A device at flexible robot arms and the like, equipped with at least one flexible member for transmitting pressure media, and of the type intended to contact against and to follow the movement of the robot arm. The purpose of the present invention is to provide a flexible member, which with a minimum of space requirement and with an extremely high and by attachment means substantially unhampered mobility via a machine member with high mobility can transmit pressure media to a tool, e.g. a tool on an industrial robot, whereby there is possibility of visual watch of the flexible member over its entire lenght. This is obtained in that the flexible member (3, 6) at least at the movable portions of the robot arm, consists of a preformed, creased flexible tube, hose or the like, the creased portions (3, 6) of which are formed (bent) in accordance with the shape of the robot arm transversally to its longitudinal direction and intended to contact against and at least partly to enclose the robot arm (1). |
