# Pan Tilt Unit Overview
## Introduction to Pan Tilt Units
A pan tilt unit (PTU) is a mechanical device that provides controlled movement in two axes: pan (horizontal rotation) and tilt (vertical rotation). These units are widely used in various applications where precise angular positioning is required.
## Key Components of a Pan Tilt Unit
The typical pan tilt unit consists of several essential components:
- Base platform
- Pan mechanism (horizontal rotation)
- Tilt mechanism (vertical rotation)
- Motors (servo, stepper, or DC)
- Control electronics
- Position sensors (encoders or potentiometers)
## Applications of Pan Tilt Units
Surveillance Systems
PTUs are commonly used in security cameras to provide flexible viewing angles and tracking capabilities.
Robotics
Robotic systems utilize pan tilt units for head movement, sensor positioning, and object tracking.
Laser Systems
Precision laser pointing and scanning systems often incorporate high-accuracy PTUs.
Astronomy
Telescope mounts frequently use pan tilt mechanisms for celestial tracking.
## Types of Pan Tilt Units
There are several types of pan tilt units available:
- Motorized PTUs with servo or stepper motors
- Manual PTUs with mechanical adjustment
- Heavy-duty industrial PTUs
- Compact PTUs for small devices
- High-precision PTUs for scientific applications
