1. A multidimensional measurement system comprising:
- a tracking unit that emits a laser, the tracking unit having a position represented by spherical coordinates;
a target in communication with the tracking unit, the target having a pitch, a yaw and a roll;
a distance determining module that determines a distance between the tracking unit and the target;
a probe removably affixed to the target, the probe comprising a probe tip that is a distance d from a known location on the target; and
an output device that outputs position information about the probe tip relative to the tracking unit based at least on the pitch, yaw, roll, spherical coordinates distance and distance d.

Abstract
A laser based tracking unit communicates with a target to obtain position information about the target. Specifically, the target is placed at the point to be measured. The pitch, yaw and roll of the target, and the spherical coordinates of the target relative to the tracking unit are then obtained. Then additional information regarding a probe attached to the target reconciled with the above determination to determine a position of a probe tip. The target can be, for example, an active device incorporated into a moveable device such a remote controlled robot.
