Zeiss has developed correlation-free in-line measuring: This system uses standard cameras to detect the robots' deviation from their specified position resulting from temperature influences. These cameras are installed above the in-line cell and track every movement of the Zeiss AIMax cloud sensor without any difficulty.
There are markers on the robot arms and on the base of the in-line cell so that the system can determine the absolute spatial position of the sensors. Thanks to this information and, most importantly, intelligent algorithms, the software developed by Zeiss detects deviations from the standard state and immediately filters these out. With this system, companies must no longer subsequently measure their car body components on a CMM at regular intervals.
