Abstract
An articulated coordinate measuring arm having swiveling joints which are unlimited by an end-stops. Power and signals are transmitted through a swiveling joint using a multi-conductor electrical slip-ring sub-assembly. Joint position transducer signal conditioners are closely located to the joint position transducers to reduce signal noise degradation. Rigid transfer members connecting the joints comprise a freely rotating shaft mounted within an outer sheath, wherein both shaft and sheath extend substantially the length of the transfer member, and the shaft outer diameter approaches that of the sheath inner diameter.
