Abstract

In some embodiments, an articulated arm coordinate measurement machine can include a plurality of transfer members and a plurality of articulation members connecting the plurality of transfer members to each other to measure an angle between the transfer members. The machine can additionally include at least one coordinate acquisition member positioned at an end of the articulated arm. Further, the machine can include a harness connected to at least one of the group consisting of the transfer members and the articulation members to support at least a portion of the weight of the transfer members and the articulation members. The harness can also be configured to mount to a human.
