ABSTRACT:
A control system for an industrial robot having a hand which traces a pre-stored standard course defining its position and posture and which has a foresight function. The hand is provided with a tool and a work shape sensor, where the tool and the work shape sensor have a known spatial relationship. The foresight function is realized by a control system comprising temporary storing means for temporarily storing a future position and/or posture data of the tool calculated from a sensed position and/or posture data of the present sensor position. The stored data is output after a delayed time interval when it is compared with a pre-stored standard data. When the difference is small, the data is used to control the future position and/or posture of the hand. When the difference is great, an abnormality process is started.
