• The difficulties of introducing robot systems in production line are maintenance of environment and teaching of robot motion. Environ recognition and motion teaching using vision system will greatly improve the difficulties. However, calibration of vision-robot system is tedious and troublesome. Feedback control using vision sensor information will allow robustness against environment and teach by showing. This technique is called visual servo.

Visual servo will allow flexible camera setting, calibration-less system setting, and easy teaching.
