Optical sensing systems for robotic manipulators

The straightforward use of optical sensors and sensing systems can provide information essential to the feedback control of robotic manipulators; these systems can then be made electronically stiff and the position and motion of the end-effector in the work space can be predicted with precision. This paper addresses a problem of comparative analysis of practical possibilities in using vision system for a manufacturing robot. The paper presents a very brief description of several approaches which are being investigated with an outline of their limitations.
