Abstract: A system having at least one working device and at least one data processing unit, wherein the working device has at least one sensor unit and is designed and configured for autonomous movement in an environment. The data processing unit includes at least one processor and at least one memory, wherein the data processing unit is designed and configured for determining spatial environment data with the sensor unit, for recognizing at least one object in the spatial environment data, for determining at least one object parameter of the object using at least part of the spatial environment data, and for selecting at least one action of the working device with respect to the object as a function of the at least one determined object parameter.
