Portable coordinate measurement machine having a handle that includes electronics
A portable articulated arm coordinate measurement machine (AACMM) is provided. The AACMM having a manually positionable articulated arm having first and second ends, the arm including a plurality of connected arm segments, each of the arm segments including at least one position transducer for producing position signals, at least one of the position signals passing between two of the arm segments through a first slip ring assembly. A first a first electronic circuit is provided that receives the position signals. A base section is connected to the second end. A probe assembly includes a probe end and a cover. The cover rotates about an axis extending through the probe assembly, the cover having at least one indentation formed thereon. The probe assembly is connected to the first end. The AACMM measures a three-dimensional coordinate of a point in space associated with the probe end.
