    Abstract: The invention relates to a robot cell comprising a protective casing, which surrounds a robot, and at least one station, which is served by the robot. A door assembly is provided on the protective casing in order to, in an open position, provide access to an access opening through which the station from the outside of the protective casing can be served by an operator, and in order to, in a closed position, close the access opening.
