Feasibility study of a robot hand-eye coordination based on fuzzy logic

In a manufacturing environment, the robot calibration process is usually lengthy and time consuming. A robot manipulator with a vision feedback may have to be recalibrated each time the operation position of the robot is changed for a different task or due to random disturbances. In this study, we describe a fuzzy logic algorithm for robot hand-eye coordination without recalibration. The technique is based on the prior calibration of two extreme points. The fuzzy logic algorithm takes care of the unexpected changes in between these two points. This technique offers considerable saving of time without intensive computation of recalibration
