Abstract: A method monitors a supply system of a robot having a robot arm and a robot hand movable relative thereto. The supply system has a supply chain, in particular a cable assembly, and a guide for the supply chain. The supply chain is guided along the robot arm in order to supply the robot hand. The supply system also has a number of sensors for monitoring at least one state variable of the supply system. The functional capability of the supply system is concluded, inferred or predicted from values for the state variable that are determined by the sensors.

Abstract: In order to allow, in particular in the case of an industrial robot for a hose assembly to be used, a simply constructed guide element which is flexible is provided. The guide element has longitudinal compensation for the hose assembly and is formed by preferably four guide rods which are distributed uniformly on a circular line and are respectively fastened at their ends to a holding ring. The supply lines running in the hose assembly can be flexibly guided laterally out from the guide element, to any desired sides, between the guide rods. A helical spring which surrounds the hose assembly in the guide element, is provided for a restoring movement.
