanisms for both axes
– High-precision motors (servo or stepper)
– Position sensors (encoders or potentiometers)
– Control electronics
– Mounting interface for payload

## Applications of Pan-Tilt Platforms
