Abstract: Workpiece localization plays a vital role in automation of many important manufacturing processes, such as workpiece setup, refixturing and dimensional inspection. In this paper, we provide a unified treatment of three geometric algorithms for workpiece localization, and develop new techniques to make these local algorithms globally convergent. We also study and analyze, along with extensive simulation results, their performance with respect to convergence and computational efficiency. Finally, we present a method for analyzing reliability of localization solutions and give a lower bound on the number of measurement points needed for reliable recovering of Euclidean transformations.

Robot systems reliability and safety: a review
TL;DR: A review of published literature on robot reliability and safety is presented in this paper, where the literature is classified into three main categories: robot safety, robot reliability, and miscellaneous, and robot safety is further categorized into six classifications: general; accidents; human-factors; safety standards; safety methods; and safety systems/technologies.

- 14 Sep 1990
TL;DR: In this paper, a computer-controlled machine equipped with sensors determines position and orientation of a workpiece with respect to a model of the workpiece, which is stored in a data processing system interfaced to the machine, by determining a transformation in which a sum of squared distances from the points to the corresponding surfaces of the model is minimized.
