摘要： A metrology apparatus including an articulated joint having: first and second bodies which can be locked together in a plurality of different angular orientations about a first axis; the first body including a prop which is actuatable by a motor between a retracted configuration at which the first and second bodies are in their locked state, and an extended configuration at which the first and second bodies are held apart by the prop along the first axis such that the first and second bodies are unlocked thereby permitting relative rotation of the first and second bodies, the prop and the second body being magnetically biased toward each other so as to magnetically retain the first and second bodies; and further including at least one supplemental bias member configured to bias the prop towards its retracted configuration.

摘要： An articulated head for facilitating reorientation of a mounted tool, including: a first member for mounting the head on a positioning apparatus; a second member coupled to the first so its orientation relative thereto about a first axis can be changed between, and locked at predefined orientations, the members can be unlocked by separating the members along the first axis for reorientation of the second member about the first axis; a third member coupled to the second so its orientation relative thereto about a second axis can be changed between, and locked at predefined orientations, the second and third members can be unlocked by separating the members along the second axis for reorientation of the third member about the second axis, the first and second axes are not parallel; and a powered mechanism independently controlling separation of the first and second and the second and third members.

摘要： A metrology apparatus includes an indexed articulated joint including: first and second relatively reorientable bodies, respectively having mutually engageable engagement elements, which can be locked together in different angular orientations about a first axis to provide a plurality of angularly indexed positions of the bodies; at least one verification sensor configured to provide a measure of the relative spatial configuration of bodies when in their locked state; and wherein the apparatus is configured such that when the bodies lock together at an indexed position, the sensor measures the relative spatial configuration of the bodies, and wherein information obtained from the measure is compared to calibration information obtained from at least one other measure of the relative spatial configuration of the bodies when the bodies were locked at said indexed position at an earlier point in time, in order to establish information about the state of engagement of the bodies.
