Abstract

A coordinate measurement device comprises an articulated arm and a laser scanner assembly. The articulated arm can have a first end, a second end, and a plurality of jointed arm segments therebetween. Each arm segment can define at least one axis of rotation, and a last axis of rotation can be defined by bearings near a distal end of the arm. The laser scanner assembly can couple to the distal end of the arm. The arm can continuously generate trigger signals that are received by the laser scanner and indicate a time at which the arm's position is measured.
