Abstract
This paper presents an experimental study on the use of visual servoing for dexterous robotic manipulation. In the first step of the work, a mathematical model of the whole system has been derived, then a non – linear PID regulator with Smith predictorstructure has been developed. The feedback signal for the controller comes directly from the visual sensor. Some experiments on following with robot end-effector a moving target have been performed, showing efficiency of the control system.This work on visual feedback differs from other similar experiments mainly because the inner architecture of the robotcontroller is assumed unknown, i.e. the inner control loop of the robot has not been modified.
