Equipping legacy robots with vision: performance, availability and accuracy considerations

Abstract

The purpose of this paper is to investigate alternative ways of connecting vision systems to legacy robots and evaluate impact of this addition on availability and accuracy of the robot. The legacy robots lack high speed data interfaces and it is difficult to add high speed capability by altering hardware or software of the robot controller. Interfacing a high speed data throughput device like a vision system through slow interface of legacy robot impacts the availability of the robot. In this study, alternative connection schemes of robot and vision systems are investigated along with their impact on accuracy and availability.
