Two robot arms work precisely and at high speed at a common workstation. Their distinctive programming allows a high cycle rate while preventing collisions. Sensors on a cleaning robot act like dirt detectives and enable the cleaning device to be active at precisely the point in the factory where the need is particularly great at the moment. The machine independently calculates how much water and cleaning fluid to use. And while production is running, the power supply system regulates the use of cooling and lighting. All this works at the same time when machines, equipment and systems in a smart factory communicate with each other and organize themselves. And all around, there are services in the smart factory that create added value. They, too, must be digitized and smart.
