Claim 17:
18. A method of manufacturing a robot arm, the method comprising:
obtaining a first structural component designed for fixing the robot arm in its surroundings;
coupling a second structural component to the first structural component for rotational movement relative to the first component about an axis of rotation;
coupling a transmission to at least one of the first or second components, the transmission operable to rotate the second structural component relative to the first structural component;
wherein the transmission comprises a transmission casing;
the first structural component including a casing that comprises at least one integrated cavity for receiving lubricant for the transmission, the integrated cavity sized and configured to compensate for changes in fluid volume experienced by the transmission by adding or removing lubricant;
the at least one cavity comprising at least one opening to an outer side of the first structural component, and having a closure for closing the opening; and
fluidically connecting the at least one cavity to the transmission casing by at least one connecting conduit in the casing of the first structural component.
