# Pan Tilt Unit: The Ultimate Guide to Motion Control Systems
## What is a Pan Tilt Unit?
A pan tilt unit (PTU) is a mechanical device that provides controlled movement in two axes: pan (horizontal rotation) and tilt (vertical rotation). These systems are widely used in various applications where precise angular positioning is required.
PTUs typically consist of:
– A base that provides stability
– A pan mechanism for horizontal rotation
– A tilt mechanism for vertical rotation
– Motors and controllers for precise movement
