Abstract
A system for measuring caster trail of a wheel. The system comprises position sensing devices for sensing positional signals of the wheel and a data processing system configured to couple to the position sensing devices. The data processing system receives signals from the position sensing devices and determines spatial characteristics of a steering axis of the wheel, a reference plane and the center of a wheel. The system then determines the caster trail based on the spatial characteristics.
