Abstract
A metrology device determines the position of a machine component relative to a datum along three linear and three rotational axes. The metrology device has a pair of support structures connected by six legs that are each disposed at an angle with respect to the next adjacent leg. One of the support structures can be connected to the datum and the other can be connected to the machine component. A sensor cooperates with each leg to sense the actuation of that leg as the support structures move relative to one another. The combination of signals provided by the legs can be used to track movement of the machine component relative to the datum.
