Abstract
An industrial robot supports an operating member mounted on the robot hand for carrying out work or monitoring operation on an object. The robot has a sensor which controls the path of movement of the robot hand during the operation. The robot is provided with means which during the work operation investigates whether a quantity, sensed with the aid of the sensor, for example a sudden change in the direction of the path, fulfills a predetermined criterion and, in dependence thereon, interrupts the movement of the robot hand if the criterion is fulfilled.
