Abstract

A new instrument is described which enables spatial position measurements to be made to single targets or to targets disposed in a known spatial array. In the measurement process the geometrical shape of projected laser beams is used to determine either target direction or position. One application area for this portable instrument is introduced, namely for the in-situ spatial calibration of robot end-effectors.
