Claim 4:
5. An apparatus for diagnosing problems in a robot system comprising one or more robots, the apparatus comprising:
an interface configured to receive problem messages from the robots of the system;
a processing means configured to:
if a time elapsed between receipt of a subsequent problem message and receipt of an immediately preceding problem message is shorter than a predetermined threshold, add the subsequent problem message to a message set which comprises the immediately preceding problem message, or, if the time elapsed is longer than the predetermined threshold, terminate the message set of the immediately preceding problem message without adding the subsequent problem message, and establish a new message set in which the subsequent problem message is the first message,
identify, in a terminated message set, at least one descriptive data element which is frequent in the problem messages of the terminated message set, and
assign the at least one descriptive data element as a name to the terminated message set; and

a screen configured to output thereon names assigned to, or symbols associated with, each terminated message set such that a distance between symbols of certain terminated message sets having identical descriptive data elements is smaller than between symbols of remaining terminated message sets having different descriptive data elements, and a pointing instrument for selecting names or symbols on the screen.
