Abstract
A novel, portable coordinate measuring machine comprises a multijointed (preferably six and/or seven joints) manually positionable measuring arm for accurately and easily measuring a volume, which in a preferred embodiment, comprises a sphere ranging from six to eight feet in diameter and a measuring accuracy of 2 Sigma +/-0.003 inch. In addition to the measuring arm, the present invention employs a controller (or serial box) which acts as the electronic interface between the arm and a host computer. Additionally, a number of end effector probes are provided that fulfill functions other than measurement only.
