A robot has a plurality of components which can pivot relative to each other, in particular robot arms. Changes in separation between individual points of the robot thereby occur. This must be taken into consideration when guiding the operation cables for robot elements and in particular robot tools. The cables must be capable of accommodating length changes while being loaded to as little extent as possible during motion of the robot so that they have high durability and are not prematurely damaged. In accordance with the invention, a robot having cables extending at least partially on the outside, in particular operation cables for robot tools such as a welding tool, has cables guided in a substantially circular loop at the height of a robot arm which can pivot about an axis of the robot.
