Overview
Robots do not work in isolation. They interact continuously with other
production equipment in a process called interfacing, Figure 10-1.
Vision systems give a robot “eyes” and allow it to perform a wider
variety of tasks. Machine vision systems are built into automated work
cells and are used to determine part orientation, handle measurement, and
inspect parts, among other tasks.
This chapter discusses the principles and components of interfacing,
and covers the functionality and applications of machine vision systems.
