Abstract

A method and apparatus for controlling the sequential coating of motor-vehicle bodies using a preprogrammed painter-robot is provided. As a result of wear, the signal/response delay times of valves and other control elements deviate from the information stored in the program. According to the subject invention, the actual signal/response delay time is measured and compared with the stored information stored in the program. In the event of unacceptable deviations in the actual verses stored signal/response delay times, the actuating times controlled by the program are changed in response thereto, and signals warning of excessive actual delay time are given.
